Zero pulses which can be evaluated
are only available for rotary encoders

Fig. 6-68 Angular incremental encoder signals for absolute value encoders with sin/cos 1Vpp and EnDat
interface
Note
If the absolute value encoder has more than 2
n
=2048 increments
(n=11), then one zero mark is output for each 2048 increments.
This means, that encoder pulse number/2048 zero marks are output at
the angular incremental encoder interface per motor revolution;
whereby the factor angular incremental encoder pulse number/encoder
pulse number is selected as 1:1.
