Because the transmission technology 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.
As of a cable length of 200 m, use a power supply cable with a cable cross-section ≥ 0.75 mm²!

Note
The CUA32 control unit adapter also provides an encoder interface for an HTL, TTL or SSI encoder.
The technical data of the CUA32 adapter module can be found in the SINAMICS S120 AC Drive
