執(zhí)行程序在執(zhí)行用戶程序過程中,PLC按梯形圖程序順序自上而下、從左至右逐個(gè)掃描執(zhí)行,即按助記符指令表的先后順序執(zhí)行。但遇到程序跳轉(zhuǎn)指令,則根據(jù)跳轉(zhuǎn)條件是否滿足來決定程序跳轉(zhuǎn)地址。
根據(jù)變頻器發(fā)生故障或損壞的特征,一般可分為兩類;一種是在運(yùn)行中頻繁出現(xiàn)的自動(dòng)停機(jī)現(xiàn)象,并伴隨著一定的故障顯示代碼,其處理措施可根據(jù)隨機(jī)說明書上提供的指導(dǎo)方法,進(jìn)行處理和解決。
口訣是現(xiàn)場(chǎng)快速求算電動(dòng)機(jī)空載電流具體數(shù)值的口訣,它是眾多的測(cè)試數(shù)據(jù)而得。它符合"電動(dòng)機(jī)的空載電流一般是其額定電流的1/3"。同時(shí)它符合實(shí)踐經(jīng)驗(yàn):"電動(dòng)機(jī)的空載電流,不超過容量千瓦數(shù)便可使用"的原則(指檢修后的舊式、小容量電動(dòng)機(jī))??谠E"容量八折左右求"是指一般電動(dòng)機(jī)的空載電流值是電動(dòng)機(jī)額定容量千瓦數(shù)的0.8倍左右。中型、4或6極電動(dòng)機(jī)的空載電流,就是電動(dòng)機(jī)容量千瓦數(shù)的0.8倍;新系列,大容量,極數(shù)偏小的2級(jí)電動(dòng)機(jī),其空載電流計(jì)算按"新大極數(shù)少六折";對(duì)舊的、老式系列、較小容量,極數(shù)偏大的8極以上電動(dòng)機(jī),其空載電流,按"是小極多千瓦數(shù)"計(jì)算,即空載電流值近似等于容量千瓦數(shù),但一般是小于千瓦數(shù)。運(yùn)用口訣計(jì)算電動(dòng)機(jī)的空載電流,算值與電動(dòng)機(jī)說明書標(biāo)注的、實(shí)測(cè)值有一定的誤差,但口訣算值完全能滿足電工日常工作所需求。
在圖中可顯示出電氣設(shè)備中各元件的空間位置和接線情況,可在安裝或檢修時(shí)對(duì)照原理圖使用。它是根據(jù)電器位置布置依合理經(jīng)濟(jì)等原則安排的,它表示機(jī)床電氣設(shè)備各個(gè)單元之間的接線關(guān)系,并標(biāo)注出外部接線所需的數(shù)據(jù)。

高壓電器用于交流電壓1200V、直流電壓1500V及以上電路中的電器。例如高壓斷路器、高壓隔離開關(guān)、高壓熔斷器等。低壓電器用于交流50Hz(或60Hz),額定電壓為1200V以下;直流額定電壓1500V及以下的電路中的電器。例如接觸器、繼電器等。按動(dòng)作原理分類手動(dòng)電器用手或依靠機(jī)械力進(jìn)行操作的電器,如手動(dòng)開關(guān)、控制按鈕、行程開關(guān)等主令電器。自動(dòng)電器借助于電磁力或某個(gè)物理量的變化自動(dòng)進(jìn)行操作的電器,如接觸器、各種類型的繼電器、電磁閥等
變頻器的SVPWM控制方式是以三相波形整體生成效果為前提,以逼近電機(jī)氣隙的理想圓形旋轉(zhuǎn)磁場(chǎng)軌跡為目的,一次生成三相調(diào)制波形,以內(nèi)切多邊形逼近圓的方式進(jìn)行控制的。經(jīng)實(shí)踐使用后又有所改進(jìn),即引入頻率補(bǔ)償,能消除速度控制的誤差;通過反饋估算磁鏈幅值,消除低速時(shí)定子電阻的影響;將輸出電壓、電流閉環(huán),以提高動(dòng)態(tài)的精度和穩(wěn)定度。
接觸器的線圈電壓,一般應(yīng)低一些為好,這樣對(duì)接觸器的絕緣要求可以降低,使用時(shí)也較安全。但為了方便和減少設(shè)備,常按實(shí)際電網(wǎng)電壓選取。
