Additional notes
Preconditions for the call
Before CONTDCON is called
• a starting point must be approached which
permits collision-free machining,
• tool edge radius compensation with G40 must be
deactivated.
Permitted traversing commands, coordinate
system
The following G groups and specified commands are
permissible for 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 functions spline, polynomial, thread 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 produced an alarm.
