The G92.2 command cancels the following offsets:

G92 work coordinate system offset
{SET ZERO} offset
Jog offset

It will not cancel an external offset (see section 11.3), reset the current
work coordinate system (G54-G59.3) or cancel a G52 offset.

The G92.2 block must be programmed with no axis words. Axis words in
a G92.2 block will generate an error. When the G92.2 block is executed all
G92, {SET ZERO}, and Jog offsets are canceled on all axes. It is not
possible to cancel the offsets on only one or more of the axes.

No axis motion takes place during execution of a G92.2 block. Axes
remain at their last programmed position while the work coordinate system
is adjusted to remove these offsets.
