Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical Phase matching timeout (F:%d^1) 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: Insertion time exceeded the upper limit during the phase match insertion. Remedy: 1. Increase the value of 'Phase Match Rot Vel' in Basic Data. 2. Increase the value of 'Phase Match Torque' in Performance Data. 3. Phase match insertion works well in a range of about 20 degrees. Make sure that the phases of the workpiece and the object match in this rotation. 4. Make sure that the insertion clearance is large enough.
