Cause : Excess temperature - comes when Power unit module temperature is excessive due to fan not working or heatsink fins for dust pick-up. Follow these steps to correct fault :

  1. Check ambient conditions.
  2. Check air flow and fan operation.
  3. Check heatsink fins for dust pick-up.
  4. Check motor power against drive power.
