1.8.3 压敏电阻问题
压敏电阻本来是用于进线侧吸收进线过电压的保护器件，但当进线侧电压持续较高，压敏电阻性能有变化时，有可能使压敏电阻爆炸烧毁，同样有可能殃及周围器件和导线绝缘。
1.8.4 电解电容器漏液、爆炸、燃烧
电解电容质量不好的表现有：漏液、漏电流大、损耗大、发热、鼓包、炸裂、由炸裂引起燃烧、容量下降，内阻及电感增加。对于滤波用电解电容器因电压高、容量大，所储存的能量大，容易造成漏液、爆炸、燃烧。电解液是可燃物，可造成燃烧事故。因此要用质量好的电解电容器，并在到达寿命前更换新的。
1.9 常见运行中的故障
1.9.1 过电流跳闸
起动时，一升速就跳闸，说明过电流十分严重，应查看有否负载短路、接地、工作机械卡堵、传动损坏、电动机起动转矩过小、以及根本起不动、变频器逆变桥已损坏。
运行中跳闸引起的原因有升速设定时间过短、降速时间设定过短、转矩补偿（V/f 比）设定太大，造成低速过电流、热继电器调整不当，动作电流设定太小也可引起过电流动作。
1.9.2 过电压和欠电压跳闸
（1）过电压：电源电压过高、降速时间设定过短、降速过程中制动单元没有工作或制动单元放电太慢，即制动电阻太大。变频器内部过电压保护电路有故障会引起过电压。
（2）欠电压：电源电压过低、电源缺相、整流桥有一相故障，变频器内部欠电压保护电路故障也会引起欠电压。
1.9.3 电动机不转
电动机、导线、变频器有损坏，线未接好，功能设置，如上限频率、下限频率、最高频率设定时没有注意，相互矛盾着。使用外控给定时，没有选项预置，以及-不合理设置。
