If this occurs because the tracking parameter setup table number was changed while the program was paused, do not perform that operation. Turn the robot controller power off and on again to clear the alarm. If this alarm occurs under other conditions, before performing other operations (power-off and jogging operations) after the alarm occurs, execute the abnormal-condition recording function (“Abnormal Condition Record” in the auxiliary menu), obtain an image backup, and contact the FANUC service center. If the abnormal-condition recording function cannot be used, record the conditions and operating steps leading up to the alarm, obtain an image backup, and contact the service center.
