15.3 Generate coded contour table (CONTDCON)
Function
With the contour preparation activated with CONTDCON, the following NC blocks that are
called are saved in a coded form in a 6-column contour table to optimize memory use. Each
contour element corresponds to one row in the contour table. When familiar with the coding
rules specified below, e.g., you can combine DIN code programs for cycles from the table
lines. The data of the output point are saved in the table line with the number 0.
Syntax
Activate contour preparation:
CONTDCON(<contour table>,<machining direction>)
Deactivate contour preparation and return to the normal execution mode:
EXECUTE(<ERROR>)
See " Deactivate contour preparation (EXECUTE) "
Significance
CONTDCON
<contour table>
<machining direction>
Note
The G codes permitted for CONTDCON in the program section to be included in the table are
more comprehensive than for CONTPRON. Further, feed rates and feed rate type are saved
for each contour section.
