Cause : Over-voltage during deceleration comes when the voltage generated by the motor as it decelerates has exceeded the set limit on the drive.

The ovd fault in Delta drive indicates an Over-voltage during Deceleration condition. This means the voltage generated by the motor during the deceleration phase has exceeded a set limit.

1. Increase the setting value deceleration time.
2. Connect the brake resistor, braking unit or DC bus on the drive.
3. Reduce the brake frequency.
4. Replace the drive with a larger capacity model.
5. Use S-curve acceleration/deceleration.
6. Use over-voltage stall prevention.
7. Use auto-acceleration and auto-deceleration.
8. Adjust the braking level.
