Reference point offset (G92)

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.

Notice

"Non-modal"

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

Programing Example

prg_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)

Notice

notice

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).
