Commissioning Notes

Always read chapter Commissioning in the product’s User’s Manual
before you begin.

• Set motor parameters according to the rating plate of the motor
  and the parameters for the pump/fan/compressor.

• If you want to test the Autochange function, set the Interval
  Time (ID1501) to 0. Autochange will then occur after 5 minutes of
  running. Remember to set a correct value after testing.

Drive Status Indication

On monitoring page V1.23, you can find the Drive Status. This
value gives you information about the current status of the
drive.

• 0 = OFF: The automatics are not enabled via DIN1.

• 2 = Stand-by: The drive is activated but waiting for permission
  to start (not used as leading drive) either via a start command
  from the other drives (MMPFC) or depending on the actual value
  (ALC).

• 3 = Regulating: The drive is working as the leading drive in
  the system.

• 4 = Nominal production: The drive has locked itself to nominal
  production frequency, (ID102 or ID1513). The regulation is handled
  by another drive.

• NOTE: In the MultiFollower PFC application, this status has a
  different meaning: 4 = Following. The regulation is handled by
  another drive, and this drive is following the frequency reference
  of the leading drive.

• 5 = Sleeping: The drive is the leading drive, but the actual
  value (pressure) is so high that the drive has gone into sleep
  status.

On monitoring page V1.24, you can also find a value called
Status Word. In case of application malfunctioning, this value will
be needed by Vacon service personnel.

Pressure/Level Feedback

Individual sensor for each drive gives a redundant system
(preferable).

Figure 1 shows different options to connect the pressure or
level transmitter.

Function / Terminal Programming Methods

There are two methods for programming the input and output
signals for the NX drives. The first method is called the FTT or
Function To Terminal, the other method is called TTF or Terminal To
Function.

Product Usage Instructions

Commissioning

Before starting the commissioning process, make sure to read the
Commissioning chapter in the product’s User’s Manual.

Follow these steps to commission the AC drive:

1. Set motor parameters according to the rating plate of the motor
   and the parameters for the pump/fan/compressor.

2. If you want to test the Autochange function, set the Interval
   Time (ID1501) to 0. Autochange will then occur after 5 minutes of
   running. Remember to set a correct value after testing.

Drive Status Indication

The Drive Status provides information about the current status
of the drive. To check the Drive Status:

1. Go to monitoring page V1.23.
2. Look for the value displayed for Drive Status.
3. Refer to the following codes for interpretation:

• 0 = OFF: The automatics are not enabled via DIN1.

• 2 = Stand-by: The drive is activated but waiting for permission
  to start (not used as leading drive) either via a start command
  from the other drives (MMPFC) or depending on the actual value
  (ALC).

• 3 = Regulating: The drive is working as the leading drive in
  the system.

• 4 = Nominal production: The drive has locked itself to nominal
  production frequency, (ID102 or ID1513). The regulation is handled
  by another drive.

• NOTE: In the MultiFollower PFC application, this status has a
  different meaning: 4 = Following. The regulation is handled by
  another drive, and this drive is following the frequency reference
  of the leading drive.

• 5 = Sleeping: The drive is the leading drive, but the actual
  value (pressure) is so high that the drive has gone into sleep
  status.

On monitoring page V1.24, you can find a value called Status
Word. This value may be needed by Vacon service personnel in case
of application malfunctioning.

Pressure/Level Feedback

It is recommended to use an individual sensor for each drive to
create a redundant system. Follow the instructions below to connect
the pressure or level transmitter:

0.1 Commissioning notes Always read chapter Commissioning in the product’s User’s Manual before you begin.
Set motor parameters according to the rating plate of the motor, and the parameters for the pump/fan/compressor.
0.1.1 Using MultiMaster PFC or Advanced Level Control applications It is important that the Own ID (ID1500) is set, and that all drives in the same chain have a unique number. Also the parameter Number of Drives (ID1502) has to be correct (MMPFC only) In order to ensure the proper functioning of the communication, the diode and the other connections (See Figure 9) have to be made correctly. The CMA and CMB have to be isolated from ground. This is done by setting the jumpers of block X3 on the OPT-A1 board as shown in Figure 10.
If you want to test the Autochange function, set the Interval Time (ID1501) to 0. Autochange will then occur after 5 min running. Remember to set a correct value after testing.
0.2 Drive status indication On monitoring page V1.23 you can find the Drive Status. This value gives you information about the current status of the drive.
0 = OFF
The automatics are not enabled via DIN1.
1 = Communication line error The communication between the drives has been down for more than 10 seconds. Check connections, diodes (also polarity), check that the CMA and CMB are open (See Figure 10 below). This error cannot be reset through the Reset command. To reset, turn DIN1 OFF and back ON in one or several drives. This error may also appear if the grounding between the drives is insufficient. During tests of the system without complete cabling, connect the GND’s (pin 13) of the drives with a wire.
2 = Stand-by The drive is activated but waiting for permission to start (not used as leading drive) either via a start command from the other drives (MMPFC) or depending of the actual value (ALC).

3 = Regulating The drive is working as the leading drive in the system.
4 = Nominal production The drive has locked itself to nominal production frequency, (ID102 or ID1513). The regulation is handled by another drive.
NOTE: In the MultiFollower PFC application this status has a different meaning: 4 = Following The regulation is handled by another drive and this drive is following the frequency reference of the leading drive.
5 = Sleeping The drive is the leading drive, but the actual value (pressure) is so high so the drive has gone into sleep status.
On monitoring page V1.24 you can also find a value called Status Word. In case of application malfunctioning, this value will be needed by Vacon service personnel.

0.4 Function / terminal programming methods
There are two methods for programming the input and output signals for the NX drives. The first method is called the FTT or Function To Terminal, the other method is called TTF or Terminal To Function.

In FTT, the terminal appears as a parameter and the user defines which function he wants to be activated with the specific terminal. This is the traditional way of I/O programming. See Figure 2.
In the figure, the function Run Enable is activated via DIN3.

P2.2.2 DIN3 function: 0= Not Used 1= Ext.Fault (cc) 2= Ext.Fault (oc) 3= Run Enable 4= Acc/Dec….
Figure 2. FTT programming method

In TTF, the different functions appear as parameters and the user defines to which terminal he wants to connect the function. This method allows a flexible use of additional I/O boards. See Figure 3.
P2.3.29.1 Ready = A.1 P2.3.29.2 Run = 0.2 P2.3.29.3 Fault = B.1 P2.3.29.4 Fault, inv. = 0.1
Figure 3. TTF programming method
The examples in Figure 3 presuppose the connection of option boards OPT-A1 and OPT-A2:
‘Ready’ function is connected to slot A, 1st digital or relay output (DO1), ‘Run’ function is connected to a virtual board with value TRUE, i.e. active ‘Fault’ function is connected to slot B, 1st digital or relay output (RO1) ‘Fault inverted’ function is connected to a virtual board with value FALSE, i.e. NOT active
The first letter represents the slot (0 = virtual slot) and the number is the index number of the terminal. Depending on the option board, there can be several (or no) inputs and/or outputs available. If there are both inputs and outputs on the same board the first input is named A.1. Note that the first output is also named A.1.
NOTE! With this method, is it possible to have several signals connected to one hardware input, but only one signal can control one hardware output.

Figure 4. Capacity of an interface board

Each option board can have up to 10 inputs and/or outputs of each type, but all 10 are not necessarily used on every board (the amount of terminals causes limitations).

Figure 4 describes the standard option board.

Available inputs and outputs on Vacon basic option boards
OPT-A1 in slot A: · two analogue inputs available, named A.1 and A.2 when programming · six digital inputs, named A.1 to A.6 when programming · one analogue output, named A.1 when programming · one digital output, named A.1 when programming

OPT-A2 in slot B: · two digital outputs available, named B.1 and B.2 when programming

Note: In spite of the terminal type (input/output, digital/analogue), the naming principle is the same for all terminals on the same board. Therefore, the first analogue input on board OPT-A1 is named A.1, but the first digital output on board OPT-A1 is also named A.1.

Functions that are not used are programmed to the virtual board in slot 0. Depending of the needed value or level the number is set to 1, 2 or 3.

MultiMaster PFC application

2. MULTIMASTER PFC APPLICATION
2.1 Brief description of MultiMaster PFC application
With the MultiMaster PFC application, you can build a system where up to 3 drives handle the regulation. The internal PID controller regulates the drives. The drives are operating in a chained control where one of them is always the leading drive. This way they can together control a system with several devices in parallel.
When you have the application package loaded in your Vacon drive you can select the MultiMaster PFC application in system menu, M6 with parameter S6.2.
2.2 Functionality
The application is designed to achieve an even wear of the pumps connected to the motors/ drives by regularly changing the regulating order of the drives. The application supports the maximum of 3 pumps, fans or compressors to work in parallel. One drive is leading and regulating (PID) while the others are either stand-by or running at the speed that produces the nominal flow in the system.
Connections to/ from and between the drives are easily made. The drive is connected directly to its own motor/ pump. There is neither need for additional contactors nor any soft starting devices. An ordinary pair cable is used for the communications between drives.

2.3 Chained control and autochange
When the leading drive notices a demand for more capacity, but cannot produce this by itself, it will send a request for NEXT START on the communication line. It will lock itself at nominal producing speed and the next drive will start controlling. When the leading drive notices that there is too much capacity (running at min. producing frequency) AND there are units running at nominal producing speed, then it will put itself to Stand-by mode and the drive running at nominal producing speed will start controlling. If there are several drives running at nominal producing speed, the one with highest priority will start to regulate. If there are NO drives running at nominal producing speed when the drive notices the overcapacity, the drive will go into Sleeping mode.

The Vacon drives in the system will automatically alternate operating as the leading drive to equalize the wear of the devices in the system. The drive is counting time for the autochange event when is running. The time to run before the autochange shall occur can be set by the user. When the drive reaches the set time, it will stop regulating and then slowly ramp down and stop. The other drives will notice that the drive is stopping for the autochange event and the next drive will take up the control.

When all drives in the installation have performed their leading role the timers of all drives are reset. The “reset” command does not necessarily set the counters to zero, but the counter value is decreased by the autochange value set by the user. (Default value is 48h)

Examples: Autochange time: Running hours: Running hours after reset:

48h 64h 64-48=16h

The counter value can increase over 48h (autochange value) if this drive has been running while the others have been in the leading role. This way the running times of the drives are equalized.

NOTE! All digital inputs are used with negative logic (0V is active). Jumper X3 has to be connected so that CMA and CMB are isolated from ground, i.e. OPEN. See Figure 10 below.

Digital inputs DIN3, DIN4, DIN5 are freely programmable. So is the digital output DO1 which, together with the digital input DIN6, is reserved for the communication between drives.

Advanced Level Control application

vacon · 37

3. ADVANCED LEVEL CONTROL APPLICATION
3.1 Brief description
With the Advanced Level Control application you can build a system where up to 3 drives control the pumping from a storage tank. One frequency converter controls the pump that is the leading pump and handles the main regulation and the other ones are started if the liquid level in the tank is close to reaching the edge of the tank. This system guarantees that the flow from the tank remains as steady as possible. In case of excessive amount of water in the tank for the leading pump to handle and the buffering capacity of the tank is not enough the auxiliary pumps will start before the tank flows over.

When you have the application package loaded in your Vacon drive you can select the Advanced Level Control application in system menu, M6 with parameter S6.2.

3.2 Functionality
The application is designed in order to achieve an even wear of the pumps connected to the motors/drives by regularly changing the leading drive. The application supports the maximum of 3 pumps to work in parallel. When the drive is activated via DIN1 the system decides, on the basis of the ID numbers of the drives, which drive is the leading drive. The leading one is regulating, either as PID or linearly between two points, while the auxiliary drives are either stand-by or, in case the start level is exceeded, started. The start order of the auxiliary drives is also based on the ID number.

Connections to/ from and between the drives are easily made.The drive is connected directly to its own motor/pump. There is neither need for additional contactors nor any soft starting devices. An ordinary pair cable is used for the communications between drives.

Advanced Level Control application

3.3 Level control and autochange
The leading drive runs either as a PID regulator or linearly between the set upper and lower limits. In case of great amount of incoming water, the leading drive will run at full speed and the tank will use its buffer capacity. If the level in the tank continues to rise the auxiliary pumps will start when the set level is reached, (parameter ID1566, Aux1/2 Upper Level).

The auxiliary pumps can either run at nominal production speed between the upper and lower limits or run linearly between the limits (default). It is also selectable if the auxiliary drives start from the lower or higher (default) limit when in Linear mode. If the auxiliary drives are running in Nominal production mode it will always start at a higher level.

The Vacon drives in the system will automatically change the leading drive to equalize the wear of the devices in the system. The drive is counting time for the autochange event when it is running. The time to run before the autochange occurs can be set by the user. When the drive reaches the set time, it will stop regulating and then slowly ramp down and stop. The other drives will notice that the drive is stopping for the autochange event and the next drive will become the leading one.

When all drives in the installation have performed their leading role the timers of all drives are reset. The “reset” command does not necessarily set the counters to zero, but the counter value is decreased by the autochange value set by the user. (Default value is 48h)

Examples: Autochange time: Running hours: Running hours after reset:

48h 64h 64-48=16h

The counter value can increase over 48h (autochange value) if this drive has been running while the others have been in the leading role. This way the running times of the drives are equalized.

MultiFollower PFC application

4. MULTIFOLLOWER PFC APPLICATION
4.1 Brief description
With the MultiFollower PFC application you can build a system where up to 3 drives handle the regulation. The internal PID regulator controls the drives that are working in a chained control where one of them is always the regulating drive. This way they can together control a system with several devices in parallel.
When you have the application package loaded in your Vacon drive you can select the MultiFollower PFC application in system menu, M6 with parameter S6.2.
4.2 Functionality
The application is designed to achieve an even wear of the pumps connected to the motors/ drives by regularly changing the regulating order to of the drives. The application supports the maximum of 3 pumps, fans or compressors to work in parallel. One drive is leading and regulating (PID) while the others are either stand-by or, if working as auxiliary drives, following the same speed that the leading one is running at.
Connections to/ from and between the drives are made easily. The drive is connected directly to its own motor/ pump. There is neither need for additional contactors nor any soft starting devices. An ordinary shielded twisted pair cable is used for the communications between drives, and for the shared frequency reference transmission.

4.3 Chained regulation and autochange
When the regulating drive notices a demand for more capacity, but cannot produce this by itself, it will send a request for NEXT START to the communication line. When the next drive starts to regulate it will send the frequency reference to the analogue output. The drive(s) that is (are) working as an auxiliary drive will read this value from its analogue input 1, and it will start to run at the same speed as the regulating drive. In other words, the auxiliary pump is following the speed reference of the leading drive /pump. When the regulating drive notices that there is too much capacity (running at the minimum producing frequency + 1,5Hz) AND there are auxiliary units connected to the system, it will put itself to Stand-by mode and the auxiliary drive will become the leading drive and start regulating. If there are several drives working as auxiliary drives, the one with the highest priority will start to regulate. If there are NO auxiliary drives available when the drive notices the overcapacity, the drive will go into Sleeping mode.

The Vacon drives in the system will automatically change the leading drive to equalize the wear of the devices in the system. The drive is counting time for the autochange event when it is running. The time to run before the autochange event shall occur can be set by the user. When the drive reaches the set time, it will stop regulating and then slowly ramp down and stop. The other drives will notice that the drive is stopping for the autochange event and the next drive will take up the control.

When all drives in the installation have performed their leading role the timers of all drives are reset. The “reset” command does not necessarily set the counters to zero, but the counter value is decreased by the autochange value set by the user. (Default value is 48h)

Examples: Autochange time: Running hours: Running hours after reset:

48h 64h 64-48=16h

The counter value can increase over 48h (autochange value) if this drive has been running while the others have been in the leading role. This way the running times of the drives are equalized.

4.4 Sharing of frequency reference
The auxiliary drives will follow the frequency reference that the leading drive is using. The leading drive sends out the frequency reference to the analogue output. The activated auxiliary drives will see this on analogue input 1 and follow the leading drive using the same frequency.

234 (2.1.1, 2.1.2)

Defines the frequency limits of the frequency converter. The maximum value for parameters ID101 and ID102 is 320 Hz. The software will automatically check the values of parameters ID316 and ID728 The parameters also defines: ID101 Null producing limit / Min output freq. / Lower change freq. / Sleep freq. ID102 Max producing limit / Max output freq. / Upper change freq. The frequency converter is stopped automatically if the frequency of the drive falls below the Sleep frequency defined with this parameter, for a time greater than that determined by parameter ID1017. During the Stop state, the PID controller switches the frequency converter to Run state when the signal of the actual value either falls below or exceeds the Wake-up level, par. ID1018 (depending on the Wake-up action, par. ID1019)

U/f ration selection

234 (2.6.3)

Linear: 0
Squared: 1

The voltage of the motor changes linearly with the frequency in the constant flux area from 0 Hz to the field weakening point where the nominal voltage is supplied to the motor. Linear U/f ration should be used in constant torque applications. This default setting should be used if there is no special need for another setting. The voltage of the motor changes followiing a squared curve form with the frequency in the area from 0 Hz to the field weakening point where the nominal voltage is also supplied to the motor. The motor runs undermagnetised below the field weakening point and produces less torque and electromechanical noise. Squared U/f ratio can be used in applications where torque demand of the load is proportional to the square of the speed, e.g. in centrifugal fans and pumps.

U/f optimisation (2.13, 2.6.2)

Automatic torque boost

The voltage to the motor changes automatically which makes the motor produce sufficient torque to start and run at low frequencies. The voltage increase depends on the motor type and power. Automatic torque boost can be used in applications where starting torque due to starting friction is high, e.g. in conveyors.

EXAMPLE:

What changes are required to start with load from 0 Hz?

First set the motor nominal values (Parameter group 2.1).

Option 1: Activate the Automatic torque boost.

Description of parameters

Option 2: Programmable U/f curve To get torque you need to set the zero point voltage and midpoint voltage/frequency (in parameter group 2.6) so that the motor takes enough current at low frequencies. First set par. ID108 to Programmable U/f curve (value 2). Increase zero point voltage (ID606) to get enough current at zero speed. Set then the midpoint voltage (ID605) to 1.4142ID606 and midpoint frequency (ID604) to value ID606/100%ID111.

NOTE!

In high torque ­ low speed applications ­ it is likely that the motor will overheat. If the motor has to run a prolonged time under these conditions, special attention must be paid to cooling the motor. Use external cooling for the motor if the temperature tends to rise too high.

132

PID controller D-time

234 (2.1.14)

The parameter ID132 defines the derivation time of the PID controller. If this parameter is set to 1,00 second a change of 10% in the error value during 1.00 s causes the controller output to change by 10.00%. If the parameter value is set to 0.00 s the PID controller will operate as PI controller. See examples below.

Example 1: In order to reduce the error value to zero, with the given values, the frequency converter output behaves as follows:

Given values: Par. 2.1.12, P = 0% Par. 2.1.13, I-time = 1.00 s Par. 2.1.14, D-time = 0.00 s Error value (setpoint ­ process value) = 10.00%

Min freq. = 0 Hz Max freq. = 50 Hz

In this example, the PID controller operates practically as I-controller only.

Description of parameters

According to the given value of parameter 2.1.13 (I-time), the PID output increases by 5 Hz (10% of the difference between the maximum and minimum frequency) every second until the error value is 0.

Min freq. = 0 Hz Max freq. = 50 Hz

As the power is switched on, the system detects the difference between the setpoint and the actual process value and starts to either raise or decrease (in case the error value is negative) the PID output according to the I-time. Once the difference between the setpoint and the process value has been reduced to 0 the output is reduced by the amount corresponding to the value of parameter 2.1.13. In case the error value is negative, the frequency converter reacts reducing the output correspondingly. See Figure 25.

input is active. 2 External fault, opening contact = Fault is shown and motor is stopped when the
input is not active. 3 Run enable, contact open = Motor start disabled and the motor is stopped
contact closed = Motor start enabled

Application 1: 4 Run enable contact open
contact closed

= Motor start enabled = Motor start disabled and the motor is stopped

Applications 2 to 4: 4 Closing contact: Force control place to I/O terminal 5 Closing contact: Force control place to keypad 6 Closing contact: Force control place to fieldbus

When the control place is forced to change the values of Start/Stop, Direction and Reference valid in the respective control place are used (reference according to parameters ID122) Note: The value of par. ID125 (Keypad Control Place) does not change.
