鄭州一級(jí)代理FR-E720-7.5K-CHT型號(hào)
漳州代理變頻器FR-E720-11K-CHT廠家
常見(jiàn)系列產(chǎn)品故障
市場(chǎng)上正在推廣使用的就是A700系列、E700系列、F700系列和D700系列。
（1）對(duì)于A700系列，有時(shí)會(huì)碰到UV（欠壓）故障，可以檢查一下整流回路。A700系列7.5kW以下變頻器的整流橋內(nèi)置一個(gè)可控硅，變頻器在正常運(yùn)行時(shí)用于切斷充電電阻，內(nèi)置可控硅的損壞會(huì)導(dǎo)致欠壓故障的出現(xiàn)。開(kāi)關(guān)電源損壞也是A700系列變頻器的常見(jiàn)故障，而常見(jiàn)的損壞器件就是一塊M51996波形發(fā)生器芯片，此芯片的損壞通常是由于工作電壓的突變而導(dǎo)致的。較容易出現(xiàn)問(wèn)題的地方主要有芯片14腳的電源，調(diào)整電壓基準(zhǔn)值的7腳，反饋檢測(cè)的5腳，以及波形輸出的2腳等。此外，在平時(shí)維修中，還會(huì)經(jīng)常碰到CPU板的損壞。常見(jiàn)的故障報(bào)警有E6、E7，而損壞器件也主要集中在CPU板的程序存儲(chǔ)芯片，以及一些接口芯片上。
