If motor fails to spin in open loop continuously or if motor current oscillates without spinning the motor, the user can fine tune the open loop configurations in the RAM ALGO DEBUG 2 parameters.
To verify the signal path or check the motor parameters accuracy, the user can disable the current loop by setting the currLoopDis bit and setting the forceVQCurrLoopDis and forceVDCurrLoopDis on the Register Map page.
Adjust Vd and Vq values to spin the motor. Once the motor is spinning at a constant speed, observe the Id and Iq outputs in the User Outputs section of the Motor Tuning page to check the stability of the current loop.
