5.1 MACHINE LOCK AND AUXILIARY FUNCTION LOCK
To display the change in the position without moving the tool, use
machine lock.
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 function lock, which disables M, S, and T commands, is
available for checking a program together with machine lock.

Procedure for Machine Lock and Auxiliary Function Lock
- Machine Lock
Press the machine lock switch on the operator’s panel. The tool does
not move but the position along each axis changes on the display as if
the tool were moving. Some machines have a machine lock switch for
each axis. On such machines, press the machine lock switches for the
axes along which the tool is to be stopped. Refer to the appropriate
manual provided by the machine tool builder for machine lock.
- Auxiliary Function Lock
Press the auxiliary function lock switch on the operator’s panel. M, S,
T and B codes are disabled and not executed. Refer to the appropriate
manual provided by the machine tool builder for auxiliary function
lock.
