KJD series Ac servo driver

KJD series Ac servo driver

KJD series is a high-performance, cost-effective all-digital AC servo driver launched by our company.

Features: High-performance ARM processor + FPGA framework is used for high-speed signal acquisition and data processing, and the use of intelligent power module (IPM), compared with the using of low-cost FET single-tube assembly solution, can accurately control motor current. With the advanced and optimized control algorithm, it can accurately control the torque, speed and position of the motor. It ensures the smooth operation of the motor and quick setting.
