PMSM FOC Build level 2 is not working

Which kit are you referring to?

there are no controlSUITE sensored FOC projects for the DRV83x kits. Are you using the project for the HVKIT?

Post the exact path of the project you are using.

Hi,

Yes, there is no project for drv 83x kit. I'm using a modified version of 

C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.0\HVPM_Sensored. I've modified it for the drv 8332 motor controller.

I would suggest reviewing the modifications, especially in the pin-mapping, ADC channels, and scaling variables.

As you increase the speed reference, you should increase the voltage reference also. Try increasing VqTesting.

Hi,

I've tried to implement your suggestion. But I couldn't see any result. The problem is motor is not running smoothly.

PFA my pwm code. f2803xpwm.h

Make sure that in build level 1, you see sinusoidal voltage output from the inverter across line to line. You can put an RC filter at the inverter outputs to GND, and then probe any two outputs of inverter using a scope and use its MATH feature to find the difference between these two signals. if you get a sinusoid, then the PWM logic is ok.

The problem you mention seem to be a symptom of inappropriate Voltage and Frequency. If you see the motor spinning at low speed commands, it means that the voltage setting seem to tally with the speed setting.

Probably, if you spend some more time digging through the issue, you may find the answer.
