File and program management
2.1 Program memory
Creating a workpiece directory with a path name ($PATH=...)
The destination path $PATH=... is specified within the second line of the file. The file is then
stored at the specified path.
Example:
Program code
%_N_SHAFT_MPF
;$PATH=/_N_WKS_DIR/_N_SHAFT_WPD
N40 G0 X... Z...
...
M2
File _N_WELLE_MPF is stored in directory /_N_WKS_DIR/_N_WELLE_WPD.
Creating a workpiece directory without a path name
If the path name is missing, files with the _SPF extension are stored in directory
/_N_SPF_DIR, files with the _INI extension are stored in the RAM and all other files are
stored in directory/_N_MPF_DIR.
Example:
Program code
%_N_SHAFT_SPF
...
M17
File _N_WELLE_SPF is stored in directory /_N_SPF_DIR.
Select workpiece for machining
A workpiece directory can be selected for execution in a channel. If a main program with the
same name or only a single main program (_MPF) is stored in this directory, this is
automatically selected for execution.
