Executing a pallet
table

Meaning
Optional field:
Name of the datum table
Datum tables without paths are searched for in the directory
with the pallet tables.
Optional fields:
Definition of the datum.
For pallet entries, the values are referenced to the machine
datum (MP960.x).
For NC programs the values are referenced to the pallet
datum. Only the fields X, Y and Z are used in the standard
format.
Optional fields:
Safe positions; with FN18: SYSREAD, these positions can be
read in NC macros.
If — due to a tool change — an NC program must be stopped
during tool-oriented machining, the TNC enters a code. This
code enables the TNC to resume the machining process at the
position where it has been stopped.
Optional field (not used in standard format):
Location of pallet.
If the LOCATION field is used, an NC program can be run only
if this field contains the entry MA (= pallet for the machine).
Optional field:
If an entry is made in this column, the line of the entry will not
be run.
If more than one program or pallet is to be run, the next
permitted line is used. Unlocked lines in a locked pallet are also
skipped.
Freely definable
The pallet table is selected and started with PGM MGT like a normal part
program in the PROGRAM RUN, SINGLE BLOCK and PROGRAM RUN, FULL
SEQUENCE operating modes.
Pallet entries (PAL) and fixture entries (FIX) result in a call for an NC macro.
Program entries (PGM) are run like a PGM CALL.
7 7 7 7
With MP7683 bit 6, specify if the NC program and the pallet table should
appear simultaneously in the split screen, or if the active NC program or
active pallet table should be shown individually.
7 7 7 7
With MP7683 bits 0 to 2, specify the operating sequence following an NC
start.
7 7 7 7
With MP7683 bit 3, specify the operating sequence upon reaching the end
of the pallet table.
