代碼 256: Current Tool Unknown
問題描述與安全警告
Haas VF-Series CNC 觸發了嚴重的 Current Tool Unknown 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
Current tool information has been lost. This is most likely due to re-initialization. It is likely that the next commanded tool change will result in a collision between the spindle and a tool in a pocket. To eliminate the possibility of a crash, perform Tool Changer Restore. Do not use Power Up/Restart as this will cause the machine to try to return a tool to the carousel.
