Example of simple block scan
Even after an internal stop, the control shows the number
of repetitions on the Overview tab of the status display.
After an internal stop, you would like to start in NC block 12 in the
third machining operation of LBL 1.
Enter the following data in the pop-up window:
Start-up at: N =
12
Repetitions

Procedure for multi-level block scan
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.
