在工业自动化控制系统中,最为常见的是PLC和变频器、伺服驱动器的组合应用,并且产生了多种多样的PLC控制变频器、伺服驱动器的方法。其中,采用Profibus DP总线通信方式实施控制的方案,是西门子广大用户所熟悉和普遍使用的传统控制方案。选择S7—300T—CPU和变频器、伺服驱动器的组合应用,采用成熟的PROFIDRIVE通信协议实施控制,是传统的PLC控制变频器、伺服驱动器方案的升级。用户只需要通过STEP7软件,在硬件组态中将所有的驱动器(变频器、伺服驱动器)连
In the industrial automation and control system, the most common is the combination of PLC and frequency converter, servo driver, and produces a variety of PLC control inverter, servo drive method. Among them, the use of Profibus DP bus communication implementation of the program control, Siemens majority of users are familiar with and commonly used traditional control programs. Select S7-300T-CPU and drive, servo drive combination of applications, the use of mature PROFIDRIVE communication protocol implementation control, is the traditional PLC control inverter, servo drive program upgrade. Users only need STEP7 software in the hardware configuration of all the drives (drive, servo drive) with
