FANUC Parameter #8901 is a critical bit-setting used to control the retention of workpiece coordinate systems (G54-G59, etc.) during specific reset or power-cycle conditions. When enabled (set to 1), it prevents the CNC from accidentally clearing or defaulting the work offsets stored in the G54 range, providing a layer of security against data loss and setup errors.
Would you like a step-by-step procedure to change 8901 on your specific Fanuc model (e.g., 0i-D, 31i-B5) or a sample PMC ladder modification to remove the deceleration dog input? fanuc parameter 8901 better
