3. Select the axis to be traversed.

The selected axis moves to the reference point.
If you have pressed the wrong direction key, the action is not
accepted and the axes do not move.
A symbol is shown next to the axis if it has been referenced.
The axis is referenced as soon as the reference point is reached. The actual value display is
set to the reference point value.
From now on, path limits, such as software limit switches, are active.
End the function via the machine control panel by selecting operating mode "AUTO" or
"JOG".
2.2.2 User agreement
If you are using Safety Integrated (SI) on your machine, you will need to confirm that the
current displayed position of an axis corresponds to its actual position on the machine when
you reference an axis. Your confirmation is the precondition for the availability of other
Safety Integrated functions.
You can only give your user acknowledgement for an axis after it has approached the
reference point.
The displayed axis position always refers to the machine coordinate system (Machine).
Option
User acknowledgement with Safety Integrated is only possible with a software option.
Procedure
1. Select the "Machine" operating area.
2. Press the <REF POINT> key.
