代碼 SVGN-274: Too low speed threshold.

Cause: Threshold to detect panel contact became unexpectedly-low. Remedy: If gun tip contacted panel surface at start position, confirm that no obstruction exists between guntip and panel. If obstruction exists, remove it and retry spot program touchup or avoid it and touch up correct position using jog or point touchup(not program touchup). If robot tip contacted lower panel surface at start position, increase start distance(SD) for robot tip and/or lower panel detection distance. Refer to Chapter “20.6 LOWER PANEL DETECTION DISTANCE CLAMP” or “20.13 SPTCH_RSD INSTRUCTION” in operator’s manual for Servo Gun Function for more information about the lower panel detection distance. Retry spot program touchup. 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.
