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 ...

Disturbance rejection, like command tracking, is usually expressed graphically. The graphs, called disturbance rejection plots, show the effect of PIV gains on disturbance torque applied to the shaft ...

This article originally appeared on Heidenhain.us and has been published here with permission. Servo motors are electric motors that let engineers and designers precisely control position, velocity ...

A new all-in-one brushless servo platform brings EtherNet/IP networking, high power density, and washdown-ready design into a ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

Perhaps the most difficult control problem for a drive servo is that of going down a ramp. Any back drivable drive servo will exhibit a freewheeling velocity on a given ramp. This is the speed at ...
