DRV8312-69M-KIT: Running lab01b, the motor does not rotate

Part Number: DRV8312-69M-KIT

Dear team:

Background: lab01b (InstaSPIN Projects and Labs User’s Guide)

I have changed the program according to the document requirements. After load the project, The LD2 can blink, But the motor did not rotate and I can't measure any waveform (Only DC waveform) at J6-DAC1, DAC2, DAC3 or MOTOR-MOA, MOB, MOC on the broad.

Questions:

1, Can I directly measure the waveform in the figure below on the DRV8312EVM? If so, which terminal should I test?

2, In stap 2a, I need to set the right offset and gain for each PWMDAC channel in proj_lab01b.c and hal.c as below:

// set DAC parameters
 gDacData.ptrData[0] = &gPwmData.Tabc.value[0];
 gDacData.ptrData[1] = &gPwmData.Tabc.value[1];
 gDacData.ptrData[2] = &gPwmData.Tabc.value[2];
 gDacData.ptrData[3] = &gAdcData.V.value[0];
 HAL_setDacParameters(halHandle, &gDacData);

But in lab01b, do the other lines of parameters in the same location need to be commented out?

// set DAC parameters

  gDacData.ptrData[0] = &gPwmData.Tabc.value[0];
  gDacData.ptrData[1] = &gPwmData.Tabc.value[1];
  gDacData.ptrData[2] = &gPwmData.Tabc.value[2];
  gDacData.ptrData[3] = &gAdcData.V.value[0];

//  gDacData.ptrData[0] = &angle_gen.Angle_pu;
//  gDacData.ptrData[1] = &gAdcData.I.value[0];
//  gDacData.ptrData[2] = &gPwmData.Tabc.value[0];
//  gDacData.ptrData[3] = &gAdcData.V.value[0];

  HAL_setDacParameters(halHandle, &gDacData);

The same problem can be found in Step 2b, set the right offset and gain for each PWMDAC channel in proj_lab01b.c and hal.c：

// set DAC parameters
 gDacData.ptrData[0] = &angle_gen.Angle_pu;
 gDacData.ptrData[1] = &gAdcData.I.value[0];
 gDacData.ptrData[2] = &gPwmData.Tabc.value[0];
 gDacData.ptrData[3] = &gAdcData.V.value[0];
 HAL_setDacParameters(halHandle, &gDacData);

Maybe the problem is relatively elementary. I hope you can give me some advice.

Best regards

But the motor did not rotate.
