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(jìn)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(jìn)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(jìn)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(jìn)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(jìn)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(jìn)行放大。?

伺服機構(gòu)的步進(jìn)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(jìn)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(jìn)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(jìn)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(jìn)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(jìn)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(jìn)電機的轉(zhuǎn)角進(jìn)而控制伺服機構(gòu)的進(jìn)給量;同時通過編程控制脈沖頻率就是伺服機構(gòu)的進(jìn)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(jìn)電機的通電順序分配到相應(yīng)的繞組。

的步進(jìn)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(jìn)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)。
