TMS320F280025: Request for Guidance on Implementing V/F Control in TIDM-02010 DMPFC Code

Other Parts Discussed in Thread: C2000WARE

Tool/software:

Dear TI Support Team,

We are currently working with the C2000Ware MotorControl SDK 5.04.00.00, using the reference solution:

C:\ti\c2000\C2000Ware_MotorControl_SDK_5_04_00_00\solutions\tidm_02010_dmpfc\f28002x

Our objective is to drive a compressor motor in V/F mode. We have modified the drive code accordingly; however, the generated PWM pulses remain constant. For proper V/F control, we require sinusoidally modulated PWM pulses (varying duty cycle with frequency), but at present, only constant pulses are being generated.

Could you please advise what modifications are required in this reference code to achieve sinusoidal PWM output suitable for V/F motor drive?

Your guidance on the necessary changes will be highly appreciated.

Best regards,
Navaneeth Kumar
