Terminal R2 function
• 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 for-
ward 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.
