Mid-program startup must not begin in a subprogram.
All necessary programs, tables and pallet files must be
selected in a program run mode of operation (status M).
If the program contains a programmed interruption
before the startup block, the block scan is interrupted.
Press the machine START button to continue the block
scan.
After a block scan, return the tool to the calculated
position with RESTORE POSITION.
If you are working with nested programs, you can use
machine parameter 7680 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.
To go to the first block of the current program to start a block
scan, enter GOTO "0" .
To select mid-program startup, press the RESTORE POS AT N soft
key.
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.
To return to the contour, proceed as described below
in "Returning to the contour. "
