 To go to the first block of the current program to start a block scan,
enter GOTO “0”.
 To select block scan, press the BLOCK SCAN soft key,
or
 Start-up at N: Enter the block number N at which the
block scan should end.
 Program: Enter the name of the program containing
block N.
 Repetitions: If block N is located in a program section
repeat, enter the number of repetitions to be
calculated in the block scan.
 To start the block scan, press the machine START
button.
 Contour approach (see following section).
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).
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.
