3 Test Run and Program Run
3.2 Program Run
Interrupting machining
There are several ways to interrupt a program run:
• Programmed interruptions
• Machine STOP key
• Switching to PROGRAM RUN / SINGLE BLOCK
If the TNC registers an error during program run, it automatically
interrupts the machining process.
Programmed interruptions
Interruptions can be programmed directly in the part program. Program
run is interrupted at a block containing one of the following entries:
• G38
• Miscellaneous function M0, M02 or M30
• Miscellaneous function M06 (determined by the machine tool builder)
To interrupt or abort machining immediately:
The block which the TNC is currently executing is not completed.
Interrupt machining.
The ❊ symbol in the status display blinks.
Program run can be aborted with the INTERNAL STOP function.
Abort machining.
The ❊ symbol in the status display goes out.
To interrupt machining at the end of the current block:
You can interrupt the program run at the end of the current block by
switching to the PROGRAM RUN / SINGLE BLOCK mode.
Select PROGRAM RUN / SINGLE BLOCK.
