代碼 TMAT-002: Sensor failed during search
問題描述與安全警告
Fanuc R-30i Series Robot Controller 觸發了嚴重的 Sensor failed during search 警報。需要由合格的操作員或維修技師立即處理，以防止在製造週期中對設備造成二次損壞或導致零件報廢。在接觸電氣控制箱之前，請務必確保遵循標準安全和停機掛牌 (LOTO) 程序。
官方故障排除步驟
Cause: Cause1: The TorchMate sensor circuit indicates the wire is in contact with the touch plate before the search move (too much stickout-the search start distance is too small.) Cause2: An electrical short exists in the touch circuit (for example, some circuits require a blocking diode on the power supply.) Remedy: Remedy1: Decrease the stickout, increase the search start distance, or replace the bent torch. Remedy2: Contact the supplier of your weld equipment regarding the touch circuit requirements and auxiliary wiring (if needed.)
