變頻器在停止一段時間未使用后，再次啟動時，很多用戶反應變頻器一上電會出現變頻器燒主板或者變頻器爆模塊的情況。變頻器維修中這種情況發生的可能原因： 1、電機因慣性運轉產生回電，變頻器主輸出電路與控制線路未及時或者完全隔絕開來，導致變頻器主板或者模塊燒壞，這是在成套電氣設備設計之初未能完全考慮變頻器的工作環境導致的結果。 解決辦法是：電機停止時斷開變頻器后的接觸器，如果有可能增加電機剎車抱閘機構。從而解決電機慣性運轉產生的方向空載電壓。 2、強電的干擾導致電路板和模塊燒壞，具體原因是主電路與控制電路相隔較近，因為電流的諧同作用，主電路中一旦有瞬間的高電壓出現，會使控制電路電壓或者電流過載，從而燒壞電氣元件。 解決辦法是：變頻器在設計時充分考慮主電路對控制電路的干擾作用，盡量避免或降至，輸入主電路采用保護措施，避免大電流對變頻器的沖擊。 3、陰雨天氣被雷擊也有可能導致變頻器損壞，原因也是過高的輸入電壓導致的。
