[Cause]
The communication delay between the robot and welding equipment (t1) is longer than the weld condition ramping update cycle (t2), so the welding conditions cannot be updated in time and weld condition ramping could not continue. This alarm occurs when the weld condition ramping function or thermal wave mode 2 is executed.
[Countermeasure]
Usually occurs immediately before ARC-133. When ARC-133 occurs immediately after this alarm, no countermeasures are required. Restart the program directly. If the ARC-133 alarm does not occur immediately after this alarm occurs, please obtain the image backup through the abnormal status recording function ("Abnormal status recording" in the auxiliary menu) and contact the service center before performing other operations (power cutoff and jog operation) after this alarm occurs. If the abnormal status recording function cannot be used, record the situation and operation steps until the alarm occurs, obtain an image backup, and contact the service center.
