DC Overvoltage

What does 7 mean?

The DC bus voltage has exceeded its safe operating limit. This condition can lead to component stress and potential damage to the drive. It is often caused by high mains voltage or regenerative energy from the motor during deceleration.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Adjust motor deceleration ramps to be longer if overvoltage occurs during stopping, to manage regenerative energy.
