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.
