Haas Alarm: 115 (L) TURRET ROTATE FAULT – Tool motor not in position. During a tool changer operation the tool turret failed to start moving or failed to stop at the right position. Parameters 62 and 63 can adjust the time-out times. This alarm can be caused by anything that jams the rotation of the turret. A loss of power to the tool changer can also cause this, so check CB5, relays 1-8, 2-3, and 2-4.
