12.2 Connecting an incremental encoder

12.2 Connecting an incremental encoder
Note
Because the physical transmission media is 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.
Note
The technical data of the incremental encoder inputs (X177.41 to 48) and further information
on how to connect an incremental encoder are given in Chapter 6.
HTL encoder, bipolar, with zero signal
Improved protection against induced interference is achieved by twisting the signal lines in pairs.
