在使用變頻器過程中，經(jīng)常會(huì)碰到變頻器無輸出現(xiàn)象。驅(qū)動(dòng)電路損壞、逆變模塊損壞都有可能引起變頻器無輸出，此外輸出反饋電路出現(xiàn)故障也能引起此類故障現(xiàn)象。有時(shí)在實(shí)際中遇到變頻器有輸出頻率，沒有輸出電壓(實(shí)際輸出電壓非常小，可認(rèn)為無輸出)，這時(shí)則應(yīng)考慮一下是否是反饋電路出現(xiàn)了故障所致。在反饋電路中用于降壓的反饋電阻是較容易出現(xiàn)故障的元件之一；檢測電路的損壞也是導(dǎo)致變頻器顯示OC(+pA或+pd或+pn)保護(hù)功能動(dòng)作的原因，檢測電流的霍爾傳感器由于受溫度，濕度等環(huán)境因素的影響，工作點(diǎn)容易發(fā)生飄移，導(dǎo)致OC報(bào)警。
（注意，正因?yàn)槿绱?，所以變頻器的產(chǎn)生便是在這個(gè)背景下的）。20世紀(jì)70年代開始，脈寬調(diào)制變壓變頻(PWM－VVVF)調(diào)速研究引起了人們的高度重視。20世紀(jì)80年代，作為變頻技術(shù)核心的PWM模式優(yōu)化問題吸引著人們的濃厚興趣，并得出諸多優(yōu)化模式，其中以鞍形波PWM模式效果最佳。

接地過電流保護(hù)。逆變器負(fù)載側(cè)接地設(shè)計(jì)，為了保護(hù)逆變器，有時(shí)要有接地過電流保護(hù)功能。但為了確保人身安全，需要裝設(shè)漏電斷路器。冷卻風(fēng)機(jī)異常。有冷卻風(fēng)機(jī)的裝置，當(dāng)風(fēng)機(jī)異常時(shí)裝置內(nèi)的溫度將上升。因此采用風(fēng)機(jī)熱繼電器或器件散熱片傳感器，檢出異常后停止逆變器。
編程器是PLC必不可少的重要外部設(shè)備。編程器將用戶所希望的功能通過編程語言送到PLC的用戶程序存儲(chǔ)器中。編程器不僅能對(duì)程序進(jìn)行寫入、讀出、修改，還能對(duì)PLC的工作狀態(tài)進(jìn)行監(jiān)控，同時(shí)也是用戶與PLC之間進(jìn)行人機(jī)對(duì)話的界面。隨著PLC的功能不斷增強(qiáng)，編程語言多樣化，編程已經(jīng)可以在計(jì)算機(jī)上完成。
分析設(shè)計(jì)法是根據(jù)生產(chǎn)工藝的要求選擇適當(dāng)?shù)幕究刂骗h(huán)節(jié)（單元電路）或?qū)⒈容^成熟的電路按其聯(lián)鎖條件組合起來，并經(jīng)補(bǔ)充和修改，將其綜合成滿足控制要求的完整線路。當(dāng)沒有現(xiàn)成的典型環(huán)節(jié)時(shí)，可根據(jù)控制要求邊分析邊設(shè)計(jì)。
