Calling any program as a subprogram
NOTICE
Danger of collision!
The control does not automatically check whether collisions
can occur between the tool and the workpiece. If coordinate
transformations are not specifically reset in called NC programs,
then these transformation are likewise effective for the calling
NC program. Danger of collision during machining!
Reset coordinate transformations used in the same NC
program
Check the machining sequence using a graphic simulation if
required
Programming notes:
If the program you want to call is located in the same
directory as the program you are calling it from, then
you only need to enter the program name.
If the program called is not located in the same
directory as the calling program, you must enter
the complete path, for example
TNC:\ZW35\HERE
\PGM1.H
Alternatively, you can program relative paths:
Starting from the folder of the calling program one
folder level up
..\PGM1.H
Starting from the folder of the calling program one
folder level down
DOWN\PGM1.H
Starting from the folder of the calling program one
folder level up and in one other folder
..\THERE
\PGM3.H
If you want to call a DIN/ISO program, enter the file
type .I after the program name.
You can also call a program with Cycle
12 PGM CALL
.
You can call any program by also using the function
Select the cycle
(
SEL CYCLE
).
As a rule, Q parameters are effective globally with
a
PGM CALL
. So please note that changes to Q
parameters in the called program also influence the
calling program.
