| Abstract: | This paper using PLC, inverter, asynchronous motor and rotary encoder to structure a closed loop system of AC variable frequency drive. The thesis described the constitution and working prin-ciple of the variable-frequency drive,give a control method of system and design the ladder diagram pro-gram, using MCGS configuration software to design the monitoring interface of system. The trial operation results show that the system has high reliability,good scalability and fast dynamic response. |
