Use the cursor keys to select the workpiece
in the workpiece overview and then
press softkey "Selection".
· If only one main program (MPF) exists in this directory, it is
automatically selected for execution. If the directory contains
several main programs, the main program with the same name as
the directory is automatically selected for execution (e.g. if you
select workpiece SHAFT.WPD main program SHAFT.MPF is
automatically selected).
The program name is output along with workpiece information in
the "Program name" window at the top right.
You can start the part program you have selected by pressing the
"NC Start" key.
· If an INI file of the same name exists (e.g. SHAFT.INI), it will be
executed once at first part program start after select the part
program. Machine data 11280 $MN_WPD_INI_MODE controls
which additional INI files are executed.
When you select workpiece directory SHAFT.WPD you implicitly select
program SHAFT.
If a .JOB file with the same name is stored in the
workpiece directory, it is executed immediately.
See also Chapter "Job list" and "Sequence of operations" "Executing
job list".
If the call path for a subprogram (or an initialization file) is not explicitly
specified in the part program, a fixed search strategy is applied to find
the called program.
Case 1: When a subprogram is called by
name with specification of the data type ("identifier" or "extension"),
e.g. SHAFT1.MPF,
the system searches through the directories in the following
sequence:
1. Current directory / name.type
2. /SPF.DIR / name.type
3. /CUS.DIR / name.type
4. /CMA.DIR / name.type
5. /CST.DIR / name.type
