问题描述与安全警告
Fanuc R-30i Series Robot Controller 触发了严重的 Pressure is not invertible. 警报。需要由合格的操作员或维修技师立即处理，以防止在制造周期中对设备造成二次损坏或导致零件报废。在接触电气控制箱之前，请务必确保遵循标准安全和停机挂牌 (LOTO) 程序。
官方故障排除步骤
Cause: The specified pressure cannot be used, it does not lie on the calibration curve (2nd order). Remedy: Change the calibration method to the multi-linear segment method if possible. Do this by setting the system variables $sgsyscfg.$cal_model = 12 and $sgsyscfg.$frc2spd_cnv = 3, then perform the pressure calibration again. Alternatively, perform pressure calibration again, or reduce max pressure.
