■ Timing chart (setting example)
When function numbers "102", "103" (switch to commercial power run) is set to terminal [S3].
Terminal [S3] ON: commercial power operation
Terminal [S3] OFF: inverter operation
Switching cannot be performed properly if standby function is OFF.

Important
• To allow switching to commercial power operation, forward run of the inverter and the direction
of rotation of the motor for commercial power operation must match.
• Do not set <F311: Reverse inhibited> to "2: Fwd inhibited". The inverter will not be able to
forward run and switching to commercial power cannot be accomplished.
• This function can only be used in induction motors. Do not use this function with PM motors.
