Abstract: In order to solve the disadvantage of the complexity on the conventional twister,put forward a controlling system in twister based on PLC which was droved by two asynchronous motors and two servo motors.The moving of twisting and winding had been realized through adopting RS-485 frequency communication technology and servo motors had droved to-and-froguiding-yarn moving.The hardware and software were realized.The result showed that this controlling was dependable and the driving was accurate.
