Absolute encoder accuracy
1st Quarter 2018
Other technologies
Absolute encoders are ideal for applications where a power outage requires machinery to reorient without having to reconfigure any of its settings. This is because they are suited to applications where positional information is required periodically and not continuously. When power is restored, the system master or controller identifies the position as soon as the encoder starts relaying information again.
Generally, absolute rotary encoders are used as these offer absolute accuracy in determining the position of an object. However, the encoder cannot simply collect feedback data. It needs to be sent somewhere in a language that can be interpreted by the system. Bryant explains that absolute encoders use binary coding which can be translated into many different protocols.
The Hengstler Acuro range of absolute encoders finds application where both speed and position are required, and where there is no room for error. Using a static reference point, the encoder will determine the speed or position of an object and can be configured to measure, monitor and control the linear movement and acceleration.
Innovative engineering has resulted in optimised functionality and ease of operation. Designed as a modular system, it can be configured to allow the correct variant for an application taking factors such as motor feedback and automation into account. The Hengstler Acuro is equipped with an open BiSS sensor interface allowing for optimal integration into any system.
