2. If “OpenSDA-CDC Serial Port” is not printed out in the message box next to the “Port” drop-down menu, unplug and then
plug in the USB cable and reopen the FreeMASTER project.
Make sure to supply your development board from a sufficient energy source. Sometimes the PC USB port is not sufficient to
supply the development board.
8.2 MCAT FreeMASTER interface (Motor Control Application Tuning)
The PMSM sensor/sensorless FOC application can be easily controlled and tuned using the Motor Control Application Tuning
(MCAT) plug-in for PMSM. The MCAT for PMSM is a user-friendly modular page, which runs within FreeMASTER. The tool
consists of the tab menu, tuning mode selector, and workspace shown in
. Each tab from the tab menu represents one
sub-module which enables you to tune or control different aspects of the application. Besides the MCAT page for PMSM, several
scopes, recorders, and variables in the project tree are predefined in the FreeMASTER project file to further simplify the motor
parameter tuning and debugging. When the FreeMASTER is not connected to the target, the “Board found” line shows “Board ID
not found”. When the communication with the target MCU is established using a correct software, the “Board found” line displays
the same board name as "Board ID" variable watch and all stored parameters for the given MCU are loaded. If the connection is
established and the board ID is not shown, press
F5
to reload the MCAT HTML page.
MCAT may require internet connection. If no internet connection is available, CSS and icons may not be properly loaded.
