Procedure for multi-level mid-program startup
If you start in a subprogram that is called several times by the main
program, use the multi-level mid-program startup. For this purpose,
jump in the main program to the desired subprogram call. Use
the function

to jump further from this
position.
The control only displays the dialogs required by the

restoring the machine status and the axis positions
of the first startup point. For this purpose press the
