ABB 086407-502 servo drives (servo drives), also known as “servo controller”, “servo amplifier”, is used to control a servo motor controller, its role is similar to the inverter acting on the ordinary AC motor, is a part of the servo system, mainly used in high-precision positioning system. Generally, the servo motor is controlled through three ways of position, speed and torque to achieve high-precision transmission system positioning, and it is currently a high-end product of transmission technology.
In the servo drive speed closed loop, the real-time speed measurement accuracy of the motor rotor is used to improve the speed loop speed controller
