Code SVGN-114: Tip wear misdetection.(FIX).
Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical Tip wear misdetection.(FIX). alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Cause: The moving tip did not touch the fixture during the second step of tip wear measurement due to an increase in gun friction, or the fixture and/or robot master position has changed since tip wear was initialized. Remedy: If the moving tip is not pressing into the fixture when the alarm occurs, the fixture touch load (i.e. pressing force) was reached without actually touching the fixture. This usually happens because the gun friction has increased since the tip wear setup program was run. Increase the Margin of Load item in the Tip Wear Detection Screen to overcome the increase in friction. Doing this can affect the tip wear measurement, so the tip wear setup procedure should be performed again. Autotune the gun again and/or inspect the gun for the cause of the friction increase. If the moving tip is pressing into the fixture when the alarm occurs then the fixture position has moved relative to the robot master position, the robot master data has changed, or the points in the program TW_MV2PT.tp have changed. Perform the tip wear setup procedure again.
