current into the inverter

Steve Ressler

Hi,

I'm looking for the easiest way to report the total dc current into the inverter using instaspin-foc, so that I can report the motor current to a user. Is there a variable in the instaspin system that contains this value? Or do I need to create it myself?

Thanks.

Something like this?

    // read Id and Iq vectors in amps
   gMotorVars.Id_A = _IQmpy(CTRL_getId_in_pu(ctrlHandle),_IQ(USER_IQ_FULL_SCALE_CURRENT_A));
   gMotorVars.Iq_A = _IQmpy(CTRL_getIq_in_pu(ctrlHandle),_IQ(USER_IQ_FULL_SCALE_CURRENT_A));

   // calculate vector Is in amps
   gMotorVars.Is_A = _IQsqrt(_IQmpy(gMotorVars.Id_A, gMotorVars.Id_A) + _IQmpy(gMotorVars.Iq_A,     gMotorVars.Iq_A));
