1.2.6 Mirror Image
General
Mirror image can be applied to each axis, either by signals or by
parameters (setting input is acceptable). All movement directions are
reversed during automatic operation along axes to which a mirror
image is applied.
However, the following directions are not reversed:
- Direction of manual operation and direction of movement, from
the intermediate position to the reference position during
automatic reference position return
- Positioning in a machine coordinate system (G53)
- Approach direction for single direction positioning (G60) and
shift direction for boring cycles (G76 and G87)
Mirror image check signals indicate whether mirror image is applied to
each axis. System variable #3007 contains the same information (refer
to the Sec.II-17.2 in Operator's Manual (Programming)).

[Classification] Input signal
[Function] Apply mirror image to the specified axes.
[Operation] Apply mirror image to those axes for which the signals are 1. These
signals are provided for the controlled axes on a one-to-one basis. A
number appended to a signal represents the controlled axis number.
MIx
x : 1 ..... Applies mirror image to the 1st axis.
2 ..... Applies mirror image to the 2nd axis.
3 ..... Applies mirror image to the 3rd axis.

The mirror image signal can be turned to "1" in the following cases:
(1) During offset cancel;
(2) When the CNC is in the automatic operation stop state and not in
the feed hold state.
