Traversing Reference Points - HEIDENHAIN TNC 620 User Manual

Traversing reference points

If the control performs the self-test successfully, it then displays the
Traverse reference points dialog.
Refer to your machine manual.
Switching on the machine and traversing the reference
points can vary depending on the machine tool.
If your machine is equipped with absolute encoders, you
can leave out crossing the reference points.
If you intend only to edit or graphically simulate
NC programs, you can select the Programming or Test
Run operating mode immediately after switching on the
control voltage, without needing to home the axes.
You can neither set a preset nor modify a preset via the
preset table without having homed the axes. The control
issues the Traverse reference points message.
You can traverse the reference points later. For this
purpose, press the PASS OVER REFERENCE soft key in
Manual operation mode.
Traverse the reference points manually in the displayed sequence:
For each axis press the NC START button
The control is now ready for operation in the
Manual operation mode.
As an alternative you can cross the reference points in any
sequence:
Press and hold the axis direction button for each
axis until the reference point has been traversed
The control is now ready for operation in the
Manual operation mode.
