The Design of Stepper Motor Control System Based on PLC
Abstract: According to the traditional single-chip stepper motor control needs not only the device structure is tedious and prone to errors by using the PLC system is designed to control the stepper motor. The characteristic of PLC stepper motor control can the hardware circuit and software control combine to form a modular control system, simple structure, easy to maintain and update, if the device is moving distance and speed in the process of operation are determined, through a dedicated driver to control the stepping motor using PLC movement is a kind of ideal control mode. This paper is introduced the Siemens S7-200 PLC method to control four stepper motor, constitute the system components and connections, stepper motor reversible and successful operation of deceleration shows feasibility of the design is reasonable.
