2.10.4 Extending the CNC program
The sample program ("test.din") executes a circular profile. The actual target
of a CNC program is to switch on a tool while executing a program. Thus, the
sample program is extended by the corresponding M−functions M14 and
M15, which lift or lower the tool when the profile is executed. The
M−functions are programmed in a separate PLC program.
M−function Target function Programming of a separate PLC program
M14 Lower tool An output for lowering the tool is to be set. Switchover to
the next command only after one of the lower limit
switches has been activated.
M15 Lift tool An output for lifting the tool is to be set. Switchover to the
next command only after one of the upper limit switches
has been activated.
Starting point: The cursor flashes in the top right of the text editor and the
graphic area is displayed. In the control system, the program (e.g. test.din.)
is loaded.
1. Press <F2> (Open program).
2. Select the program (e.g. test.din) and press <Enter>
3. Press <F7> (Accept).
4. Add the M−functions according to the following table.
