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 ...

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 ...

Optical encoders have been used to measure position, speed, acceleration and motion direction for decades, but now they are finding new applications where high performance and miniaturization are ...

The other part of the circuit comprises an independent RC oscillator, which drives an 8-bit counter at a frequency equal to 256 times the PWM frequency. A low output from the 555 timer keeps the ...

The new magnetic encoders from Posital provide absolute position feedback They are available with multi-turn measurement ranges which can be useful when a motor is connected to a screw shaft, cable ...

Every successive generation of a design should be an improvement over the one(s) that preceded it. A new feature, better performance, smaller, lighter, lower power, tastes great, less filling, it’s ...

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 ...
