Parameters Description normal/XY
(without A/B axis)
Unit
Z0 Height of workpiece (abs. or inc.) mm
X0 X position of pitch circle center point (abs. or inc.) mm
Y0 Y position of pitch circle center point (abs. or inc.) mm
α0
Basic angle of rotation; angle of 1st position in relation to X axis. Degr.
α1
dvance angle; after the first hole has been drilled, all further positions are
advanced by this angle.
Positive angle: Further positions are rotated counterclockwise.
Negative angle: Further positions are rotated clockwise.
Degr.
R Radius of pitch circle mm
N Number of positions (holes) on the pitch circle
FP Feed for positioning on a circular path. mm/min
Positioning Linear: Next position is approached linearly at rapid traverse.
Circular: Next position is approached at the programmed feedrate (FP) along a
circular path.
Parameters Description XA

X0 Reference position (abs. or inc.) mm
0 Start angle (abs.)
ngle of 1st position relative to X axis.
Degr.
1
dvance angle (abs.)
after the first hole has been drilled, all further positions are advanced by this angle.
Positive angle: Further positions are rotated counterclockwise.
Negative angle: Further positions are rotated clockwise.
Degr.
N Number of positions on pitch circle
