Revolutions Position
Provided the set-up parameters are correct, the position is always converted to units of 1/2
be relevant depending on the resolution of the feedback device. For example if 10 bit resolution is selected the resolver produces 4,096 counts per
revolution, and so the position is represented by the bits in the shaded area only.

Revolutions Position
When the feedback device rotates by more than one revolution, the revolutions in Pr x. 04 increment or decrement in the form of a sixteen bit roll-over
counter.
