3.2.5 Safety Requirements of Mechanical Installation
WARNING
Pay attention to the requirements that apply to integration and the field mounting kit. Observe the information in the list to avoid serious injury or equipment damage, especially when installing large units.
CAUTION
The adjustable frequency drive is cooled by air circulation. To protect the unit from overheating, it must be ensured that the ambient temperature does not exceed the maximum temperature stated for the adjustable frequency drive, and that the 24-hour average temperature is not exceeded. Locate the maximum temperature and 24hour average in the paragraph Derating for Ambient Temperature. If the ambient temperature is in the range of 113°­131°F [45°­55°C], derating of the adjustable frequency drive will become relevant, see Derating for Ambient Temperature. The service life of the adjustable frequency drive is reduced if derating for ambient temperature is not taken into account.
3.2.6 Field Mounting
For field mounting the IP 21/IP 4X top/,TYPE 1 kits or IP 54/55 units are recommended.
3.2.7 Panel Through Mounting
A Panel Through Mount Kit is available for adjustable frequency drive series VLT HVAC Drive, VLT Aqua Drive and .
In order to increase heatsink cooling and reduce panel depth, the adjustable frequency drive may be mounted in a through panel. Furthermore, the built-in fan can then be removed.
The kit is available for enclosures A5 through C2.
NOTE!
This kit cannot be used with cast front covers. IP21 plastic cover must be used instead.
Information on ordering numbers is found in the Design Guide, section Ordering Numbers. More detailed information is available in the Panel Through Mount Kit instruction, MI.33.HX.YY, where yy=language code.

Table 4.2: Terminal connections

Very long control cables and analog signals may, in rare cases and depending on the installation, result in 50/60 Hz ground loops due to noise from line power supply cables.
If this occurs, break the shield or insert a 100 nF capacitor between shield and chassis.
NOTE!
The common of digital / analog inputs and outputs should be connected to separate common terminals 20, 39, and 55. This will prevent ground current interference among groups. For example, it prevents switching on digital inputs from disturbing analog inputs.
NOTE!
Control cables must be shielded/armored.
4.1.3 Fuses
Branch Circuit Protection In order to protect the installation against electrical and fire hazard, all branch circuits in an installation, switch gear, machines, etc., must be short-circuit and overcurrent protected according to the national/international regulations.

WARNING
Short-circuit protection: The adjustable frequency drive must be protected against short-circuit to avoid electrical or fire hazard. Danfoss recommends using the fuses mentioned below to protect service personnel and equipment in case of an internal failure in the drive. The adjustable frequency drive provides full short-circuit protection in case of a short-circuit on the motor output.
WARNING
Overcurrent protection Provide overload protection to avoid fire hazard due to overheating of the cables in the installation. Overcurrent protection must always be provided in accordance with national regulations. The adjustable frequency drive is equipped with internal overcurrent protection that can be used for upstream overload protection (UL applications excluded). See par. 4-18 Current Limit in the VLT HVAC Drive Programming Guide . Fuses must be designed for protection in a circuit capable of supplying a maximum of 100,000 Arms (symmetrical), 500 V/600 V maximum.

Overcurrent protection If UL/cUL is not to be complied with, Danfoss recommends using the fuses mentioned in the table below, which will ensure compliance with EN50178. In case of malfunction, not following the recommendation may result in unnecessary damage to the adjustable frequency drive.

4.1.11 How to Connect Motor – Introduction
See section General Specifications for correct dimensioning of motor cable cross-section and length.
· Use a shielded/armored motor cable to comply with EMC emission specifications (or install the cable in a metal conduit).
· Keep the motor cable as short as possible to reduce the noise level and leakage currents.
· Connect the motor cable shield/armor to both the decoupling plate of the adjustable frequency drive and to the metal of the motor. (The same applies to both ends of the metal conduit if used instead of a shield.)
· Make the shield connections with the largest possible surface area (by using a cable clamp or an EMC cable connector). This is done by using the supplied installation devices in the adjustable frequency drive.
· Avoid terminating the shield by twisting the ends (pigtails), as this will spoil high frequency shielding effects.
· If it is necessary to break the continuity of the shield to install a motor isolator or motor relay, the continuity must be maintained with the lowest possible HF impedance.
Cable length and cross-section The adjustable frequency drive has been tested with a given length of cable and a given cross-section of that cable. If the cross-section is increased, the cable capacitance – and thus the leakage current – may increase, thereby requiring that the cable length is reduced accordingly.
Switching frequency When adjustable frequency drives are used together with sine wave filters to reduce the acoustic noise from a motor, the switching frequency must be set according to the sine wave filter instructions in par. 14-01 Switching Frequency.
Precautions while using aluminum conductors Aluminum conductors are not recommended for cable crosssections less than 0.054 in2 [35 mm2]. Terminals can accept aluminum conductors, but the conductor surface has to be clean, oxidation must be removed, and the area must be sealed by neutral acid-free Vaseline grease before the conductor is connected.

Furthermore, the terminal screw must be retightened after two days due to the softness of the aluminum. It is crucial to ensure that the connection makes a gas tight joint, otherwise the aluminum surface will oxidize again.
All types of three-phase asynchronous standard motors can be connected to the adjustable frequency drive. Normally, small motors are star-connected (230/400 V, D/Y). Large motors are delta-connected (400/690 V, D/Y). Refer to the motor nameplate for correct connection mode and voltage.

Figure 4.16: Terminals for motor connection

CAUTION
In motors without phase insulation paper or other insulation reinforcement suitable for operation with the voltage supply (such as an adjustable frequency drive), fit a sine-wave filter on the output of the adjustable frequency drive. (Motors that comply with IEC 60034-17 do not require a sine- wave filter).

5.2.3 Automatic Motor Adaptation (AMA)
AMA is an algorithm to measure the electrical motor parameters on a motor at standstill. This means that AMA itself does not supply any torque. AMA is useful when commissioning systems and optimizing the adjustment of the adjustable frequency drive to the applied motor. This feature is particularly used where the default setting does not apply to the connected motor. Par. 1-29 Automatic Motor Adaptation (AMA) allows a choice of complete AMA with determination of all electrical motor parameters or reduced AMA with determination of the stator resistance Rs only. The duration of a total AMA varies from a few minutes on small motors to more than 15 minutes on large motors.
Limitations and preconditions:
· For the AMA to determine the motor parameters optimally, enter the correct motor nameplate data in par. 1-20 Motor Power [kW] to par. 1-28 Motor Rotation Check.
· For the best adjustment of the adjustable frequency drive, carry out AMA on a cold motor. Repeated AMA runs may lead to a heating of the motor, which results in an increase of the stator resistance, Rs. Normally, this is not critical.
· AMA can only be carried out if the rated motor current is minimum 35% of the rated output current of the adjustable frequency drive. AMA can be carried out on up to one oversize motor.
· It is possible to carry out a reduced AMA test with a sine-wave filter installed. Avoid carrying out a complete AMA with a sine-wave filter. If an overall setting is required, remove the sine-wave filter while running a total AMA. After completion of the AMA, reinsert the sine-wave filter.
· If motors are coupled in parallel, use only reduced AMA if any.
· Avoid running a complete AMA when using synchronous motors. If synchronous motors are applied, run a reduced AMA and manually set the extended motor data. The AMA function does not apply to permanent magnet motors.
· The adjustable frequency drive does not produce motor torque during an AMA. During an AMA, it is imperative that the application does not force the motor shaft to run, which is known to happen with, e.g., wind milling in ventilation systems. This disturbs the AMA function.

6.1.1 Three Ways of Operating

The adjustable frequency drive can be operated in three ways:
1. Graphical Local Control Panel (GLCP), see 5.1.2
2. Numeric Local Control Panel (NLCP), see 5.1.3
3. RS-485 serial communication or USB, both for PC connection, see 5.1.4
If the adjustable frequency drive is fitted with a serial communication bus option, please refer to relevant documentation.

6.1.2 How to Operate the GraphicalLCP (GLCP)

The following instructions are valid for the GLCP (LCP 102).

The GLCP is divided into four functional groups:

1. Graphical display with Status lines. 2. Menu keys and LEDs – selecting mode, changing
parameters and switching between display functions. 3. Navigation keys and LEDs (LEDs). 4. Operation keys and LEDs. Graphical display: The LCD display is back lit with a total of 6 alpha-numeric lines. All data is displayed on the LCP which can show up to five operating variables while in [Status] mode.
Display lines:
a. Status line: Status messages displaying icons and graphics.
b. Line 1-2: Operator data lines displaying data and variables defined or chosen by the user. By pressing the [Status] key, up to one extra line can be added.
c. Status line: Status messages displaying text.

The display is divided into 3 sections:
The top section (a) shows the status when in status mode or up to 2 variables when not in status mode and in case of an alarm/warning.
The number of the Active Set-up (selected as the Active Set-up in par. 0-10 Active Set-up) is shown. When programming in another set-up than the Active Set-up, the number of the setup being programmed appears to the right in brackets.
The Middle section (b) shows up to 5 variables with related unit, regardless of status. In the case of an alarm/warning, the warning is shown instead of the variables.

The bottom section (c) always shows the state of the adjustable frequency drive in status mode.

7.1.4 Changing a Text Value

Both the GLCP and NLCP provide access to the main menu mode. Select main menu mode by pressing the [Main Menu] key. Figure 6.2 shows the resulting readout, which appears on the display of the GLCP. Lines 2 through 5 on the display show a list of parameter groups which can be chosen by toggling the up and down buttons.

If the selected parameter is a text value, it can be changed by using the up/down navigation keys. The up key increases the value, and the down key decreases the value. Place the cursor on the value to be saved and press [OK].

Figure 7.9: Display example.

Figure 7.8: Display example.

7.1.5 Changing a Group of Numeric Data Values

Each parameter has a name and number which remain the same regardless of the programming mode. In main menu mode, the parameters are divided into groups. The first digit of the parameter number (from the left) indicates the parameter group number.

If the chosen parameter represents a numeric data value,
change the chosen data value by means of the [] and [] navigation keys as well as the up/down [] [] navigation
keys. Use the ] and [] navigation keys to move the cursor horizontally.

All parameters can be changed in the Main Menu. The configuration of the unit (par. 1-00 Configuration Mode) will determine other parameters available for programming. For example, selecting Closed-loop enables additional parameters related to closed-loop operation. Option cards added to the unit enable additional parameters associated with the option device.

7.1.3 Changing Data

1. Press the [Quick Menu] or [Main Menu] key.

2. Use [] and [] keys to find parameter group to edit. Use the up/down navigation keys to change the data value.

3. Press [OK] key.
4. Use [] and [] keys to find parameter to edit.

The up key increases the data value, while the down key reduces it. Place the cursor on the value to be saved and press [OK].

5. Press [OK] key.

6. Use [] and [] keys to select correct parameter
setting. Or, to move to digits within a number, use
the keys. Cursor indicates digit selected to change.
[] key increases the value, [] key decreases the
value.

7. Press the [Cancel] key to disregard the change, or press the [OK] key to accept the change and enter the new setting.

Option:

Function:

[0] * Openloop

Motor speed is determined by applying a speed reference or by setting desired speed when in Hand Mode. Open-loop is also used if the adjustable frequency drive is part of a closed-loop control system based on an external PID controller providing a speed reference signal as output.

[3] Closed- Motor speed will be determined by a reference

loop

from the built-in PID controller varying the motor

speed as part of a closed-loop control process

(e.g., constant pressure or flow). The PID controller

must be configured in par. 20-** or via the

function set-ups accessed by pressing the [Quick

Menu] button.

NOTE!
When set for closed-loop, the commands reversing and
start reversing will not reverse the direction of the
motor.

Variable Torque [1]: For speed control of centrifugal pumps and fans. Also to be used when controlling more than one motor from the same adjustable frequency drive (e.g., multiple condenser fans or cooling tower fans). Provides a voltage which is optimized for a squared torque load characteristic of the motor.

the voltage exactly to the current load situation,

thereby reducing energy consumption and

audible noise from the motor. To obtain optimal

performance, the motor power factor cos phi

must be set correctly. This value is set in

par. 14-43 Motor Cos-Phi. The parameter has a

default value which is automatically adjusted

when the motor data is programmed. These

settings will typically ensure optimum motor

voltage but if the motor power factor cos phi

requires tuning, an AMA function can be carried

out using par. 1-29 Automatic Motor Adaptation

(AMA). It is very rarely necessary to adjust the

motor power factor parameter manually.
