Design of a New Motion Controller for Step Motor based on SoC KUANG Yin1,2 ,TANG Nian-qing1,2,WEI Yu-hua3 （1.Department of Computer and Information Science, Neijiang Teachers College, Neijiang, Sichuan 641112,China; 2. Key Laboratory of Network Application Engineering, Neijiang Teachers College, Neijiang, Sichuan 641112,China 3.HongYuan Group of Sichuan,641000, Sichuan ,China） Abstract: The motion controller plays a significant role in the open-architecture NC system. A new motor controller for step motor based on SoC is developed in this article. It designs the hardware system of motion controller, lays stress on analyzing the pulse output circuit, serial communication interface circuit, D/A conversion circuit, V/I conversion circuit, switch input circuit and the anti-interference circuit. At last, it confirms the general architecture of software.
