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 ...

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 ...

Noise on a signal creates a triggering challenge for test equipment, especially oscilloscopes. Becuase the instrument itself also contributes noise, small signals in the millivolt range need proper ...

The RS-485 standard defines a popular and widely used serial data interface and network that’s been in use for over 30 years. It’s found in factories, process control plants, building automation, and ...

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 ...

1. This optimised analogue-conditioning circuit can avoid signal distortion caused by nonlinearities, and guarantee an optimum interface between the encoder and ADC. 2. shown is a normalised RC filter ...

Alignment of optical encoder commutation signals to a Brushless DC (BLDC) motor could be thought of as being comparable to timing the distributor on a car engine. The distributor tells the spark plugs ...
