[3] Closed loop Motor Speed will be determined by a reference 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-** Drive Closed Loop or via the Function Setups accessed by pressing the [Quick Menus] button.
This parameter can not be changed when motor is running.
NB!
When set for Closed Loop, the commands Reversing and Start Reversing will not reverse the direction of the motor.
1-20 Motor Power [kW]
Range: Function:
Size related * [0.09 - 1200 kW]
Enter the nominal motor power in kW according to the motor nameplate data. The default value corresponds to
the nominal rated output of the unit.
This parameter cannot be adjusted while the motor is running. Depending on the choices made in par.
0-03
Regional Settings
, either par. 1-20 or par. 1-21 Motor Power is made invisible.
1-22 Motor Voltage
Range: Function:
Size related * [10 - 1000 V]
Enter the nominal motor voltage according to the motor nameplate data. The default value corresponds to the
nominal rated output of the unit.
This parameter cannot be adjusted while the motor is running.
1-23 Motor Frequency
Range: Function:
Size related * [20 - 1000 Hz]
Select the motor frequency value from the motor nameplate data. For 87 Hz operation with 230/400 V motors,
set the nameplate data for 230 V/50 Hz. Adapt par. 4-13
Motor Speed High Limit [RPM) and par. 3-03 Maximum
Reference
to the 87 Hz application.
This parameter cannot be adjusted while the motor is running.
1-24 Motor Current
Range: Function:
Size related * [0.1 - 10000 A]
Enter the nominal motor current value from the motor nameplate data. This data is used for calculating motor
torque, motor thermal protection etc.
This parameter cannot be adjusted while the motor is running.
1-25 Motor Nominal Speed
Range: Function:
Size related * [100 - 60,000 RPM]
Enter the nominal motor speed value from the motor nameplate data. This data is used for calculating automatic
motor compensations.
This parameter cannot be adjusted while the motor is running.
1-29 Automatic Motor Adaptation (AMA)
Option: Function:
The AMA function optimizes dynamic motor performance by automatically optimizing the advanced motor pa-
rameters (par. 1-30 to par. 1-35) while the motor is stationary.
