Definition of key parameters of servo drives

Leave a Comment / Uncategorized / By

Servo drives, also called “servo controllers” or “servo amplifiers”, are control devices used to control servo motors. They work similarly to frequency converters acting on ordinary AC motors and are an important part of servo systems, mainly used in high-precision positioning systems. Usually, servo motors are controlled in three ways: position, speed, and torque, to
