To initiate the configuration process, select SmartTune via the MotorStudio home page or the left-side navigation menu. Input the required motor parameters, including Rated Voltage, Rated Current, Rated Speed, and EVM Shunt Resistance value (5mΩ).
Select the appropriate load condition from Basic Information section in SmartTune page, Load for motors with mechanical load or No Load for motors without shaft load.
Choose the Control Mode that best suits your application requirements from the available device options, then click Generate Configuration button to start SmartTune.
Select the
adjacent to each text box to access additional information about the respective
parameters.
Figure 6-3 SmartTune Basic
ConfigurationSmartTune executes an algorithm that measures the motor's electrical parameters, including motor phase resistance, inductance, BEMF constant, and control loop coefficients based on the user-selected control mode. Additionally, it configures numerous parameters such as startup mode, open-loop current and acceleration rate, and various fault configurations necessary to achieve Level 1: Spin the motor functionality as highlighted in Figure 6-4.
Figure 6-4 Stages of TuningUpon successful completion of SmartTune, a Configuration Successful message appears below the Regenerate Configuration button and in the logs window. Users can then operate the motor by following the instructions provided in the Testing for Successful Startup into Closed Loop.

SuccessUsers can terminate the SmartTune execution process at any time by selecting the Terminate SmartTune button.
Under Performance Tuning, SmartTune allows users to select their Application and automatically generates optimal motor parameters. Users can also manually enter specific parameters such as Startup Method, PWM Frequency, and Startup Time as part of the performance tuning options. These manual configurations serve to override the SmartTune generated settings.
Figure 6-6 SmartTune Performace
TuningIf SmartTune fails to generate the motor tuning parameters, users may attempt to run the tool again by entering the motor parameters such as Phase Resistance (R), Phase Inductance (L), and BEMF Constant in the Motor Parameters (Optional) section.
Figure 6-7 SmartTune Optional
ParametersIf SmartTune fails to complete successfully, review the SmartTune FAQ page, which provides details on common failure conditions and their solutions.
In the event that SmartTune repeatedly fails to generate motor tuning parameters following the input of motor electrical parameters, users are recommended to configure motor parameters manually by following the applicable product specific tuning guide.
