Abstract: Positioning systems in processing machines, precision measuring instruments, and handling robots require fast logging of position data and also quick recognition of any changes. High resolution encoders and linear scales feed position data to the central control through an encoder interface. This interface must be selected so that it satisfies the timing requirements of the control unit. The vast number of available interfaces can also complicate the selection task as well as the implementation task for the designer. Beside the great range of proprietary digital interfaces there are also open-source standards available, such as the SSI/BiSS interface for absolute position reading. However, if a fast capture of changes in direction and/or of a very high position resolution is required, serial digital interfaces are limited in capacity.

 

As an alternative, there are of course the classic open-source encoder interfaces that transmit position as analog sine/cosine signals or position changes using incremental A/B signals as well. This article describes the requirements, alternatives, and possible solutions to this problem.

 

Keywords: measurement of position; encoder interface, SPI/BiSS interface, iC-MD
