Additional functions for the TNC 426, TNC 430
Traversing the reference point in a tilted working plane
The reference point of a tilted coordinate system can be traversed by
pressing the machine axis direction buttons. The “tilting the working
plane” function must be active in the Manual Operation mode, see
“To activate manual tilting:,” page 29. The TNC then interpolates the
corresponding axes.
The NC START button is not effective. Pressing this button may result
in an error message.
Switch-off
To prevent data being lost at switch-off, you need to run down the
operating system as follows:
U U U U Select the Manual mode.
U U U U Select the function for shutting down, confirm again
with the YES soft key.
U U U U When the TNC displays the message Now you can
switch off the TNC in a superimposed window, you
may cut off the power supply to the TNC.
The reference points need only be traversed if the
machine axes are to be moved. If you intend only to write,
edit or test programs, you can select the Programming
and Editing or Test Run modes of operation immediately
after switching on the control voltage.
You can then traverse the reference points later by
pressing the PASS OVER REFERENCE soft key in the
Manual Operation mode.
Make sure that the angle values entered in the menu for
tilting the working plane match the actual angles of the
tilted axis.
Inappropriate switch-off of the TNC can lead to data loss.
