Cause : W-phase error comes when the drive is detecting an abnormality in the current flowing through the W phase of the motor.

The cd3 error code on your Delta MS300 drive indicates a W-phase current fault. This means the drive is detecting an abnormality in the current flowing through the W phase of the motor connected to the drive. 

  1. Cycle the power.
  2. Check drive IGBT using multimeter.
