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.
