Alarm: 256 CURRENT TOOL UNKNOWN – Haas Mill
Haas Alarm Description:
Current tool information has been lost. This is most likely due to reinitialization. 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,this will cause the machine to try to return a tool to the carousel.
