CCS: Performance test of boostxl-3phganinv inverter

Tool/software: Code Composer Studio

Recently, I started this inverter board and wanted to combine it with 28379d to complete the inverter. There is a routine of two motors for this inverter board and 28379d, but I don't have any related motors on hand. Can I test it by connecting the output terminals VA, VB and VC with three-phase load? Or write SPWM or SVPWM algorithm on 28379d, and then connect 28379d with inverter board for testing. Can the sine wave after inversion be tested on oscilloscope? I'm a novice. I hope I can be instructed. thank!

You can run the LEVEL 1 in the example code in motorControlSDK that is open-loop control without connecting the motor to check the PWM and voltage output as you want. Maybe, LEVEL 2 should be also ok for this.

Thank you for your answer. I understand. But when I test the dual motor routine, I completely follow the file "spraco 3" in all the steps. Because the R20 on the inverter board is not removed, I cannot get the waveform in CCS. How to remove R20 (a resistor?) from the inverter board?Looking forward to your help.

You can find the related hardware document and schematic of the kit as the links below, and refer to the schematic to remove the R20 by soldering.
