Cause : Over voltage when deceleration comes when the drive internal main circuit DC voltage to reach or exceed the specified value.

  1. The protection circuit is activated to stop the inverter output.
  2. The circuit may also be activated by a surge voltage produced in the power supply system.
  3. Increase the deceleration time.
  4. Add suitable brake devices.
