Information concerning the setting of the reference point
Move the spindle exactly to the position which corresponds to the reference value programmed
before accord. to chapter
6 . The mechanically mounted reference point transmitter must now be
definitely active (see Fig. 3 ).
The encoder can be turned without causing any movement of the driving spindle, if you
untighten the clamping ring or coupling. You can now search the index signal of the encoder
(voltage change) by using for example a voltmeter and carry out the adjustment of the reference
point. When the index and reference point transmitter signals are positioned as described in
Fig.
4 , the clamping ring and the coupling of the incremental encoder are retightened.
