步进电机细分驱动技术的软件实施

步进电机是采用脉冲信号作为驱动信号源的电动机,在微量进给及准确定位等数控领域有着广泛的应用。为使步进电机能更好地满足控制要求,需要采用细分驱动技术。本文论述的是利用软件编程、通过设定循环控制字来分配驱动脉冲信号源,并利用升／降速技术来提高步进电机的控制精度。

Driving technology of subdivided procedure is adopted on Step electric motor throng programming

Step electric motor is a kind of implement whose driving source is the pulse single, and it is applied more extensively in the domain of digital controller that needs tiny procession and accurate locating. For purpose of making the motor satisfy control request, driving technology of subdivided procedure is adopted. In this paper we will discuss how to make use of software monitor and set up circulate control word to distribute the source of driving single and how to crease the accuracy of step electric motor by technology on rising and declining speed.
