“P.oFF”
is reported
when the drive
begin to run
immediately
Transistor or
contactor
disconnected and
overload
Since the transistor or contactor is
disconnected, the bus voltage
drops at heavy load, therefore, the
drive
displays P.Off, not E018
Run the drive until the transistor or
contactor is connected.
