Title
 Commercial power/inverter switching output selection
 Commercial power/inverter switching frequency
 Inverter-side switching waiting time
 Commercial power-side switching waiting time
 Commercial power switching frequency holding time
 Input terminal function selection 7 (S3)
 Output terminal function selection 1 (OUT1)
 Output terminal function selection 2 (OUT2)
- 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.
