Motor size
0.25 kW - 7.5 kW
Select the motor frequency value from the motor nameplate data. If a value different from 50 Hz or 60
Hz is selected, it is necessary to adapt the load independent settings in par. H-50 Motor Magnetisation at
Zero Speed to par. H-53 Model Shift Frequency. For 87 Hz operation with 230/400 V motors, set the name-
plate data for 230 V/50 Hz. Adapt par. F-17 Motor Speed High Limit [RPM] and par. F-53 Maximum
Reference to the 87 Hz application.
Function:
Enter the nominal motor voltage according to the motor nameplate data. The default value corresponds
to the nominal rated output of the unit.
Function:
Enter the accel time, i.e. the acceleration time from 0 RPM to the synchronous motor speed n
accel time such that the output current does not exceed the current limit in par. F-43 Current Limit during
ramping. The value 0.00 corresponds to 0.01 sec. in speed mode. See decel time in par. F-08 Decel Time
1.

Function:
Enter the decel time, i.e. the deceleration time from the synchronous motor speed n
decel time such that no over-voltage arises in the inverter due to regenerative operation of the motor,
and such that the generated current does not exceed the current limit set in par. F-43 Current Limit. The
value 0.00 corresponds to 0.01 s in speed mode. See accel time in par. F-07 Accel Time 1.

ref RPM
Function:
Enter the % value to compensate voltage in relation to load when the motor is running at low speed and
obtain the optimum U/f characteristic. The motor size determines the frequency range within which this
parameter is active.
