- The dimension can be speci-
fied for the end or center point
of a certain axis, irrespective
of G91.
1 ... 200, integer Acceleration override for an
axis or spindle; specified as a
percentage
- It is also possible to specify
the dimensions for the end
point of a rotary axis with
ACP(...) irrespective of
G90/G91; also applies to
spindle positioning
- It is also possible to specify
the dimensions for the end
point of a rotary axis with
ACN(...) irrespective of
G90/G91; also applies to
spindle positioning
±0.00001 ... Specified in degrees; one
359.99999 possibility of specifying a
straight line when using G0 or
G1 if only one end-point coor-
dinate of the plane is known or
if the complete end point is
known with contour ranging
over several blocks
0 ... ±359.99999 Specification in degrees, trav-
ersing in polar coordinates,
definition of the pole; in addi-
tion: Polar radius RP
0.00001 ... Specified in degrees; one
359.99999 possibility of defining the circle
when using G2/G3
- Special form of the cycle call;
no parameter transfer; the
