Over-heat of Control Module (ECM)

Hva betyr 9 ?

The Energy Charge Module's (ECM) Control Module has detected an abnormal over-heat condition via its built-in thermostat. Continuous operation in this state can shorten the life of electronic components and degrade ECM performance, potentially leading to other failures.

• Control module (ECM) temperature exceeds operational limit P1-80.
• Cooling fan failure or obstruction for the ECM.
• Excessive ambient temperature around the ECM.
• High operational load causing increased heat generation within the ECM.
• Blocked heatsink or ventilation on the ECM.

1. 1

   Immediately stop the machine using the emergency stop button and open the external Main Circuit Contactor (MCC) of the Power supply.

2. 2

   Check the cooling fan of the Control Module (A06B-6158-H010) for proper operation and ensure it is not blocked by dust or debris.

3. 3

   Verify that the ambient temperature around the Control Module is within the specified operating range (0 to 55°C, page 49).

4. 4

   Ensure proper ventilation and air circulation within the power magnetics cabinet (Section G.2.3, page 460). Clear any obstructions.

5. 5

   Inspect the heat sink of the Control Module for dust accumulation or damage, which can reduce cooling efficiency.
