问题描述与安全警告
Fanuc R-30i Series Robot Controller 触发了严重的 GunA, GunB contact speed is different 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 contact speed used in this Pressure Schedule is different for Gun A and Gun B - but contact speed must match to achieve synchronized contact with the part. Remedy: Set the contact speed of the Pressure Schedule to the same value for both guns. This is done by adjusting the pressure calibration data which determines the contact speed. The Speed at a given Pressure must be the same for both guns. It is recommended to use matching Pressure and Speed values for each calibration point for both guns. Then, find the unique torque% required to achieve the pressure for each gun. OR, just set the contact speed for all points in the Pressure Calibration table for both guns to the same value.
