Implementation of SSI Interface

Synchronous Serial Interface (SSI) is a widely used serial interface standard for industrial applications especially, rotary encoders. It is a point-to-point connection from a master (e.g. PLC, microcontroller or other control systems) to a slave (e.g. the rotary encoder).

What is a multiturn rotary encoder?

A multiturn rotary encoder is a sensor that measures the angle of rotation of a shaft, as well as the number of complete revolutions that the shaft has made. This is in contrast to a single-turn encoder, which only measures the angle of rotation, 0 – 360°. Multiturn encoders are used in a variety of applications where it is important to track the position of a moving object, such as in machine tools, robotics, and automation systems.

Accuracy, Resolution and Repeatability

There are several key terms that are critical to specifying the optimal position sensor for a given application. This application note defines these key terms and how they relate to the sensor’s role in the overall system performance. It is important to consider that precision is very much a system issue and can be dominated by mechanical errors such as eccentricity. This paper discusses the most significant mechanical error for rotary applications (eccentricity) and presents eccentricity tolerant position sensor solutions.

Mass Customization: Saving Money in the Long Run

In today’s competitive market, businesses strive to meet the diverse needs and preferences of their customers. One approach gaining traction is mass customization – the ability to tailor products and services to individual customer requirements while maintaining efficiency in production.
