July 2013 8.7 Pallet management 1495
Pallet preset table A preset table for managing pallet datums can be activated in addition to the
preset table for managing workpiece datums. This makes it possible now to
manage the pallet datums independently of the workpiece datums.
Pallet datums are an easy way to compensate mechanical differences
between individual pallets.
To activate the pallet preset table, the token PALLETPRESET = <path/file
name> must be entered in OEM.SYS. Any name can be assigned to the pallet
preset file *.PR, e.g. PALLETPRESET = TNC:\Palletpreset.pr. Only one
workpiece datum and one pallet datum can be active at the same time. Both
datums are effective in sum.
The NC function FN17: SYSWRITE ID540 NR1 is also introduced for activating
a pallet datum. FN 18:SYSREAD ID 540 NR1 is used to read the active line
number. In addition, a pallet datum can be activated by entry of a line number
of the active pallet preset table in the PALPRES column of the pallet table.
The iTNC displays the number of the active pallet preset in the additional
status display.
For determining the pallet datums, there is an additional ENTRY IN PALLET
PRES. TAB soft key in the manual probing functions with which you can also
store the probing results in the pallet preset table.
