Quick Start GuideTWR-KV31F120M Tower System Module DemoProgram a PrecompiledExample Using theOpenSDA MSD Application51) Launch the Bootloader ModeWindows will detect a new TWR-KV31F12drive, a PEMicro OpenSDA Debugperipheral, an OpenSDA CDC Serial Portand will automatically install the requesteddrivers.Press and hold the reset (SW5) buttonwhile plugging in the USB cable; thenrelease it. Windows will detect a newBOOTLOADER drive and automaticallyinstall requested drivers.2) Load the OpenSDA P&E ApplicationsCopy and paste MSD-DEBUG-TWRKV31F120M Pemicro.SDA fromOpenSDA Applications folder in quick startpackage to the BOOTLOADER drive inmy computer/disk drive. Unplug and plugback the USB cable.plug back the USB cable. Computer willdetect a new TWR-KV10Z32 drive andautomatically install the required drivers.63) Program a Precompiled Example forthe KV3xIn the TWR-KV31F12 drive, copy anySREC file from the Precompiled Examplesfolder of the Quick Start Package. Demowill start automatically when the downloadis complete. To program a new demo,just copy any other SREC file. It is notnecessary to disconnect the USB cable.
freescale.com6Debug Your FirstIAR Project1) Load the OpenSDA P&E DebugApplicationIf you followed the previous exercise,you can jump directly to the followinginstruction; otherwise, follow section 5“Program a Precompiled Example Usingthe OpenSDA MSD Application” to loadthe OpenSDA P&E applications.2) Launch IAR EWARM and Buildthe Potentiometer lab ProjectOpen the IAR project file potentiometerdemo.eww following the path ProjectLabs\build\iar\kv31\Potentiometer lab inthe Quick Start Package.3) Run IAR EWARM, or later Debug ModeFrom the toolbar, click on Downloadand Debug.Note: If a Connection Manager window appears,check that your board is configured with theOpenSDA P&E Debug Application, then connectto the Interface OpenSDA Embedded TowerDebug-USB Port.Start the debug session by selecting theGO option from the toolbar. Rotate thepotentiometer to turn on LEDs D3, D4,D6 and D7. From the toolbar, suspend thedemo using the Break option. Select Stopto return to the Edit Mode.Clean the project before selecting theaction Rebuild All.Note: The compilation may return warningmessages without consequence.7
Quick Start GuideRunning 3-Phase PMSM Motor7TWR-KV31F120M andTWR-MC-LV3PH Set UpNote: Refer to the TWR-KV31F120M UserGuide at freescale.com/TWR-KV31F120M fordetailed jumper description.1) Load the OpenSDA P&E DebugApplicationIf you followed the previous exercise,you can jump directly to the followinginstruction; otherwise, follow Step 5 in theProgram a Precompiled Example Using theOpenSDA MSD Application section to loadthe OpenSDA P&E applications.2) Connect the boards and the motorConnect TWR-KV31F120M and TWR-MCLV3PH with the jumper setup shown in thetable below following the black and whitemarkings on the Tower System elevators.Connect the motor to the three-prongconnectors (J5) of the motor module.First, plug the 24V power supply includedin the TWR-MC-LV3PH kit into the barrelconnector (J1) of the motor module.Then, connect the USB cable to TWRKV31F120M and the computer.8TWR-MC-LV3PH: Jumper 31–2J131–2J101–2J141–2J111–2
freescale.com8Working withIAR EWARM9Monitor the Project withFreeMASTER1) Compile the PMSM Sensorless FOCDemo with IAR EWARMLaunch Freescale FreeMASTER from theWindows Start menu.Open the IAR project file PMSMSensorless FOC.eww following thepath Project Labs\build\iar\kv31\PMSM Sensorless FOC in the Quick StartPackage.Note: At first start-up, you may have an errormessage regarding the COM connection.Clean the project before selecting theaction Rebuild All.Note: The compilation may return warningmessages without consequence.2) Run IAR EWARM Debug ModeFrom the toolbar, click on Downloadand Debug.Open the FreeMASTER project file PMSMSensorless FOC.pmp following the pathProject Labs\Freemaster\PMSM SensorlessFOC in the Quick Start Package. Theapplication interface, PMSM SensorlessVector Control on Kinetis KV31, will appear inFreeMASTER. The speed, position, voltageand current consumption of the motor canbe monitored and controlled.Start the debug session by selectingthe GO option.9
Quick Start GuideIn the Project Options, set the COM portaffected to the OpenSDA -CDC Serial Port(info available in Device Manager) and setthe baud rate/speed to 19200 bps (checkthe option Do not Open Port at Startupto avoid error messages at FreeMASTERstartup).From the toolbar, select the actionFile- Start the communication.Press button SW1 of the TWRKV31F120M board to spin the motorcounterclockwise. Press the SW1 buttonagain to increase the speed of the motor.Press button SW2 to decrease the speedand stop the motor.Or, in FreeMASTER speedometer or speedselector box, select the requested speedand the motor will spin automaticallycounterclockwise or clockwise.In IAR EWARM, from the toolbar, suspendthe demo using the Break option, or selectStop to return to the Edit Mode.10
