LAUNCHXL-F280049C: instaspin, LAB_06_torque control , negative Iq_ref

Hi,

I trying to use insaspin to control motor.

DEVICE : LAUNCHXL-280049C + BOOSTXL-DRV8320RS

I followed the procedure in th lab_06.

And I feel the torque of motor by changing IdqSet_A[1] which means Iq_ref.

But, when negative value is assigned to IdqSet_A[1], the motor doesn't work well.

What should I do for negative torque?

Thank you
