The single-cable technology used involves the transmission of power and encoder signal in a single cable. This reduced cabling minimizes costs, while the fewer number of connectors reduces susceptibility to connector failures. A special feature of the BiSS Line interface is the implementation of the Forward Error Correction function, which is said to improve availability of data communications, even with faulty cables and plug connections. A four-wire system (with separate conductors for communication and power supply) or a two-wire variant (with combined communication and instrument power supply on a wire pair), are also available, based on the same communications protocols. The easy-to-install motor feedback kits, which feature 17-bit electronic resolution, bridge the gap between simple resolvers and more complex and expensive optical encoders for servomotors, robot joints and other applications where absolute rotary position feedback is required.
