DESCRIPTION: modular incremental encoder
•Square-wave accuracy:
•Pitch error of period:
•Pitch error of phase position:
•Z phase:
•Period of pulses:
•Signal accuracy:
X₁ +X₂ = 1/2T ± 1/12T
X₃ +X₄ = 1/2T ± 1/12T
±0.01T
≤ 1/18T
Tz=1/4T (1T, 1/2T, 1/4T...)
T=360° /N (N: output pulses)
Xn=1/4T ± 1/12T (n=1, 2, 3, 4)
A leads B clockwise when viewing the encoder shaft end.
The position of Z phase against A, B phase is not specified.
