3.2 Program Run
Mid-program startup
The RESTORE POS AT N feature must be enabled and adapted by the machine tool builder. Refer to the operating
manual of your machine tool for further information.
With the RESTORE POS AT N feature (block scan) you can start a part
program at any block you desire. The TNC scans the program blocks up to
that point. Machining can be graphically simulated.
If a part program has been interrupted with an INTERNAL STOP, the TNC
automatically offers the interrupted block N for mid-program startup.
• 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.
• If the part 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 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 3D ON/OFF soft key to define whether the TNC is to return to the
contour in a tilted or in an untilted coordinate system.
Go to the first block of the current program to start a block scan.
Select mid-program startup.

Enter the block number N at which the block scan should end.
Enter the name of the program containing the block N.
If block N is located in a program section repetition, enter the number
of repetitions to be calculated in the block scan.
Start the block scan.
Return to the contour (see next page).
