Coordinate preset (G92)

G92 Coordinate preset (non-modal)

G92 allows a programmable additional zero offset in the given axes by an optionally programmable value. Depending upon the G90/G91-setting, the currently programmed offset is set absolutely or added to the existing one.

"Non-modal" only corresponds to G92; the coordinate preset itself is, of course, valid until the programming of another G92.

Programming example

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 coordinate preset to 0 ) 

Change of coordinate preset in the G91-mode: Programming of: N10 G92 X10 Y20 N20 G00 X0 G91 must not cause any movement in the X-axis (corresponding to relative movement 0). Thus, coordinate preset has effect only for an axis when the next traverse information is programmed in absolute mode (G90).
