The MCAT tuning tool plug-in module is in the FreeMASTER GUI. This tool is targeted at
motor-control applications, where you can change the motor-control parameters or adjust the start-up
and control parameters. Each tab represents one submodule of the embedded-side control, and tunes its
parameters. For more information, see Sensorless BLDC Control on Kinetis KV (document AN4642).
Here are the basic instructions:
• To start the motor, set up the required speed using the speed slider.
