If you are working with nested programs, you can use

MP7680 to define whether the block scan is to begin at

block0 of the main program or at block 0 of the last

interrupted program.
With the 3-D ROT soft key you can switch the coordinate

system between tilted and non-tilted in order to move to

the start-up position.
If you want to use the block scan feature in a pallet table,

select the program in which a mid-program startup is to be

performed from the pallet table by using the arrow keys.

Then press the RESTORE POS AT N soft key.
The TNC skips all touch probe cycles in a mid-program

startup. Result parameters that are written to from these

cycles might therefore remain empty.
The M142/M143 and M120 functions are not allowed during a

mid-program startup.
Before beginning the mid-program start-up, the TNC

deletes traverse movements that you performed during

the program with M118 (handwheel superimpositioning).

Danger of collision!

For safety reasons always check the distance to go to the

startup position after a block scan!
If you perform a mid-program startup in a program

containing M128, then the TNC performs any

compensation movements necessary. The compensation

movements are superimposed over the approach

movement!
You may not use mid-program startup in combination with

tool-oriented pallet machining. Re-entry is only possible on

a workpiece that has not been machined yet.
