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 block scan. 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.
