NB!
Max. output frequency cannot exceed 10% of the inverter switching frequency (par. 14-01).
4-16 Torque Limit Motor Mode
Range:
*
[0.0 - Variable Limit %] Sets the torque limit for motor operation. The torque limit is active in the speed range up to the rated motor
160.0 %
Changing par. 4-16
automatically readjusted.
4-17 Torque Limit Generator Mode
Range:
*
[0.0 - Variable Limit %] Sets the torque limit for generator mode operation. The torque limit is active in the speed range up to the rated
160.0 %
4-18 Current Limit
Range:
* [0.0 - Variable Limit %] Enter the current limit for motor and generator mode operation. The default setting is 1.6 x the rated motor
160.0 %
4-19 Max Output Frequency
Range:
*
132.0 Hz [0.0 - 1000.0 Hz]
NB!
Max. output frequency cannot exceed 10% of the inverter switching frequency (par. 14-01).
Function:
speed (par. 1-25). To protect the motor from reaching the stalling torque, the default setting is 1.6 x the rated
motor torque (calculated value). If a setting in par. 1-00 to par. 1-26 is changed, par. 4-16 to 4-18 are not
automatically reset to the default settings.

Function:
current (set in par. 1-24). If a setting in par. 1-00 to par. 1-26 is changed, par. 4-16 to par. 4-18 are not auto-
matically reset to the default settings.
To obtain maximum output torque and prevent the motor from stalling, it is recommendable
lower than par. 4-16 and 4-17 (Torque Limits)
Function:
Provides a final limit on the output frequency for improved safety in applications where you want to avoid acci-
dental over-speeding. This limit is final in all configurations (independent of the setting in par. 1-00).
