采用高性能单片机和大规模可编程逻辑器件构成硬件系统,并结合绝对光栅编码器研制了用于力机控制的可编程凸轮控制器。替代传统的机械式凸轮控制器,提高了压力机械的控制精度,操作的灵活性。文中介绍了可编程凸轮控制器的系统构成,硬件电路和编程原理。 High-performance single-chip microcomputer and large-scale programmable logic devices constitute a hardware system, combined with the absolute encoder encoder developed for the machine control of the programmable cam controller. Alternative to the traditional mechanical cam controller, improve the control accuracy of pressure machinery, operation flexibility. This paper introduces the programmable cam controller system components, hardware circuits and programming principles.
