4.4.1 Incremental zero offset (G158)
When applying an incremental zero offset, the CNC adds it to the
absolute zero offset active at a time.
Programming
Incremental zero offset are defined by program using function G158
followed by the values of the zero offset to be applied on each axis.
To cancel the incremental zero offset, program function G158 without
axes in the block. To only cancel the incremental zero offset on
particular axes, program an incremental offset of "0" on each of those
axes.
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.
