36、lthhappyhappy332PLC的每一個(gè)掃描過(guò)程分為三個(gè)階段，分別是：_、_和_三個(gè)階段。33機(jī)床中最常見的降壓起動(dòng)方法有__、_和_降壓起動(dòng)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(chǔ)器，用來(lái)在內(nèi)部存儲(chǔ)執(zhí)行_、_、_、_和算術(shù)運(yùn)算等操作的指令，并通過(guò)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(guò)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(gè)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(gè)，其中輸入點(diǎn)的點(diǎn)號(hào)從_到_，輸出點(diǎn)的點(diǎn)號(hào)從_到_。35機(jī)床上常用的電氣制動(dòng)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(dòng)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(guò)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(dòng)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(hào)，當(dāng)線圈反映電壓信號(hào)時(shí)，為_繼電器；當(dāng)線圈反映電流信號(hào)時(shí)，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(shí)，禁止全
