CCS/TMS320F28026F: Automotive 48V 1kW Motor Drive Reference Design TIDA-00281

Part Number: TMS320F28026F
Other Parts Discussed in Thread: TIDA-00281

Tool/software: Code Composer Studio

I'm working on BLDC motor controllers.I saw TIDA-00281 48V BLDC referance desing.I want to work on it but I couldn't understand how can we setting its speed or its forward and reverse settings.

I couldn't see any potensiometer or something like that and any button for its forward and reverse settings.Is that all software settings. If I want to add a potensiometer and a button is that possible and if its possible how can I do that.


Thank you,

Best regards.

  • On page 40 of the TIDA-00281 reference guide, it explains how to change the motor speed:

    Step 10: To change the commanded speed, click on the value field of SpeedRef_krpm and enter a new value (in kRPM).

    To change the acceleration, click on the value field of MaxAccel_krpmps and enter a new value (in kRPM per second).

    Note that the speed reference can be either positive or negative, affecting whether the motor rotation is clockwise or



    If you want to add a potentiometer, you would need to add also software to read the value of the potentiometer (into TMS320's ADC) and use that for a speed command.  This is beyond the scope of the TIDA-00281 reference design.
