The hydraulic pump is one of the core part of the system , which has a high request for speed precision control .The system achieves the main functions such as strict run logic between the main motor and the other sets of auxiliary motors, remote and local operation, good human-computer interaction, and other functions. The paper has detail introduction to the design process, and the main content is as follows: This paper introduces the basic principle of frequency control of motor speed, and the use of the ABB ASC800 converter. With PLC system and the function of each composition module are introduced, the paper also discusses the various functions and its programming. The paper puts forward the control scheme according to the design requirements and expounds the control circuit design in detail. The paper introduces the schneider vigeo citect configuration software and its composition and functions, as well as the PC control interface design completed with the software. The paper discusses the communication scheme and the specific configuration of the control system .
