- 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 (
H
=
) of
H
(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.
