TO TURN POWER OFF
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 traverse the reference points later by pressing
the PASS OVER REFERENCE soft key in the Manual
Operation mode.
Inappropriate switch-off of the TNC can lead to data loss.
