1；检查电动机时否发热，如果电动机温升不高，则应先检查变频器的电子热保护功能设置得是否合理。如变频器尚有裕量，则应调大电子热保护功能的预设值。
如果电动机的温升过高，这时的过载是属于正常过载，则说明是电动机负荷过重。这时，首先应看能否适当加大传动比，以减轻电动机轴上的负荷。如能够加大，则加大传动比；如果传动比无法加大，则应加大电动机的容量。
2；检查电动机侧三相电压是否平衡，如果电动机侧的三相电压不平衡，则应再检查变频器输出端的三相电压是否平衡，如果也不平衡，则问题在变频器内部发生故障，就必须对变频器维修。
如果电动机侧三相电压平衡，则应了解跳闸时的工作频率。如果工作频率较低，又未用矢量控制（或无矢量控制），则首先降低V/f比。如果降低后仍能带动负载，则说明原来设置的V/f比过高，励磁电流的峰值偏大，可通过降低V/f比来减小电流；如果降低后带不动负载了，则应考虑加大变频器的容量；如果变频器有矢量控制功能，则应采用矢量控制方式。
