. Mirror image external input function

(a) Overview

In addition to the conventional mirror image
function, the mirror image execution mode can also
be set when power is turned on, or reset, by
setting the corresponding parameter.

When the

mode is the mirror image execution mode (power on
or reset, ) the parameter can be set to select the
command mirror image at the G28 intermediate point
or not.

(b) How to use the function

(i) Upon power ON or upon reset

#6005,

O: M94 mode (mirror image off)
1: M95 mode (mirror image on)

(ii) Upon power ON, when it is M95 mode (#6005,

i s “ l . ” )

#6005,

O: Commands mirror image at the

intermediate point

1: Does not command mirror image at

the G28 intermediate point

Note : The specifications are the same as the

conventional specifications, when #6005,

is “O. ”

Therefore, turn off mirror image by M94, when
commanding G28, or G29 under this mode.

Note:

When power is applied or the control is

reset, the control is in the state of M code
marked

In the G41 or G42 tool radius compensation mode,
when M96 is given, the tool moves along a circular
path around a corner with an angle of

or larger.

In the M97 mode, the tool does not move along a
circular path at the corner, but moves along two
intersecting straight lines intersecting at a calculated
intersecting point shifted from the programmed
contour by the tool radius.
