Always use the bipolar connection because its physical transmission properties are more
robust. Only if the encoder type employed does not output push-pull signals should you use the
unipolar connection.
6.5.9 Interconnecting optional connections
Depending on the range of options installed, further connections have to be interconnected.
Detailed information about interconnecting these options with the interfaces is provided in the
circuit manual.
6.5.10 Fastening the cable ducts with cable ties
Fasten all cable ducts whose cover faces downward with cable ties. Wind the cable ties around
the entire cable duct. The cable ties must be located at the same positions as in the delivered
state.
