The combination of the latest Servo Motor designs, extremely flexible robots and an eclectic mix of other advanced technologies are the key factors driving the rapid growth of new fabrication ...

Faster, smaller, and smarter is the mantra of today's servo-controlled machines. As a result, end users have come to expect more and better performance, forcing designers to continuously improve ...

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

Authored by: George Ellis, Chief Engineer, Servo Systems, Kollmorgen, Radford, Va. Key points: Three key measures — accuracy, response, and robust stability — characterize how servosystems perform.

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...
