INVERTER RADIATOR FAN FAILURE

What does 601 n AXIS: INV. RADIATOR FAN FAILURE mean?

This warning signal on the Fanuc Series 0i-D/0i Mate-D αi servo system indicates a failure of the inverter radiator fan. This condition (SVWRN4 and SVWRN1 active) will eventually lead to an inverter overheat alarm if the cooling issue persists.

• Failure of the cooling fan responsible for the inverter'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.
