Encoder work principle

- May 08, 2020-

Encoder per revolution,the A and B will send same number of pulse,but the A and B has 90° Electrical angular phase difference,you can according to the phase difference to judge the encoder is corotation or reverse;when it corotation,A phase will ahead of B phase to phase input,reverse it.the B phase will ahead of A phase to input.so the encoder per revolution,Z phase will send the one pulse on the fixed position,It can be used as reset phase or zero phase
