摘要
通过分析变频调速技术在通用桥式起重机中的应用,根据其原有的控制结构,综合组态软件和PLC、变频器技术,提出了一个基于PLC控制变频器技术的系统控制结构,并且采用此体系结构进行了对桥式起重机变频调速控制的研究。
This paper discusses the applications of the frequency control technology in general bridge crane. Based on the original control structure of general bridge crane, an improved system control structure has been put forward with the combination of configuration software, PLC and inverter technology. This system control structure can achieve the frequency control of the bridge crane.
