I have configured all things properly according to the datasheet, and the hardware connection is also correct, but still i am getting an error of NO Response. I also attached the datasheet of motor and encoder.

Anyone have a solution?
Hi! What encoder are you using?
Where did you buy the AMT212? From our shop, or from an external vendor like Digikey?
Hi was there any resolution to this? I am getting the same issue and I got my encoder from the Odrive shop
Hi! I believe we resolved this in DMs.
Can you show the configuration in the GUI (final tab in the configuration flow → copy the “python commands (advanced users)” ?
Also, in the inspector tab, what is rs485_encoder_group0.raw and rs485_encoder_group0.status?

Now when I tried again, I get procedure result as pole pair mismatch. So not sure what is happening. The motor moves in one direction during calibration and then stops.
