36、lthhappyhappy332PLC的每一個掃描過程分為三個階段，分別是：_、_和_三個階段。33機(jī)床中最常見的降壓起動方法有__、_和_降壓起動三種。34可編程序控制器是一種數(shù)字運(yùn)算的電子系統(tǒng)，專為_環(huán)境下應(yīng)用而設(shè)計(jì)。它用可編程的存儲器，用來在內(nèi)部存儲執(zhí)行_、_、_、_和算術(shù)運(yùn)算等操作的指令，并通過數(shù)字式、模擬式的輸入和輸出，控制各種類型的機(jī)械或生產(chǎn)過程?？删幊炭刂破骷捌溆嘘P(guān)設(shè)備，都應(yīng)按易于與工業(yè)控制系統(tǒng)聯(lián)成一個整體，易于擴(kuò)充的原則

37、設(shè)計(jì)。35FX2N48MR型可編程序控制器，共有輸入_輸出點(diǎn)_個，其中輸入點(diǎn)的點(diǎn)號從_到_，輸出點(diǎn)的點(diǎn)號從_到_。35機(jī)床上常用的電氣制動控制線路有兩種即__和_。36ＰＬＣ的英文全稱是_。37觸頭的結(jié)構(gòu)形式有_、_。38接觸器用于遠(yuǎn)距離頻繁地接通或斷開交直流_及大容量控制電路的一種自動開關(guān)電器。39接觸器的額定通斷能力是指其主觸頭在規(guī)定條件下可靠地_的電流值。40繼電器是一種利用各種物理量的變化，將_的變化轉(zhuǎn)化為電磁力或使輸出狀態(tài)發(fā)生

38、階躍變化，從而通過其觸頭或突變量促使在同一電路或另一電路中的其他器件或裝置動作的一種控制元件。41繼電器的調(diào)節(jié)裝置用以改變繼電器的_。42低壓電器按用途分：_、_等。43電磁式繼電器反映的是電信號，當(dāng)線圈反映電壓信號時，為_繼電器；當(dāng)線圈反映電流信號時，為_繼電器。44電磁式電壓繼電器線圈_在電路電壓上，用于反映電路電壓大小。45電磁式電流繼電器線圈在電路中，用于反映電路_的大小。46.FX系列PLC的特殊功能繼電器的線圈通電時，禁止全
