Haas Alarm 125 SHUTTLE FAULT – Haas Mill
Alarm Description
Tool shuttle not initialized at power on, Cycle Start, or spindle motion command. This means that the tool shuttle was not fully retracted to the Out position. The shuttle In/Out switches may not be functioning normally. This alarm can be caused by anything that jams the motion of the slide, a loss of power to the tool changer. Check the shuttle arm clutch for wear. Check shuttle motor for rotation. Check motor brushes and test for power at motor. Check relays K9-K12 on and fuse F1 on I/O PCB.
