Unexpected movement under CONTROL_MODE_TORQUE_CONTROL & input_torque=0

When under CONTROL_MODE_TORQUE_CONTROL and input_torque =0 I get electrical power >0
It naturally creates a CW movement, if I set torque to -0.3Nm it balances out and stops spinning.
How can this be? shouldn’t input_torque=0 be as good as IDLE?
ODrive 3.6, 48v bus, industrial servo Mige 130st-10010. 4 phase pairs, 9A max, 2.2Nm/A

it was build 0.5.5, downgrade to 0.5.4 and erase_config made it go away, carry on.

Curious. That shouldn’t have affected anything. Maybe just update to 0.5.5 then erase_configuration?

Yes, I think you are right. I neglected to erase config after initial upgrade to 5.5. I’ll stick to 5.4 for now, at least until my build is stable.
