Procedure for multi-level mid-program startup
If you, for example, start in a subprogram that is called several
times by the main program, then use the multi-level mid-program
startup. For this purpose, jump in the main program to the desired
subprogram call. With the
CONTINUE BLOCK SCAN
function, you
can jump further from this position.
Operating notes:
The control only displays the dialogs required by the
process in the pop-up window.
You can also continue the
BLOCK SCAN
without
restoring the machine status and the axis position
of the first startup point. For this, press the
CONTINUE BLOCK SCAN
soft key before confirming
the restoration with the
NC-Start
key.

NC block:

key
