To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

Encoders are widely used to help control machine position and speed. Typical encoder output, a series of quadrature signals, consists of two full square waves, offset by 90° in phase. The number of ...

Using the LS7366 counter from LSI Computer Systems, designers of feedback systems for encoders, “which typically find use on shafts and machinery,” can offload their system processors, according to ...

Today's consumer devices are defined by portability. However, where these designs incorporate movement, how do product engineers integrate feedback? In portable medical applications, reflective ...

It’s easy to take feedback devices for granted. However, the impact this seemingly minor component can have on a system’s ...

With the introduction of its SES and SEM absolute encoders, SICK has delivered a motor feedback system with the standard HIPERFACE® interface that takes precision and reliability to the next level for ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...

The Zynq all programmable System On a Chip is a recently introduced device from Xilinx which incorporates two ARM A9 CPU cores, I/O peripherals, memory controller, and programmable logic. This paper ...

Encoders are integral parts of motor-control systems that sense mechanical motion, then generate digital signals in response to that motion. The trend today is to create smaller mechanical and ...
