Code Description
PRT-32 No Motor
Level,
PRT-33 No Motor Time
If the output current value [based on the rated current (BAS-13)] is
lower than the value set at PRT-32 (No Motor Level), and if this
continues for the time set at PRT-33
(No Motor Time), a ‗no motor
trip‘ occurs.
If BAS-
07 (V/F Pattern) is set to ‗1 (Square)‘, set PRT-32 (No Motor Level) to a value lower than
the factory default. Otherwise, a ‗no motor trip,‘ due to a lack of output current, will occur when
the ‗no motor trip‘ operation is set.
