摘  要： CAN总线（Controller Area Network）是广泛应用在离散控制领域的串行总线。由于CAN总线数据通信具有突出的可靠性、实时性和灵活性，所以在由伺服系统作为执行机构的分布式控制现场中，得到很广泛的应用。通过CAN伺服系统可以独立地完成各种运动控制。通过CAN总线，主控机，DSP和SN65HVD230之间的数据传输与控制，使得伺服的使用更加灵活和方便，能更好的应用在各种分布式的控制系统中。

Abstract: The controller area network is a serial bus communications, and it is widely used in the discrete control system.Communication system based on CAN bus is more reliable,better real time ability and flexibility,so the CAN has been widely used in distributed control field performed by AC servo drive system.Controlled through CAN,AC servo system can finish any kinds of movement.The data are exchanged among computer,digital signal process and SN65HVD230 by CAN,which makes the AC servo drive system more reliable,safe and efficient.Distributed control system are also starting to utilize the benefits of AC servo drive system with CAN.
