變頻器工作正常。變頻器操作手冊(cè)上的故障對(duì)策表中介紹的皆為較常見的故障,在出現(xiàn)未涉及的一些的代碼時(shí)應(yīng)對(duì)變頻器作檢查。(6)MM420/MM440變頻器的AOP面板僅能存儲(chǔ)一組參數(shù)變頻器選型手冊(cè)中介紹AOP面板中能存儲(chǔ)10組參數(shù),但在用AOP面板作第二臺(tái)變頻器參數(shù)的備份時(shí),顯“存儲(chǔ)容量不足”。解決辦法如下:a)在菜單中選擇“語言”項(xiàng);b)在“語言”項(xiàng)中選擇一種不使用的語言;c)按Fn+Δ鍵選擇刪除,經(jīng)提示后按P鍵確認(rèn);這樣,AOP面板就可存儲(chǔ)10組參數(shù)。造成這種現(xiàn)象的原因可能是設(shè)計(jì)時(shí)AOP面板中的內(nèi)存不夠。(7)ABBACS600變頻器在運(yùn)行時(shí)直流回路過壓跳閘該變頻器配置有制動(dòng)斬波器和制動(dòng)電阻,但外方調(diào)試人員在調(diào)試時(shí)將電壓控制器選擇為ON而未使用制動(dòng)斬波器和制動(dòng)電阻。
