Abstract: This article mainly explains the application theory of Delta’s inverter、PLC、HMI products in Multi-function Spinning Machine. In this system, the inverter is used for realizing the actions of revolution, and the PLC modules adjust the rotate speed by the way of RS-485 communication protocol; The Analog Expansion Modules of PLC control the pressure and flow rate of the fluid cylinder; The current position signals of both sides of fluid cylinder are obtained by the encoder; The HMI can monitor the operation state and the alarm message. Thus, the whole network displays the system integration advantages of Delta’s industrial automation products.
