Problem with KMS Current Control

Hi,

 

I generated the code from the KMS GUI and I was testing the current control. The motor speeds up pretty smooth using the interface. However, when I tried from the code generated, the motor tries to start apparently with much higher torque then a  fault comes up and the motor stops abruptly.

 

Here follows the code snippet I inserted in order to use current control:

 

if(GPIO_DRV_ReadPinInput(kGpioSW3) == 0){
   switch(user.state){
      case USER_BRAKE:
      user.state = USER_IDLE;
      break;
      case USER_IDLE:
      case USER_RUN_CURRENT:
      user.command.statorRefCurrent.q = _SQ(0.3/FULL_SCALE_CURRENT);
      user.state = USER_RUN_CURRENT;
      break;
      default:
      break;
   }
}
else{
   brake.config.brakingType = BRAKE_COAST;
   user.state = USER_BRAKE;
}

 

//Update drive module
DRV_updateSlowTick();

 

Could you please help me solve this problem?

Thanks
