Turn off the adjustable frequency drive and
check motor phase U.
ALARM 31, Motor phase V missing:
Motor phase V between the adjustable fre-
quency drive and the motor is missing.
Turn off the adjustable frequency drive and
check motor phase V.
ALARM 32, Motor phase W missing:
Motor phase W between the adjustable fre-
quency drive and the motor is missing.
Turn off the adjustable frequency drive and
check motor phase W.
ALARM 33, Soft-charge fault:
Too many power-ups have occured within a
short time period. See the chapter
