问题描述与安全警告
Fanuc R-30i Series Robot Controller 触发了严重的 Bad Pressure (EP=*) %s 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: An invalid binary equalization pressure was programmed in the teach pendant program. Remedy: In the teach pendant program, check the equalization pressure spot welding instruction EP= value. Note: The smallest valve pressure allowed is 0. For digital weld controllers, the largest pressure number allowed depends on the width of the Equalization Pressure group output. If this GOUT is 4 I/O points wide, then the maximum pressure is 15. If the GOUT is 5 I/O points wide, then the maximum pressure is 31. For serial weld controllers, the maximum pressure is 15. Re-program the EP= value in the teach pendant program.
