HONEYWELL Q270A1024需要注意的是，此時(shí)增量式編碼器的U相信號(hào)的相位零點(diǎn)與電機(jī)UV線反電勢(shì)的相位零點(diǎn)對(duì)齊，由于電機(jī)的U相反電勢(shì)，與UV線反電勢(shì)之間相差30度，因而這樣對(duì)齊后，增量式編碼器的U相信號(hào)的相位零點(diǎn)與電機(jī)U相反電勢(shì)的-30度相位點(diǎn)對(duì)齊，而電機(jī)電角度相位與U相反電勢(shì)波形的相位一致，所以此時(shí)增量式編碼器的U相信號(hào)的相位零點(diǎn)與電機(jī)電角度相位的-30度點(diǎn)對(duì)齊。 

有些伺服企業(yè)習(xí)慣于將編碼器的U相信號(hào)零點(diǎn)與電機(jī)電角度的零點(diǎn)直接對(duì)齊，為達(dá)到此目的，可以：
 
1.用一個(gè)直流電源給電機(jī)的UVW繞組通以小于額定電流的直流電，VW入，U出，將電機(jī)軸定向至一個(gè)平衡位置； 
2.用示波器觀察編碼器的U相信號(hào)和Z信號(hào)； 
3.調(diào)整編碼器轉(zhuǎn)軸與電機(jī)軸的相對(duì)位置； 
4.一邊調(diào)整，一邊觀察編碼器U相信號(hào)跳變沿，和Z信號(hào)，直到Z信號(hào)穩(wěn)定在高電平上（在此默認(rèn)Z信號(hào)的常態(tài)為低電平），鎖定編碼器與電機(jī)的相對(duì)位置關(guān)系； 
5.來回扭轉(zhuǎn)電機(jī)軸，撒手后，若電機(jī)軸每次自由回復(fù)到平衡位置時(shí)，Z信號(hào)都能穩(wěn)定在高電平上，則對(duì)齊有效。 用伺服驅(qū)動(dòng)器讀取編碼器的單圈位置值，并存入編碼器內(nèi)部記錄電機(jī)電角度初始相位的EEPROM中； 
4.對(duì)齊過程結(jié)束。
