My motor does not start in closed loop control ERROR_INDEX_NOT_FOUND_YET = 0x20

Hello,

I am currently testing 2 small motors from an FPV drone (2300KV and 260KV) in combination with the AMT102 Encoder. Unfortunately I have no reaction from this engine after i start closed loop control

  • Motor calibration works finde
  • Encoder calibration works fine if index was found
  • index search works fine most time

But if i type in AXIS_STATE_CLOSED_LOOP_CONTROL axis0 says ERROR_INDEX_NOT_FOUND_YET = 0x20

But before index searching worked well…

Here you can see the two motors i used for testing, same problem with both.
I also checked Encoder shadow_count and i can see the values.

I solved it, but don`t know how exactly. Maybe my pole pair setting was wrong.
