AKD PDMM User Guide | 31.13 FB1.P
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.

General Information
Type R/O Parameter
Description Reads position from the primary feedback.
Units Depends on FB1.UNIT counts or custom units.
Range N/A
Default
Value
N/A
Data Type S64
Start Version M_01-05-08-000
Description
This parameter reads the position of the primary feedback device connected to X10. The posi-
tion can be read as counts or in customer units. This is the raw position read back from the
device. The output format is 32:32, the upper 32 bits represent the multi-turns and the lower 32
bits represent the position of the feedback.
