6.2 conexiones de cableado
Carefully follow the wiring diagram provided with your flight controller. The ESC features solder tabs for motor output and designated pads for power input and signal connections.
- Entrada de energía: Connect the Red 14AWG wire to the positive (+) terminal and the Black 14AWG wire to the negative (-) terminal. An XT60 plug is included for battery connection.
- Salida del motor: Solder your motor wires directly to the designated M1, M2, M3, M4 solder tabs on the ESC. Ensure correct motor rotation direction, which can be adjusted in the BLHeliSuite32 software.
- Conexión de señal: Connect the signal wires from your flight controller to the corresponding signal pads on the ESC. Refer to your flight controller's manual for specific pinouts.
- Telemetría: The ESC supports real-time voltage and current monitoring. Connect the telemetry output to your flight controller if desired.
7. Instrucciones de funcionamiento
7.1 Firmware y configuración
The XRotor FPV 45A G2 ESC comes pre-installed with BLHeli-32 firmware. This firmware offers extensive customization options and supports various digital protocols, including DShot1200.
- BLHeliSuite32 Software: Use the official BLHeliSuite32 software to configure ESC parameters, update firmware, and reverse motor direction. This software can be downloaded from the official BLHeli websitio.
- DShot Protocol: Ensure your flight controller is configured to use DShot1200 or a lower DShot protocol for optimal performance and reliability.
- Damped Light Mode: This feature is enabled by default and provides active braking, allowing for quicker motor deceleration and improved flight characteristics.
7.2 Calibración
Typically, DShot ESCs do not require throttle calibration. However, if you are using an analog protocol (e.g., PWM, OneShot), refer to your flight controller's manual for the throttle calibration procedure.
8. Mantenimiento
- Regularly inspect all solder joints and wire connections for signs of wear or damage.
- Keep the ESC clean and free from dust, dirt, and debris. Use a soft brush or compressed air for cleaning.
- Check for any physical damage to the ESC board or components.
- Ensure the ESC is adequately cooled during operation. Avoid obstructing airflow.
9. Solución de problemas
- El motor no gira:
- Check all motor and signal connections.
