There are several methods for saving datums and/or basic rotations in
the preset table:

„

Through probing cycles in the Manual Operation or Electronic
Handwheel

modes (see User’s Manual, Touch Probe Cycles,

Chapter 2)

„

Through the Probing Cycles 400 to 419 (see User’s Manual, Touch
Probe Cycles, Chapter 3)

„

Manual entry (see description below)

Basic rotations from the preset table rotate the coordinate
system about the preset, which is shown in the same line
as the basic rotation.

When setting a preset, take care that the position of the
tilting axes matches the corresponding values of the 3-D
ROT menu. Therefore:

„

If the “Tilt working plane” function is not active, the
position displays for the rotary axes must = 0° (zero the
rotary axes if necessary).

„

If the “Tilt working plane” function is active, the position
displays for the rotary axes must match the angles
entered in the 3-D ROT menu.

Line 0 in the preset table is write protected. In line 0, the
TNC always saves the datum that you most recently set
manually via the axis keys or via soft key.
