5. TEST OPERATION
To display the change in the position without moving the nozzle, use
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, T, and B (2nd auxiliary function)
commands, is available for checking a program together with machine

Procedure for Machine Lock and Auxiliary Function Lock
Press the machine lock switch on the operator’s panel. The nozzle does
not move but the position along each axis changes on the display as if the
nozzle 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
nozzle 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, T, and
B codes are disabled and not executed. Refer to the appropriate manual
provided by the machine tool builder for auxiliary function lock.
