5.8 Zero offset
You can activate a settable zero offset in the program you have called
with G54 to G57 and other G functions or with $P_IFRAME=...
Basic zero offset (basic frame): Is displayed like a settable WO.
You can use the programmable zero offset $P_PFRAME=.. to
program an additional work offset for geometry and special axes in
the part program you have called.
The values of the programmed work offsets are deleted with end of
program or reset.
In addition to all the offsets which define the position of the workpiece
zero point, an external zero offset can be overlaid by means of the
handwheel (DRF offset) or from the PLC.
Differential Resolver Function: An NC function which generates an
incremental zero offset in automatic mode in conjunction with an
Frame is the conventional term for a geometrical expression that
describes an arithmetic rule, such as translation or rotation.
Frames are used to describe the position of a destination coordinate
system by specifying coordinates or angles starting from the current
workpiece coordinate system.

Settable frames (G54...G599)
/PGA/ Programming Guide Advanced
A frame can consist of the following arithmetic rules:
Zero point offset, TRANS, ATRANS
Rotation, ROT, AROT
Scale, SCALE, ASCALE
Mirroring, MIRROR, AMIRROR
In the part program, all work offsets can be deselected non-modally
