SINUMERIK 840D/840Di/810D/FM-NC Programming Guide Advanced (PGA) – 04.00 Edition
14.3 Contour decoding: CONTDCON (as of SW 5.2)
Programming
CONTDCON (TABNAME,MODE)
EXECUTE (ERROR)
Explanation of the parameters
CONTDCON
Activate contour preparation
TABNAME
Name of contour table
MODE
Direction of machining, type INT
0 = Contour preparation (default) according to the contour block
sequence
EXECUTE
Terminate contour preparation
ERROR
Variable for error check-back, type INT
1 = error; 0 = no error
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 applications
(e.g. cycles). The data for the starting point are
stored in the table cell with the number 0. The G
codes permitted for CONTDCON in the program
section to be included in the table are more
comprehensive than for the CONTPRON function. In
addition, feedrates and feed type are also stored for
each contour section.
EXECUTE deactivates the contour preparation and
switches back to the normal execution mode.
Example:
N30 CONTDCON(…)
N40 G1 X… Z…
N50…
N100 EXECUTE(…)
