1. Reads the position feedback.
2. Adds the origin to the feedback.
3. Determines modulo from Step 2 by the actual feedback bits.
4. Sets the position feedback sign according to FB1.INITSIGNED.
Example
This example uses set to 2 (degrees)
It also assumes that the drive is connected to a single turn feedback device with memory.
FB1.ORIGIN is set to 22 and saved into NV memory.
Drive boots and reads from feedback device position 340 degrees. According to the description section
above, calculation will be:
(340 + 22) modulo 360 = 2 degrees.
Therefore the initial feedback value will be set to 2 degrees.
