Signal lines twisted in pairs and shielded.
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!
