[Cause]
The difference between the measured and specified thicknesses exceeds the thickness error tolerance. Check the spot program position correction status screen.
[Countermeasures]
Take the following countermeasures:
1. Check that the deviation between the panel thickness and measured thickness is not excessive.
2. Check that the panel surface is not extremely uneven.
3. Check the specified plate thickness.
4. Check the upper/lower thickness error tolerances on the spot program position correction settings screen.
5. Check that the gun mastering position is correct. If it is incorrect, thickness may not be measured correctly. If the problem continues after these countermeasures, take the following countermeasures.
1. Acquire diagnostic data for this condition. The diagnostic data acquisition procedure is described under Troubleshooting in Spot Program Touchup Function in Servo Gun Function OPERATOR’S MANUAL.
2. After this alarm occurs, before performing other operations (power-off or jogging), use the abnormal-state recording function (Abnormal state record in the auxiliary menu) to obtain an image backup and contact the service center. If abnormal-state recording cannot be used, record the conditions and operating steps leading up to the alarm, obtain an image backup and contact the service center.
