1 开关电源损坏
这是众多变频器最常见的故障,通常是由于开关电源的负载发生短路造成的,丹佛斯变频器采用了新型脉宽集成控制器UC2844来调整开关电源的输出,同时UC2844还带有电流检测,电压反馈等功能,当发生无显示,控制端子无电压,DC12V,24V风扇不运转等现象时我们首先应该考虑是否开关电源损坏了。
2 SC故障
SC故障是安川变频器较常见的故障。IGBT模块损坏,这是引起SC故障报警的原因之一。此外驱动电路损坏也容易导致SC故障报警。安川在驱动电路的设计上,上桥使用了驱动光耦PC923,这是专用于驱动IGBT模块的带有放大电路的一款光耦,安川的下桥驱动电路则是采用了光耦PC929,这是一款内部带有放大电路,及检测电路的光耦。此外电机抖动,三相电流,电压不平衡,有频率显示却无电压输出,这些现象都有可能是IGBT模块损坏。IGBT模块损坏的原因有多种,首先是外部负载发生故障而导致IGBT模块的损坏如负载发生短路,堵转等。其次驱动电路老化也有可能导致驱动波形失真,或驱动电压波动太大而导致IGBT损坏,从而导致SC故障报警。
3 GF—接地故障
接地故障也是平时会碰到的故障,在排除电机接地存在问题的原因外,最可能发生故障的部分就是霍尔传感器了,霍尔传感器由于受温度,湿度等环境因数的影响,工作点很容易发生飘移,导致GF报警。
4 限流运行
在平时运行中我们可能会碰到变频器提示电流极限。对于一般的变频器在限流报警出现时不能正常平滑的工作,电压(频率)首先要降下来,直到电流下降到允许的范围,一旦电流低于允许值,电压(频率)会再次上升,从而导致系统的不稳定。丹佛斯变频器采用内部斜率控制,在不超过预定限流值的情况下寻找工作点,并控制电机平稳地运行在工作点,并将警告信号反馈客户,依据警告信息我们再去检查负载和电机是否有问题。
