Programming example
G500:
All absolute path data corresponds to
the current position. The position val-
ues are written in the G500 (basic) zero
offset.

G54 to G59:
With G500 = 0, the offset for the work-
piece can be stored in the workpiece
offsets G54 to G59.

G500 + G54:
With G500 ≠ 0 activated, the value in
G500 is added to the value in G54.

G90:
With G90 (absolute positioning) at the
program start, the geometrical data
refers to the zero of the coordinate
system currently active in the program,
usually with G54, G500, or G500 +
G54.

G91:
With G91 (incremental positioning), you
can add numerical value of path infor-
mation (the incremental positioning with
the current axis position as the start
point) in the program. Subsequently,
switch to absolute positioning with G90.
