On newer controls, alarm 366 often appears when using an for a system variable incorrectly.
If the alarm follows the cable during testing, replace the feedback cable with a high-flex, double-shielded CNC cable to prevent future failure from repetitive machine motion. Drive Repair
Follow this structured diagnostic workflow to isolate the root cause before buying expensive replacement parts. 1. Perform a Power Cycle Turn off the CNC machine completely. Wait 30 seconds for the capacitors to discharge. Power the machine back on.
Look at the diagnostic parameters for the servo axis (typically in the 200–300 or 700 range depending on the FANUC control model, such as 16i/18i/21i or 0i-D/F).
