AKD PDMM User Guide | 31.12 FB1.ORIGIN
FB1.OFFSET is a value added to the position feedback (PL.FB (pg 403)).
Example
If PL.FB is 10 deg and FB1.OFFSET is set to –10 deg, then the next read of PL.FB will return
~0 deg.

Description
FB1.ORIGIN is a value that is added to the feedback device position. Initial value and modulo
are determined from the number of bits of the feedback:
Initial position value = ( <feedback from device> + FB1.ORIGIN ) modulo <number of feedback
bits>
The number of feedback bits is set according to the feedback type. For memory feedbacks it is
the number of feedback bits; for none memory it is always single turn.
The drive internal process for the feedback initialization is as follows:
