In other case, the Z-phase width will be equal to the encoder resolution, andwill not synchronize with A-phase because of narrower width than that of A-phase.ABZsynchronizedABZnot-synchronizedPr0.11Pr5.03when the encoder resolution × ismultiple of 4,Pr0.11Pr5.03when the encoder resolution × isnot multiple of 4,• In case of the 5-wire, 20-bit incremental encoder, the signal sequence might not follow theabove fig. until the first Z-phase is fed out. When you use the pulse output as the controlsignal, rotate the motor one revolution or more to make sure that the Z-phase is fed out atleast once before using.
