There are several methods for saving datums and/or basic rotations in
the preset table:
„ Through probing cycles in the Manual Operation or El. Handwheel
modes (see Chapter 14)
„ Through the probing cycles 400 to 402 and 410 to 419 in automatic
mode (see User’s Manual, Cycles, Chapters 14 and 15)
„ 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.
Remember to ensure that the position of the tilting axes
matches the corresponding values of the 3-D ROT menu
when setting the datum. Therefore:
„ If the "Tilt working plane" function is not active, the
position display for the rotary axes must be = 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.
The 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. If the datum
set manually is active, the TNC displays the text PR MAN(0)
in the status display.
