Absolute encoders produce a digital word value indicating true position within a full 360⁰ rotation. The maximum practical resolution is approximately 16 bits (1 part in 65,536). Absolute encoders have a more complex installation and for high resolutions, the data is often sent serially with SSI being a common format. Absolutes are very good at position control, especially if power outages or long periods of inactivity are expected. |
