即上電試機。在上電前后必須注意以下幾點：上電之前，須確認(rèn)輸入電壓是否有誤，將380V電源接入220V級變頻器之中會出現(xiàn)炸機（炸電容、壓敏電阻、模塊等）；檢查變頻器各接插口是否已正確連接，連接是否有松動，連接異常有時可能會導(dǎo)致變頻器出現(xiàn)故障，嚴(yán)重時會出炸機等情況；上電后檢測故障顯示內(nèi)容，并初步斷定故障及原因；如未顯示故障，首先檢查參數(shù)是否有異常，并將參數(shù)復(fù)歸后，在空載（不接電機）情況下啟動變頻器，并測試U、V、W三相輸出電壓值。如出現(xiàn)缺相、三相不平衡等情況，則模塊或驅(qū)動板等有故障；在輸出電壓正常（無缺相、三相平衡）的情況下，負(fù)載測試，盡量是滿負(fù)載測試。[1]故障判斷整流模塊損壞通常是由于電網(wǎng)電壓或內(nèi)部短路引起。

控制極G通過按鈕開關(guān)SB接在1.5V直流電源的正極（這里使用的是KP1型晶閘管，若采用KP5型，應(yīng)接在3V直流電源的正極）。晶閘管與電源的這種連接方式叫做正向連接，也就是說，給晶閘管陽極和控制極所加的都是正向電壓。合上電源開關(guān)S，小燈泡不亮，說明晶閘管沒有導(dǎo)通；再按一下按鈕開關(guān)SB，給控制極輸入一個觸發(fā)電壓，小燈泡亮了，說明晶閘管導(dǎo)通了。這個演示實驗給了我們什么啟發(fā)呢?這個實驗告訴我們，要使晶閘管導(dǎo)通，一是在它的陽極A與陰極K之間外加正向電壓，二是在它的控制極G與陰極K之間輸入一個正向觸發(fā)電壓。晶閘管導(dǎo)通后，松開按鈕開關(guān)，去掉觸發(fā)電壓，仍然維持導(dǎo)通狀態(tài)。晶閘管特點“一觸即發(fā)”。但是，如果陽極或控制極外加的是反向電壓。

1.比較器檢測通過穩(wěn)壓管固定比較器一端的電壓，被檢測的電壓取樣后再與之比較，結(jié)果通過比較器輸出。2.ADC檢測(模擬/數(shù)字轉(zhuǎn)換器)被檢測的電壓通過電阻降壓取樣后，落在ADC可檢測的范圍，可以通過程序設(shè)定電壓的報警范圍。主電路中的儲能電容，對運行中變頻器過壓、欠壓影響很大。而變頻器電路的各種零部件又有一定使用壽命的，所以一旦變頻器零部件達到使用壽命就會帶來故障的發(fā)生。像主電路中的儲能電容或其它零部件的原因都有可能對主電路造成影響，從而使整個變頻器發(fā)生故障。通常變頻器停用時間過長，達到一年以上，則應(yīng)對儲能電容要做一次體檢。對長時間不用的變頻器，如何來避免這種現(xiàn)象發(fā)生呢?按照要求，停用的變頻器應(yīng)每隔兩三個月通電—次。
