 PALPRESET (entry optional):
Preset number from the pallet preset table. The TNC interprets the
preset number defined here as pallet datum (PAL entry in PAL/PGM
column). You can use the pallet preset to compensate mechanical
differences between the pallets. A pallet preset can also be
activated automatically when a pallet is added
 PRESET (entry optional):
Preset number from the preset table. The preset number defined
here is interpreted by the TNC either as a pallet datum (PAL entry in
the PAL/PGM column) or as a workpiece datum (PGM entry in the
PAL/PGM
line). If there is a pallet preset table active on your machine,
then use the PRESET column only for workpiece datums
 DATUM
(entry optional):
Name of the datum table. The datum table must be stored in the
same directory as the pallet table. Otherwise you must enter the full
path name for the datum table. Datums from the datum table can be
activated in the NC program with Cycle 7 DATUM SHIFT
 X, Y, Z (entry optional, other axes also possible):
For pallets and fixtures, the programmed coordinates are referenced
to the machine datum. For NC programs, the programmed
coordinates are referenced to the pallet or fixture datum. These
entries overwrite the datum that you last set in the Manual mode of
operation. With the miscellaneous function M104 you can reactivate
the datum that was last set. With the actual-position-capture key,
the TNC opens a window that enables you to have the TNC enter
various points as datums (see table below):
Position Meaning
Actual values Enter the coordinates of the current tool position
referenced to the active coordinate system.
Reference
values
Enter the coordinates of the current tool position
referenced to the machine datum.
ACTL measured
values
Enter the coordinates referenced to the active
coordinate system of the datum last probed in
the Manual operating mode.
REF
measured
values
Enter the coordinates referenced to the machine
datum of the datum last probed in the Manual
operating mode.
