14.2 Pallet preset management
Fundamentals
Refer to your machine manual.
This feature must be enabled and adapted by the
machine tool builder.
Changes to the pallet preset table must always be made
in agreement with your machine tool builder!
The pallet preset table is available to you in addition to the
workpiece preset table (
preset.pr
). The workpiece presets refer to
an activated pallet preset.
The control shows the active pallet preset in the status display on
the PAL tab.
Application
Pallet presets are an easy way to compensate e.g. mechanical
differences between individual pallets.
You can also completely align the coordinate system to the pallet
by e.g. positioning the pallet preset in the center of a clamping
tower.
Using pallet presets
If you want to use pallet presets, insert the
PALPRES
column in the
pallet table.
Enter the preset number from the pallet preset table into this
column. Usually, you always want to change the pallet preset when
you insert a new pallet, i.e. in the PAL type lines of the pallet table.
NOTICE
Danger of collision!
Despite a basic rotation due to the active pallet preset, the
control does not show a symbol in the status display. There is a
danger of collision during all subsequent axis movements!
If necessary, check the active pallet preset in the
PAL
tab
Check the traverse movements of the machine
Use pallet presets only in conjunction with pallets
