Code SVGN-017: Invalid pressure coefficient
Issue Description & Safety Warning
The Fanuc R-30i Series Robot Controller has triggered a critical Invalid pressure coefficient 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: Single-segment calibration method is enabled and prm_a1 is invalid (less than 0.0001 OR greater than 100.0). Remedy: Change the calibration method to the multi-linear segment method if possible. Do this by setting the sysvars $sgsyscfg.$cal_model = 12 and $sgsyscfg.$frc2spd_cnv = 3, then perform the pressure calibration again.
