4.12 Managing Pallet Tables

Pallet table management is a machine-dependent
function. The standard functional range will be described
in the following. Refer to your machine manual for more
information.
Pallet tables are used for machining centers with pallet changer:
The pallet table calls the part programs that are required for the
different pallets, and activates datum shifts or datum tables.
You can also use pallet tables to run in succession several programs
that have different datums.
Pallet tables contain the following information:
PAL/PGM (entry obligatory): Identification for pallet or NC program
(select with ENT or NO ENT)
NAME (entry obligatory): Pallet or program name. The machine
tool builder determines the pallet name (see Machine Manual).
The program name must be stored in the same directory as the
pallet table. Otherwise you must enter the full path name for the
program.
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 pallet names,
the programmed coordinates are referenced to the machine
datum. For NC programs, the programmed coordinates are
referenced to the pallet datum.
If you have not defined a pallet before an NC program,
the programmed coordinates are then referenced to the
machine datum. If you do not define an entry, the datum
that was set manually remains active.
To select a pallet table:
Call the file manager in the Programming and Editing or Program
Run mode: Press the PGM MGT key.
Display all .P files: Press the soft keys SELECT TYPE and
SHOW .P .
Select a pallet table with the arrow keys, or enter a new file name
to create a new table.
Confirm your entry with the ENT key.
