8 To go to the first block of the current program to start a block scan,
enter GOTO “0”.
8 To select block scan, press the BLOCK SCAN soft key,
or
8 Start-up at N: Enter the block number N at which the
block scan should end.
8 Program: Enter the name of the program containing
block N.
8 Repetitions: If block N is located in a program section
repeat, enter the number of repetitions to be
calculated in the block scan.
8 To start the block scan, press the machine START
button.
8 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 functions are not allowed during a mid-
program startup.
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.
