2.11 Subroutine call through NC language replacement
2.11.1 Generally for replacement of NC language commands
Function
NC functions can be adjusted easily to changed environment conditions if they are replaced
by subroutines. More complex tasks can be implemented there without having to change the
programming of the part program. In general, the following are possible:
• Auxiliary functions M, T and D/DL can be replaced with subroutines:
• Spindle-related functions are defined for synchronous spindle coupling:
For further information, refer to Chapter
"M-Function Replacement" and "Replacement of Tool Programming" as well as
"Spindle-related Replacements in Synchronous Mode".
Replacement of M, T, D/DL auxiliary functions
The replacement of M, T or D/DL auxiliary functions can be configured through the following
machine data:
