摘要
为保证门座起重机运行的高效性和可靠性,在门座起重机的控制系统应用变频调速技术是一种有效的解决方法。在分析门座起重机起升机构的电气控制系统性能要求的基础上,本文提出一种由可编程序控制器实现的变频调速方案,且详细给出了变频器的选型以及参数设定与调整,门座起重机在实际工程的良好运行证实了该方案是有效的。
In order to ensure the reliability and high effectiveness of portal crane operation,the inverter used in the control system of portal crane is an effective solution.In the analysis of performance requirements for portal crane hoisting mechanism,a frequency control method by programmable logic controller（PLC） implementation is proposed in this paper.And the type selection,parameter setting and adjustment of inverter are presented in detail.Portal Crane working well in practice proves that the new method is effective.
