12.3 PROGRAM CALL (Cycle 12, DIN/ISO:
G39)
Cycle function
Routines that you have programmed (such as special drilling cycles
or geometrical modules) can be written as main programs. These
can then be called like fixed cycles.
Please note while programming:
The program you are calling must be stored on the
hard disk of your TNC.
If the program you are defining to be a cycle is
located in the same directory as the program you
are calling it from, you need only enter the program
name.
If the program you are defining to be a cycle is not
located in the same directory as the program you are
calling it from, you must enter the complete path, for
example
TNC:\KLAR35\FK1\50.H.
If you want to define a DIN/ISO program to be a
cycle, enter the file type .I behind the program name.
As a rule, Q parameters are globally effective when
called with Cycle 12. So please note that changes
to Q parameters in the called program can also
influence the calling program.
Cycle parameters
Program name: Enter the name of the program
you want to call and, if necessary, the directory it is
located in or
Activate the file select dialog with the SELECT soft
key and select the program to be called
Call the program with:
CYCL CALL (separate block) or
M99 (blockwise) or
M89 (executed after every positioning block)
Designate program 50 as a cycle and
call it with M99
