Other Parts Discussed in Thread: BOOSTXL-DRV8301, MOTORWARE

I have a

motor : BLDC motor

motor drive : BOOSTXL-DRV8301

I want to run my bldc motor in torque mode. so I had operated motor with using lab5a example of motorware.

When gMotorVars.IqRef_A is set to 0.5, motor is rotated. it's ok . (reverse rotating also is ok-gMotorVars.IqRef_A=-0.5)

but when motor is rotating and gMotorVars.IqRef_A is set to 0, motor is not stopped.

and when load is applied at axis of motor, motor is stopped.

I don't know why?

thank you so much.
