LC30P Series AC Servo Driver

Product Overview

The servo system mainly consists of three parts: the controller, the power drive device, the feedback device, and the motor. The controller adjusts the control quantity based on the difference between the given value from the numerical control system and the actual operating value detected by the feedback device; the power drive device acts as the main circuit of the system, on one hand applying electrical energy from the power grid to the motor according to the control quantity to regulate the motor torque, and on the other hand converting the constant voltage and frequency power supply from the grid into the AC or DC power required by the motor; the motor drives the mechanical operation according to the supplied power.

Features

Compatible with 1KW~3.8KW servo motor Support 7 control modes / Frequency division feedback function Support 485 bus, CANopen Support 17bit/23bit servo motor Supports self-learning function, can be adapted to motors of various brands in market
