TECHNICAL DATASHEET Absolute Encoder AC 58 - BiSS / SSI DATA FORMAT SSI Multiturn SYNCHRONOUS-SERAL TRANSFER (SSI) Synchronous readout of the encoder data is according to the clock rate given by the SSI-counterpart. The number of clock rates is determined by the type of encoder (singleturn resp. mul- titurn) and the configuration of the special Bits as defined. For multiple transactions (the stored va- lue is readout several times successively) a fixed clock rate per transaction must be kept (for singleturn 13 resp. 14 clocks, for multiturn 25 resp. 26 clocks). In the rest position, when the last clock brush has passed by more than 30µs, the data output is logically at "1".

With the first descending clock edge the encoder data and the special bits are loaded in the shift register of the encoder interface. With each ascending clock edge the data bits are serially readout, beginning with the MSB. At the end of the data transfer the data output is set to logically "0" for approx. 20µs. If within these 20µs a further clock brush reaches the encoder interface, the already transferred data is readout once again. This multiple transfer of the same data makes it possible to recogni- ze transfer errors. After the 20µs the data output goes to its rest position, logically "1". Subse- quently new encoder data can be readout.
