A new software product promises to boost the bandwidth of a servo drive’s current control loop, opening up new possibilities in industrial motion control applications. Fast Current Loop software is ...

Motion-control architecture appears to be compact and simple. But in reality, the individual servo loops-current, velocity and position-have been traditionally shared between a drive and a separate ...

Step motor control offers a powerful alternative in the right applications. Step motors are popular first and foremost because they are easy to use. They do not require an encoder to maintain their ...

Aerotech’s XL4s linear amplifier for closed-loop servo control of voice coil and single-phase motors eliminates the nonlinearities common with PWM amplifiers. The unit provides deterministic behavior, ...

Combining a high-torque step motor with an on-board drive, encoder, controller and closed-loop servo software into a single package, the integrated motors save on space, wiring, and cost over ...

Sponsored by Texas Instruments: Single-chip microcontrollers geared to servo and other industrial/EV control applications help engineers cost-effectively design multiple-axis systems. As manufacturing ...

Just over a decade ago, an article titled, "Advanced Control Strategies Move into the Field" (Control, October 2008), highlighted three evolving trends in the process control world that would "make ...
