5) Positioning the machine coordinate system such as G28,G30, or G53 is not subjected to
coordinate conversion.
6) When the three-dimensional coordinate conversion function is used, linear rapid traverse
must be specified by setting parameter LPR of parameter No.1401 to I.
7) In the G68.1 or G69.1 block, another G code must not be specified. The G68.1 block must
contain I,J, and K.
8) Three-dimensional and two-dimensional coordinate conversion use identical G codes
(G68.1 and G69.1). A G code specified with I,J, and K is processed as the command for
three-dimensional coordinate conversion. A G code not specified with I,J, and K is
processed as the command for two-dimensional coordinate conversion.
9) External mirror image (mirror image by the mirror image signal or setting) cannot be
specified.
10) To display the absolute position when three-dimensional coordinate conversion is executed,
set bit 4 to 7 of parameter DRL,DRC,DAL, and DAC No3104 to 0.
11) The drilling cycle specified by G41 ,G42 must be embedded in the G68.1 cycle. The entire
canned cycle must be included in the routine determined by G68.1 and G69.1.
See the example below:
G68.1 X100. YIOO. ZIOO. IO. JO. Kl. R45. ;

12) When using the tool offset, nest the commands for the tool offset between the commands
for three-dimensional coordinate conversion.
