3.3.3.2 Running the Application

Run the code by going to Run → Resume or clicking the Resume button in the tool bar. Check the following:

  • systemVars.flagEnableSystem should be set to 1 after a fixed time, meaning the offset calibration has been done. The fault flags, motorVars_M1.faultMtrUse.all, should be equal to 0.
  • To run the motor with current closed-loop control, set the variable motorVars_M1.flagEnableRunAndIdentify to 1 in the Expressions window. The motor will run with closed-loop control using the angle from the angle generator at a setting speed in the variable motorVars_M1.speedRef_Hz. Check the value of motorVars_M1.speed_Hz to confirm that the two values are very close.
  • Change the value of Idq_set_A.value[1] in the Expressions window to set the reference torque current. The motor phase current will be increasing with the same percentage accordingly.
  • Set the variable motorVars_M1.flagEnableRunAndIdentify to 0 to stop the motor. Terminate the debug session and power off the power supply to the inverter board.
