Kuna the difference between phase A and phase B is 90 degrees, the forward and reverse rotation of the encoder can be determined by comparing kas phase A is in front or phase B is in front, and the zero reference bit of the encoder can be geted through the zero pulse.

Resolutsioon-The encoder is called resolution by how many through or dark lines are provided per rotation of 360 degrees, also known as analytical indexing, or directly weighting how many lines, general in 5~10000 lines per revolution.
