Cause : Drive over-heat based on thermal model comes when the drive will attempt to stop the motor before tripping. If the motor does not stop in 10 seconds the drive trips immediately.

  1. Thermal model looks at DC Bus ripple as well as output current.
  2. This is to protect the DC Bus stage from overheating.
