(1)增量型：就是每转过单位的角度就发出一个脉冲信号(也有发正余弦信号，然后对其进行细分，斩波出频率更高的脉冲)，通常为A相、B相、Z相输出，A相、B相为相互延迟1/4周期的脉冲输出，根据延迟关系可以区别正反转，而且通过取A相、B相的上升和下降沿可以进行2或4倍频;Z相为单圈脉冲，即每圈发出一个脉冲。

(2)绝对值型：就是对应一圈，每个基准的角度发出一个唯一与该角度对应二进制的数值，通过外部记圈器件可以进行多个位置的记录和测量。

(1) Incremental type: That is, each time the Angle of the unit is sent out A pulse signal (there is also A sine and cosine signal, and then it is subdivided, and the pulse with higher frequency is chopped), usually for phase A, phase B, phase Z output, phase A, phase B is the pulse output with a mutual delay of 1/4 cycle, and the positive and negative rotation can be distinguished according to the delay relationship. And by taking the rising and falling edges of phase A and phase B, the frequency can be doubled by 2 or 4. The Z phase is a single-turn pulse, that is, one pulse is emitted per turn.

(2) Absolute value type: It is corresponding to a circle, each reference Angle sends a unique binary value corresponding to the Angle, and multiple positions can be recorded and measured through the external loop device.
