陜西商洛57C410兼配套電源
基本參數(shù)： 19＂SXGA TFT LCD超薄平板電腦、Intel Pentium M低功耗處理器、觸摸屏

12 系統(tǒng)出現(xiàn)VRDY ON 報警 系統(tǒng)在PRDY信號還未發(fā)出就已經(jīng)檢測到VRDY信號。即伺服單元比系統(tǒng)早準(zhǔn)備好，系統(tǒng)認(rèn)為這樣為異常。
陜西商洛57C410兼配套電源
一個開關(guān)有三個按鈕，控制三個電燈，如何接線？開關(guān)上有三排孔排是L1a，L1b,L1c第二排是L0L0L0c，第三排是L2L2L2c，現(xiàn)有兩根白線一根黃線，應(yīng)該怎么接線呢？開關(guān)的L1L1L1c是封著的，不能接線。如果把一根白線和黃線接到L0a上，把另外一根白線接在L2a的左端，結(jié)果有一盞燈是正常的另外一盞從合閘開始就亮著，不受開關(guān)控制，這是怎么回事？答：三個開關(guān)控制三盞燈（每個開關(guān)控制一個燈），首先要有4根線才可以完成，一根電源線，接到三個開關(guān)的進(jìn)線端（L0L0L0C，也就是說用進(jìn)線把這三個點連在一起),把剩下的三根分別接到L2L2L2C，如果現(xiàn)在只有三根線，黃的可能是進(jìn)線，白的就是2個燈的回路線，空著的就說明那個開關(guān)沒有控制任何燈。
1 直流可控硅伺服單元 只有單軸結(jié)構(gòu)，型號為A06B-6045-HXXX。主回路有2個可控硅模塊組成（國產(chǎn)的為6只可控硅），120V三相交流電輸入，六路可控硅全波整流，接觸器，三只�？刂齐娐钒逵袃煞N，帶電源和不帶電源，其作用是接受系統(tǒng)的速度指令（0-10V模擬電壓），和速度反饋信號，給主回路提供六路觸發(fā)脈沖。 配早期系統(tǒng)，如：5，7，330C，200C，2000C等。市場上已不常見。

1圖是漏電開關(guān)的零序電流互感器鐵芯，可以看到火線和零線同時穿過鐵芯。2圖中的T是變壓器，變壓器有兩個原邊繞組，一個副邊繞組。其中兩個原邊繞組線圈的纏繞方向一致，圈數(shù)也相等。當(dāng)原邊繞組1中流過電流I1時，按右手螺旋定則判斷出變壓器鐵芯中的磁力線方向。請注意，2圖中變壓器T的原邊繞組1和原邊繞組2的電流方向是相反的，按右手螺旋定則，如果電流I1與I2大小相等方向相反，則變壓器鐵芯中沒有磁力線，副邊繞組當(dāng)然也不會出現(xiàn)感應(yīng)電流和感應(yīng)電壓。
● 內(nèi)置2K容量的EEPROM存儲器,無需電池,免維護(hù)

嚴(yán)格來講，編碼器只會告訴你改如何定位，要如何執(zhí)行，是需要靠數(shù)控系統(tǒng)（或者plc之類控制器）控制伺服或者步進(jìn)電機來實現(xiàn)定位的，編碼器好比人的眼睛，知道電機軸或者負(fù)載處于當(dāng)前某個位置，工業(yè)上用的一般是光電類型編碼器，下邊簡單說明一下。簡單說下編碼原理和位置測量光電編碼器是在一個很薄很輕的圓盤子上，通過緊密儀器來腐蝕雕刻了很多條細(xì)小的縫，相當(dāng)于把一個360度，細(xì)分成很多等分，比如成1024組，這樣每組之間的角度差是360/1024度=0.3515625度。
