SERCOS 기반의 고속 고강성 이송시스템 드라이버 개발

Development of the linear motor driver with high speed and stiffness based on SERCOS

In this paper, a controller for the linear motor with high speed and stiffness is implemented using SERCOS interface which is a real time communication protocol between the numerical controller(NC) and the motor driver. The proposed controller is mainly composed of current, speed, and position controller, which are designed using the 32-bit DSP(TMS320C31), a high-integrated logic device (EPM7128), and Intelligent Power Module(IPM) to enhance reliability and compactness of the system. The experimental results show the effective performance of the proposed controller for he linear motor with high speed and stiffness.
