Quick Start Up

1.1. Important Safety Information
Please read the IMPORTANT SAFETY INFORMATION below, and all Warning and Caution information elsewhere.
Danger: Indicates a risk of electric shock, which, if not avoided, could result in damage to the equipment and possible injury or death.
This variable speed drive product (drive) is intended for professional incorporation into complete equipment or systems as part of a fixed installation. If installed incorrectly it may present a safety hazard. The drive uses high voltages and currents, carries a high level of stored electrical energy, and is used to control mechanical plant that may cause injury. Close attention is required to system design and electrical installation to avoid hazards in either normal operation or in the event of equipment malfunction. Only qualified electricians are allowed to install and maintain this product.
System design, installation, commissioning and maintenance must be carried out only by personnel who have the necessary training and experience. They must carefully read this safety information and the instructions in this Guide and follow all information
regarding transport, storage, installation and use of the drive, including the specified environmental limitations.
Do not perform any flash test or voltage withstand test on the drive. Any electrical measurements required should be carried out with the drive disconnected.
Electric shock hazard! Disconnect and ISOLATE the drive before attempting any work on it. High voltages are present at the terminals and within the drive for up to 10 minutes after disconnection of the electrical supply. Always ensure by using a suitable multimeter that no voltage is present on any drive power terminals prior to commencing any work.
Where supply to the drive is through a plug and socket connector, do not disconnect until 10 minutes have elapsed after turning off the supply.
Ensure correct earthing connections and cable selection as per defined by local legislation or codes. The drive may have a leakage current of greater than 3.5mA; furthermore the earth cable must be sufficient to carry the maximum supply fault current which normally will be limited by the fuses or MCB. Suitably rated fuses or MCB should be fitted in the mains supply to the drive, according to any local legislation or codes.
Do not carry out any work on the drive control cables whilst power is applied to the drive or to the external control circuits. The “Safe Torque Off” Function does not prevent high voltages from being present at the drives power terminals.
Danger: Indicates a potentially hazardous situation other than electrical, which if not avoided, could result in damage to property.
Within the European Union, all machinery in which this product is used must comply with the Machinery Directive 2006/42/EC, Safety of Machinery. In particular, the machine manufacturer is responsible for ensuring that the electrical equipment complies with EN60204-1 and providing a disconnecting device which must be one of the following types:

• A switch-disconnector, utilization category AC-23B (EN 60947-3).
• A circuit breaker suitable for isolation in accordance with EN 60947-2.
• A disconnector with an integrated auxiliary contact that ensures under all circumstances the switching devices break the load circuit prior to opening of the main contacts of the disconnector (EN 60947-3).

For installation in other regions, conformance with local electrical regulations and codes of practice must be adhered to.
The level of integrity offered by the drive control input functions – for example stop/start, forward/reverse and maximum speed, is not sufficient for use in safety-critical applications without independent channels of protection. All applications where malfunction could cause injury or loss of life must be subject to a risk assessment and further protection provided where needed.
The driven motor can start at power up if the enable input signal is present.
The STOP function does not remove potentially lethal high voltages.
ISOLATE the drive and wait 10 minutes before starting any work on it.
Never carry out any work on the Drive, Motor or Motor cable whilst the input power is still applied.
The drive can be programmed to operate the driven motor at speeds above or below the speed achieved when connecting the motor directly to the mains supply. Obtain confirmation from the manufacturers of the motor and the driven machine about suitability for operation over or under the intended speed range prior to machine start up.
Do not activate the automatic fault reset function on any systems whereby this may cause a potentially dangerous situation.
IP55 and IP66 drives provide their own pollution degree 2 environments. IP20 drives must be installed in a pollution degree 2 environment, mounted in a cabinet with IP54 or better.
The drives are intended for indoor use only.
When mounting the drive, ensure that sufficient cooling is provided. Do not carry out drilling operations with the drive in place, dust and swarf from drilling may lead to damage.
The entry of conductive or flammable foreign bodies should be prevented. Flammable material should not be placed close to the drive.
Relative humidity must be less than 95% (non-condensing). Ensure that the supply voltage, frequency and no. of phases (1 or 3 phase) correspond to the rating of the drive as delivered.
Never connect the mains power supply to the Output terminals U, V, W.
Do not install any type of automatic switchgear between the drive and the motor.
Wherever control cabling is close to power cabling, maintain a minimum separation of 100 mm and arrange crossings at 90 degrees.
Ensure that all terminals are tightened to the appropriate torque setting.
Do not attempt to carry out any repair of the drive. In the case of suspected fault or malfunction, contact your local Bardac Sales Partner for further assistance.
Do not operate the drive with any of the enclosure covers removed.

Mechanical Installation

3.1. General

• The drive should be mounted in a vertical position only, on a flat, flame resistant, vibration free mounting using the integral mounting holes or DIN Rail clip (Frame Size 2 only).
• The drive must be installed in a pollution degree 1 or 2 environment only.
• Do not mount flammable material close to the drive.
• Ensure that the minimum cooling air gaps, as detailed in sections 3.6. Guidelines for Enclosure Mounting (IP20 Units), 3.8. Guidelines for Mounting (IP55 Units) and 3.9. Guidelines for Mounting (IP66 Units) are left clear.
• Ensure that the ambient temperature range does not exceed the permissible limits for the drive given in section 10.1. Environmental.
• Provide suitable clean, moisture and contaminant free cooling air sufficient to fulfil the cooling requirements of the drive.

3.2. Before Installation

• Carefully Unpack the drive and check for any signs of damage. Notify the shipper immediately if any exist.
• Check the drive rating label to ensure it is of the correct type and power requirements for the application.
• To prevent accidental damage always store the drive in its original box until required. Storage should be clean and dry and within the temperature range –40°C to +60°C.

3.3. UL Compliant Installation
Note the following for UL-compliant installation:

• For an up to date list of UL compliant products, please refer to UL listing NMMS.E226333.
• The drive can be operated within an ambient temperature range as stated in section 10.1. Environmental.
• For IP20 units, installation is required in a pollution degree 1 environment.
• For IP55 & IP66 units, installation in a pollution degree 2 environment is permissible.
• UL Listed ring terminals / lugs must be used for all bus bar and grounding connections. Refer to section 10.3. Additional Information for UL Approved Installations on page 71.

3.4. Installation Following a Period of Storage
Where the drive has been stored for some time prior to installation, or has remained without the main power supply present for an extended period of time, it is necessary to reform the DC capacitors within the drive according to the following table before operation.
For drives which have not been connected to the main power supply for a period of more than 2 years, this requires a reduced mains voltage mains voltage to be applied for a time period, and gradually increased prior to operating the drive. The voltage levels relative to the drive rated voltage, and the time periods for which they must be applied are shown in the following table. Following completion of the procedure, the drive may be operated as normal.

Storage Period /Power-OFF Period| Initial Input Voltage Level| Time Period T1| Secondary Input Voltage Level| Time Period T2| Third Input Voltage Level| Time Period T3| Final Input Voltage Level| Time Period T4
---|---|---|---|---|---|---|---|---
Up to 1 Year| 100%| N/A
1 – 2 Years| 100%| 1 Hour| N/A
2 – 3 Years| 25%| 30 Minutes| 50%| 30 Minutes| 75%| 30 Minutes| 100%| 30 Minutes

3.6. Guidelines for Enclosure Mounting (IP20 Units)

• IP20 drives are suitable for use in pollution degree 1 environments, according to IEC-664-1. For pollution degree 2 or higher environments, drives should be mounted in a suitable control cabinet with sufficient ingress protection to maintain a pollution degree 1 environment around the drive.
• Enclosures should be made from a thermally conductive material.
• Ensure the minimum air gap clearances around the drive as shown below are observed when mounting the drive.
• Where ventilated enclosures are used, there should be venting above the drive and below the drive to ensure good air circulation. Air should be drawn in below the drive and expelled above the drive.
• In any environments where the conditions require it, the enclosure must be designed to protect the drive against ingress of airborne dust, corrosive gases or liquids, conductive contaminants (such as condensation, carbon dust, and metallic particles) and sprays or splashing water from all directions.
• High moisture, salt or chemical content environments should use a suitably sealed (non-vented) enclosure.

The enclosure design and layout should ensure that the adequate ventilation paths and clearances are left to allow air to circulate through the drive heatsink. Bardac recommend the following minimum sizes for drives mounted in non-ventilated metallic enclosures:

Drive Size| X
Above & Below| Y
Either Side| Z
Between| Recommended airflow
---|---|---|---|---
mm| in| mm| in| mm| in| m3/min       CFM
2| 75| 2.95| 10| 0.39| 46| 1.81| 0.3| 11
3| 100| 3.94| 10| 0.39| 52| 2.05| 0.9| 31
4| 200| 7.87| 25| 0.98| 70| 2.76| 1.7| 62
5| 200| 7.87| 25| 0.98| 70| 2.76| 2.9| 104
8| 300| 11.81| 100| 3.94| | | 20| 705

NOTE
Dimension Z assumes that the drives are mounted side-by-side with no clearance.
Typical drive heat losses are <3% of operating load conditions.
Above are guidelines only and the operating ambient temperature of the drive MUST be maintained at all times.
3.7. Mounting the Drive – IP20 Units

• IP20 Units are intended for installation within a control cabinet.
• When mounting with screws:
  • Using the drive as a template, or the dimensions shown above, mark the locations for drilling.
  • Ensure that when mounting locations are drilled, the dust from drilling does not enter the drive.
  • Mount the drive to the cabinet backplate using suitable M5 mounting screws.
  • Position the drive, and tighten the mounting screws securely.
• When Din Rail Mounting (Frame Size 2 Only):
  • Locate the DIN rail mounting slot on the rear of the drive onto the top of the DIN rail first.
  • Press the bottom of the drive onto the DIN rail until the lower clip attaches to the DIN rail.
  • If necessary, use a suitable flat blade screw driver to pull the DIN rail clip down to allow the drive to mount securely on the rail.
  • To remove the drive from the DIN rail, use a suitable flat blade screwdriver to pull the release tab downwards, and lift the bottom of the drive away from the rail first.

3.8. Guidelines for Mounting (IP55 Units)

• Before mounting the drive, ensure that the chosen location meets the environmental condition requirements for the drive shown in section 10.1. Environmental on page 68.
• The drive must be mounted vertically, on a suitable flat surface.
• The minimum mounting clearances as shown in the table below must be observed.
• The mounting site and chosen mountings should be sufficient to support the weight of the drives.
• IP55 units do not require mounting inside an electrical control cabinet; however they may be if desired.
• Using the drive as a template, or the dimensions shown above, mark the locations required for drilling.
• Suitable cable glands to maintain the IP protection of the drive are required. Gland sizes should be selected based on the number and size of the required connection cables. Drives are supplied with a plain, undrilled gland plate to allow the correct hole sizes to be cut as required. Remove the gland plate from the drive prior to drilling.

NOTE
Typical drive heat losses are approximately 3% of operating load conditions.
Above are guidelines only and the operating ambient temperature of the drive MUST be maintained at all times.

3.9. Guidelines for Mounting (IP66 Units)

• Before mounting the drive, ensure that the chosen location meets the environmental condition requirements for the drive shown in section 10.1. Environmental.
• The drive must be mounted vertically, on a suitable flat surface.
• The minimum mounting clearances as shown in the table below must be observed.
• The mounting site and chosen mountings should be sufficient to support the weight of the drives.
• Using the drive as a template, or the dimensions shown below, mark the locations required for drilling.
• Suitable cable glands to maintain the ingress protection of the drive are required. Gland holes for power and motor cables are pre-moulded into the drive enclosure, recommended gland sizes are shown above. Gland holes for control cables may be cut as
  required.

The drive should be included within the scheduled maintenance program so that the installation maintains a suitable operating environment, this should include:

• Ambient temperature is at or below that set out in section 10.1. Environmental.
• Heat sink fans freely rotating and dust free.
• The Enclosure in which the drive is installed should be free from dust and condensation; furthermore ventilation fans and air filters should be checked for correct air flow.

Checks should also be made on all electrical connections, ensuring screw terminals are correctly torqued; and that power cables have no signs of heat damage.

Electrical Installation

4.1. Connection Diagram
All power terminal locations are marked directly on the product. IP20 Frame Size 2 – 4 units have AC/DC power input located at the top with the motor and brake resistor connections located at the bottom. All other units have power terminals located at the bottom.
4.1.1. Electrical Power Connections

4.1.2. Control Connections

4.2. Protective Earth (PE) (Ground) Connection
4.2.1. Grounding Guidelines
Adequate safety earthing must be provided in accordance with local wiring rules and codes of practice. The ground terminal of each drive should be connected back to the common safety earth bar to maintain touch potentials within safe limits. The ground terminal of each drive should be individually connected DIRECTLY to the site ground bus bar (through the EMC filter if installed). The drive ground connections should not loop from one drive to another, or to, or from any other equipment. Ground impedance must conform to local industrial safety regulations and/or electrical codes.
To meet UL regulations, UL approved ring crimp terminals should be used for all ground wiring connections. The integrity of all ground connections should be checked periodically.
4.2.2. Protective Earth Conductor
The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply conductors.
4.2.3. Motor Ground
The driven motor must be locally connected to a suitable ground location to maintain touch potentials within safe limits. In addition, the motor ground must be connected to one of the ground terminals on the drive.
4.2.4. Ground Fault Monitoring
As with all inverters, a leakage current to earth can exist. The drive is designed to produce the minimum possible leakage current whilst complying with worldwide standards. The level of current is affected by motor cable length and type, the effective switching
frequency, the earth connections used and the type of RFI filter installed. If an ELCB (Earth Leakage Circuit Breaker) is to be used, the following conditions apply:

• A Type B Device must be used.
• The device must be suitable for protecting equipment with a DC component in the leakage current.
• Individual ELCBs should be used for each drive.

4.2.5. Shield Termination (Cable Screen)
The safety ground terminal provides a grounding point for the motor cable shield. The motor cable shield connected to this terminal (drive end) should also be connected to the motor frame (motor end). Use a shield terminating or EMI clamp to connect the shield to the safety ground terminal.
4.3. Incoming Power Connection
4.3.1. Suitability
All P2 models are designed for use on a single phase or balanced three phase supply depending on the model.
For all models and ratings when working with an IT Supply network, or any power supply type where the phase to earth voltage may exceed the phase to phase voltage (such as ungrounded supplies), the internal EMC filter and surge protection must be disconnected before connecting the supply. Refer to section 10.5. Internal EMC Filter and Varistors – Disconnection Procedure on page 72 for further information.
For three phase supply models, a maximum of 3% imbalance is allowed between phases.
4.3.2. Cable Selection

• For 1 phase ac supply, power should be connected to L1/L, L2/N.
• For a DC Supply, the main power cables should be connected to L1/L, L2/N.
• For 3 phase ac supplies, the mains power cables should be connected to L1, L2, and L3. Phase sequence is not important. Neutral connection is not required.

For compliance with CE and C Tick EMC requirements, refer to section 4.10. Control Terminal Connections on page 24.

• A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the drive  and the main Power Source. The disconnecting device must conform to the local safety code / regulations (e.g. within Europe,
  EN60204-1, Safety of machinery).

• The cables should be dimensioned according to any local codes or regulations. Maximum dimensions for each drive model are given in section 10.2. Input/Output Power and Current Ratings on page 68.

4.3.3. Fuse / Circuit Breaker Selection

• Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming supply line, according to the data in section 10.2. Input/Output Power and Current Ratings on page 68.
• The fuses must comply with any local codes or regulations in place. In general, type gG (IEC 60269) or UL type J fuses are suitable; however in some cases type aR fuses may be required. The operating time of the fuses must be below 0.5 seconds.
• Where allowed by local regulations, suitably dimensioned type B MCB circuit breakers of equivalent rating may be utilised in place of fuses, providing that the clearing capacity is sufficient for the installation.
• The maximum permissible short circuit current at the drive power terminals as defined in IEC60439-1 is 100kA.
• The drive provides thermal and short circuit protection for the connected motor and motor cable.

4.3.4. Optional Input Choke
An optional Input Choke is recommended to be installed in the supply line for drives where any of the following conditions occur:

• The incoming supply impedance is low or the fault level / short circuit current is high.
• The supply is prone to dips or brown outs.
• An unbalanced supply system is used (3 phase drives) where the voltage levels during on load operation exceed the designed 3% capacity of the drive.
• The power supply to the drive is via a busbar and brush gear system (typically overhead Cranes).

In all other installations, an input choke is recommended to ensure protection of the drive against power supply faults.
4.4. Operation of 3 Phase drives from a Single Phase Supply
A special function of P2 allows all drives designed for operation on 3 phase supplies to be operated on a single phase supply of the correct rated voltage at up to 50% of the nominal capacity.
For Example, Model Number P2-64060-3HF4N can be operated on a single phase supply, 380 – 480 volts, with the maximum output current limited to 45 Amps.
The supply must be connected to the L1 and L2 terminals of the drive.
4.5. Operation with DC Power Supply or Common DC Bus
P2 models provide terminals to directly connect to the DC Bus for applications which require this. For further information on using the DC Bus connections, please refer to your Bardac sales Partner.
4.6. Motor Connection

• The drive inherently produces fast switching of the output voltage (PWM) to the motor compared to the mains supply, for motors which have been wound for operation with a variable speed drive then there is no preventative measures required, however if  the quality of insulation is unknown then the motor manufacturer should be consulted and preventative measures may be required.
• The motor should be connected to the drive U, V, and W terminals using a suitable 3 or 4 core cable. Where a 3 core cable is utilised, with the shield operating as an earth conductor, the shield must have a cross sectional area at least equal to the phase conductors when they are made from the same material. Where a 4 core cable is utilised, the earth conductor must be of at least equal cross sectional area and manufactured from the same material as the phase conductors.
• The motor earth must be connected to one of the drive earth terminals to provide a low impedance path for common mode leakage current to return to the drive. This is best achieved in practice by using a cable with suitable shielding which provides a low impedance path at high frequencies, and ensuring correct, low impedance earth bonding of the motor cable at both ends. For further information, refer to section 4.13. EMC Compliant Installation on page 26.

4.7. Motor Terminal Box Connections
Most general purpose motors are wound for operation on dual voltage supplies. This is indicated on the nameplate of the motor. This operational voltage is normally selected when installing the motor by selecting either WYE (STAR) or DELTA connection. WYE (STAR) always gives the higher of the two voltage ratings.

400| 230 / 400| WYE (Star)|

4.8. Connecting a Brake Resistor
P2 units feature an internal brake transistor, fitted as standard for all models. The brake resistor should be connected to the DC+ and BR terminals of the drive.
The brake transistor is enabled using P1-05 (Refer to section 8.1. Parameter Group 2 – Extended Parameters on page 44 for further information).
Software protection against brake resistor overload is carried out within the drive. For correct protection of the brake resistor, the following settings are required:

• Set P1-14 = 201.
• Enter the resistance of the brake resistor in P6-19 (Ohms).
• Enter the power of the brake resistor in P6-20 (kW).

The voltage level at these terminals may exceed 800VDC.
Stored charge may be present after disconnecting the mains power.
Allow a minimum of 10 minutes discharge after power off before attempting any connection to these terminals.
4.9. Control Terminal Wiring

• All analog signal cables should be suitably shielded. Twisted pair cables are recommended.
• Power and Control Signal cables should be routed separately where possible, and must not be routed parallel to each other.
• Signal levels of different voltages e.g. 24 Volt DC and 110 Volt AC, should not be routed in the same cable.
• Maximum control terminal tightening torque is 0.5Nm.
• Control Cable entry conductor size: 0.05 – 2.5mm 2/ 30 – 12 AWG.

4.10. Control Terminal Connections
Example connection schematics are provided in section 7.3. Example Connection Schematics on page 41.
4.10.1. +24VDC Input / Output
When the mains power is applied to the drive, terminal 1 provides a +24VDC output, maximum load 100mA. This may be used to activate digital inputs or provide power to sensors.
When no mains power is applied to the drive, the drive control electronics may be powered from an external +24VDC source. When powered in this way, all analog and digital I/O and communication functions remain operative, however the motor may not be
operated, which allows safe testing and commissioning of the installation without risk of high voltage being present. When powered in this way, the drive requires up to 100mA.
4.10.2. Digital Inputs
Up to five digital inputs are available. The function of the inputs is defined by parameters P1-12 and P1-13, which are explained in section 7. Control Terminal Functions on page 38.
4.10.3. Analog Inputs
Two analog inputs are available, which may also be used as digital Inputs if required. The signal formats are selected by parameters as follows:

• Analog Input 1 Format Selection Parameter P2-30.
• Analog Input 2 Format Selection Parameter P2-33.

These parameters are described more fully in section 8.1. Parameter Group 2 – Extended Parameters on page 44.
The function of the analog input, e.g. for speed reference or PID feedback for example is defined by parameters P1-12 and P1-13.
The function of these parameters and available options are described in section 7. Control Terminal Functions on page 38.
4.10.4. Analog Outputs
Two analog outputs are available, and may be used for 0 – 10 Volt Signal (max load 20mA), 0 – 20mA, 4 – 20mA or a digital +24Volt DC, 20mA output. The parameters to select function and format are as follows.

These parameters are described more fully in section 8.1. Parameter Group 2 – Extended Parameters on page 44.
4.10.5. Relay Outputs
Two relay outputs are available, which may be used to switch external loads up to 5A at 230 VAC or 6A at 30VDC.
Relay 1 has both normally open and normally closed contacts available. Relay 2 provides a simple open or closed contact.
The relay output function may be configured using parameters P2-15 and P2-18, which are described in section 8.1. Parameter Group 2 – Extended Parameters on page 44.

4.11. IP66 Switched Version Integrated Control Switch and Potentiometer Wiring
The P2 is optionally available with an integrated mains disconnect / isolator and front mounted control switch and potentiometer. This allows the drive to be operated directly from the front control panel, whilst also providing for options such as Hand / Auto or Local / Remote Control etc.
The built in switch and pot are wired inside the terminal cover directly to the user control terminals as shown in the diagram below.
These connections may be disconnected by the user if they are not required. The control switch activates the first two digital inputs as follows: 4.12. Motor Thermal Overload Protection
4.12.1. Internal Thermal Overload Protection
The drive has an in-built motor thermal overload function; this is in the form of an “I.t-trP” trip after delivering >100% of the value set in P-08 for a sustained period of time (e.g. 150% for 60 seconds).
4.12.2. Motor Thermistor Connection
Where a motor thermistor is to be used, it should be connected as follows:

| Compatible Thermistor: PTC Type, 2.5kΩ trip level.
Use a setting of P1-13 that has Input 5 function as E-TRIP “External Trip”, e.g. P1-13 = 6. Refer to section 7.2. Digital Input Configuration Parameter P1-13 on page 39 for further details.
Enable the Motor PTC Thermistor Input function in parameter P2-33.

1. A screened (shielded) cable suitable for fixed installation with the relevant mains voltage in use. Braided or twisted type screened cable where the screen covers at least 85% of the cable surface area, designed with low impedance to HF signals. Installation of a standard cable within a suitable steel or copper tube is also acceptable.
2. A cable suitable for fixed installation with relevant mains voltage with a concentric protection wire. Installation of a standard cable within a suitable steel or copper tube is also acceptable.
3. A cable suitable for fixed installation with relevant mains voltage. A shielded type cable is not necessary.
4. A shielded cable with low impedance shield. Twisted pair cable is recommended for analog signals.
5. The cable shield should be terminated at the motor end using an EMC type gland allowing connection to the motor body through the largest possible surface area. The shield must also be terminated at the drive end, as close as practically possible to the drive output terminals. Where drives are mounted in a steel control panel enclosure, the cable screen may be terminated directly to the control panel backplate using a suitable EMC clamp or gland fitted as close to the drive as possible. The drive earth terminal must also be connected directly to this point, using a suitable cable which provides low impedance to high frequency currents. For IP55 and IP66 drives, connect the motor cable shield to the gland plate or internal ground clamp.
6. 230 Volt, 1 phase input drives using internal EMC filter. Other models require external EMC filter.
7. Compliance with category C1 conducted emissions only is achieved. For compliance with category C1 radiated emissions, additional measures may be required, contact your Sales Partner for further assistance.
8. EMC categories for drives with internal filter EMC filter and rated voltage less than 480 Volts. For other drives, additional EMC filtering is required.
9. Permissible cable length with additional external EMC filter.

4.13.3. Enclosed Drives Recommended Cable Connections

4.14. Safe Torque Off
Safe Torque OFF will be referred to as “STO” through the remainder of this section.
4.14.1. Responsibilities
The overall system designer is responsible for defining the requirements of the overall “Safety Control System” within which the drive will be incorporated; furthermore the system designer is responsible for ensuring that the complete system is risk assessed and that the “Safety control System” requirements have been entirely met and that the function is fully verified, this must include confirmation testing of the “STO” function before drive commissioning.
The system designer shall determine the possible risks and hazards within the system by carrying out a thorough risk and hazard analysis, the outcome of the analysis should provide an estimate of the possible hazards, furthermore determine the risk levels and identify any needs for risk reduction. The “STO” function should be evaluated to ensure it can sufficiently meet the risk level required.
4.14.2. What STO Provides
The purpose of the “STO“ function is to provide a method of preventing the drive from creating torque in the motor in the absence of the “STO“ input signals (Terminal 12 with respect to Terminal 13), this allows the drive to be incorporated into a complete safety
control system where “STO“ requirements need to be fulfilled.

1. The “STO“ function can typically eliminate the need for electro-mechanical contactors with cross-checking auxiliary contacts as per  normally required to provide safety functions.
2. The drive has the “STO“ function built-in as standard and complies with the definition of “Safe torque off“ as defined by IEC 61800-52:2007.

The “STO“ function also corresponds to an uncontrolled stop in accordance with category 0 (Emergency Off), of IEC 60204-1. This means that the motor will coast to a stop when the “STO” function is activated, this method of stopping should be confirmed as being acceptable to the system the motor is driving.
The “STO“ function is recognised as a fail-safe method even in the case where the “STO“ signal is absent and a single fault within the drive has occurred, the drive has been proven in respect of this by meeting the following safety standards:

| SIL
(Safety Integrity Level)| PFHD
(Probability of dangerous
Failures per Hour)| SFF
(Safe failure fraction %)| Lifetime assumed
---|---|---|---|---
EN 61800-5-2| 2| 1.23E-09 1/h (0.12 % of SIL 2)| 50| 20 Yrs
| PL
(Performance Level)| CCF (%)
(Common Cause Failure)| MTTFd| Category
---|---|---|---|---
EN ISO 13849-1| PL d| 1| 4525a| 3
| SILCL
---|---
EN 62061| SILCL 2

NOTE The values achieved above maybe jeopardised if the drive is installed outside of the Environmental limits detailed in section 10.1. Environmental.
4.14.3. What STO Does Not Provide

__

__

__

__

__

| Disconnect and ISOLATE the drive before attempting any work on it. The “STO“ function does not prevent high voltages from being present at the drive power terminals.
---|---
1 NOTE The “STO“ function does not prevent the drive from an unexpected re-start. As soon as the “STO“inputs receive the relevant signal it is possible (subject to parameter settings) to restart automatically, Based on this, the function should not be used for carrying out short-term non- electrical machinery operations (such as cleaning or maintenance work).
2 NOTE In some applications additional measures may be required to fulfil the systems safety function needs: the “STO“ function does not provide motor braking. In the case where motor braking is required a time delay safety relay and/or a mechanical brake arrangement or similar method should be adopted, consideration should be made over the required safety function when braking as the drive braking circuit alone cannot be relied upon as a fail safe method.
When using permanent magnet motors and in the unlikely event of a multiple output power devices failing then the motor could effectively rotate the motor shaft by 180/p degrees (Where p denotes number of motor pole pairs).

4.14.4. “STO“ Operation
When the “STO” inputs are energised, the “STO” function is in a standby state, if the drive is then given a “Start signal/command” (as per the start source method selected in P1-13) then the drive will start and operate normally.
When the “STO” inputs are de-energised then the STO Function is activated and stops the drive (Motor will coast), the drive is now in “Safe Torque Off” mode.
To get the drive out of “Safe Torque Off” mode then any “Fault messages” need to be reset and the drive “STO” input needs to be re-energised.
4.14.5. “STO” Status and Monitoring
There are a number of methods for monitoring the status of the “STO” input, these are detailed below:
Drive Display
In Normal drive operation (Mains AC power applied), when the drives “STO” input is de-energised (“STO” Function activated) the drive will highlight this by displaying “InHibit”, (NOTE If the drive is in a tripped condition then the relevant trip will be displayed and not “InHibit”).
Drive Output Relay

• Drive relay 1: Setting P2-15 to a value of “13” will result in relay opening when the “STO” function is activated.
• Drive relay 2: Setting P2-18 to a value of “13” will result in relay opening when the “STO” function is activated.

“STO” Fault Codes

4.14.6. “STO” Function Response Time
The total response time is the time from a safety related event occurring to the components (sum of) within the system responding and becoming safe. (Stop Category 0 in accordance with IEC 60204-1).

• The response time from the “STO” inputs being de-energised to the output of the drive being in a state that will not produce torque in the motor (“STO” active) is less than 1ms.
• The response time from the “STO” inputs being de-energised to the “STO” monitoring status changing state is less than 20ms.
• The response time from the drive sensing a fault in the STO circuit to the drive displaying the fault on the display/Digital output showing drive not healthy is less than 20ms.

4.14.7. “STO“ Electrical Installation

The “STO” wiring shall be protected from inadvertent short circuits or tampering which could lead to failure of the “STO” input signal, further guidance is given in the diagrams below.
In addition to the wiring guidelines for the “STO” circuit below, section 4.13.1. Recommended Installation for EMC Compliance on page 26 should also be followed.
The drive should be wired as illustrated below; the 24Vdc signal source applied to the “STO” input can be either from the 24Vdc on the drive or from an External 24Vdc power supply.
4.14.8. Recommended “STO” Wiring NOTE The Maximum cable length from Voltage source to the drive terminals should not exceed 25 mtrs.
4.14.9. External Power Supply Specification

4.14.10. Safety Relay Specification
The safety relay should be chosen so that at minimum it meets the safety standards in which the drive meets.

4.14.11. Enabling the “STO” Function
The “STO” function is always enabled in the drive regardless of operating mode or parameter changes made by the user.

Standard Requirements| SIL2 or PLd SC3 or better (With Forcibly guided Contacts)
---|---
Number of Output Contacts| 2 independent
Switching Voltage Rating| 30Vdc
Switching Current| 100mA

4.14.12. Testing the “STO” Function
Before commissioning the system the “STO” function should always be tested for correct operation, this should include the following tests:

• With the motor at standstill, and a stop command given to the drive (as per the start source method selected in P1-13):
  • De-energise the “STO” inputs (Drive will display ““InHibit”).
  • Give a start command (as per the start source method selected in P1-13) and check that the drive still displays “Inhibit” and that the operation is in line with the section 4.14.4. “STO“ Operation and section 4.14.5. “STO” Status and Monitoring.
• With the motor running normally (from the drive):
  • De-energise the “STO” inputs.
  • Check that the drive displays “Inhibt” and that the motor stops and that the operation is in line with the section and section 4.14.4. “STO“ Operation and section 4.14.5. “STO” Status and Monitoring.

4.14.13. “STO” Function Maintenance
The “STO” function should be included within the control systems scheduled maintenance program so that the function is regularly tested for integrity (Minimum once per Year), furthermore the function should be integrity tested following any safety system
modifications or maintenance work. If drive fault messages are observed refer to section 11.1. Fault Messages on page 74 for further guidance.

5.6. Parameter Factory Reset / User Reset
The P2 provides a feature to allow the user to define their own default parameter set. After commissioning all required parameters, the user can save these as the defaul parameters by setting P6-29 = 1. If required, the User Default Parameters may be cleared by setting P6-29 = 2.
If the user wishes to relaod the User Default Parameters from the drive memory, the following procedure is used.

5.7. Resetting the Drive Following a Trip
The P2 has many protection features, designed to protect both the drive and motor from accidental damage. When any of these protection features are activated, the drive will trip, and display a fault message. The fault messages are listed in section 11.1. Fault
Messages on page 74.
When a trip occurs, after the cause of the trip has been investigated and rectified, the user can reset the trip in one of the following ways:

• Press the keypad Stop key.
• Power off the drive completely, then power on again.
• If P1-13 > 0, switch off digital input 1, then back on again.
• If P1-12 = 4, reset via the fieldbus interface.
• If P1-12 = 6, reset via CAN.

5.8. Keypad Short Cuts
The following short cuts can be used to speed up selecting and changing parameters when using the keypad.
5.8.1. Selecting the Parameter Groups

Parameters

6.1. Parameter Set Overview
The P2 Parameter set consists of 10 groups as follows:

• Group 0 – Read Only Monitoring Parameters
• Group 1 – Basic Configuration Parameters
• Group 2 – Extended Parameters
• Group 3 – PID Control Parameters
• Group 4 – High Performance Motor Control Parameters
• Group 5 – Field Bus Parameters
• Group 6 – Advanced Options
• Group 7 – Advanced Motor Control
• Group 8 – Application Parameters
• Group 9 – Advanced I/O Selection

When the drive is reset to factory defaults, or is in its factory supplied state, only Group 1 Parameters can be accessed. In order to allow access to parameters from the higher level groups, the access code must be changed as follows.
P1-14 = P2-40 (Default setting = 101). With this setting, parameter groups 1 – 5 can be accessed, along with the first 50 parameters in Group 0.
P1-14 = P6-30 (Default setting = 201). With this setting, all parameters are accessible.

6.2. Parameter Group 1 – Basic Parameters
The basic parameter group allows the user to:

• Enter the motor nameplate information
  o P1-07 = Motor Rated Voltage
  o P1-08 = Motor Rated Current
  o P1-09 = Motor Rated Frequency
  o P1-10 = (Optionally) Motor Rated Speed

• Define the operating speed limits
  o P1-01 = Maximum Frequency or Speed
  o P1-02 = Minimum Frequency or Speed

• Define the acceleration and deceleration times used when starting and stopping the motor, or changing speed
  o P1-03 = Acceleration Time
  o P1-04 = Deceleration Time

• Select where the drive should receive it’s command signals from, and determine what functions are associated with the drive control terminal inputs
  o P1-12 Selects the control source
  o P1-13 Assigns the functions to the digital inputs

These parameters will often provide enough functions to allow the user to complete basic commissioning in simple applications. The parameters are described more fully below.

Par.| Description| Minimum| Maximum| Default| Units
---|---|---|---|---|---
P1-01| Maximum Frequency / Speed Limit| P1-02| 500.0| 50.0 (60.0)| Hz / Rpm

Par.| Description| Minimum| Maximum| Default| Units
---|---|---|---|---|---
P1-04| Deceleration Ramp Time| See Below| 5.0 / 10.0| Seconds
Deceleration ramp time from base speed (P1-09) to standstill in seconds. When set to zero, fastest possible ramp time without trip is activated.
FS2 & FS3 : 5.0 Seconds Default Setting, 0.01 Seconds Resolution, 600.0 Seconds Maximum. FS4 – FS7 : 10.0 Seconds Default Setting, 0.1 Seconds Resolution, 6000.0 Seconds Maximum.
P1-05| Stop Mode| 0| 3| 0| –
0| Ramp To Stop| When the enable signal is removed, the drive will ramp to stop, with the rate controlled by P1-04 as described above. In this mode, the drive brake transistor (where fitted) is disabled.
1| Coast to Stop| When the enable signal is removed, the drive output is immediately disabled, and the motor will coast (freewheel) to stop. If the load can continue to rotate due to inertia, and the drive may possibly be re-enabled whilst the motor is still rotating, the spin start function (P2-26) should be enabled. In this mode, the drive brake transistor (where fitted) is disabled.
2| Ramp To Stop| When the enable signal is removed, the drive will ramp to stop, with the rate controlled by P1-04 as described above. The drive brake chopper is also enabled in this mode.
3| Coast to Stop| When the enable signal is removed, the drive output is immediately disabled, and the motor will coast (freewheel) to stop. If the load can continue to rotate due to inertia, and the drive may possibly be re-enabled whilst the motor is still rotating, the spin start function (P2- 26) should be enabled. The drive brake chopper is enabled in this mode, however it will only activate when required during a change in the drive frequency setpoint, and will not activate when stopping.
4| AC Flux Braking| As Option 0, but additionally, AC Flux braking is used to increase the available braking torque.
P1-06| Energy Optimiser| 0| 1| 0| –
0| Disabled|
1| Enabled| When enabled, the Energy Optimiser attempts to reduce the overall energy consumed by the drive and motor when operating at constant speeds and light loads. The output voltage applied to the motor is reduced. The Energy Optimiser is intended for applications where the drive may operate for some periods of time with constant speed and light motor load, whether constant or variable torque.
P1-07| Motor Rated Voltage| Drive Rating Dependent| Volts
This parameter should be set to the rated (nameplate) voltage of the motor (Volts).
P1-08| Motor Rated Current| Drive Rating Dependent| Amps
This parameter should be set to the rated (nameplate) current of the motor.
P1-09| Motor Rated Frequency| 10| 500| 50 (60)| Hz
This parameter should be set to the rated (nameplate) current of the motor.
P1-10| Motor Rated Speed| 0| 30000| 0| RPM
This parameter can optionally be set to the rated (nameplate) rpm of the motor. When set to the default value of zero, all speed related parameters are displayed in Hz, and the slip compensation for the motor is disabled. Entering the value from the motor nameplate enables the slip compensation function, and the drive display will now show motor speed in estimated rpm. All speed related parameters, such as Minimum and Maximum Speed, Preset Speeds etc. will also be displayed in Rpm.
NOTE When the drive is operated with the optional Encoder Feedback Interface, this parameter must be set to the correct nameplate Rpm of the connected motor.
P1-11| V/F Mode Voltage Boost| 0.0| Drive Rating Dependent| %
Voltage boost is used to increase the applied motor voltage at low output frequencies, in order to improve low speed and starting torque. Excessive voltage boost levels may result in increased motor current and temperature, and force ventilation of the motor may be required.
An automatic setting ( ) is also possible, whereby the drive will automatically adjust this parameter based on the motor parameters measured during an autotune.
Par.| Description| Minimum| Maximum| Default| Units
---|---|---|---|---|---
P1-12| Primary Command Source| 0| 6| 0| –
0| Terminal Control| The drive responds directly to signals applied to the control terminals.
1| Uni-directional Keypad Control| The drive can be controlled in the forward direction only using an external or remote Keypad.
2| Bi-directional Keypad Control| The drive can be controlled in the forward and reverse directions using an external or remote Keypad. Pressing the keypad START button toggles between forward and reverse.
3| PID Control| The output frequency is controlled by the internal PID controller.

P1-14 = P2-40 = 101 : Allows access to Extended Parameter Groups 0 – 5
P1-14 = P6-30 = 201 = Allows access to all parameter groups (Intended for experienced users only, usage is not described in this User Guide).

Control Terminal Functions

For standard applications and operation, the basic control of the drive and functions of all drive input terminals can be configured using just two parameters, P1-12 and P1-13. P1-12 is used to define the source of all control commands and the primary speed
reference source. P1-13 then allows fast selection of Analog and Digital Input functions based on a selection table.

7.1. Control Source Selection
7.1.1. P1-12 Function
P1-12 is used to select the main control source of the drive and the main speed reference according to the following table:

P1-12| Function| Control Source| Main Speed Reference| Notes
---|---|---|---|---
0| Terminal Control| Terminals| Analog Input 1| All control signals are applied to the control terminals. Functions are determined by P-15 Macro setting.
1| Keypad Control| Keypad / Terminals| Motorised Pot / Keypad| When keypad mode is selected, the default operation of the drive requires the keypad Start & Stop buttons are used to control the drive. This can be changed using P-31 to allow the drive to be started from Digital Input 1 directly.
2| Keypad Control| Keypad / Terminals| Motorised Pot / Keypad
3| PID Control| Terminals| PID Output| Enable / Disable control of the drive is through the drive control terminal strip.
Output frequency is set by the output of the PI Controller.
4| Fieldbus / Modbus RTU| Modbus RTU| Fieldbus / Modbus RTU| Control of the drive operation is through a fieldbus option module mounted in the drive option slot. If no option module is fitted, control is through the Modbus RTU interface.
Digital Input 1 must be closed to allow operation.
5| Slave Mode| Master Drive| From Master| The P2 provides an inbuilt Master / Slave function. A single drive acts as the Master, and connected Slave drives will mimic the starting and stopping, along with the following the output frequency, with any scaling applied.
Digital Input 1 must be closed to allow operation.
6| CAN Open| CAN Open| CAN| Control of the drive operation is through the CAN Open Interface. Digital Input 1 must be closed to allow operation.

7.1.2. Overview
The P2 uses a Macro approach to simplify the configuration of the Analog and Digital Inputs. There are two key parameters which determine the input functions and drive behaviour:

• P1-12 – Selects the main drive control source and determines how the output frequency of the drive is primarily controlled.

• P1-13 – Assigns the Macro function to the analog and digital inputs.
  Additional parameters can then be used to further adapt the settings, e.g.

• P2-30 – Used to select the format of the analog signal to be connected to analog input 1, e.g. 0 – 10 Volt, 4 – 20mA.

• P2-33 – Used to select the format of the analog signal to be connected to analog input 2, e.g. 0 – 10 Volt, 4 – 20mA.

• P2-36 – Determines whether the drive should automatically start following a power on if the Enable Input is present.

• P2-37 – When Keypad Mode is selected, determines at what output frequency / speed the drive should start following the enable command, and also whether the keypad start key must be pressed or if the Enable input alone should start the drive.

The diagrams opposite provide an overview of the functions of each terminal macro function, and a simplified connection diagram for each.

8.2. Parameter Group 3 – PID Control
8.2.1. Overview
The P2 provides an internal PID controller. Parameters for configuration of the PID controller are located together in Group 3. For simple applications, the user needs to only define the setpoint source (P3-05 to select the source or P3-06 for a fixed setpoint),
feedback source (P3-10) and adjust the P Gain (P3-01), I time (P3-02) and optionally the differential time (P3-03).
The PID operation is uni-directional, and all signals are treated as 0 – 100% to provide a simple, intuitive operating format.

Where the feedback is provided from a transducer such as a pressure transducer or level measurement, this represents the percentage of the pressure range (e.g. for a 0 – 10 Bar transducer, 4 bar = 40%) or the level.
P3-07| PID Controller Output Upper Limit| P3-08| 100.0| 100.0| %

Limits the minimum output from the PID controller.
P3-09| PID Output Limit Control| 0| 3| 0| –
0| Digital Output Limits| The output range of the PID controller is limited by the values of P3-07 & P3-08.

   P3-11| Maximum PID Error to Enable Ramps| 0.0| 25.0| 0.0| %
   Defines a threshold PID error level, whereby if the difference between the setpoint and feedback values is less than the set threshold, the internal ramp times of the drive are disabled. Where a greater PID error exists, the ramp times are enabled to limit the rate of change of motor speed on large PID errors, and react quickly to small errors.
   Setting to 0.0 means that the drive ramps are always enabled. This parameter is intended to allow the user to disable the drive internal ramps where a fast reaction to the PID control is required, however by only disabling the ramps when a small PID error exists, the risk of possible over current or over voltage trips being generated are reduced.
   P3-12| PID Feedback Value Display Scaling Factor| 0.000| 50.000| 0.000| –
   Applies a scaling factor to the displayed PID feedback, allowing the user to display the actual signal level from a transducer, e.g. 0 – 10 Bar etc.
   P3-13| PID Error Wake Up Level| 0.0| 100.0| 5.0| %
   Sets a programmable level whereby if the drive enters standby motor whilst operating under PID control, the selected feedback signal must fall below this threshold before the drive will return to normal operation.
   P3-18| PID Operation Control| 0| 1| 1| –
   0| Continuous PID Operation| In this operating mode, the PID controller operates continuously, regardless of whether the drive is enabled or disabled. This can result in the output of the PID controller reaching the maximum level prior to the drive enable signal being applied.
   1| PID operation on Drive Enable| In this operating mode, the PID controller only operates when the drive is enabled, and hence will always start from zero when the drive is enabled.

8.2.3. Parameter Group 4 – High Performance Motor Control Overview
Parameters relating to the motor control are located together in Group 4. These parameters allow the user to:

• Select the motor type to match the connected motor.
• Carry out an autotune.
• Define the torque limits and setpoint source for control methods that support this (vector control methods only).

The P2 can operate with both Asynchronous Induction Motors, the type most commonly seen today, and also some synchronous motors. The sections below provide basic guidance on how to adjust the parameters to operate with the required motor type.

8.2.4. Asynchronous IM Motors
IM Motor Control Methods
IM Motors may be operated in the following modes:

• V/F Speed Control (Default Mode)
  o This mode provides the simplest control, and is suitable for a wide range of applications.

• Sensorless Vector Torque Control
  o This method is suitable for specific applications only, which require the motor torque to be the primary control function, rather than speed, and should be used with extreme care only in specific applications.

• Sensorless Vector Speed Control
  o This method provides increased starting torque compared to V/F mode, along with improved motor speed regulation with changing load conditions. This method is suitable for more demanding applications.

Operating in Sensorless Vector Speed Control Mode
The P2 can be programmed by the user to operate in Sensorless Vector mode, which provides enhanced low speed torque, optimum motor speed regulation regardless of load and accurate control of the motor torque. In most applications, the default Voltage Vector control mode will provide adequate performance, however if Sensorless Vector operation is required, use the following procedure.

• Ensure advanced parameter access is enabled by setting P1-14 = 101.

• Enter the motor nameplate details into the relevant parameters as follows:
  o P1-07 Motor Rated Voltage
  o P1-08 Motor Rated Current
  o P1-09 Motor Rated Frequency
  o (Optional) P1-10 Motor Rated Speed (Rpm)
  o P4-05 Motor Power Factor.

• Select Sensorless Vector Speed Control mode by setting P4-01 = 0.

• Ensure that the motor is correctly connected to the drive.

• Carry out a motor data Autotune by setting P4-02 = 1.

The Autotune will begin immediately when P4-02 is set regardless of the status of the drive enable signal. Whilst the autotune procedure does not drive or spin the motor, the motor shaft may still turn slightly. It is not normally necessary to uncouple the load from the motor; however the user should ensure that no risk arises from the possible movement of the motor shaft.
It is essential that the correct motor data is entered into the relevant drive parameters. Incorrect parameter settings can result in poor or even dangerous performance.

8.2.5. Synchronous Motors
Overview
The P2 provides open loop vector control of the following synchronous motor types.
PM AC Permanent Magnet AC Motors and BLDC Brushless DC Motors
The P2 can be used to control Permanent Magnet AC or Brushless DC motors without a feedback encoder or resolver. These motors operate synchronously, and a vector control strategy is used to maintain correct operation. In general, the motor can be operated
between 10% – 100% of rated speed with a correctly selected and configured drive. Optimum control is achieved when the motor back EMF / Rated speed ratio is >= 1V/Hz. Motors with Back EMF / Rated frequency ratio below this level may not operate correctly, or may operate only with reduced speed range.
PM AC and BLDC motor control employs the same strategy, and the same commissioning method is applied.

Permanent Magnet motors (including BLDC) produce an output voltage known as the Back EMF when the shaft is rotated.
The user must ensure that the motor shaft cannot rotate at a speed where this Back EMF exceeds the voltage limit for the drive, otherwise damage can occur.

The following parameter settings are necessary before attempting to operate the motor.

• Ensure advanced parameter access is enabled by setting P1-14 = 101.

• Enter the motor nameplate details into the relevant parameters as follows:
  o P1-07 Back EMF at Rated Frequency / Speed (kE)
  This is the voltage imposed by the magnets at the drive output terminals when the motor operates at rated frequency or speed.
  Some motors may provide a value for volts per thousand RPM, and it may be necessary to calculate the correct value for P1-07.
  o P1-08 Motor Rated Current.
  o P1-09 Motor Rated Frequency.
  o (Optional) P1-10 Motor Rated Speed (Rpm).

• Select PM Motor Speed control mode by setting P4-01 = 3 or BLDC Motor Speed Control by setting P4-01 = 5.

• Ensure that the motor is correctly connected to the drive.

• Carry out a motor data Autotune by setting P4-02 = 1.
  o The autotune measures the electrical data required from the motor to ensure good control.

• To improve motor starting and low speed operation, the following parameters may require adjustment:
  o P7-14: Low Frequency Torque Boost Current: Injects additional current into the motor to help rotor alignment at low output frequency. Set as % of P1-08.
  o P7-15: Low Frequency Torque Boost Frequency Limit: Defines the frequency range where the torque boost is applied. Set as % of P1-09.

Following the steps above, it should be possible to operate the motor. Further parameter settings are possible to enhance the performance if required, please refer to your Bardac Sales Partner for more information.

8.2.6. Syn RM Synchronous Reluctance Motors
When operating with Synchronous Reluctance motors, carry out the following steps:

• Ensure advanced parameter access is enabled by setting P1-14 = 101.

• Enter the motor nameplate details into the relevant parameters as follows:
  o P1-07 Motor Rated Voltage.
  o P1-08 Motor Rated Current.
  o P1-09 Motor Rated Frequency.
  o (Optional) P1-10 Motor Rated Speed (Rpm).
  o P4-05 Motor Power Factor.

• Select Synchronous Reluctance Motor Control mode by setting P4-01 = 6.

• Ensure that the motor is correctly connected to the drive.

• Carry out a motor data Autotune by setting P4-02 = 1.

8.2.7. Group 4 Parameter Listing
Incorrect adjustment of parameters in menu group 4 can cause unexpected behaviour of the motor and any connected machinery. It is recommended that these parameters are only adjusted by experienced users.

Par| Parameter Name| Minimum| Maximum| Default| Units
---|---|---|---|---|---
P4-01| Motor Control Mode| 0| 6| 2| –
Setting| Motor Type| Primary Control| Control Method| Additional Information
0| IM| Speed| Vector| Speed control with Torque Limit. Torque Limit Source selected by P4-06.
1| IM| Torque| Vector| Torque Control with Speed Limit. Torque reference selected by P4-06. Speed Limit defined by the Speed Reference.
2| IM| Speed| V/F| V/F control for simple applications with standard IM Motors.
3| AC PM| Speed| Vector| For speed control of AC PM motors with Sinusoidal back EMF.
4| AC PM| Torque| Vector| For torque control of AC PM motors with Sinusoidal back EMF.
5| BLDC| Speed| Vector| For speed control of BLDC motors with Trapezoidal back EMF.
6| Syn RM| Speed| Vector| For speed control of Synchronous Reluctance motors.
P4-02| Motor Parameter Auto-tune Enable| 0| 1| 0| –
When set to 1, the drive immediately carries out a non-rotating autotune to measure the motor parameters for optimum control and efficiency. Following completion of the autotune, the parameter automatically returns to 0.
P4-03| Vector Speed Controller Proportional Gain| 0.1| 400.0| 25.0| %
Sets the proportional gain value for the speed controller when operating in Vector Speed or Vector Torque motor control modes (P4-01 = 0 or 1). Higher values provide better output frequency regulation and response. Too high a value can cause instability or even over current trips. For applications requiring best possible performance, the value should be adjusted to suit the connected load by gradually increasing the value and monitoring the actual output speed of the load until the required dynamic behaviour is achieved with little or no overshoot where the output speed exceeds the setpoint.
In general, higher friction loads can tolerate higher values of proportional gain, and high inertia, low friction loads may require the gain to be reduced.
P4-04| Vector Speed Controller Integral Time Constant| 0.000| 2.000| 0.050| s
Sets the integral time for the speed controller. Smaller values provide a faster response in reaction to motor load changes, at the risk of introducing instability. For best dynamic performance, the value should be adjusted to suit the connected load.
P4-05| Motor Power Factor Cos Ø| 0.50| 0.99| –| –
When operating in Vector Speed motor control modes, this parameter must be set to the motor nameplate power factor.

4| Master / Slave| The output torque is controlled based on the signal from the Master / Slave, whereby 100% input signal level will result in the drive output torque being limited by the value set in P4-07.
5| PID Controller Output| The output torque is controlled based on the output of the PID controller, whereby 100% input signal level will result in the drive output torque being limited by the value set in P4-07.
P4-07| Maximum Motoring Current Limit| P4-08| 500.0| 150.0| %
When operating in Vector Speed or Vector Torque motor control modes (P4-01 = 0 or 1), this parameter defines the maximum torque limit or reference used by the drive in conjunction with P4-06.
When operating in V/F Mode (P4-01 = 2), this parameter defines the maximum output current the drive will provide to the motor before reducing the output frequency to attempt to limit the current.
P4-08| Minimum Motoring Torque Limit| P4-08| 500.0| 150.0| %
Active only in Vector Speed or Vector Torque motor control modes (P4-01 = 0 or 1). Sets a minimum torque limit, whereby the when the drive is enabled, it will always attempt to maintain this torque on the motor at all times whilst operating.
NOTE This parameter should be used with extreme care, as the drive output frequency will increase to achieve the torque level, and may exceed the selected speed reference.
P4-09| Generator Mode Max. Torque Limit (Maximum Regenerative Torque)| 0.0| 200.0| 100.0| %
Active only in Vector Speed or Vector Torque motor control modes (P4-01 = 0 or 1). Sets the maximum regenerating torque allowed by the drive.
P4-10| V/F Characteristic Adjustment Frequency| 0.0| P1-09| 0.0| Hz
When operating in V/F mode (P4-01 = 2), this parameter in conjunction with P4-11 sets a frequency point at which the voltage set in P4-11 is applied to the motor. Care must be taken to avoid overheating and damaging the motor when using this feature.
P4-11| V/F Characteristic Adjustment Voltage| 0| P1-07| 0| V
Used in conjunction with parameter P4-10.
P4-12| Thermal Overload Value Retention| 0| 1| 0| –
0| Disabled|
1| Enabled| All drives feature electronic thermal overload protection for the connected motor, designed to protect the motor against damage. An internal overload accumulator monitors the motor output current over time, and will trip the drive if the usage exceeds the thermal limit. When P4-12 is disabled, removing the power supply from the drive and re- applying will reset the value of the accumulator. When P4-12 is enabled, the value is retained during power off.
P4-13| Output Phase Sequence| 0| 1| 0| –

Serial Communications

9.1. RJ45 Connector Pin Assignment
The P2 drive has an RJ45 connector on the front of the control panel. This connector allows the user to set up a drive network via a
wired connection. The connector contains multiple interfaces for different communication protocols:

• Optibus Protocol – Used for PC and peripheral connection only
• Modbus RTU
• CANBus

The Optibus connection is always available, and can be used simultaneously with other interfaces, however only one other interface may be used, e.g. If Modbus RTU is in use, CAN is disabled. If a Fieldbus Option Module (E.g. Profibus) is inserted into the drive, both Modbus and CAN are disabled.
The electrical signal arrangement of the RJ45 connector is shown as follows:

9.2. Modbus RTU Communications
9.2.1. Modbus Telegram Structure
The P2 drive supports Master / Slave Modbus RTU communications, using the 03 Read Holding Registers and 06 Write Single Holding Register commands. Many Master devices treat the first Register address as Register 0; therefore it may be necessary to convert the Register Numbers detail in section 0 by subtracting 1 to obtain the correct Register address. The telegram structure is as follows:

Command 03 – Read Holding Registers

Master Telegram| Length| | Slave Response| Length
Slave Address| 1| Byte| Slave Address| 1| Byte
Function Code (03)| 1| Byte| Function Code (03)| 1| Byte
1st Register Address| 2| Bytes| Byte Count| 1| Byte
No. Of Registers| 2| Bytes| 1st Register Value| 2| Bytes
CRC Checksum| 2| Bytes| 2nd Register Value| 2| Bytes

9.2.2. Modbus Control & Monitoring Registers
The following is a list of accessible Modbus Registers available in the P2 drive.

• When Modbus RTU is configured as the Fieldbus option, all of the listed registers can be accessed.

• Registers 1 and 2 can be used to control the drive providing that Modbus RTU is selected as the primary command source (P1-12 = 4) and no Fieldbus Option Module is installed in the drive Option Slot.

• Register 3 can be used to control the output torque level providing that:
  o The drive is operating in Vector Speed or Vector Torque motor control modes (P4-01 = 1 or 2).
  o The torque controller reference / limit is set for ‘Fieldbus’ (P4-06 = 3).

• Register 4 can be used to control the acceleration and deceleration rate of the drive providing that Fieldbus Ramp Control is enabled (P5-07 = 1).

• Registers 6 to 24 can be read regardless of the setting of P1-12.

Register Number| Upper Byte| Lower Byte| Read Write| Notes
---|---|---|---|---
1| Command Control Word| R/W| Command control word used to control the drive when operating with Modbus RTU. The Control Word bit functions are as follows: Bit 0 : Run/Stop command. Set to 1 to enable the drive. Set to 0 to stop the drive. Bit 1 : Fast stop request. Set to 1 to enable drive to stop with 2nd deceleration ramp. Bit 2 : Reset request. Set to 1 in order to reset any active faults or trips on the drive. This bit must be reset to zero once the fault has been cleared.
Bit 3 : Coast stop request. Set to 1 to issue a coast stop command.
2| Command Speed Reference| R/W| Setpoint must be sent to the drive in Hz to one decimal place, e.g. 500 = 50.0Hz.
3| Command Torque Reference| R/W| Setpoint must be sent to the drive in % to one decimal place, e.g. 2000 = 200.0%.
4| Command Ramp times| R/W| This register specifies the drive acceleration and deceleration ramp times used when Fieldbus Ramp Control is selected (P5-08 =

1. irrespective of the setting of P1-12. The input data range is from 0 to 60000 (0.00s to 600.00s).
   6| Error code| Drive status| R| This register contains 2 bytes.
   The Lower Byte contains an 8 bit drive status word as follows:
   Bit 0 : 0 = Drive Disabled (Stopped), 1 = Drive Enabled (Running). Bit 1 : 0 = Drive Healthy, 1 = Drive Tripped.
   Bit 2 : No Function.
   Bit 3 : Drive Ready, 1 = Drive Inhibit.
   Bit 4 : Maintenance Time Not Reached, 1 = Maintenance Time Reached. Bit 5 : 0 = Not In Standby (Sleep), 1 = Standby (Sleep) mode active.
   Bit 6 : No function.
   Bit 7 : 0 = Normal condition, 1 = Low or High Load condition detected.
   The Upper Byte will contain the relevant fault number in the event of a drive trip.
   Refer to section 11.1. Fault Messages for a list of fault codes and diagnostic information.
   Bit 8 : No Function.
   The Upper Byte will contain the relevant fault number in the event of a drive trip.
   Refer to section 11.1. Fault Messages for a list of fault codes and diagnostic information.
   7| Output Frequency| R| Output frequency of the drive to one decimal place, e.g.123 = 12.3 Hz.
   8| Output Current| R| Output current of the drive to one decimal place, e.g.105 = 10.5 Amps.
   9| Output Torque| R| Motor output torque level to one decimal place, e.g. 474 = 47.4 %.
   10| Output Power| R| Output power of the drive to two decimal places, e.g.1100 = 11.00 kW.
   11| Digital Input Status| R| Represents the status of the drive inputs where Bit 0 = Digital Input 1 etc.
   20| Analog 1 Level| R| Analog Input 1 Applied Signal level in % to one decimal place, e.g. 1000 = 100.0%.
   21| Analog 2 Level| R| Analog Input 2 Applied Signal level in % to one decimal place, e.g. 1000 = 100.0%.
   22| Pre Ramp Speed Reference| R| Internal drive frequency setpoint.
   23| DC bus voltages| R| Measured DC Bus Voltage in Volts.
   24| Drive temperature| R| Measured Heatsink Temperature in °C.

9.2.3. Modbus Parameter Access
All User Adjustable parameters (Groups 1 to 5) are accessible by Modbus, except those that would directly affect the Modbus communications, e.g.

• P5-01 Drive Fieldbus Address
• P5-03 Modbus RTU Baud Rate
• P5-04 Modbus RTU Data Format.

All parameter values can be read from the drive and written to, depending on the operating mode of the drive – some parameters cannot be changed whilst the drive is enabled for example.
When accessing a drive parameter via Modbus, the Register number for the parameter is the same as the parameter number. Some parameters are internally scaled, for further information refer to the P2 drive Modbus Register Map Application Note, or  Advanced User Guide.
E.g. Parameter P1-03 = Modbus Holding Register 103.
Since Modbus RTU supports sixteen bit integer values only, and the parameter is adjustable to one decimal place, the register value will be multiplied by a factor of ten, E.g. Read Value of P1-03 = 50, therefore this is 5.0 seconds.

9.3. CAN Open Communication
9.3.1. Overview
The CANopen communication profile in the P2 drive is implemented according to the specification DS301 version 4.02 of CAN in automation (www.can- cia.de). Specific device profiles such as DS402 are not supported.
9.3.2. Basic Operation Setup
The CANopen communication function is enabled by default after power up however in order to use any control functions through CANopen, Parameter P1-12 must be set to 6.
The CAN communication baud rate can is selected by parameter P5-02. Available baud rates are 125kbps, 250kbps, 500kbps, 1Mbps. Default settings is 500kbps.
The Node ID is set up through drive address parameter P5-01 with a default value of 1.
9.3.3. COB ID and Functions
The P2 drive provides the following default COB-ID and functions:

Table 1 : Messages and COB-IDs

Type| COB-ID| Function
NMT| 000h| Network management.
Sync| 080h| Synchronous message.
COB-ID can be configured to other value.
Emergency| 080h + Node address| Emergency message.
COB-ID can be configured to other value.
PDO1 (TX)| 180h + Node address| Process data object.
PDO1 is pre-mapped and enabled by default. PDO2 is pre-mapped and disabled by default.
Transmission mode, COB-ID and mapping can be configured.
PDO1 (RX)| 200h + Node address
PDO2 (TX)| 280h + Node address
PDO2 (RX)| 300h + Node address
SDO (TX)| 580h + Node address| SDO channel can be used for drive parameter access.
SDO (RX)| 600h + Node address

NOTE

1. The P2 SDO channel only supports expedited transmission.

2. The P2 can only support up to 2 Process Data Objects (PDO). All PDOs are pre-mapped, however PDO2 is disabled by default.
   Table 2 gives the default PDO mapping information.

3. Customer configuration (mapping) will NOT be saved during power down. This means that the CANopen configuration will restore to its default condition each time the drive is powered up.

NOTE

• Ratings shown above apply to 40°C Ambient temperature. For derating information, refer to section 10.4.1. Derating for Ambient Temperature.
• The maximum motor cable length stated applies to using a shielded motor cable. When using an unshielded cable, the maximum cable length limit may be increased by 50%. When using the Bardac recommended output choke, the maximum cable length may be increased by 100%.
• The PWM output switching from any inverter when used with a long motor cable length can cause an increase in the voltage at the motor terminals, depending on the motor cable length and inductance. The rise time and peak voltage can affect the service life of the motor. Bardac recommends using an output choke for motor cable lengths of 50m or more to ensure good motor service life.
• For UL compliant installation, use Copper wire with a minimum insulation temperature rating of 70°C, UL Class CC or Class J Fuses.

10.3. Additional Information for UL Approved Installations
The P2 is designed to meet the UL requirements. In order to ensure full compliance, the following must be fully observed.

Input Power Supply Requirements

Supply Voltage| 200 – 240 RMS Volts for 230 Volt rated units, + /- 10% variation allowed. 240 Volt RMS Maximum.
380 – 480 Volts for 400 Volt rated units, + / – 10% variation allowed, Maximum 500 Volts RMS.
500 – 600 Volts for 600 Volt rated units, + / – 10% variation allowed, Maximum 600 Volts RMS.
Imbalance| Maximum 3% voltage variation between phase – phase voltages allowed.
All P2 units have phase imbalance monitoring. A phase imbalance of > 3% will result in the drive tripping. For input supplies which have supply imbalance greater than 3% (typically the Indian sub- continent & parts of Asia Pacific including China) Bardac recommends the installation of input line reactors. Alternatively, the drives can be operated as a single phase supply drive with 50% derating.
Frequency| 50 – 60Hz + / – 5% Variation.
Short Circuit Capacity| Voltage Rating| Min kW (HP)| Max kW (HP)| Maximum supply short-circuit current
All| All| All| 100kA rms (AC)
All the drives in the above table are suitable for use on a circuit capable of delivering not more than the above specified maximum short-circuit Amperes symmetrical with the specified maximum supply voltage.
Incoming power supply connection must be according to section 4.3. Incoming Power Connection.
All P2 units are intended for indoor installation within controlled environments which meet the condition limits shown in section 10.1. Environmental.
Branch circuit protection must be installed according to the relevant national codes. Fuse ratings and types are shown in section 10.2. Input/ Output Power and Current Ratings.
Suitable Power and motor cables should be selected according to the data shown in section 10.2. Input/Output Power and Current Ratings.
Power cable connections and tightening torques are shown in section 3.4. Installation Following a Period of Storage.
The P2 provides motor overload protection in accordance with the National Electrical Code (US).
Where a motor thermistor is not fitted, or not utilised, Thermal Overload Memory Retention must be enabled by setting P4-12 = 1.
Where a motor thermistor is fitted and connected to the drive, connection must be carried out according to the information shown in section
4.7. Motor Terminal Box Connections.

10.4. Derating Information
Derating of the drive maximum continuous output current capacity is require when:

• Operating at ambient temperature in excess of 40°C / 104°F for enclosed drives (non UL approved).
• Operating at Altitude in excess of 1000m/ 3281 ft.
• Operation with Effective Switching Frequency higher than the minimum setting.
  The following derating factors should be applied when operating drives outside of these conditions.

10.4.1. Derating for Ambient Temperature

Enclosure Type| Maximum Temperature Without Derating (UL Approved)| Derate by| Maximum Permissible Operating Ambient Temperature with Derating (Non UL Approved)
---|---|---|---
IP20| 50°C / 122°F| N/A| 50°C
IP55| 40°C / 104°F| 1.5% per °C (1.8°F)| 50°C
IP66| 40°C / 104°F| 2.5% per °C (1.8°F)| 50°C

10.4.2. Derating for Altitude

Enclosure Type| Maximum Altitude Without Derating| Derate by| Maximum Permssable (UL Approved)| Maximum Permssable (Non-UL Approved)
---|---|---|---|---
IP20| 1000m / 3281ft| 1% per 100m / 328 ft| 2000m / 6562 ft| 4000m / 13123 ft
IP55| 1000m / 3281ft| 1% per 100m / 328 ft| 2000m / 6562 ft| 4000m / 13123 ft
IP66| 1000m / 3281ft| 1% per 100m / 328 ft| 2000m / 6562 ft| 4000m / 13123 ft

10.4.3. Derating for Swicthing Frequency

10.4.4. Example of applying Derating Factors
A 4kW, IP66 drive is to be used at an altitude of 2000 metres above sea level, with 12kHz switching frequency and 45°C ambient temperature.
From the table above, we can see that the rated current of the drive is 9.5 Amps at 40°C,
Firstly, apply the switching frequency derating, 12kHz, 25% derating
9.5 Amps x 75% = 7.1 Amps
Now, apply the derating for higher ambient temperature, 2.5% per °C above 40°C = 5 x 2.5% = 12.5%
7.1 Amps x 87.5% = 6.2 Amps
Now apply the derating for altitude above 1000 metres, 1% per 100m above 1000m = 10 x 1% = 10%
7.9 Amps x 90% = 5.5 Amps continuous current available.
If the required motor current exceeds this level, it will be necessary to either:

• Reduce the switching frequency selected.
• Use a higher power rated drive and repeat the calculation to ensure sufficient output current is available.

10.5. Internal EMC Filter and Varistors – Disconnection Procedure
10.5.1. IP20 Drive Models
All P2 drive models provide a simple method to disconnect the internal EMC filter and surge protection varistors by fully removing the screws shown below. This should only be carried out where necessary, for example in cases such as IT or ungrounded  supplies, where the phase to ground voltage can exceed the phase to phase voltage.
The EMC filter disconnect screw is labelled “EMC“.
The surge protection varistors disconnect screw is clearly labelled “VAR”.

Frame Sizes 2 & 3
The EMC Filter and Varistor disconnect screws are located on the left side of the product when viewed from the front. Remove both screws completely

Frame Sizes 4
Frame Size 4 units have EMC Filter disconnection points only located on the front face of the unit as shown.

Frame Size 5
Frame Size 5 units have EMC Filter disconnection points only located on the front face of the unit as shown.

10.5.2. IP55 & IP66 Models
These models require disassembly in order to disconnect the EMC filter. Disconnection should be carried out only by Bardac Approved Service Partners.

Troubleshooting

11.1. Fault Messages

Fault Code| No.| OLED Message Description| Corrective Action
---|---|---|---
| 00| No Fault| Displayed in P0-13 if no faults are recorded in the log.
| 01| Brake channel over current| Ensure the connected brake resistor is above the minimum permissible level for the drive – refer to the ratings shown in section 10.2. Input/Output Power and Current Ratings.
Check the brake resistor and wiring for possible short circuits.
| 02| Brake resistor overload| The drive software has determined that the brake resistor is overloaded, and trips to protect the resistor. Always ensure the brake resistor is being operated within its designed parameter before making any parameter or system changes.
To reduce the load on the resistor, increase deceleration the time, reduce the load inertia or add further brake resistors in parallel, observing the minimum resistance value for the drive in use.
| 03| Over current trip| Fault Occurs on Drive Enable
Check the motor and motor connection cable for phase – phase and phase – earth short circuits. Check the load mechanically for a jam, blockage or stalled condition.
Ensure the motor nameplate parameters are correctly entered, P1-07, P1-08, P1-09.
If operating in Vector mode (P4-01 – 0 or 1), also check the motor power factor in P4-05 and ensure an autotune has been successfully completed for the connected motor.
Reduced the Boost voltage setting in P1-11. Increase the ramp up time in P1-03.
If the connected motor has a holding brake, ensure the brake is correctly connected and controlled, and is releasing correctly.
Fault Occurs When Running
If operating in Vector mode (P4-01 – 0 or 1), reduce the speed loop gain in P4-03.
| 04| Drive has tripped on overload after delivering >100% of value in P1-08 for a period of time.| Check to see when the decimal points are fiashing (drive in overload) and either increase acceleration rate or reduce the load.
Check motor cable length is within the limit specified for the relevant drive in section 10.2. Ensure the motor nameplate parameters are correctly entered in P1-07, P1-08, and P1-09.
If operating in Vector mode (P4-01 – 0 or 1), also check the motor power factor in P4-05 and ensure an autotune has been successfully completed for the connected motor.
Check the load mechanically to ensure it is free, and that no jams, blockages or other mechanical faults exist.
| 05| Hardware Over Current| Check the wiring to motor and the motor for phase to phase and phase to earth short circuits. Disconnect the motor and motor cable and retest. If the drive trips with no motor connected, it must be replaced and the system fully checked and retested before a replacement unit is installed.
| 06| Over voltage on DC bus| The value of the DC Bus Voltage can be displayed in P0-20.
A historical log is stored at 256ms intervals prior to a trip in parameter P0-36.
This fault is generally caused by excessive regenerative energy being transferred from the load back to the drive. When a high inertia or over hauling type load is connected.
If the fault occurs on stopping or during deceleration, increase the deceleration ramp time P1-04 or connect a suitable brake resistor to the drive.
If operating in Vector Mode, reduce the speed loop gain P4-03.
If operating in PID control, ensure that ramps are active by reducing P3-11.
| 07| Under voltage on DC bus| This occurs routinely when power is switched off.
If it occurs during running, check the incoming supply voltage, and all connections into the drive, fuses, contactors etc.
| 08| Heatsink over temperature| The heatsink temperature can be displayed in P0-21.
A historical log is stored at 30 second intervals prior to a trip in parameter P0-38. Check the drive ambient temperature.
Ensure the drive internal cooling fan is operating.
Ensure that the required space around the drive as shown in sections 3.5. Mechanical Dimensions and Weight to 3.9. Guidelines for Mounting (IP66 Units) has been observed, and that the cooling airfiow path to and from the drive is not restricted.
Reduce the effective switching frequency setting in parameter P2-24. Reduce the load on the motor / drive.
| 09| Under temperature| Trip occurs when ambient temperature is less than -10°C. The temperature must be raised over
-10°C in order to start the drive.
| 10| Factory Default parameters have been loaded| Press STOP key, the drive is now ready to be configured for the required application.
| 11| External trip| E-trip requested on control input terminals. Some settings of P1-13 require a normally closed contact to provide an external means of tripping the drive in the event that an external device develops a fault. If a motor thermistor is connected check if the motor is too hot.
Fault Code| No.| OLED Message Description| Corrective Action
---|---|---|---
| 12| Communications Fault| Communications lost with PC or remote keypad. Check the cables and connections to external devices.
| 13| Excessive DC ripple| The DC Bus Ripple Voltage level can be displayed in parameter P0-16.
A historical log is stored at 20ms intervals prior to a trip in parameter P0-37.
Check all three supply phases are present and within the 3% supply voltage level imbalance tolerance.
Reduce the motor load.

Try again. If problem recurs, refer to your Bardac Authorised Distributor.
| 20| User Parameter Default| User Parameter defaults have been loaded. Press the Stop key.
| 21| Motor PTC Over Temperature| The connected motor PTC device has caused the drive to trip.
| 22| Cooling Fan Fault| Check and if necessary, replace the drive internal cooling fan.
| 23| Ambient Temperature High| The measured temperature around the drive is above the operating limit of the drive. Ensure the drive internal cooling fan is operating.
Ensure that the required space around the drive as shown in sections 3.5. Mechanical Dimensions and Weight to 3.9. Guidelines for Mounting (IP66 Units) has been observed, and that the cooling airfiow path to and from the drive is not restricted.
Increase the cooling airfiow to the drive.
Reduce the effective switching frequency setting in parameter P2-24. Reduce the load on the motor / drive.
| 24| Maximum Torque Limit Exceeded| The output torque limit has exceeded the drive capacity or trip threshold. Reduce the motor load, or increase the acceleration time.
| 25| Output Torque Too Low| Active only when hoist brake control is enabled P2-18 = 8. The torque developed prior to releasing the motor holding brake is below the preset threshold. Contact your local Bardac Sales Partner for further information on using the P2 drive in hoist applications.
