Design of Honey Separation Machine Control System Based on PLC and Frequency Converter

This article describes that according to sugar honey process requirements,combines with the Siemens PLC-200 and frequency converter to control sugar centrifugal system automatically.It replaces the last multiple AC motor control,and realizes the multistage speed control.It uses Siemens touch screen MP277 as man-machine exchange interface,real-time displays the centrifuges running and controls parameter settings.The honey machine control system with good speed performance,energy-saving effect and other features.It improves the quality of white sugar and plays an important role of it.
