Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical Tip wear down misdetection. 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 tips did not touch during the 1st step of tip wear measurement due to an increase in gun friction or the tips touched but they are now longer than the reference tips by an amount greater than the Mis-Detect Toler.(mm) 4.ERROR CODES B-83124EN-6/02 Remedy: If the tips are not fully closed when the alarm occurs, then the re-master operation failed during tip wear measurement. This usually happens because the gun friction has increased since the gun was last Autotuned. Autotune the gun again and/or inspect the cause of the friction increase. After this is complete, put new tips on the gun and perform the tip wear setup procedure again. If the tips are closed when the alarm occurs, then the tips are longer than allowed. The tips measured during tip wear setup are the reference tips. New tips can only be longer than the reference tips by an amount equal to the Mis-Detect Toler.(mm) specified in the Tip Wear Detection screen (within the Servo Gun SETUP screen). Either increase the Mis-Detect Toler.(mm) or replace the tips with shorter tips. If the tips seem to be the correct length, then perform the tip wear setup procedure again to establish new reference tips.
