You can watch the video or follow the below step-by-step guide to set up your MCSPTE1AK144:
Jumper | Setting | Option | Description |
---|---|---|---|
J104 | 1-2 | Reset Signal | Reset signal to OpenSDA, use to enter into Open SDA bootloader mode |
2-3 | Reset signal direct to the MCU, use to reset S32K144 (default) | ||
J107 | 1-2 | Board Powering | S32K144 powered by 12 V power source (default) |
2-3 | S32K144 powered by USB micro connector | ||
J109/J108 | Open | CAN | CAN termination resistor is disconnected |
Short | CAN terminator resistor is connected (default) |
Jumper | Setting | Option | Description |
---|---|---|---|
J8 | Short | HALL/Encoder interface | Voltage level for HALL/Encoder interface is 3.3 V |
Open | Voltage level for HALL/Encoder interface is 5.0 V (default) | ||
J9/J10/J11 | 1-2 | Motor Type | Bidirectional 3-phase current sensing for PMSM FOC (sinusoidal) motor control |
2-3 | 3-phase back-EMF voltage sensing for BLDC six-step (trapezoidal) sensorless motor control |
1. Ensure default S32K144EVB and DEVKIT-MOTORGD jumper options.
2. Ensure jumper J107
in S32K144EVB and DEVKIT-MOTORGD is in position 1-2 for powering board from 12 V power supply.
3. Place DEVKIT-MOTORGD jumpers J9
, J10
,
J11
to position 1-2 for PMSM application or 2-3 for BLDC application, The jumper
J8
stays open for 5 V HALL sensors.
4. Make sure the potentiometer for overcurrent comparator is set in position (slightly to the left from the middle) for approximately 8 – 10 A.
Ensure that the motor phase wires are in the following order, from phase A to phase C:
Connect the 12 V power supply for the S32K144EVB and DEVKIT-MOTORGD boards, together with the 3-phase PM Motor. S32K144EVB is configured for powering from DEVKIT-MOTORGD board. Keep the DC
supply voltage within the range of 8 to 18 V.
Note: The DC power supply voltage affects the maximum motor speed.
Connect S32K144EVB to the PC using the USB cable.
Note: Allow the PC to automatically configure the USB drivers if needed.
Let's take it for a test drive.
Select the appropriate PMSM or BLDC motor control application from the installed directory NXP\MCSPTE1AK144\sw.
Reprogram the MCU using S32 Design Studio:
To import the installed application software project in the S32 Design Studio IDE for Arm®:
NXP\MC_DevKits\MCSPTE1AK144\sw
and choose appropriate project and click
OK. Then, click Finish.Optional: These steps should not be necessary since they are automatically executed in the next step.
In the S32 Design Studio menu click Run > Debug Configuration and select the predefined debug configuration and click on Debug to start loading built code into MCU.
To let the code run, click Resume (or press F8), and use Disconnect to avoid interference between the S32DS IDE debugger and the FreeMASTER tool.
1. Launch the FreeMASTER application.
2. To open the *.pmp
FreeMASTER project <selected project>\FreeMASTER_control
, click File > Open Project.
Note: You can also start it by double clicking directly in the S32DS project folder.
3. To enable communication, in the FreeMASTER tool bar, click Go (or press CNTRL+G).
Successful communication displays in the status bar at the bottom as:
RS232 UART Communication;COMn;speed = 115200
1. To display the application control page, click the App Control tab on the Motor Control Application Tuning Tool menu.
2. Configure the motor rpms and turn on the motor drive.
When the power supply is connected to the DEVKIT-MOTOGD board, the application is in a READY states - steady green LED on S32K144EVB board. RGB LED also indicates:
Check pending faults
In case of pending faults, click the Clear FAULT on the FreeMASTER MCAT control page, or alternatively press and simultaneously hold
SW2
and SW3
on the board.
Start application
To initiate clockwise/counterclockwise spinning of the rotor, click ON/OFF on the control page or press SW2/SW3
on the
board.
Set speed
To set the speed, change the speed required variable. Go to the variable watch window by clicking speed gauge, or by pressing the switch
SW2/SW3
.
Stop application
Stop the application by clicking ON/OFF button on the FreeMASTER MCAT control page or simultaneously press and hold
SW2
and SW3
on the S32K144EVB board.
