基于PLC网络控制技术的珩磨机运动控制

摘要

根据珩磨机床加工工艺原理和控制要求,构建了基于RS -485的主从式控制网络.通过该网络主站PLC对各从站伺服驱动器、变频器等的运行实施监控.介绍了伺服驱动器及变频器的通信协议,给出了PLC与伺服驱动器、变频器间的通信方法.%According to the process principle and control requirements for honing machine, a control network was formed based on RS—485 master—slave structure. By using the control network, PLC (master) could monitor and control servo driver and transducer (slave). This paper introduces the communication protocols between servo driver and transducer. A description of the serial communication between PLC and servo driver and transducer were presented.
