Resuming program run after an interruption

If you cancel a program with INTERNAL STOP, you
have to start the program with the

RESTORE POS. AT

N function or with GOTO "0".
If a program run is interrupted during a fixed cycle,
the program must be resumed from the beginning
of the cycle. This means that some machining
operations will be repeated.

If you interrupt a program run during execution of a subprogram or
program section repeat, use the

RESTORE POS AT N function to

return to the position at which the program run was interrupted.
