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.
