The Analog to SSI Interpolator - SC2SSi provides (SSi) conversion of the na ve analogsignals to full rota on absolute posi on and Synchronous Serial interface.

The SC2SSi provides:

Real me servo feedback

Setup and Con gura on via (RS-422 & NCP)

Online monitoring

BIT (build in tests)

SC2SSi - analog to digital SSi interpolatorfor absolute position Electric Encoders

The SSi transmits the absolute posi on data from theElectric Encoder in response to the controller clockpulses. The Electric Encoder and controller are linkedby clock and data di ff eren al signal lines.

The nal performance in terms of accuracy andresolu on are according to the original characteris csof the Electric Encoder and the interpolator setup.

The digital SC2SSi interpolator provides advancedcalibra on and monitoring op ons using the NCP(Netzer Communica on Protocol) and factory suppliedso ware tools as the SSi explorer.
