Research on Multi-Speed Control of Variable-Frequency Drive

Abstract:

This paper introduces a noval experimental teaching project. Different from previous experiment, in this project, three-phase motor can operate at multi-speed mode or continuously variable speed mode controlled by PLC and VFD. The obvious characteristic of the experiment is that the VFD is controlled by PLC automatically. The configuration of the experiment including hardware and software is introduced in detail. The results of the execuation of the PLC program reveals that three-phase motor can operate in two modes according to the instructions from PLC. In addition, the speed can be changed with the corresponding parameters seting. Therefore, the knowledge of PLC and VFD are combined in one teaching project, through which student can master more practical technique. The work of this paper is significant for improving the students’ comprehensive capability.
