　　該數(shù)控分度頭在徑向安裝數(shù)顯尺來(lái)控制徑向分度尺寸；由plc控制步進(jìn)電機(jī)軸向分度。操作人員啟動(dòng)電源，輸入分度數(shù)后，調(diào)整/分度開(kāi)關(guān)置于分度位置即可實(shí)現(xiàn)手動(dòng)或自動(dòng)分度。在自動(dòng)分度中可實(shí)現(xiàn)分度機(jī)構(gòu)的松開(kāi)、上升、分度、下降、卡緊再松開(kāi)的順序控制。

分度算法

　　設(shè)總孔數(shù)為d2，總脈沖數(shù)d0，分度脈沖可計(jì)算為：d0/d2=d4+d5（余數(shù)）。若d5=0時(shí)，步進(jìn)電機(jī)每轉(zhuǎn)動(dòng)一次，電機(jī)轉(zhuǎn)角控制脈沖均為d4。若d5≠0時(shí)，將d5與孔數(shù)的一半（d2/2=d8）進(jìn)行比較，若小于孔數(shù)的一半，步進(jìn)電機(jī)先按d4個(gè)脈沖分度，步進(jìn)電機(jī)每轉(zhuǎn)過(guò)一個(gè)分度角，余數(shù)d5累積一次，當(dāng)累積數(shù)大于d8時(shí)，步進(jìn)電機(jī)則按d4+1個(gè)脈沖分度一次，此時(shí)累積數(shù)減去d4+1脈沖的余數(shù)即d2-d5，然后再按d4個(gè)脈沖分度，依次類推直至分度完畢；若余數(shù)大于孔數(shù)的一半，步進(jìn)電機(jī)先按d4+1個(gè)脈沖分度，余數(shù)按d2-d5累積，當(dāng)累積數(shù)大于d8時(shí)，步進(jìn)電機(jī)則按d4個(gè)脈沖分度一次，此時(shí)累積數(shù)減去d4脈沖的余數(shù)d5，然后再按d4+1個(gè)脈沖分度，依次類推直至分度完畢。這樣的分度算法，使孔與孔之間的分度誤差始終小于一個(gè)脈沖當(dāng)量，可以實(shí)現(xiàn)在3600轉(zhuǎn)角誤差為0的分度精度要求。

變頻電動(dòng)機(jī)的特點(diǎn) 

　　1、電磁設(shè)計(jì) 
　　對(duì)普通異步電動(dòng)機(jī)來(lái)說(shuō)，再設(shè)計(jì)時(shí)主要考慮的性能參數(shù)是過(guò)載能力、啟動(dòng)性能、效率和功率因數(shù)。而變頻電動(dòng)機(jī)，由于臨界轉(zhuǎn)差率反比于電源頻率，可以在臨界轉(zhuǎn)差率接近1時(shí)直接啟動(dòng)，因此，過(guò)載能力和啟動(dòng)性能不在需要過(guò)多考慮，而要解決的關(guān)鍵問(wèn)題是如何改善電動(dòng)機(jī)對(duì)非正弦波電源的適應(yīng)能力。方式一般如下： 

　　1） 盡可能的減小定子和轉(zhuǎn)子電阻。 
　　減小定子電阻即可降低基波銅耗，以彌補(bǔ)高次諧波引起的銅耗增 

　　2）為抑制電流中的高次諧波，需適當(dāng)增加電動(dòng)機(jī)的電感。但轉(zhuǎn)子槽漏抗較大其集膚效應(yīng)也大，高次諧波銅耗也增大。因此，電動(dòng)機(jī)漏抗的大小要兼顧到整個(gè)調(diào)速范圍內(nèi)阻抗匹配的合理性。 

　　3）變頻電動(dòng)機(jī)的主磁路一般設(shè)計(jì)成不飽和狀態(tài)，一是考慮高次諧波會(huì)加深磁路飽和，二是考慮在低頻時(shí)，為了提高輸出轉(zhuǎn)矩而適當(dāng)提高變頻器的輸出電壓。
