MM430报故障，绿灯和黄灯来回跳，变频器不工作

• MM440/430/420/410

报故障，绿灯和黄灯来回跳，变频器不工作

最佳答案

1、你的绿灯和黄灯的闪烁情况不同，其代表的具体含义也不同。现说明如下。

2、两个LED灯以1S的频率， 同时闪光：代表电流极限报警；

     两个LED灯以1S的频率， 交替闪光：代表存在其它报警；

     两个LED灯以0.3S的频率， 同时闪光：代表变频器ROM 故障；

     两个LED灯以0.3S的频率， 交替闪光：代表变频器RAM 故障；

     绿灯以1S频率闪烁，黄灯以0.3S频率闪烁：代表欠电压跳闸 / 欠电压报警；

     绿灯以0.3S频率闪烁，黄灯以1S频率闪烁：代表变频器不在准备状态。

       你对照上述说明，来看看吧。
