14.5 Workpiece presetting without a touch probe
Saving presets in the preset table
The preset table has the name PRESET.PR and is saved in the directory
TNC:\. PRESET.PR is editable only in the Manual Operation and
Electronic Handwheel modes. In the Programming and Editing mode
you can only read the table, not edit it.
It is permitted to copy the preset table into another directory (for data
backup). Lines that were written by your machine tool builder are also
always write-protected in the copied tables. You therefore cannot edit
them.
Never change the number of lines in the copied tables! That could
cause problems when you want to reactivate the table.
To activate the preset table copied to another directory you have to
copy it back to the directory TNC:\.
There are several methods for saving presets and/or basic rotations in
the preset table:
 Through probing cycles in the Manual or El. Handwheel modes (see
Chapter 14)
 Through probing cycles 400 to 402 and 410 to 419 in Automatic
mode (see the Cycles User's Manual, Chapters 14 and 15)
 Manual entry (see description below)
