1.用一個(gè)直流電源給電機(jī)的UV繞組通以小于額定電流的直流電，U入，V出，將電機(jī)軸定向至一個(gè)平衡位置；
N4H348AKF200.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(lái)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。
撤掉直流電源后，驗(yàn)證如下：
1.用示波器觀察編碼器的U相信號(hào)和電機(jī)的UV線反電勢(shì)波形；
N4H348AKF200.轉(zhuǎn)動(dòng)電機(jī)軸，編碼器的U相信號(hào)上升沿與電機(jī)的UV線反電勢(shì)波形由低到高的過(guò)零點(diǎn)重合，編碼器的Z信號(hào)也出現(xiàn)在這個(gè)過(guò)零點(diǎn)上。
