目前，主流的伺服驅(qū)動器均采用數(shù)字信號處理器）作為控制核心，可以實現(xiàn)比較復(fù)雜的控制算法，實現(xiàn)數(shù)字化、網(wǎng)絡(luò)化和智能化。功率器件普遍采用以智能功率模塊（IPM）為核心設(shè)計的驅(qū)，IPM內(nèi)部集成了驅(qū)動電路，同時具有過電壓、過過熱、欠壓等故障檢，在主回路中還加入軟啟動電路，以減小啟動過程對驅(qū)動器的沖擊。

功率驅(qū)動單元首先通過三相全橋整流電路對輸入的或者市電進行整流，得到相應(yīng)的直流電。經(jīng)過整流好的三相電或市電，再通過三相正弦PWM電壓變頻來驅(qū)動三相永磁式同步交流伺服電機。功率驅(qū)動單元的整個過程可以簡單的說就是AC-DC-AC的過程。整流單元（AC-DC）主要的拓?fù)潆娐肥侨嗳珮虿豢卣麟娐贰?/p>

隨著伺服系統(tǒng)的大規(guī)模應(yīng)用，伺服驅(qū)動器使用、伺服驅(qū)動器調(diào)試、伺服驅(qū)動器維修都是伺服驅(qū)動器在當(dāng)今比較重要的技術(shù)課題，越來越多工控技術(shù)服務(wù)商對伺服驅(qū)動器進行了技術(shù)深層次研究。

伺服驅(qū)動器是現(xiàn)代運動控制的重要組成部分，被廣泛應(yīng)用于工業(yè)機器人及數(shù)控加工中心等自動化設(shè)備中。尤其是應(yīng)用于控制交流永磁同步電機的伺服驅(qū)動器已經(jīng)成為國內(nèi)外研究熱點。當(dāng)前交流伺服驅(qū)動器設(shè)計中普遍采用基于矢量控制的電流、速度、位置3閉環(huán)控制算法。該算法中速度閉環(huán)設(shè)計合理與否，對于整個伺服控制系統(tǒng)，特別是速度控制性能的發(fā)揮起到關(guān)鍵作用。

配的伺服電機的驅(qū)動器工作原理是怎么樣的？

伺服驅(qū)動器（servo drives）又稱為“伺服控制器"、“伺"，是用來控制伺服電機的一種控制器，其作用類似于作用于普通交，屬于伺服系統(tǒng)的一部分，主要應(yīng)用于高精度的定位系統(tǒng)。一般是通過位置、速度和力矩三種方式對伺服馬達(dá)進行控制，實現(xiàn)高精度的傳動系統(tǒng)定位，目前是傳動技術(shù)的產(chǎn)品。

 隨著全數(shù)字式交流伺服系統(tǒng)的出現(xiàn)，交流伺服電機也越來越多地應(yīng)用于數(shù)字控制系統(tǒng)中。為了適應(yīng)數(shù)字控制的發(fā)展趨勢，運動控制系統(tǒng)中大多采用全數(shù)字式交流伺服電機作為執(zhí)行電動機。在控制方式上用脈沖串和方向信號實現(xiàn)。?

一般伺服都有三種控制方式：速度控制方式，轉(zhuǎn)矩控制方式，位置控制方式

伺服驅(qū)動器的工作原理

首先功率驅(qū)動單元通過三相全橋整流電路對輸入的三相電或者市電進行整流，得到相應(yīng)的直流電。經(jīng)過整流好的三相電或市電，再通過三相正弦PWM電壓型逆變器變頻來驅(qū)動交流伺服電機。功率驅(qū)動單元的整個過程可以簡單的說就是AC-DC-AC的過程，整流單元（AC-DC）主要的拓?fù)潆娐肥侨嗳珮虿豢卣麟娐贰?/p>

般PLC的輸出具有一定的驅(qū)動能力，而通常的直流輸出接口的負(fù)載能力僅為十幾—幾十伏特、幾十—幾百毫安;但對于功率步進電機則要求幾十—上百伏特、幾安—十幾安的驅(qū)動能力，因此應(yīng)該采用驅(qū)動器對輸出脈沖進行放大。?

伺服機構(gòu)的步進電機無脈沖輸入時便停止運轉(zhuǎn)，伺服執(zhí)行機構(gòu)定位。當(dāng)伺服執(zhí)行機構(gòu)的位移速度要求較高時，可以用PLC中的高速脈沖發(fā)生器。不同的PLC其高速脈沖的頻率可達(dá)4000—6000Hz。對于自動線上的一般伺服機構(gòu)，其速度可以得到充分滿足。

如伺服機構(gòu)采用硬件環(huán)行分配器，則占用PLC的I/O口點數(shù)少于5點，一般僅為3點。其中I口占用一點，作為啟動控制信號;O口占用2點，一點作為PLC的脈沖輸出接口，接至伺服系統(tǒng)硬環(huán)的脈沖輸入端，另一點作為山社步進電機轉(zhuǎn)向控制信號，接至硬環(huán)的相序分配控制端。

伺服系統(tǒng)采用軟件環(huán)行分配器時，將PLC控制的開環(huán)伺服機構(gòu)用于某大型生產(chǎn)線的數(shù)控滑臺，每個滑臺僅占用4個I/O接口，節(jié)省了控制系統(tǒng)，其脈沖當(dāng)量為0.01~0.05mm，進給速度為Vf=3~15m/n，*工藝要求和加工精度要求

步與伺服電機驅(qū)動器的區(qū)別在于：

1.轉(zhuǎn)速要求不同：步進適合低轉(zhuǎn)速場合，轉(zhuǎn)速調(diào)整范圍較小的場合。伺服電機可控轉(zhuǎn)速較大的場合。

2.可控可靠性不同：因為伺服電機有反饋信號，因此在控制系統(tǒng)里里，可以實現(xiàn)高可靠性控制。

3.輸出轉(zhuǎn)矩要求不同：目前國外和國內(nèi)，步進電機最大系列為130框。最大輸出靜轉(zhuǎn)矩為50牛/米。伺服電機可以有180框以上，60牛/米以上的輸出轉(zhuǎn)矩可選。

的控制系統(tǒng)由可編程控制器、環(huán)行脈沖分配器和步進電機功率驅(qū)動器組成，控制系統(tǒng)中用來產(chǎn)生控制脈沖;通過plc編程輸出一定數(shù)量的方波脈沖，控制山社步進電機的轉(zhuǎn)角進而控制伺服機構(gòu)的進給量;同時通過編程控制脈沖頻率就是伺服機構(gòu)的進給速度，環(huán)行脈沖分配器將可編程控制器輸出的控制脈沖按步進電機的通電順序分配到相應(yīng)的繞組。

的步進電機可以采用軟件環(huán)行分配器，也可以采用硬件環(huán)行分配器。采用軟環(huán)占用的PLC資源較多，特別是步進電機繞組相數(shù)M》4時，對于大型生產(chǎn)線應(yīng)該予以充分考慮。采用硬件環(huán)行分配器，雖然硬件結(jié)構(gòu)稍微復(fù)雜些，但可以節(jié)省占用PLC的點數(shù)。
