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, ...

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 ...

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 ...

It’s easy to treat optical encoders as “black boxes” that need minimal consideration before they are installed to translate rotary motion into position or velocity feedback signals for a motion ...
