[Cause]
Motion processing, communication processing, and approach stop and approach wait processing in the controller are overloaded. The interpolation period may be too short for the current robot settings.
[Countermeasure]
Before performing other operations (power-off and jogging operations) after this alarm occurs, execute the abnormal-condition recording function (“Abnormal Condition Record” in the auxiliary menu), obtain an image backup, and then 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.
