has dropped sufficiently. You can set an additional time
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.
