[Cause]
This is an internal system error of the weld condition ramping function.
[Countermeasure]
Turn the power off and on again. If the problem persists, 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), 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.
