G90
Absolute positioning;
with G90 at the header,
the geometry data which
follows will be interpret-
ed relative to the active
zero point in the pro-
gram, usually with G54
or G500 or G500 + G54.

G91
Relative positioning;
with G91 you can add
an incremental value
(G91-defined data is the
relative positioning
using the present posi-
tion as the start point).
Finally you should
change the program to
absolute positioning with
G90.
G54 G55 G56 G57
G58 G59
With G500 = 0, the
offset for the work-
piece can be stored
in the G54 workpiece
offset.
G500
All absolute path
data will be relative
to this position. The
position is written in
the G500 (basic)
zero offset.
G500 + G54
With G500 unequal
to 0 and be activat-
ed, the value in
G500 will be added
to the value in G54.
