Interrupt, stop or abort machining
There are several ways to stop a program run:
Interrupt the program run with e.g. the miscellaneous function
M0
Interrupt the program run e.g. with the miscellaneous function
M0
Stop the program run e.g. with the NC STOP key in conjunction
with the INTERNAL STOP soft keyINTERNAL STOP
Terminate the program run e.g. with the miscellaneous
functions M2 or M30
The control shows the current status of the program run in the
status display.
Further Information: "General status display", page 84
The difference between an interrupted (terminated) program run
and a stopped run is that an interrupted run allows the user to carry
out the following actions:
Select operating mode
Check Q parameters and change these if necessary using the Q
INFO function
Change setting for the optional programmed interruption with
M1
Change setting for the programmed skipping of NC blocks with
/
If the control registers an important error during a
program run, it automatically stops the program run.
Example: Cycle call with stationary spindle
