Cause : U-phase error comes when the drive is detecting an abnormality in the current flowing through the U phase of the motor.
The cd1 error code on your Delta MS300 drive indicates a U-phase current fault. This means the drive is detecting an abnormality in the current flowing through the U phase of the motor connected to the drive.
- Cycle the power.
- Check drive IGBT using multimeter.
