14-8 Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
Always in last line of table:
9) Predecessor: Line n is the contour table start (backwards)
10) Successor: Line n contains the contour start (backwards)
Permitted traversing commands, coordinate system
The following G commands can be used for the contour programming:
G group 1: G0, G1, G2, G3
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
CONTPRON 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.
Terminate contour preparation
When you call the predefined subroutine EXECUTE (variable), contour preparation is
terminated and the system switches back to normal execution when the contour has been
described. The variable then indicates:
1 = error
0 = no error (the contour could be prepared without error).
Relief cut elements
The contour description for the individual relief cut elements can be performed either in a
subroutine or in individual blocks.
Stock removal independent of the programmed contour direction
The CONTPRON contour preparation has been expanded so that after being called, the
contour table is available irrespective of the programmed direction.

Function
The blocks executed after CONTPRON describe the contour to be decoded. The blocks are
not processed but stored, memory-optimized, in a 6-column contour table. Each contour
element corresponds to one row in the contour table. When familiar with the coding rules
specified below, you can combine DIN code programs from the tables to produce
