CONVERTER RADIATOR FAN FAILURE

What does 606 n AXIS: CNV. RADIATOR FAN FAILURE mean?

This warning signal on the Fanuc Series 0i-D/0i Mate-D αi servo system indicates a failure of the converter radiator fan. This condition (SVWRN4, SVWRN3, and SVWRN1 active) will eventually result in a converter overheat alarm if the cooling issue is not resolved.

• Failure of the cooling fan responsible for the converter's radiator.
• Accumulation of dust or debris on the radiator fins or fan blades, impeding airflow.
• Poor electrical connection or power supply to the radiator fan.

Click steps to track your progress.

1. 1

   Inspect the converter radiator fan for any physical damage, debris accumulation, or obstructions.

2. 2

   Verify all electrical connections to the radiator fan for secure contact and proper voltage supply.

3. 3

   Confirm fan rotation during operation and listen for any abnormal sounds indicative of bearing failure or obstruction.

4. 4

   Ensure that the radiator fins and air channels for the converter are clean and free of dust or other foreign material.

5. 5

   If the fan is not operating or is mechanically compromised, replace the converter radiator fan.
