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 ...

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 ...

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 ...

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, ...

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 ...

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 ...

POSITAL’s measuring wheel accessories for its IXARC family of rotary encoders enables these devices to make accurate linear motions and position measurements. “Encoders are great for measuring ...
