Internal system error.
[Countermeasure]
1. Restart the program after clearing the alarm.
2. If the same alarm occurs, power on again to return the robot to the origin position, and then execute the program.
3. If the above countermeasures do not resolve the problem, before performing other operations (power-off and jogging operations) after this alarm occurs, use the abnormal-condition recording function ("Abnormal Condition Record" in the auxiliary menu) to obtain an image backup and contact the 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.
