摘要
为远程控制采煤机牵引变频器ACS800搭建了基于STEP7的现场总线监控系统。研究了现场总线上主站与变频器现场适配器的通讯报文,分配了变频器收发区地址,并规划了通讯报文中参数通道(PKW)和过程通道(PZD)的内容。结合变频器通信程序流程图,编写了变频器起停控制程序。实现了远程控制牵引电机的动作。
In order to control and monitor shearer haulage frequency converter ACSS00,the llelcl bus system based on STEP7 has been set up. Research on parameter process object message between main bus and frequency converter, allocate sending and receiving address, furthermore, plan content in PKW and PZD of message. According to flow chart of frequency converter communication programming, starting and stopping program has been designed. The system could remotely control haulage motor.
