Reference point offset (G92)

Syntax:

G92

Reference point offset

non-modal

G92 allows a programmable reference point offset in the given axes by a freely programmable value in [mm, inch] (additive reference point offset). Depending on the G90/G91 setting, the currently programmed reference point offset is set absolutely or added to the existing one.

"Non-modal"

…only applies to G92; of course, reference point offset itself only applies up to the new G92 programming

Programming Example

Reference point offset (G92)

N10 G90               (Absolute dimensional specification)
N20 G92 X10 Z30       (Displaces the programmed and the absolute)
.                     (coordinates by 10 in X, 30 in Z.)
.                     
.                     
Nnn G92 X0 Z0         (Reset of reference point offset)

In addition, the following applies to selecting a reference point offset in G91 mode:

The programming of...

N10 G92 X10 Y20

N20 G0 X0 G91

... may not cause any movement of the X axis (corresponds to relative movement about 0). The reference point offset is then only effective for an axis when the next motion information is programmed in absolute mode (G90).
