Explanation of column contents
Line 0 Coding for the starting point:
Lines 1-n:
Permitted traversing commands, coordinate system
The following G groups and G commands can be used for the contour programming:
G group 1:
G group 10:
G group 11:
G group 13:
G group 14:
G group 15:
also corner and chamfer.
Circular-path programming is possible via CIP and CT.
The Spline, Polynomial, Thread functions produce errors.
It is not permitted to change the coordinate system by activating a frame between
CONDCRON and EXECUTE. The same applies to a change between G70 and G71/ G700
and G710.
Changing the geometry axes with GEOAX while preparing the contour table produces an
alarm.
