5.4 Coordinate preset (G92)
Coordinate presetting is done with function G92 and it may be applied onto any axis of the
machine.
When presetting coordinates, the CNC interprets that the axis coordinates programmed after
function G92 define the current position of the axes. The rest of the axes that have not been
defined with G92 are not affected by the preset.
Considerations
A coordinate preset, by itself, does not cause any axis movement.
When homing an axis in JOG mode, the preset for that axis is canceled.
Function properties
G92 is modal, the preset values remain active until the preset is canceled (with another
preset, a zero offset or with G53).
On power-up, the CNC assumes the coordinate preset that was active when the CNC was
turned off. On the other hand, the coordinate preset is neither affected by functions M02 and
M30 nor by RESETTING the CNC.
