4-58 Missing Motor Phase Function
Option:
Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
The missing motor phase function detects
whether the motor phase is missing during
motor rotation. Shows alarm 30, 31, or 32 in the
event of a missing motor phase. Enable this
function to avoid motor damage.

The frequency converter does not issue a missing
motor phase alarm. Not recommended due to
risk of motor damage.
