5. TEST OPERATION
To display the change in the position without moving the tool, use
All–axis machine lock, which stops the movement along all axes. In
addition, auxiliary function lock, which disables M, S, and T commands,
is available for checking a program together with machine lock.
The tool does not move but the
position along each axis changes
on the display.

Procedure for Machine Lock and Auxiliary Function Lock
Refer to the appropriate manual provided by the machine tool builder for
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
T codes are disabled and not executed. Refer to the appropriate manual
provided by the machine tool builder for auxiliary function lock.
M, S, and T commands are executed in the machine lock state.
When a G27, G28, or G30 command is issued in the machine lock state,
the command is accepted but the tool does not move to the reference
position and the reference position return LED does not go on.
M00, M01, M02, M30, M98, and M99 commands are executed even in
the auxiliary function lock state.
Moreover, M codes for calling subprograms (parameter Nos.6071 to
6079) and M codes for calling custom macros (parameter Nos.6080 to
6089) are executed.
