Motor runaway conditions not only increase expenses, but can also create dangerous situations. The incorporation of a Velocity Limited Torque Mode function on a servo system can mitigate runaway motor ...

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.

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 ...

1. Don't fear servos. There are many different levels of positioning and motor controls now. Some basic variable frequency drives can even be used to do what could have been done only with coordinated ...
