There are two types of machine lock: all–axis machine lock, which stops
the movement along all axes, and specified–axis machine lock, which
stops the movement along specified axes only. In addition, auxiliary

tool is to be stopped. Refer to the appropriate manual provided by the
machine tool builder for machine lock.
The positional relationship between the workpiece
coordinates and machine coordinates may differ before and
after automatic operation using machine lock. In such a
case, specify the workpiece coordinate system by using a
coordinate setting command or by performing manual
reference position return.
Press the auxiliary function lock switch on the operator’s panel. M, S, and
