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.
See also chapter 3.5.5 Combinations of parameters
4-58 and 4-59.
[0] Disabled The frequency converter does not issue a missing
motor phase alarm. Not recommended due to
risk of motor damage.
[1] Trip 100 For a quick detection time and alarm in the
ms event of a missing motor phase.
[2] Trip 1000
ms
[3] Trip Special option relevant for crane applications
100ms when lowering a small load that lets the
3ph frequency converter avoid false detections of
detec. missing motor phase.
