Frequency Control of Motor Speed Control System Based on PLC and HMI

In order to improve the degree of comprehensive application and energy saving effects of variable frequency speed regulation system,solve the frequency converter running status real-time monitoring in engineering application,realize the intelligent control and high efficiency and energy saving of speed control system,this paper put forward the frequency control of motor speed control scheme based on PLC and touch screen,in order to realize the control of frequency converter speed control system and monitoring. The practical application shows that the system can adapt to a variety of industrial control environment,have friendly man-machine interface,the energy conservation effect is obvious,achieved the desired effect.
