- Warning -
• When switching to commercial power, make sure that the direction in which the motor rotates when
operated on commercial power agrees with the forward direction when operated via the inverter.
• Do not select any option (=, ) of  (reverse rotation prohibition selection) that prohibits
forward rotation. Or it becomes impossible to switch to commercial power, because the motor cannot
rotate in the forward direction.
