The Servo Motor Control System Which is Based on S7-200 Design
ABSTRACT
In this paper, first of all, from the entry point for the development of PLC, PLC, introduced in today’s automation and control of the tremendous role. In the PLC control system PLC fieldbus technology equipment and on-site, client, server, real-time communication between to decentralized optimization control is a hot field of industrial control problem. Integrated quality control system designed to directly affect the economics of industrial production. Depth study of the application of PLC and fieldbus control technology for our country in the field of industrial automation to make a useful contribution to further development。
With flexible manufacturing technology, computer integrated manufacturing technology and information technology, the manufacturing sector in today's world is about to enter an era of full automation, the implementation of automated manufacturing systems of human production has entered a new era of modern civilization. AC servo system in response to fast speed and high precision, wide speed range, good speed performance characteristics of control in the manufacturing sector has been widely used, has gradually become the field of industrial automation control of the mainstream movement。
In this paper, the analysis of the PLC and servo control in the automatic control of the effective integration of automation and control would bring enormous benefits, this article from the analysis of the technical aspect PROFIBUS fieldbus, PROFIBUS-DP protocol research and message structure, the SIMATIC S7-200 series PLC in the bus PROFIBUS applications. Production lines in the original electrical wiring schematic diagram based on the use of PLC control system to replace the relay to complete the selection of hardware, block definition and simulation ladder program editing and debugging, downloading, to achieve the wire production line PLC control; At the same time, the use of Siemens WinCC software implementation of the host computer and the PLC communications, the completion of the wire production line monitoring and control system design。
The purpose of this study is to examine the S7-200 based on the servo motor system design, system design, including PLC, servo amplifier and servo motor, relay and motor control system design。
