Part Number: TIDA-00366
Other Parts Discussed in Thread: AMC1311, AMC1301, UCC21530, MOTORWARE, CONTROLSUITE

Tool/software: Code Composer Studio

I like TIDA-0036 very much, I am developing inveter in inducting motor control, I have done HW like this, where I get the test code?

    Hello,

    Thank you for your interest in TIDA-00366. The TI reference design TIDA-00366 was build to demonstrate the performance of our reinforced isolated gate drivers UCC21530 and reinforced isolated amplifiers AMC1301/AMC1311. Unfortunately we won't have specific C2000 firmware for that hardware platform.  

    For C2000 software you may use the latest C2000 motor control SDK which has example code for motor control applications: http://www.ti.com/tool/C2000WARE-MOTORCONTROL-SDK. This SDK does not support the F28027F derivative. When you like to use the F28027F LaunchPad, you may use the C2000 MotorWare:
    http://www.ti.com/tool/MOTORWARE or controlSUITE: http://www.ti.com/tool/CONTROLSUITE

    For the above software packages, you will need to slightly adapt the corresponding example code to the TIDA-00366 hardware, like PWM and ADC configuration.

    Hello, Martin Staebler

    I really appreciate your reply,  EST_RUN needs seven signals, Ia,Ib, Ic,Va,Vb ,Vc and Vbus, but in TIDA-00366 design we only have four signals Ia,Ib, Ic and Vbus, I notice you picture of controlling motor using TIDA-00366, I am confused by this. How do I process signal Va,Vb ,Vc. In many example project define "HAL_AdcData_t gAdcData = {0,0,0,0,0,0,0}; "    // Contains Current and Voltage ADC readings in global Q format. Your advice will be great help to me , thank you very much.

    Hello,

    if you plan to use the FAST observer as part InstaSPIN-FOC, you will need a hardware which feeds back the three phase voltages as described in the MotorWare documentation.

    The TIDA-00366 hardware won't have the phase voltage feedback.

    If you like to run your motor (ACIM or PMSM) sensorless with InstaSPIN-FOC and the FAST observer, you need to have a compliant hardware. I'd see two options:


    a) You may either order the high High Voltage Motor Control Kit with InstaSPIN-FOC and InstaSPIN-MOTION enabled Piccolo MCU http://www.ti.com/tool/TMDSHVMTRINSPIN. You will need to judge if this kits meets you AC input and motor voltage and current and of course isolation ratings.

    b) If TIDA-00366 meets your voltage, power and current and isolation needs, or you may modify the TIDA-00366 to add the phase voltage feedback. Please pay caution when adding the voltage feedback. This requires not only to add a passive voltage divider and RC filter as shown with the InstaSPIN-FOC documentation, but also reinforced isolation towards the C2000 MCU. Since the TIDA-00366 is reinforced isolated towards the C2000 you need to add an isolated amplifier like the AMC1311 for each phase voltage node feedback including a 5V isolated bias supply for the AMC1311. Since the phase voltage is referenced to DC-, like the DC-link voltage, you can refer to the DC-link voltage feedback with AMC1311 on TIDA-00366 as an example. Of course add a capacitor to filter to the resistor feedback network to remove the PWM carrier frequency. You may either design an adapter PCB with blue wires (not ideal, I'd expect more noise) or add these change to the TIDA-00366 Altium project and build a new board. 

    Regards,
    Martin
