14-12 Response to Mains Imbalance
Option: Function:
Operation under severe mains imbalance
conditions reduces the lifetime of the motor.
Conditions are considered severe if the motor is

parameter 14-20 Reset Mode
reverts to the original selection.
If the number of automatic
resets is not reached within 10
minutes, or when a manual reset
is performed, the internal
