Official Troubleshooting Steps
Cause: Gun touchup function has modified position of spot point. This message is provided for informational purposes only, it is not a fault/problem. Note: SVGN-183 is not posted during program touchup. Remedy: The 4 parameters in SVGN-183 p1/p2/p3/ p4 provide details about the modified point. P1: Program name of the modified point. P2: Program line number of the modified point p3: Corrected value is the difference between new recorded position and old recorded position. Note: robot close direction is positive polarity, so if new position is shifted in robot open direction (relative to old position) corrected value will be negative. p4: Thickness value is actual thickness measured during thickness check.
