故障診斷的任務是確定故障的性質(zhì)，查出產(chǎn)生故障的原因和部位，以便迅速處理排除故障，恢復其功能，及時投入運行。在診斷過程中應借助一些儀器儀表和變頻器自診斷系統(tǒng)綜合分析。

1、故障診斷的過程

詢問用戶變頻器的故障現(xiàn)象和查看變頻器指示等情況，包括故障發(fā)生前后外部環(huán)境的變化。例如，電源的異常波動、負載的變化等。

根據(jù)用戶的故障描述，分析可能造成此類故障的原因。

打開被維修的設備，確認被損壞的部位，分析維修恢復的可行性。

根據(jù)被損壞器件的工作位置，通過閱讀電路，分析電路工作原理，從中找出損壞器件的原因，以及一些相關(guān)的電子電路。

尋找相關(guān)的器件進行替換。

在確定所有可能造成故障，所有原因都排除的情況下，通電進行實驗，在做這一步檢查的時候，一般要求所有的外部條件都具備，并且不會引起故障的進一步擴大。

在檢修設備工作正常的情況下，就可以進入系統(tǒng)測試。
