1.用一个直流电源给电机的UV绕组通以小于额定电流的直流电,U入,V出,将电机轴定向至一个平衡位置;
N4H348AKF200.用示波器观察编码器的U相信号和Z信号;
3.调整编码器转轴与电机轴的相对位置;
4.一边调整,一边观察编码器U相信号跳变沿,和Z信号,直到Z信号稳定在高电平上(在此默认Z信号的常态为低电平),锁定编码器与电机的相对位置关系;
5.来回扭转电机轴,撒手后,若电机轴每次自由回复到平衡位置时,Z信号都能稳定在高电平上,则对齐有效。
撤掉直流电源后,验证如下:
1.用示波器观察编码器的U相信号和电机的UV线反电势波形;
N4H348AKF200.转动电机轴,编码器的U相信号上升沿与电机的UV线反电势波形由低到高的过零点重合,编码器的Z信号也出现在这个过零点上。
