FAQ: What are servo motor current, velocity and position loops and bandwidths?

June 9, 2016 By Danielle Collins 1 Comment

control loop

Servo motors operate in a closed-loop system, which includes a feedback device, a drive (amplifier), and a controller. The controller uses output from the feedback device to compare the commanded value (position, velocity, or torque) to the achieved value and issues commands to the drive to correct any errors. This process of monitoring feedback and […]
