Cntl Bd Overtemp

What does 55 mean?

The temperature sensor on the Main Control Board has detected an excessive heat condition, exceeding safe operating limits. This indicates that the control electronics are overheating, which can lead to instability or damage to the drive. Possible causes include inadequate cooling or a high ambient temperature.

• Internal temperature sensor on the control board detected overheating.
• High ambient temperature affecting control board performance.
• Fan failure for control board cooling.
• Overload conditions stressing control circuitry.

1. 1

   Visually inspect the Main Control Board fan for proper operation and airflow.

2. 2

   Measure the surrounding air temperature to ensure it is within the drive's specified operating range.

3. 3

   Verify the drive's mounting and cooling system for proper airflow and heat dissipation, ensuring no obstructions.
