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.
If the working plane is tilted, you can use the 3-D ON/OFF
soft key to define whether the TNC is to return to the
contour in a tilted or in a non-tilted coordinate system.
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.
If you execute mid-program startup in a program
containing M128, the TNC performs compensating
movements as necessary. The compensating movements
are superposed over the approach movement.
