摘要
介绍以FX2N-80MRPLC为主控制器,结合N2-420变频器,采用集选控制的方式开发的一套交流变频调速的多层电梯控制系统。通过程序的设计与调试解决了以下问题:运行速度控制;定向和平层控制;门控制;内指令和外召唤信号的数字控制。
This paper introduced a frequency conversion adjusting speed multilayer elevator control system , that adopted collective selective control method based on FX2N-80MK PLC host controller and N2-420 transducer. The program of the system resolved running speed control, directional and leveling control, door control and digital control of car call and hall call.
