Over-voltage during deceleration

DC bus over-voltage during deceleration.
When ovd occurs, the drive closes the gate of the
output immediately, the motor runs freely, and the
display shows an ovd error.

1. Increase the setting value of Pr.01-13, Pr.01-15, Pr.01-17 and Pr.01-19
(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 (Pr.06-01).
7. Use auto-acceleration and auto-deceleration (Pr.01-44).
8. Adjust the braking level (Pr.07-01 or the bolt position of the brake unit

Check the wiring of the brake resistor or braking unit.
