Start your application
1. Connect the micro USB cable to
J116 (bottom side) if not already connected.
If necessary, install the driver to make the COM port available as an OpenSDA port, which can be checked under COM & LPT ports in the device manager.
Note: You will be able to see the OpenSDA – CDC Serial Port if the driver is available.
2. Go to the device manager and right click the COM port detected and select Update Driver Software.
Select Browse My Computer for driver software and select the OpenSDA driver that has been downloaded.
Restart your machine.
3. Connect power supply 24 V to the inverter and micro USB cable to micro USB port on the development board.
Turn on the power switch.
Note: Make sure the status LEDs for voltage levels 3.3 V (
D14), 5 V (
D15), 1.25 V (
D16) and 12 V (
D32) supply are lighting green on the controller board.
4. Open Tera Term on Windows PC and select the serial port to which the micro USB of the development board is connected and click OK.
Go to Setup > Serial Port and select 19200 as the baud rate.
5. After resetting the board by pressing the reset button (
You will be able to see this welcome message on the terminal:
6. Run the Device Manager on your system.
Check which COM port was assigned to the OpenSDA – CDC Serial Port.
7. The power stage cannot be powered without the controller board when Brake Resistor (
J2) is populated.
The absence of the controller board leads to a high BRAKE_GATE signal, and a large current flows through the BRAKE_RESISTOR, creating a considerable burn
hazard as the resistor will dissipate enough heat to harm on contact. If PWM braking is used, software must explicitly control the BRAKE_GATE signal. Thus, the power stage
board must always be connected to the controller board.
- a. Connect the micro USB cable to the MCSPTR2A5775E controller board and the host PC.
- b. Connect the controller board to the power stage using PCIe connector
- c. Connect the 24 V power supply to the power stage. The controller board power supply is taken from the power stage.
Note: Make sure to perform these steps in correct order.
8. Start the FreeMASTER project MCSPTR2A5775E.pmp located in MCSPTR2A5775E_Z7_0\ FreeMASTER_control project directory.
Click on Project\Options menu, choose the RS232 COM port number that was assigned to the virtual COM port driver and set the communication speed to 115200
Enable communication by pressing the START button in FreeMASTER or by pressing <CTRL+K>.
9. Start the application by pressing 1 - “RUN” on the flip/flop (ON/OFF) switch on the FreeMASTER control page, or by positioning the RUN/STOP switch (
on the power stage board) to the RUN position (transition from STOP to RUN in case the switch was in the RUN state when a fault event occurred).
10. Stop the application by pressing 0 - “STOP” on the flip/flop (ON/OFF) switch on the FreeMASTER control page, or by positioning the RUN/STOP switch (
on the power stage board) to the STOP position.
Note: You can RESET the application anytime by pressing the
SW1 on the MCSPTR2A5775E
