Drivecon ROT fault code meaning

Series: VF51RG regenerative unit

Phase rotation error (ROT)

AC drive

Meaning: Driving a converter in reverse phase order does not cause any particular trouble, but regenerative power capability is slightly (around 5%) reduced under FCL condition; 'ROT' trip is illuminated on LED display. | Correct by reversing two incoming phases directly at power source coupling point, not at regenerative converter input.
