Motor Control I/O Board User’s Manual To control the motor from a GUI on your PC, conn ect a serial cable to the J9 RS-232 port on the MC-IO board and rebuild the code with the GUI macro option as described later in this manual. Figure 5. Standalone Oper ation Three seconds after power up, the LED displays the current set speed.
Motor Control I/O Board User’s Manual condition is displayed on the seven-segment LED. For details on the protection functions implemented in hardware, consult the user’s m anual for MC-PWR-LV low-voltage power module. The sample code software also has built-in fau lt detection algorithms as an extra m easure of protection.

Motor Control I/O Board User’s Manual through the on-chip debugging emulator and the source code displayed in the Debugger window as shown below. Figure 14. Source Code in Debugging Window 2. Use the RUN command to execute code in debugging m ode. At this point, the motor can be controlled from the user interface in standalone mode or GUI m ode.
Motor Control I/O Board User’s Manual 10. GUI Operation To operate the motor from the PC GUI, the code has to be rebuilt with “GUI” option. Select Compiler Options from PM+ Tool me nu and type “GUI” in Preprocessor Define Macro entry. Figure 15.
Motor Control I/O Board User’s Manual The GUI will launch if the connection is established: Figure 17. BLDCM GUI 2. To operate the motor, use the controls in the GUI. 3. To change the PID parameters click on the tuning key symbol Figure 18. Launching PID Parameter Window The tuning window will allow the changing of P, I or D constants: Figure 19.
