How do I fix and clear Mazak alarm 314?

1. Check if the chuck holds the workpiece correctly. 2. If the diameter of the workpiece currently inserted in the chuck is different from that of the previous workpiece, or if the stroke of the chuck jaw has been changed, check also if the chuck opening/closing sensor works normally when a workpiece is set in the chuck. If necessary, adjust the position. Clearing procedure: Fix cause → press RESET.
