Part Number: TMS320F28034
Other Parts Discussed in Thread: CONTROLSUITE, C2000WARE-MOTORCONTROL-SDK, C2000WARE

Hi team,

Here's an issue from the customer may need your help:

During the debug of routine, when the motor is in forward rotation, the estimated angle is correct while when the motor is in reverse rotation, it will get an incorrect estimated angle.

The customer would like to know how to configure to make the smo reverse rotation estimation correctly? Could you help check this case? Thanks.

Best Regards,

Cherry

    This example in controlSUITE is just support unidirectional rotation. You may refer to the update eSMO example in MotorControlSDK.

    You may download and install the latest MotorControlSDK,  which can support a set of hardware kits and control algorithms for BLDC/PMSM drive. The kits include LAUNCHXL-F280025C with BOOSTXL-DRV8323RS, or BOOSTXL-DRV8323RH, or DRV8353Rx-EVM, or BOOSTXL-3PHGANINV, or DRV8316REVM. The control algorithms include InstaSPIN or eSMO based Sensorless-FOC, and incremental encoder or hall sensor based sensored-FOC.  The detailed introduction about the lab can be found in the lab user’s guide as the links below.

    On this forum, we encourage the users/customers to post their questions directly if possible.  

    “Thanks for your questions on the solutions in controlSUITE.  I’d like to point out that these solutions in controlSUITE are about 10 years old and haven’t had any updates in that time. We recommend our customers use our latest generation of devices which are supported for InstaSPIN-FOC, other sensorless techniques, and sensored servo control through C2000Ware-MotorControl-SDK”
