SB60G型变频器故障分析和检修方法

The Failure Analysis and Repair Methods of SB60G Inverter

变频器控制系统常见的故障类型主要有过电流、短路、接地、过电压、欠电压、电源缺相、变频器内部过热、变频器过载、电动机过载、CPU异常、通信异常等,当发生这些故障时,变频器保护会立即动作并停机,并显示故障代码或故障类型,大多数情况下可以根据显示的故障代码迅速找到故障原因并排除故障。但也有一些故障的原因是多方面的,并不是由单一原因引起的,因此需要从多个方面查找,逐一排除才能找到故障点。

Inverter control system for common types of failure are mainly over-current, short circuit, grounding, over-voltage, under-voltage, power shortage phase inverter internal overheating, inverter overload, motor overload, CPU abnormal abnormalities, such as communication, when the occurrence of such failure, inverter will immediately move to protect and downtime, and display the fault code or fault types, the majority of cases shows that the fault can quickly find the cause of the malfunction code and troubleshooting. But there are also some of the reasons for failure are many, not by a single cause, and therefore need to find a number of fronts, one by one rule out the possibility to find a poi.
