FANUC Alarm SVGN-040 — Thk:%s NOT intol(expect:%s).

FANUC SVGN-040 (“Thk:%s NOT intol(expect:%s).”): The Measured part thickness deviates from the specified value more than the Under or Over thickness limit(mm). First check: Check the master position for the gun axis and make sure the tips touch at the zero position (+/- 0.1mm).

Description

The Measured part thickness deviates from the specified value more than the Under or Over thickness limit(mm). The part might be out-of-tolerance.

Remedy · Remède

Check the master position for the gun axis and make sure the tips touch at the zero position (+/- 0.1mm). Confirm that tip wear and gun sag compensation are enabled and that the compensation values are correct. Check the part or re-enter the part thickness in the pressure schedule. Alternatively, increase the Under and Over thickness limits in the Part Thickness check screen found on the Servo Gun General Setup screen. Resume the program, to retry the measurement. Perform thickness check calibration again, if the problem persists.
