654 Test Run and Program Run
16.4 Program Run
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 (M00 or STOP), the block scan is
interrupted there. Press the machine START button to
continue the block scan.
Please note that mid-program startup in a radius-
compensated contour, directly after a programmed
interruption (M00 or STOP), can lead to contour damage. The
TNC cannot establish a connection between the contour
programmed after the STOP block with the the contour
programmed before the STOP block.
After a block scan, return the tool to the calculated position
with RESTORE POSITION.
Tool length compensation does not take effect until after
the tool call and a following positioning block. This also
applies if you have only changed the tool length.
The miscellaneous functions M142 (delete modal program
information) and M143 (delete basic rotation) are not
permitted during a mid-program startup.
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).
