摘要
介绍了堆取料机驱动回转机构上使用的MM440变频器,对变频器故障代码进行分析,围绕变频器的过电压故障报警进行排查,找出由于环境情况的变化而引起的回转用变频器的故障原因。通过调整变频器参数,增加改变专用电机启动过程的动力特性,使故障得到排除。
This paper introduced the MM440 inverter used in the stacker driving rotary mechanism, analyzed its fault code, investigated the overvoltage fault alarms of the inverter and found out that a change in environmental conditions of the rotary inverter caused the fault. By adjusting the parameters of the transducer and changing the dynamic characteristics of the startup process of the special motor, the fault was eliminated.
