1.1 Hardware and GUI Setup

Below are the items that are required to run through this tuning guide.

  1. MCF8315EVM Board.
  2. A computer with the MCF8315A_GUI installed.
  3. A motor to be tuned using this process. It is reccomended to have motor data sheet but it is not mandatory.
  4. A DC Power Supply rated for the motor.
  5. Basic lab equipment such as a Digital Multimeter (DMM), Oscilloscope, current probe and voltage probes.
