13. Program Support Functions
(16) Coordinate read variable
When reading the workpiece coordinate system/skip coordinate system during the
3-dimensional coordinate system conversion modal, local coordinate system and G68.1
program coordinate system can be switched with the parameter "#1563 3Dcdrc".
(17) Manual operation
Manual operation in the 3-dimensional coordinate conversion modal will not execute the
3-dimensional conversion. Manual operation will be executed in the machine coordinate
system. Also, when the manual ABS is OFF, G68.1 program coordinate system will move as
much as the manual interruption or manual feed amount.
(18) Workpiece coordinate display
Whether the workpiece coordinate position in the 3-dimensional coordinate conversion modal
to be displayed in the workpiece coordinate system or in the G68.1 program coordinate system
can be switched with the parameter "#1561 3Dcdc". In the same manner, absolute value can
be displayed on the special display.
(Note) 1um of display deviation may occur during the 3-dimensional coordinate conversion;
(19) Remaining command display
Whether the remaining commands in the 3-dimensional coordinate conversion modal to be
displayed in the workpiece coordinate system or in the G68.1 program coordinate system can
be switched with the parameter "#1562 3Dremc".
(Note) 1um of display deviation may occur during the 3-dimensional coordinate conversion;
(20) Others
G41, G42, and the fixed cycle command G73 to G89 have to be nested inside the G68.1/G69.1
commands.
For the block next to G68.1, a movement command in the G90 (Absolute value command)
mode has to be issued.
(Example)
• G00 command during 3-dimensional coordinate conversion modal is the interpolation type
regardless of settings of the basic parameter "#1086 G0Intp (G00 non-interpolation)"
• Origin zero cannot be executed during the 3-dimensional coordinate conversion modal.
