Motor and ESC Calibration

"Fine-tune motor and ESC settings in AeroGCS Config with our calibration guide." Motor and ESC Calibration

a) Motor Testing

To access Motor testing and ESC calibration options, navigate to the RPA Config menu and select the "MOTOR and ESC" section. Upon accessing this menu, you will encounter a screen displaying available choices for both Motor testing and ESC calibration.

Within the screen, you'll find four motors, which are visible because the quad option has been chosen in the airframe settings. Additionally, a motor slider is present, allowing you to enable or disable data for each motor. Towards the bottom of the screen, there's a calibration button.

Note: It is mandatory to calibrate ESC before the motor test.

In this section, you can perform motor testing for various devices such as quadcopters and hexacopters. Depending on the selected frame type, the screen will display the corresponding number of motor test sliders. For a quadcopter, it will show four sliders, and for a hexacopter, it will display six sliders, as illustrated in the image below:

Note: Remove the propellers from the device before the motor test.

b) ESC Calibration

During ESC Calibration in the RPA Configuration menu, Electronic Speed Controllers (ESCs) play a crucial role in controlling motor speed and direction, relying on the PWM input signals received from the flight controller (FC). The ESCs are designed to operate within a specific range of PWM input values, which can vary, even among ESCs of the same model.

The purpose of this calibration process is to update all the ESCs with the maximum and minimum PWM input values that will be provided by the flight controller. Consequently, this ensures uniform and consistent responsiveness of all ESCs and motors to input commands from the flight controller throughout the entire range of input values.

To perform Electronic Speed Controller (ESC) calibrations within the AeroGCS Config, follow these steps:

Step 1. Go to the AeroGCS Config.

Step 2. Navigate to the "RPA Configuration" section.

Step 3. Locate the "Motor and ESC Calibration" section.

Step 4. Scroll down until you find the "ESC Calibration" section, as illustrated in the diagram below, to initiate the ESC calibration process.

Step 5. Select the "Calibrate" button and then follow the on-screen instructions that will guide you through the steps necessary to calibrate all of your ESCs. Ensure that you complete this calibration process for each ESC.

Steps for calibrating your ESCs:

Here are the steps for calibrating your ESCs:

Step 1. Disconnect both the USB connection and the battery to power down the flight controller.

Step 2. Connect the battery.

Step 3. If your vehicle is equipped with a buzzer, you will hear the arming tone.

Step 4. If your flight controller has a safety button, press it until it turns solid red.

Step 5. Listen for two beeps in a musical tone.

Step 6. After a few seconds, you will hear a series of beeps, with each beep corresponding to the number of battery cells you are using.

Step 7. Finally, listen for a single, long beep, indicating the endpoints and successful completion of ESC calibration.

Step 8. Disconnect the battery and proceed to power up the system normally.

This marks the completion of the motor testing and ESC calibration process.
