Zero offsets (G54-G59/G159)
·91·
(REF: 1709)
Only one incremental zero may be active at a time for each axis; therefore, applying an
incremental zero offset on an axis cancels the one that was active on that axis. The offsets
on the rest of the axes are not affected.
The incremental zero offset is not canceled after applying a new absolute zero offset (G54-
G59 or G159).
Considerations
An incremental zero offset, by itself, does not cause any axis movement.
When homing an axis in JOG mode, the incremental zero offset for that axis is canceled.
Function properties
Function G158 is modal.
On power-up, the CNC assumes the incremental zero offset that was active when the CNC
was turned off. On the other hand, the incremental zero offset is neither affected by functions
M02 and M30 nor by RESETTING the CNC.
