Note
We recommend that bipolar encoders are used.
When using unipolar encoders the unused negative track signals can either be left
unconnected or connected to ground. This results in two different operating points.

2) The absolute level of the individual signals varies between 0 V and VCC of the measuring system.
NOTICE
Prefabricated cable for 5 V - TTL encoder
If a 5 V - TTL encoder (6FX encoder) is used, the connecting cable 6FX8002-2CR00-....
has to be used.

2) Because the physical transmission properties are more robust, the bipolar connection should
always be used. The unipolar connection should only be used if the encoder type does not output
push-pull signals.
