摘要
设计一种由西门子6RA70系列直流调速器和PLC等构成的矫直机电气控制系统,根据矫直机系统的控制要求,使用软件组态和Profibus-DP总线通信,设置直流调速器的关键参数,实现PLC与直流调速器的通信。通过Step7软件编写对直流调速器的主要控制程序和参数设定程序,设定相关参数,保证矫直机的矫直速度调节的同步性和平滑性。实践证明,该控制系统操作方便、运行稳定可靠。
An electrical control system was designed in Siemens 6RA70 series DC governor and PLC. According to the control requirement, the software was used in the communication mode of Profibus-DP and key parameters of DC governor to solve communication between PLC and DC governor. S7-300 software was used on the control and parameters setup program. The related parameter setup approach was discussed to ensure the synchronization and smoothness of the straightener. It was proved that this proposed system was easy-to-use and stable.
