從鍵盤輸入數(shù)碼信號(hào)，是通過編碼掃描程序進(jìn)入cpu系統(tǒng)，控制端子輸入的模擬信號(hào)則是經(jīng)過a/d轉(zhuǎn)換后并經(jīng)邏輯電路處理進(jìn)入cpu系統(tǒng)。通過排斥法和比較法的檢測，可以確認(rèn)a/d轉(zhuǎn)換電路正常。

硬件完好，那只能在軟件上存在問題。從芯片l7300526a工作方式可知，該芯片采用數(shù)字雙邊沿調(diào)制載波方式產(chǎn)生脈寬調(diào)制信號(hào)，驅(qū)動(dòng)晶體管功率模塊構(gòu)成的三相逆變器。載波頻率等于輸出頻率和載波倍數(shù)的乘積。

對(duì)于載波倍數(shù)的每個(gè)值，芯片內(nèi)部的譯碼器都保存一組相應(yīng)的δ值(δ值是一個(gè)可調(diào)的時(shí)間間隔量，用于調(diào)制脈沖邊沿)。每個(gè)δ值都是以數(shù)字形式存儲(chǔ)，與它相應(yīng)的脈沖調(diào)制寬度由對(duì)應(yīng)數(shù)值的計(jì)數(shù)速率所確定。譯碼器根據(jù)載波頻率和δ調(diào)制，產(chǎn)生3個(gè)控制信號(hào)，每個(gè)輸出級(jí)分配1個(gè)，它們彼此相差120°相位角。616p5的載波參數(shù)n050設(shè)定的載波變化區(qū)間分別是[1、2、4～6]、[8]、[7～9]。根據(jù)616p5的載波參數(shù)n050的含義，重新核查載波設(shè)置值，結(jié)果發(fā)現(xiàn)屏顯輸出的是一個(gè)非有效值“10”且不可調(diào)(616p5載波變化區(qū)間的有效值應(yīng)為1-9)。由此可見“屏顯輸出50hz不可變”的故障顯然與載波倍數(shù)的δ有關(guān)。載波調(diào)制功能的正常與否直接影響功率晶體管開關(guān)頻率的變化，從而影響輸出電壓(即頻率)的變化。修改該參數(shù)后故障。
