TMS320F280049C: TMS320F280049C

Part Number: TMS320F280049C
Other Parts Discussed in Thread: C2000WARE, , DRV8323, MOTORWARE

Tool/software:

Hello,
I am using the TMS320F280049C in conjunction with the CCS v12. My project is based on the is10 project from C2000Ware_MotorControl_SDK_5_02_00_00.
The hardware is an in-house development based on the eval board of the TMS320F280049C and the DRV8323 board. I use this setup to control a BLDC motor, and now I would like to recalibrate a Rs. To do this, I set the flagEnableRsRecalc - unfortunately without success. What would be the correct procedure to recalibrate? I don't want to do an online calibration, the motor shouldn't turn.

Is there any documentation besides the “2000Ware MotorControl SDK in TI Resource Explorer.html” such as the spruhj1i.pdf for the older motorware_1_01_00_18?
e.g. I can't find any documentation on EST_getIdRated_A; what kind of signal is it, where is it measured, are there any block diagrams that show something like this?
Has the Estimator implemented its own trajectories for Id?


are there any besides the
Many greetings

    Hello 

    It looks to me as if the estimator has implemented its own trajectory generators – do these already run when the function “EST_enable(estHandle)” and “EST_enableTraj(estHandle)” are called?


    It seems as if there are separate trajectory generators for Id and Iq – how are these activated – is there an enable/run function?

    Is there any documentation/overview diagrams showing the Estimator blocks and their interrelationships, as well as the signal names connected to the blocks?

    Kind regards,
    Thomas Hecht
