On
Function:
Selects monitoring of the motor phases. If you
select On, the frequency converter reacts on a
missing motor phase and displays an alarm. If you
select Off, no alarm is returned if a motor phase is
missing. If the motor runs on only two phases, it
can be damaged/overheated. Thus, do not change
the missing motor phase function On. You cannot
set this parameter while the motor is running.
