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
– Shift direction for boring cycles (G76 and G87) (for Power Mate i–D
only)
Mirror image check signals indicate whether mirror image is applied to
each axis. System variable #3007 contains the same information (refer
to II–13.2 in the operator’s manual).
[Classification] Input signal
[Function] Apply mirror image to the specified axes.
[Operation] Apply mirror image to those axes for which the signals are 1.

A number appended to a signal represents the controlled axis number.
1 ..... Applies mirror image to the 1st axis.
2 ..... Applies mirror image to the 2nd axis.
3 ..... Applies mirror image to the 3rd axis.
