530  Test Run and Program Run
16.4 Program Run
If you are working with nested programs, you can use 
MP7680 to define whether the block scan is to begin at 
block 0 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!
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.
