Use the Frost protection function to protect the pump from frost damages. If the pump is in sleep mode and the temperature that is measured in the pump goes below the set protection temperature, operate the pump at a constant frequency. Constant frequency is set in P3.13.10.6 Frost Protection Frequency. To use the function, a temperature transducer, or a temperature sensor must be installed on the pump covering or on the pipe line near the pump.
Use the Overpressure supervision function in a Multi-pump system. For example, when the primary valve of the pump system is closed quickly, the pressure in the pipe lines increases. The pressure can increase too quickly for the PID controller. To prevent that the pipes break, the overpressure supervision stops the auxiliary motors in the Multi-pump system.
To get the best precision and redundancy in the Multi-pump system, use the feedback sensors for each drive.
Wiring of the Feedback Sensors for Each Drive
Same sensors can also be used for all the drives. The sensor (transducer) can be supplied by a 24 V external supply or from the control board the drive.
Wiring of the Same Sensor for All Drives (Supplied from the I/O Board of the Drive)

If a sensor is supplied from the I/O board of the drive and the diodes are connected
between terminals 12 and 17, the digital inputs must be isolated from the ground. Set
the isolation DIP switch to
The digital inputs are active when they are connected to GND, which is the default condition.

B | Float |
C | Connected to GND (default) |
The Multi-pump function allows controlling a system where the maximum of 8 motors, for example, pumps, fans or compressors operate in parallel. The internal PID controller of the drive operates the necessary quantity of motors and controls the speed of the motors, when there is demand.
The motor stall protection function gives protection to the motor against short overloads. An overload can be caused, for example, by a stalled shaft. It is possible to set the reaction time of the stall protection shorter than that of the motor thermal protection.
The stall status of the motor is specified with parameters P3.9.3.2 Stall Current and P3.9.3.4 Stall Frequency Limit. If the current is higher than the limit, and the output frequency is lower than the limit, the motor is in a stall status.
The stall protection is a type of overcurrent protection.
A maintenance counter tells that maintenance must be done. For example, it is necessary to replace a belt or to replace the oil in a gearbox. There are 2 different modes for the maintenance counters, hours, or revolutions*1000. The value of the counters increases only during the RUN status of the drive.
When the value of a counter is more than its limit, an alarm, or a fault shows. It is possible connect the alarm and fault signals to a digital output or a relay output.
When the maintenance is completed, reset the counter with a digital input or parameter P3.16.4 Counter 1 Reset.
This function makes sure that the pump does not operate at a high speed when there is no demand in the system.
The function becomes active when the PID feedback signal and the output frequency of the drive stay in the specified hysteresis areas for longer than set with parameter P3.13.10.4 SNDD Supervision Time.
There are different hysteresis settings for the PID feedback signal and the output frequency. The hysteresis for the PID feedback (SNDD Error Hysteresis P3.13.10.2) is given in the selected process units around the PID setpoint value.
When the function is active, a short-time bias value (SNDD Actual Add) is added internally to the feedback value.

B | The PID feedback value |

The Soft fill function is used to move the process to a set level at a slow speed before the PID controller starts to control. If the process does not go to the set level during the timeout, a fault shows.
It is possible to use the function to fill an empty pipe slowly and prevent strong currents of water that could break the pipe.
We recommend always using the Soft fill function when using the Multi-pump function.
Use the Auto-cleaning function to remove dirt or other material from the pump impeller. It is also possible to use the function to clear a blocked pipe or valve. It is possible to use the auto-cleaning, for example, in wastewater systems to keep the performance of the pump satisfactory.
The interlocks tell the Multi-pump system that a motor is not available. It can occur when the motor is removed from the system for maintenance or bypassed for manual control.
Each of the three detection levels (Warning S1, Warning S2, Alarm/Fault) has a configurable timer associated that delays the response. The timing principle is like an electrical fuse where the response time is long for low levels and it is short for high levels.
When pressurizing a long pipe that has many outlets, the best position for the sensor is in the middle of the pipe (the position 2 in the figure). It is also possible to put the sensor directly after the pump. This gives the right pressure directly after the pump, but farther in the pipe, the pressure drops with the flow.

A | Pressure |
B | No flow |
C | With flow |
D | Pipe length |
E | Position 1 |
F | Position 2 |
Use the Flushing function to override the normal control momentarily. Use the function to flush the pipeline or operate the pump manually at the preset constant speed, for example.
The Flushing function starts the drive at a selected reference without a start command no matter the control place.
The programming of inputs of the AC drive is flexible. It is possible to use freely the available inputs of the standard and optional I/O for different functions.
It is possible to expand the available capacity of I/O with option boards. It is possible to install the option boards in the slots C, D, and E. For more data on the installation of option boards, see the Installation Guide.

It is possible to assign the output of the interval and/or timer functions to time channels 1–3. It is possible to use the time channels to control on/off type functions, for example relay outputs or digital inputs. To configure the on/off logic of the time channels, assign intervals and/or timers to them. A time channel can be controlled by many different intervals or timers.
In the following figure, the activation signal comes from a digital input or a virtual digital input, like a time channel. The timer counts down from the falling edge.
The Activation Signal from Digital Input or Virtual Digital Input
A | Remaining time |
B | Activation |
C | Duration |
D | Time |
E | OUT |
The following parameters set the timer active when the digital input 1 on the slot A is closed. They will also keep the timer active for 30 s after it is opened.
Duration: 30 s
Timer: DigIn SlotA.1
It is possible use a duration of 0 s to override a time channel that is activated from a digital input. There is no off delay after the falling edge.
Problem: The AC drive is in a warehouse and controls air conditioning. It must operate between 7 am and 5 pm on weekdays and between 9 am and 1 pm on weekends. It is also necessary for the drive to operate outside these hours, if there are personnel in the building. The drive must continue to operate 30 minutes after the personnel has left.
Solution: Set 2 intervals, 1 for weekdays and 1 for weekends. A timer is also necessary to activate the process outside the set hours. See the following configuration.

In the following figure, Time Channel 1 is used as the control signal for the start command instead of a digital input.
Time Channel 1 as the Control Signal for the Start Command
The Single drive mode controls a system of 1 variable speed pump and the maximum of 7 auxiliary pumps. The internal PID controller of the drive controls the speed of 1 pump and gives control signals with relay outputs to start or stop the auxiliary pumps. External contactors are necessary for the switch of the auxiliary pumps to the mains.
Single Drive Configuration

B | Pressure sensor |
Use the Preset frequencies function in processes where more than 1 fixed frequency reference is necessary. There are 8 preset frequency references available. The selection of a preset frequency reference can be made with the digital input signals P3.3.3.10, P3.3.3.11, and P3.3.3.12.
It is possible to program the source of the frequency reference in all the control places, except the PC tool. When using PC, it always takes the frequency reference from the PC tool.
To set the source of the frequency reference for I/O A, use the parameter P3.3.1.5.
To set the source of the frequency reference for I/O B, use the parameter P3.3.1.6.
If the default value keypad for the parameter P3.3.1.7 is used, the reference that was set for P3.3.1.8 Keypad Reference applies.
If the default value fieldbus for the parameter P3.3.1.10 is used, the frequency reference comes from fieldbus.
Use the Input pressure supervision to make sure that there is enough water in the inlet of the pump. When there is enough water, the pump does not suck air and there is no suction cavitation. To use the function, install a pressure sensor on the pump inlet.
If the input pressure of the pump goes below the set alarm limit, an alarm shows. The setpoint value of the PID controller decreases and causes the output pressure of the pump to decrease. If the pressure goes below the fault limit, the pump is stops and a fault shows.

The Input Pressure Supervision Function
The motor underload protection makes sure that there is a load on the motor when the drive operates. If the motor loses the load, a problem can occur in the process. For example, a belt can break or a pump become dry.
The motor underload protection can be adjusted with parameters P3.9.4.2 (Underload Protection: Field Weakening Area Load) and P3.9.4.3 (Underload Protection: Zero Frequency Load). The underload curve is a squared curve between the zero frequency and the field weakening point. The protection is not active below 5 Hz. The underload time counter does not operate below 5 Hz.
The values of the underload protection parameters are set in percentage of the nominal torque of the motor. To find the scaling ratio for the internal torque value, use the data in the nameplate data of the motor, the motor nominal current, and the nominal current of the drive IH. If another current than the nominal motor current is used, the precision of the calculation decreases.
The parameters are functions that can be connected to a digital input terminal. The text DigIn Slot A.2 means the second input on the slot A. It is also possible to connect the functions to time channels. The time channels work as terminals.
It is possible to monitor the statuses of the digital inputs and the digital outputs in the Multimonitoring view.
A priming pump is a smaller pump that primes the inlet of the main pump to prevent suction of air.
The priming pump function controls a priming pump with a digital output signal. It is possible to set a delay to start the priming pump before the main pump starts. The priming pump operates continuously while the main pump operates. If the main pump goes into sleep mode, the priming pump also stops for that time. When waking up from sleep mode, the main pump, and the priming pump start simultaneously.

In the standard I/O board compilation, there are 2 analog inputs available: the slot A terminals 2/3 and 4/5.
Input type (graphical display) | Input type (text display) | Slot | Input # | Explanation |
---|---|---|---|---|
AnIN | AI | A | 1 | Analog input #1 (terminals 2/3) on a board in Slot A (standard I/O board). |
AnIN | AI | A | 2 | Analog input #2 (terminals 4/5) on a board in Slot A (standard I/O board). |
The location of the parameter P3.5.2.1.1 AI1 Signal Selection is the menu M3.5.2.1. The parameter gets the default value AnIN SlotA.1 in the graphical display or AI A.1 in the text display. The target input for the signal of the analog frequency reference AI1 is then the analog input in the terminals 2/3. Use the DIP switches to set the signal to be voltage or current. See the Installation manual for more data.
Index | Parameter | Default | ID | Description |
---|---|---|---|---|
P3.5.2.1.1 | AI1 Signal Selection | AnIN SlotA.1 | 377 |
To change the input from AI1 to, for example, the analog input on your option board in slot C, obey these instructions.
The Multidrive modes (Multimaster and Multifollower) control a system that has the maximum 8 variable speed pumps. Each pump is controlled by a drive. The internal PID controller of the drive controls all pumps. The drives use a communication bus (Modbus RTU) for communication.
The figure shows the Multidrive configuration principle. See also the general electric
diagram of a Multi-pump system in
Multidrive Configuration
A | Start / Stop |
B | Pressure sensor |
The AC drive has different counters based on the operation time of the drive and the energy consumption. Some of the counters measure total values and some can be reset.
The energy counters measure the energy that is taken from the supply network. The other counters are used to measure, for example, the operation time of the drive or the run-time of the motor.
It is possible to monitor all the counter values from the PC, control panel, or fieldbus. When using the PC or the control panel, it is possible to monitor the counter values in the Diagnostics menu. When using fieldbus, it is possible to read the counter values with the ID numbers.
The timer functions make it possible for the internal RTC (real-time clock) to control functions. All the functions that can be controlled with a digital input, can also be controlled with the RTC, with time channels 1–3. It is not necessary to have an external PLC to control a digital input. It is possible program the closed and opened intervals of the input internally.
To get the best results of the timer functions, install a battery, and make the settings of the real-time clock carefully in the Start-up wizard. The battery is available as an option.
The monitoring values related to temperature input settings are only available if a B8 or BH option board is installed.
The frequency reference of the Motor Potentiometer is available in all the control places. It is possible to change the motor potentiometer reference only when the drive is in the run state.
Before or after baseline run, each measurement point can be modified by parameter. One array includes 10 points in steady state and 9 points in ramp state.
In some processes, it can be necessary to avoid some frequencies because they make problems of mechanical resonance. With the Prohibit frequencies function, it is possible to prevent the usage of these frequencies. When the input frequency reference increases, the internal frequency reference stays at the low limit, until the input frequency reference is above the high limit.
Find the applicable functions for digital inputs as parameters in parameter
group M3.5.1. To give a digital input to a function, set a value to the correct

In the standard I/O board compilation, there are 6 digital inputs available: the slot A terminals 8, 9, 10, 14, 15 and 16.
Input type (graphical display) | Input type (text display) | Slot | Input # | Explanation |
---|---|---|---|---|
DigIN | dI | A | 1 | Digital input #1 (terminal 8) on a board in Slot A (standard I/O board). |
DigIN | dI | A | 2 | Digital input #2 (terminal 9) on a board in Slot A (standard I/O board). |
DigIN | dI | A | 3 | Digital input #3 (terminal 10) on a board in Slot A (standard I/O board). |
DigIN | dI | A | 4 | Digital input #4 (terminal 14) on a board in Slot A (standard I/O board). |

DigIN | dI | A | 6 | Digital input #6 (terminal 16) on a board in Slot A (standard I/O board). |
The function External Fault Close, the location of which is the menu M3.5.1, is parameter P3.5.1.11. It gets the default value DigIN SlotA.3 in the graphical display, and dI A.3 in the text display. After this selection, a digital signal to the digital input DI3 (terminal 10) controls External Fault Close.
Index | Parameter | Default | ID | Description |
---|---|---|---|---|
P3.5.1.11 | External fault close | DigIN SlotA.3 | 405 |
OPEN = OK CLOSED = External fault |
To change the input from DI3 to, for example, DI6 (terminal 16) on the standard I/O, obey these instructions.
For stator winding monitoring, the motor currents are being evaluated for evolving unbalances. For this purpose, current unbalance is computed and monitored. If there are the unbalanced grid voltages, a resonance-like oscillation can occur if the motor frequency matches the grid frequency.
The Anti-blocking function makes the pump not to get blocked if the pump is stopped in the Sleep mode for a long time. The pump starts at intervals, while it is in the Sleep mode. It is possible to make a configuration of the interval, run-time, and speed for the anti-blocking.
Start and stop commands must be given differently in each control place.
Use the parameters P3.5.1.1 (Control signal 1 A), P3.5.1.2 (Control signal 2 A) and P3.5.1.3 (Control signal 3 A) to select digital inputs. These digital inputs control the start, stop, and reverse commands. Then select a logic for these inputs with P3.2.6 I/O A Logic.
Use the parameters P3.5.1.4 (Control signal 1 B), P3.5.1.5 (Control signal 2 B) and P3.5.1.6 (Control signal 3 B) to select digital inputs. These digital inputs control the start, stop, and reverse commands. Then select a logic for these inputs with P3.2.7 I/O B Logic.
The start and stop commands come from the keypad buttons. The direction of the rotation is set with parameter P3.3.1.9 Keypad direction.
Start, stop, and reverse commands come from the fieldbus.
When Fire mode is active, the drive resets all faults that occur and continues to operate at the same speed until it is not possible. The drive ignores all commands from the keypad, fieldbuses, and the PC tool. It only obeys the signals Fire Mode Activation, Fire Mode Reverse, Run Enable, Run Interlock 1, and Run Interlock 2 from I/O.
The Fire mode function has 2 modes, the Test mode, and the Enabled mode. To select a mode, write a password in parameter P3.17.1 (Fire Mode Password). In the Test mode, the drive does not automatically reset the faults, and the drive stops when a fault occurs.
It is also possible to configure Fire mode with the Fire mode wizard, which can be activated in the Quick Setup menu with parameter B1.1.4.
When the Fire mode function is activated, an alarm shows on the display.
The motor thermal protection prevents the motor from becoming too hot.
The AC drive can supply a current that is higher than the nominal current. The high current can be necessary to the load, and it must be used. In these conditions, there is a risk of a thermal overload. Low frequencies have a higher risk. At low frequencies, the cooling effect and the capacity of the motor decrease. If the motor has an external fan, the load reduction at low frequencies is small.
The motor thermal protection is based on calculations. The protection function uses the output current of the drive to know what is the load on the motor. If the control board is not energized, the calculations are reset.
To adjust the thermal protection of the motor, use the parameters from P3.9.2.1 to P3.9.2.5. It is possible to monitor the thermal status of the motor on the display of the control panel.
With a PM motor, use the I/f Start function to start the motor with constant current control. A high power motor gives the best effect. With a high power motor, the resistance is low and it is not easy to change the U/f curve.
The I/f Start function can also give a sufficient torque for the motor at start up.
The I/f Start Parameters
A | I/f Start Current |
B | Output Frequency |
C | Motor Current |
D | I/f Start Frequency |
Use the feedback supervision to make sure that the PID Feedback value (the process value or the actual value) stays in the set limits. Use this function, for example, to find a pipe break and stop the flooding.
These parameters set the range in which the PID Feedback signal stays in correct conditions. If the PID Feedback signal does not stay in the range, and this continues longer than the delay, a Feedback supervision fault (the fault code 101) shows.
In the Multi-pump system, the time that each pump operates is monitored by a run-time counter. For example, the order that the pumps start is specified by the run-time counter values to make the wear of the pumps in the system more equal. The pump run-time counters also tell the operator to do maintenance on a pump (parameters P3.15.19.4 - P3.15.19.5).
The Pump run-time counters are in the monitoring menu, see

Selection number | Selection name | Description |
---|---|---|
0 | Linear | The voltage of the motor changes linearly as a function of the output frequency. The voltage changes from the value of P3.1.4.6 (Zero Frequency Voltage) to the value of P3.1.4.3 (Voltage at Field Weakening Point) at a frequency set in P3.1.4.2 (Field Weakening Point Frequency). Use this default setting if a different setting is not necessary. |
1 | Squared | The voltage of the motor changes from the value of P3.1.4.6 (Zero Frequency Voltage) to the value of P3.1.4.2 (Field Weakening Point Frequency) at a squared curve. The motor operates undermagnetized below the field weakening point and produces less torque. Use the squared U/f ratio in applications where the torque demand is in relation to the square of the speed, for example in centrifugal fans and pumps. |
2 | Programmable | It is possible to program the U/f curve with 3 different points: the zero frequency voltage (P1), the midpoint voltage/ frequency (P2), and the field weakening point (P3). Use the programmable U/f curve at low frequencies if it is necessary to have more torque. Use the identification run (P3.1.2.4) to find the optimal settings automatically. |

Use this parameter to adjust the stator voltage in permanent magnet motors.
It is possible to use this parameter only when the parameter P3.1.2.2 Motor Type has the value PM motor. If induction motor is selected as the motor type, the value is automatically set to 100%, and the value cannot be changed.
When changing the value of P3.1.2.2 (Motor type) to PM Motor, the parameters P3.1.4.2 (Field Weakening Point Frequency) and P3.1.4.3 (Voltage at Field Weakening Point) increase automatically to be equal with output voltage of the drive. The set U/f ratio does not change. This is done to prevent the operation of the PM motor in the field weakening area. The nominal voltage of the PM motor is much lower than the full output voltage of the drive.
The nominal voltage of the PM motor agrees to the back EMF voltage of the motor at nominal frequency. But in a different motor manufacturer, it can be equal to, for example, the stator voltage at nominal load.

Use this parameter to adjust the gain of the feedback signal. This parameter is used, for example, with the value 2 in Feedback Function.
Location in the menu: P3.13.4.1
Use this parameter to select if the feedforward value is taken from a single signal or combined from two signals. It is possible to select the mathematical function that is used when the two feedforward signals are combined.
Accurate process models are necessary for the Feedforward function. In some conditions, a gain and offset type of feedforward is sufficient. The feedforward part does not use the feedback measurements of the actual controlled process value. The feedforward control uses other measurements that affect the controlled process value.
It is possible to control the water level of a tank with flow control. The target water level is set as a setpoint, and the actual level as feedback. The control signal monitors the flow that comes in.
The outflow is like a disturbance that can be measured.

Use this parameter to set the flying start options. The parameter Flying Start Options has a checkbox selection of values.
The bits can receive these values.
Search the shaft frequency only from the same direction as the frequency reference
Disable the AC scanning
Use the frequency reference for an initial guess
Disable the DC pulses
Flux build with current control
The bit B0 controls the search direction. With the bit set to 0, the shaft frequency is searched in 2 directions, the positive and the negative. With the bit set to 1, the shaft frequency is searched only in the frequency reference direction. It prevents the shaft movements for the other direction.
The bit B1 controls the AC scanning that premagnetizes the motor. In the AC scanning, the system sweeps the frequency from the maximum towards zero frequency. The AC scanning stops when an adaptation to the shaft frequency occurs. To disable the AC scanning, set the bit B1 to 1. If the value of Motor Type is permanent magnet motor, the AC scanning is disabled automatically.
Use the bit B5 to disable the DC pulses. The primary function of the DC pulses is to premagnetize the motor and examine the rotation of the motor. If the DC pulses and the AC scanning are enabled, the slip frequency tells which procedure is applied. If the slip frequency is less than 2 Hz, or the motor type is PM motor, the DC pulses are disabled automatically.
The bit B7 controls the rotation direction of the injected high frequency signal, which is used in the flying start of synchronous reluctance machines. Signal injection is used to detect the frequency of the rotor. If the rotor is in a blind angle when the signal is injected, the rotor frequency is undetectable. Reversing the rotation direction of the injection signal solves this problem.

This parameter specifies the operation mode (master or slave) in the Multi-pump system. The drives that have the start command and the PID feedback signals connected, can operate as the master drive in the Multi-pump system. If there are many drives in the Multi-pump system that have all the signals connected, the drive with the lowest Pump ID Number (P3.15.3) starts to operate as the master.
Location in the menu: P3.15.1
Use this parameter to select the configuration and the control mode of the Multi-pump system. The Multi-pump function allows controlling a maximum of 8 motors (that is, pumps, fans, compressors) with the PID control.
The Single drive mode controls a system that has 1 pump that can change speed and the maximum of 7 auxiliary pumps. The internal PID controller of the drive controls the speed of 1 pump and gives control signals with relay outputs to start or stop the auxiliary pumps.
External contactors are necessary for the switch of the auxiliary pumps to the mains. 1 of the pumps is connected to the drive and controls the system. When the pump in control sees that it is necessary to have more capacity (operates at the maximum frequency), the drive gives the control signal with the relay output to start the next auxiliary pump. When the auxiliary pump starts, the pump in control continues to control and starts from the minimum frequency.
When the pump that controls the system sees that there is too much capacity (operates at the minimum frequency), the pump makes the started auxiliary pump to stop. If no auxiliary pumps operate when the pump in control sees the overcapacity, the pump goes to the Sleep mode (if the Sleep function is enabled).
Control in the Single Drive Mode
P1 | The pump that controls the system |
B | The auxiliary pumps connected to the mains (direct on-line) |
The Multifollower mode controls a system that has the maximum 8 pumps that can change speed. Each pump is controlled by a drive. The internal PID controller of the drive controls all the pumps.
1 of the pumps always controls the system. When the pump in control sees that it is necessary to have more capacity (operates at the maximum frequency), the pump uses the communication bus to make the next pump to start. The next pump increases speed and starts to operate at the speed of the pump in control. Auxiliary pumps operate at the speed of the pump that controls the system.
When the pump that controls the system sees that there is too much capacity (operates at the minimum frequency), it makes the started pump to stop. If no auxiliary pumps operate when the pump in control sees overcapacity, the pump goes to the Sleep mode (if the Sleep function is enabled).
Control in the Multifollower Mode
P1 | The pump controls the system. |
P2 | The pump follows the speed of P1. |
P3 | The pump follows the speed of P1. |
A | Curve A shows the auxiliary pumps that follow the speed of pump 1. |
The Multimaster mode controls a system that has the maximum 8 pumps that can change speed. Each pump is controlled by a drive. The internal PID controller of the drive controls all the pumps.
1 of the pumps always controls the system. When the pump in control sees that it is necessary to have more capacity (operates at the maximum frequency), it locks to a constant production speed and makes the next pump to start and to control the system.
When the pump that controls the system sees that there is too much capacity (operates at the minimum frequency), it stops. The pump that operates at a constant production speed starts to control the system. If there are many pumps that operate at a constant production speed, the started pump starts to control the system. If no pumps operate at a constant production speed when the pump in control sees the overcapacity, the pump goes to the Sleep mode (if the Sleep function is enabled).

Location in the menu: P3.13.5.5
Use this parameter to set the value that is added to the actual setpoint value when the sleep boost function is used. Before the drive goes to the sleep state, the PID regulation setpoint increases automatically, which gives a higher process value. The sleep state is longer, also when there is some moderate leakage.
The boost level is used when there is a frequency threshold and delay, and the drive goes to the sleep state. After the increment in the setpoint by the actual value, the boost increment of the setpoint is erased and the drive goes to the sleep state and the motor stops. The boost increment is positive with the direct PID regulation (P3.13.1.8 = Normal) and negative with the reverse PID regulation (P3.13.1.8 =Inverted).
If the actual value does not go to the increment setpoint, the boost value is erased after the time set with P3.13.5.5. The drive goes to the normal regulation with the normal setpoint.
In a Multi-pump setup, if an auxiliary pump starts during the boost, the boost sequence stops and the normal regulation continues.

Use this parameter to set the current limit for the run indication signal of the relay output.
This parameter only affects if the value "Run indication" is selected for a relay output and the fire mode is active. The "Run indication" relay output function tells quickly if current is supplied to the motor during a fire.
The value of this parameter is the percentage counted from the motor nominal current. If there is a fire and the current that is supplied to the motor is more than the nominal current times the value of this parameter, the relay output closes.
For example, if parameter Motor Nominal Current has the value 5 A, and 20% is set as the default value of this parameter, the relay output closes and Fire Mode activates when the output current goes to 1 A.
This parameter does not affect if the fire mode is not active. In normal operation, if "Run indication" is selected for a relay output, the result is the same as when "Run" is selected for the relay output.
