The VFD’s input is insensitive to the phase sequence of the input voltage. Therefore, changing the input phase sequence will not change the rotation of the motor. However, changing the phase sequence of the VFD’s output will change the motor rotation. When applying a VFD, the motor rotation should always be checked prior to connecting the driven equipment. If the motor is rotating in the wrong direction, reverse any two of the AC motor leads to change the rotation of the motor. Do not change the motor direction via the VFD’s software parameters. Although changing the VFD’s parameters can change the motor rotation, if the parameters are reset to the factory defaults, the motor will then rotate in the opposite direction.
