数控系统中基于CPLD的步进电机驱动模块的设计

摘要

介绍一种采用大规模可编程逻辑器件CPLD来控制步进电机的方法,对电机的控制方式为四相八拍。通过对CPLD进行编程,从而对电机达到启动,停止,正转,反转的控制。采用的编程语言为VHDL语言,使用的编程环境为MAX＋PLUS II。最后通过软件仿真达到精确的仿真结果。%In CNC system,the step-motor is controlled by single chip,now another method is introduced in the article that the step-motor is controlled by CPLD.This method of motor control is 4 phase and eight time.Through the program of CPLD,the motor can be controlled to start,stop,rotate and reverse.The program language is VHDL and the Program environment is MAX＋PLUS II.At last the emulation result is realized exactly.
