The TNC is now ready for operation in the Manual Operation mode.
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 
“Activating manual tilting,” page 62. The TNC then interpolates the 
corresponding axes. 
The NC START button has no function. Pressing this button may result 
in an error message.

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 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.
