Phase loss
protection
Trips the motor depending of the trip class withinseconds
in case of a phase loss. This parameter must be set to On during
regular operation.
Note: If the voltage module
is present this parameter
activates both voltage and
current based phase loss
detection.

If enabled the three phases must be fed through the UMC CTs in
Note: If the voltage module
is present this parameter must
not be changed.

Note: If the voltage module
is present this parameter
activates both voltage and
current based phase sequence
protection.
