Note
Operation of unipolar HTL encoders
When unipolar HTL encoders are used, terminal block A*, B*, and R* must be jumpered with
M encoder (
-X531).

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.
