LC10D Series AC Servo Drives

Product Overview

A servo system primarily consists of three main components: the controller, the power drive unit, and the feedback device together with the motor. The controller adjusts the control signal based on the difference between the setpoint specified by the CNC system and the actual operating value detected by the feedback device. The power drive unit serves as the system’s main power loop: on one hand, it converts electrical energy from the power grid into appropriate power for the motor according to the magnitude of the control signal, thereby regulating the motor torque; on the other hand, it converts the constant-voltage, constant-frequency grid supply into the AC or DC power required by the motor. The motor, in turn, drives the mechanical load in accordance with the supplied power.
