Code SVGN-270: Too large torque limit.(Upper)

Cause: Gun tip contacted upper panel surface before search motion started. Torque limit became unexpectedly-large during upper panel detection step1. Remedy: Confirm that distance of gun panel contact is not larger than search distance. Retry spot program touchup. If gun tip contacts upper panel surface before search start distance, confirm that: 1. no obstruction exists between guntip and panel. If the above item is OK, confirm that: 1. nominal thickness in pressure schedule is correct. 4.ERROR CODES B-83124EN-6/02 2. OverThickness tolerance (on gun teach setup screen) is large enough. If the above items are OK, confirm that: 1. Max allowable Pos error (on gun teach setup screen) is large enough. If the above item is NG, the position error is made less than maximum allowable position error in the following ways. 1. Touch up correct position using jog or point touchup(not program touchup). 2. Increase maximum allowable position error on gun teach setup screen. If this problem persists after taking the above actions, perform the following actions: 1. Acquire the diagnostic data. See the procedure for diagnostic data collection at Chapter “20.19 Troubleshooting” in operator’s manual for Servo Gun Function.. 2. Contact your local FANUC representative.
