A.12 List of instructions
The functions marked with an asterisk (*) are active at the start of the program in the CNC milling variant, unless otherwise
they are programmed or the machine manufacturer has preserved the default settings for the "milling" technology.
Ad dress Si gnificance
D Tool offset number
F Feedrate
F Dwell time (in block
with G4)
G G function
(preparatory func-
tion)
G g roup:
G0 Linear interpolation at rapid traverse rate
G1 * Linear interpolation at feedrate
G2 Circular interpolation in clockwise direction
(in conjunction with a third axis and
TURN=... also helix interpolation -> see
under TURN)

Va lue assignments In formation
0 ... 9, only integer, Contains compensation data
no sign for a particular tool T... ; D0
indicates no compensation for
the tool, one tool activates 1~9
numbers, that is, one tool
carries at most nine different
compensation data at the
same time.
0.001 ... 99 999.999 Path velocity of a
tool/workpiece;
unit: mm/min or mm/revolution
depending on G94 or G95
0.001 ... 99 999.999 Dwell time in seconds
Only integer, speci- The G functions are divided
fied values into G groups. Only one G
function from one group can
be written in one block.
A G function can either be
modal (until canceled by an-
other function from the same
group), or non-modal (only
effective for the block it is
written in).

interpolation), modally effec-
