TMS320F280049C: Servo_Drive_with_CAN project motor spin in opposite direction in closed loop

Part Number: TMS320F280049C
Other Parts Discussed in Thread: DRV8320

Hi Expert,

I run the Servo_Drive_with_CAN project with C280049 and DRV8320.

When I spin the motor in open loop, with positive speed command, the motor direction is correct.

But in closed loop, the motor spins in opposite direction. I think it may caused by the encoder angle offset, how do we compensate the encoder angle offset in this software?

    For this lab it is important to ensure that the physical connections are done correctly. If the motor or encoder wires are connected in the wrong order, the lab will not function properly. please check the encoder and motor lines connection order. This lab has include offset calibration for the encoder.
