Quadrature encoders have many uses in position-sensing applications. This implementation uses a Xilinx complex programmable logic device (CPLD) to count the pulses from the encoder and determine the ...

Special hardware can overcome software latency that may otherwise negate precise motion control. Precision motion control is virtually never an end in itself. Rather, it ties position to other events ...

That level of resolution is ideal for commutation, high-speed motor control, position/velocity control, and replacement of potentiometers and optical encoders. It’s a low-power 3.3-V (or 5-V) device, ...

Direct drives place rigorous demands on position-signal quality. Optimum measuring signals increase the quality of the machined workpiece surface, reduce vibration in the machine frame, stop excessive ...

Rotary encoders sense changes in the position of a rotating shaft, then generate signals that send speed, direction, and position information to a receiving device such as a counter, drive, or ...

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 ...
