HONEYWELL Q270A1024需要注意的是，此時增量式編碼器的U相信號的相位零點與電機UV線反電勢的相位零點對齊，由于電機的U相反電勢，與UV線反電勢之間相差30度，因而這樣對齊后，增量式編碼器的U相信號的相位零點與電機U相反電勢的-30度相位點對齊，而電機電角度相位與U相反電勢波形的相位一致，所以此時增量式編碼器的U相信號的相位零點與電機電角度相位的-30度點對齊。 

有些伺服企業(yè)習慣于將編碼器的U相信號零點與電機電角度的零點直接對齊，為達到此目的，可以：
 
1.用一個直流電源給電機的UVW繞組通以小于額定電流的直流電，VW入，U出，將電機軸定向至一個平衡位置； 
2.用示波器觀察編碼器的U相信號和Z信號； 
3.調(diào)整編碼器轉(zhuǎn)軸與電機軸的相對位置； 
4.一邊調(diào)整，一邊觀察編碼器U相信號跳變沿，和Z信號，直到Z信號穩(wěn)定在高電平上（在此默認Z信號的常態(tài)為低電平），鎖定編碼器與電機的相對位置關(guān)系； 
5.來回扭轉(zhuǎn)電機軸，撒手后，若電機軸每次自由回復到平衡位置時，Z信號都能穩(wěn)定在高電平上，則對齊有效。 用伺服驅(qū)動器讀取編碼器的單圈位置值，并存入編碼器內(nèi)部記錄電機電角度初始相位的EEPROM中； 
4.對齊過程結(jié)束。
