Parameter descriptions
574 Power Limit
575 Limitation Time
The threshold selected via parameter Operation Mode 573 is monitored. If parameter Operation
Mode
573 is selected to motor or heat sink temperature monitoring, the power is reduced to the val-
ue of
Power Limit 574 once the limit value is reached. The power is reduced until the temperature
has dropped sufficiently. You can set an additional time
Limitation Time 575 for which the limitation
after falling below the limit value should be maintained. In motor operation, the output current and
the speed will be reduced. The load behavior of the motor must depend on the speed.
The power limit should be selected as small as possible in order to give the drive sufficient time to
cool down. The reference value is the rated output of the frequency inverter or the set rated power of
the motor.
574 Power Limit 40.00% 95.00% 80.00%
Output signals
Reaching of a limit – selected in
Operation Mode 573 – can be signaled via digital outputs.
Warning Current Limitation
The intelligent current limits limit the output current.
