过流故障

过流故障可分为加速、减速、恒速过电流。其可能是由于变频器的加减速时间太短、负载发生突变、负荷分配不均，输出短路等原因引起的。这时一般可通过延长加减速时间、减少负荷的突变、外加能耗制动元件、进行负荷分配设计、对线路进行检查。如果断开负载变频器还是过流故障，说明变频器逆变电路已环，需要更换变频器。

过载故障

过载故障包括变频过载和电机过载。其可能是加速时间太短，电网电压太低、负载过重等原因引起的。一般可通过延长加速时间、延长制动时间、检查电网电压等。负载过重，所选的电机和变频器不能拖动该负载，也可能是由于机械润滑不好引起。如前者则必须更换大功率的电机和变频器；如后者则要对生产机械进行检修。
