基于单片机的新型步进电机运动控制器

Design of a New Motion Controller for Step Motor based on SoC

运动控制器在开放式数控系统中占有很重要的地位。开发了一款基于单片机的新型步进电机运动控制器。硬件部分重点对运动控制器的脉冲分频电路、RS-232通信接口电路、D/A转换电路、V/I转换电路、开关信号输入电路、系统抗干扰电路等进行了设计和分析;软件方面提出了系统的总体架构。

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.
