Reference point offset
Selection
G92 <axis designation> <offset> ...
G92 enables a reference point offset by a freely programmable value in the specified axes; - also called additional zero offset. Depending on the set G90/G91, the currently programmed reference point offset is set absolutely or is added to the previous one.

Effectiveness
Active up to programming of the next reference point offset or the end of the program.
A new offset does not take effect until programmed in the absolute measurement system (G90).
