編碼器(qi)實(shi)現伺服控制的方式如下：

編(bian)(bian)(bian)碼(ma)(ma)器(qi)(qi)在(zai)伺(si)服(fu)(fu)(fu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)中(zhong)(zhong)，主要(yao)起的(de)(de)是反饋(kui)作用(yong)，也就是將電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)速(su)度(du)、位(wei)置等(deng)參(can)(can)數(shu)檢(jian)測(ce)出來(lai)，然后輸入到伺(si)服(fu)(fu)(fu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)(qi)中(zhong)(zhong)，控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)(qi)根據這些(xie)(xie)參(can)(can)數(shu)，判斷電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)運(yun)(yun)(yun)行狀(zhuang)(zhuang)(zhuang)態，進而(er)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)轉動。具體來(lai)說，編(bian)(bian)(bian)碼(ma)(ma)器(qi)(qi)可(ke)以將電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)速(su)度(du)、位(wei)置等(deng)參(can)(can)數(shu)檢(jian)測(ce)出來(lai)，然后通過(guo)編(bian)(bian)(bian)碼(ma)(ma)器(qi)(qi)將它(ta)們轉換成脈(mo)沖信號(hao)(hao)，這些(xie)(xie)脈(mo)沖信號(hao)(hao)再被(bei)輸入到伺(si)服(fu)(fu)(fu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)(qi)中(zhong)(zhong)。伺(si)服(fu)(fu)(fu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)(qi)根據這些(xie)(xie)脈(mo)沖信號(hao)(hao)，判斷電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)運(yun)(yun)(yun)行狀(zhuang)(zhuang)(zhuang)態，比如是否超速(su)、是否過(guo)載等(deng)，然后根據這些(xie)(xie)狀(zhuang)(zhuang)(zhuang)態信息(xi)，控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)轉動。在(zai)這個過(guo)程中(zhong)(zhong)，編(bian)(bian)(bian)碼(ma)(ma)器(qi)(qi)起到了一個反饋(kui)的(de)(de)作用(yong)，它(ta)讓伺(si)服(fu)(fu)(fu)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)器(qi)(qi)能夠實時掌握電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)運(yun)(yun)(yun)行狀(zhuang)(zhuang)(zhuang)態，進而(er)實現精確的(de)(de)控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)。伺(si)服(fu)(fu)(fu)電(dian)(dian)機(ji)(ji)(ji)(ji)的(de)(de)應用(yong)在(zai)電(dian)(dian)氣控(kong)(kong)制(zhi)(zhi)(zhi)(zhi)中(zhong)(zhong)運(yun)(yun)(yun)用(yong)很普遍(bian)。英威騰MH860伺(si)服(fu)(fu)(fu)電(dian)(dian)機(ji)(ji)(ji)(ji)說明(ming)書(shu)

伺(si)服(fu)電(dian)機需(xu)要搭(da)配減(jian)(jian)(jian)速(su)(su)機一起使(shi)用。伺(si)服(fu)電(dian)機一般用于高精度(du)、高速(su)(su)、高速(su)(su)度(du)控制等方面(mian)，但(dan)在(zai)重(zhong)負載(zai)(zai)的情況下(xia)，伺(si)服(fu)電(dian)機需(xu)要輸(shu)出(chu)(chu)較(jiao)大的轉(zhuan)(zhuan)矩(ju)(ju)，而通常(chang)情況下(xia)輸(shu)出(chu)(chu)的轉(zhuan)(zhuan)矩(ju)(ju)不足(zu)(zu)(zu)以(yi)滿足(zu)(zu)(zu)重(zhong)負載(zai)(zai)下(xia)的要求。因此，為了(le)滿足(zu)(zu)(zu)重(zhong)載(zai)(zai)時的需(xu)求，通常(chang)需(xu)要將伺(si)服(fu)電(dian)機和減(jian)(jian)(jian)速(su)(su)電(dian)機相結合(he)使(shi)用，通過減(jian)(jian)(jian)速(su)(su)箱減(jian)(jian)(jian)小輸(shu)出(chu)(chu)功(gong)率，提(ti)高輸(shu)出(chu)(chu)扭(niu)矩(ju)(ju)，從而滿足(zu)(zu)(zu)所需(xu)的輸(shu)出(chu)(chu)轉(zhuan)(zhuan)矩(ju)(ju)。此外，減(jian)(jian)(jian)速(su)(su)電(dian)機還(huan)可以(yi)提(ti)高伺(si)服(fu)電(dian)機的工作效(xiao)率，避免(mian)過載(zai)(zai)或損(sun)壞，并且(qie)還(huan)能(neng)夠提(ti)高系統的響應速(su)(su)度(du)和穩(wen)定(ding)性(xing)。上海(hai)5.5KW伺(si)服(fu)電(dian)機電(dian)流伺(si)服(fu)電(dian)機通常(chang)帶有齒輪(lun)裝(zhuang)置，使(shi)我(wo)們能(neng)夠以(yi)小巧輕(qing)便的封(feng)裝(zhuang)獲得非(fei)常(chang)高的扭(niu)矩(ju)(ju)伺(si)服(fu)電(dian)機。

伺服電(dian)(dian)機(ji)在(zai)(zai)很多(duo)行業(ye)都(dou)有(you)(you)用(yong)到，例(li)如(ru)醫療檢查行業(ye)、食品(pin)包裝行業(ye)、物流(liu)運(yun)輸(shu)(shu)行業(ye)、微電(dian)(dian)子(zi)生(sheng)產(chan)加工、切割(ge)機(ji)器、半(ban)導體設備(bei)、光學設備(bei)、機(ji)床、機(ji)器人、醫療設備(bei)、自動(dong)化生(sheng)產(chan)線等(deng)(deng)1。伺服電(dian)(dian)機(ji)在(zai)(zai)這些行業(ye)中起(qi)到了不可或缺的(de)(de)作用(yong)，例(li)如(ru)在(zai)(zai)醫療檢查行業(ye)中，CT機(ji)、B超機(ji)、核磁共振(zhen)機(ji)等(deng)(deng)設備(bei)的(de)(de)移(yi)動(dong)病人機(ji)構都(dou)有(you)(you)伺服電(dian)(dian)機(ji)在(zai)(zai)做功；在(zai)(zai)食品(pin)包裝行業(ye)中，比如(ru)薯(shu)條等(deng)(deng)零食的(de)(de)真空(kong)包裝生(sheng)產(chan)等(deng)(deng)等(deng)(deng)都(dou)需要用(yong)到伺服電(dian)(dian)機(ji)；在(zai)(zai)物流(liu)運(yun)輸(shu)(shu)行業(ye)中，比如(ru)某東某寶的(de)(de)大型存儲倉(cang)庫中，有(you)(you)很多(duo)的(de)(de)AGV車用(yong)于(yu)貨物的(de)(de)運(yun)輸(shu)(shu)調配，它們就采用(yong)了伺服電(dian)(dian)機(ji)進行移(yi)動(dong)和(he)轉(zhuan)向。

伺(si)服(fu)(fu)電機(ji)(ji)編(bian)(bian)碼(ma)器調(diao)零(ling)(ling)的(de)(de)含(han)義1、伺(si)服(fu)(fu)電機(ji)(ji)的(de)(de)控(kong)制原(yuan)理是(shi)采用矢量控(kong)制方(fang)式來控(kong)制和(he)驅動的(de)(de)，因(yin)(yin)此將編(bian)(bian)碼(ma)器在電機(ji)(ji)軸上(shang)的(de)(de)安(an)裝角(jiao)度稱為零(ling)(ling)點。這里需要(yao)注意的(de)(de)一(yi)(yi)點是(shi)不同系列的(de)(de)伺(si)服(fu)(fu)電機(ji)(ji)其安(an)裝的(de)(de)角(jiao)度值不同。2、伺(si)服(fu)(fu)電機(ji)(ji)零(ling)(ling)點誤差大(da)，電機(ji)(ji)的(de)(de)無功電流也(ye)會增(zeng)大(da)，轉矩(ju)不會隨著電流增(zeng)大(da)而增(zeng)大(da)，因(yin)(yin)此電機(ji)(ji)會表現(xian)無力，也(ye)就是(shi)轉矩(ju)不夠(gou)，甚至出(chu)現(xian)電機(ji)(ji)無法運(yun)行(xing)(xing)的(de)(de)情況(kuang)，一(yi)(yi)般情況(kuang)下，不建議對伺(si)服(fu)(fu)電機(ji)(ji)的(de)(de)編(bian)(bian)碼(ma)的(de)(de)安(an)裝位(wei)置和(he)角(jiao)度進(jin)行(xing)(xing)調(diao)整。3、伺(si)服(fu)(fu)電機(ji)(ji)編(bian)(bian)碼(ma)器調(diao)整零(ling)(ling)位(wei)可以(yi)通過換(huan)編(bian)(bian)碼(ma)器來實現(xian)，如果(guo)要(yao)換(huan)軸承，要(yao)對編(bian)(bian)碼(ma)器進(jin)行(xing)(xing)一(yi)(yi)定的(de)(de)拆除安(an)裝，拆之(zhi)前(qian)對編(bian)(bian)碼(ma)的(de)(de)各部(bu)件座做(zuo)一(yi)(yi)個(ge)簡單的(de)(de)位(wei)點標(biao)記，以(yi)防(fang)安(an)裝不到位(wei)而導致故障出(chu)現(xian)。伺(si)服(fu)(fu)電機(ji)(ji)可用于(yu)會被水或(huo)液(ye)滴侵蝕(shi)的(de)(de)地方(fang)，但(dan)它(ta)不能完(wan)全防(fang)濕或(huo)防(fang)油。

伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)和(he)步(bu)(bu)進電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)是兩種不同類(lei)型(xing)的(de)(de)(de)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)，它們的(de)(de)(de)工作原理、性能(neng)和(he)應用(yong)(yong)場(chang)景都不同。因此(ci)，伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)不能(neng)直接代替(ti)步(bu)(bu)進電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)使用(yong)(yong)。首先，伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)是一種閉環控(kong)(kong)制(zhi)系統，能(neng)夠實(shi)現(xian)精(jing)確(que)的(de)(de)(de)位置、速度和(he)轉矩控(kong)(kong)制(zhi)，具(ju)有(you)高(gao)精(jing)度、高(gao)動(dong)(dong)態性能(neng)和(he)抗干(gan)擾能(neng)力(li)強的(de)(de)(de)特點。它通(tong)常用(yong)(yong)于需(xu)要精(jing)確(que)控(kong)(kong)制(zhi)運(yun)動(dong)(dong)和(he)動(dong)(dong)力(li)輸出(chu)的(de)(de)(de)場(chang)合，如(ru)數(shu)控(kong)(kong)機(ji)(ji)(ji)(ji)(ji)床、機(ji)(ji)(ji)(ji)(ji)器人、紡織機(ji)(ji)(ji)(ji)(ji)械等(deng)。而步(bu)(bu)進電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)是一種開環控(kong)(kong)制(zhi)系統，通(tong)過控(kong)(kong)制(zhi)脈沖個(ge)數(shu)來(lai)控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)轉動(dong)(dong)角度和(he)速度，具(ju)有(you)結構簡(jian)單、成本低、可靠性高(gao)的(de)(de)(de)特點。它通(tong)常用(yong)(yong)于需(xu)要實(shi)現(xian)簡(jian)單定位和(he)低速運(yun)動(dong)(dong)的(de)(de)(de)場(chang)合，如(ru)打印(yin)機(ji)(ji)(ji)(ji)(ji)、掃(sao)描(miao)儀(yi)、自動(dong)(dong)售貨機(ji)(ji)(ji)(ji)(ji)等(deng)。伺(si)服(fu)驅(qu)動(dong)(dong)器和(he)伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)匹(pi)配時，要檢查額定電(dian)(dian)(dian)(dian)流和(he)電(dian)(dian)(dian)(dian)壓。嘉興英威騰MH860伺(si)服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)(ji)(ji)抱閘

同服電(dian)機的(de)優點之一是(shi)精(jing)度(du)高。采用位(wei)置、速(su)度(du)和力矩的(de)閉環(huan)控制(zhi)技術(shu)，實(shi)現了對位(wei)置、速(su)度(du)和力矩的(de)準(zhun)確控制(zhi)。英威騰MH860伺服電(dian)機說明書(shu)

伺服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)選型(xing)的注意(yi)事項1、有些系(xi)(xi)統(tong)如(ru)傳送裝(zhuang)置(zhi)(zhi)，升降裝(zhuang)置(zhi)(zhi)等要求(qiu)伺服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)能(neng)盡快停車，而在故(gu)障、急停、電(dian)(dian)(dian)(dian)源斷電(dian)(dian)(dian)(dian)時伺服(fu)器(qi)(qi)(qi)(qi)沒有再生制(zhi)(zhi)動，無法對(dui)電(dian)(dian)(dian)(dian)機(ji)(ji)減(jian)速。同時系(xi)(xi)統(tong)的機(ji)(ji)械慣量又較大(da)(da)，這時對(dui)動態(tai)制(zhi)(zhi)動器(qi)(qi)(qi)(qi)的要依據負載(zai)的輕重、電(dian)(dian)(dian)(dian)機(ji)(ji)的工作速度等進(jin)行選擇。2、有些系(xi)(xi)統(tong)要維持機(ji)(ji)械裝(zhuang)置(zhi)(zhi)的靜(jing)止(zhi)位置(zhi)(zhi)，需(xu)電(dian)(dian)(dian)(dian)機(ji)(ji)提(ti)供較大(da)(da)的輸出轉(zhuan)矩，且停止(zhi)的時間較長(chang)。如(ru)果使用伺服(fu)的自鎖功(gong)能(neng)，往(wang)往(wang)會造成(cheng)電(dian)(dian)(dian)(dian)機(ji)(ji)過熱或放大(da)(da)器(qi)(qi)(qi)(qi)過載(zai)，這種情況就要選擇帶(dai)電(dian)(dian)(dian)(dian)磁(ci)制(zhi)(zhi)動的電(dian)(dian)(dian)(dian)機(ji)(ji)。3、有的伺服(fu)驅動器(qi)(qi)(qi)(qi)有內置(zhi)(zhi)的再生制(zhi)(zhi)動單元，但(dan)當再生制(zhi)(zhi)動較頻繁時，可(ke)能(neng)引起直流(liu)母線電(dian)(dian)(dian)(dian)壓過高(gao)，這時需(xu)另配再生制(zhi)(zhi)動電(dian)(dian)(dian)(dian)阻。再生制(zhi)(zhi)動電(dian)(dian)(dian)(dian)阻是否需(xu)要另配，配多(duo)大(da)(da)，可(ke)參照相應樣本的使用說明(ming)來配。4、如(ru)果選擇了(le)帶(dai)電(dian)(dian)(dian)(dian)磁(ci)制(zhi)(zhi)動器(qi)(qi)(qi)(qi)的伺服(fu)電(dian)(dian)(dian)(dian)機(ji)(ji)，電(dian)(dian)(dian)(dian)機(ji)(ji)的轉(zhuan)動慣量會增(zeng)大(da)(da)，計算轉(zhuan)矩時要進(jin)行考慮。
