官方故障排除步驟
Cause: Robot tip contacted lower panel surface before search motion started. Torque limit became unexpectedly-large during lower panel detection. Remedy: Confirm that distance of panel contact is not larger than search start distance. Retry spot program touchup. If robot tip contacts lower panel surface before search start distance, 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. If this problem persists after taking the above actions, perform the following actions: 1. Acquire 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.
