The CNC controller monitors the fan. If the fan fails, the alarm is triggered, and the machine may stop. fanuc parameter 8901 better
If you change Parameter 8901 to 1 to finish a critical production run, you must introduce external cooling. Open the electrical cabinet door and position an industrial floor fan or a vortex cooling tube directly toward the Fanuc control unit modules. This mitigates the risk of frying your main CPU or axis cards while the onboard fan is inactive. 2.
