Plane selection system
In Table 1,
I is the horizontal axis for the G17 plane or the vertical axis for the G18 plane
J is the vertical axis for the G17 plane or the horizontal axis for the G19 plane
K is the horizontal axis for the G18 plane or the vertical axis for the G19 plane
In other words,
G17 ..... IJ plane
G18 ..... KI plane
G19 ..... JK plane
(1) The axis address commanded in the same block as the plane selection (G17, G18, G19)
determines which basic axis or parallel axis is used for the plane selection.
For the parameter registration example in Table 1.
G17X__Y__ ;
G18X__V__ ;
G18U__V__ ;
G19Y__Z__ ;
G19Y__V__ ;
(2) The plane will not changeover at a block where a plane selection G code (G17, G18, G19) is
not commanded.
G17X__Y__ ;
Y__Z__ ;
(3) I f the axis address is omitted in the block where the plane selection G code (G17, G18, G19)
is commanded, it will be viewed as though the basic three axes address has been omitted.
For the parameter registration example in Table 1.
G17 ;
G17U__ ;
G18U__ ;
G18V__ ;
G19Y__ ;
G19V__ ;
(4) The axis command that does not exist in the plane determined by the plane selection G code
(G17, G18, G19) is irrelevant to the plane selection.
For the parameter registration example in Table 1.
G17U__Z__ ;
(5) If the above is commanded, the UY plane will be selected, and Z will move regardless of the
plane.
If the basic axis and parallel axis are commanded in duplicate in the same block as the plane
selection G code (G17, G18, G19), the plane will be determined in the priority order of basic
axis and parallel axis.
For the parameter registration example in Table 1.
G17U__Y__W__-;
If the above is commanded, the UY plane will be selected, and W will move regardless of the
plane.
(Note 1) The plane set with parameter "#1025 I_plane" will be selected when the power is
turned ON or reset.
