5. Setup and Wiring Connection
Proper wiring is crucial for the safe and correct operation of your ESC. Refer to the diagrams below for connection details.
5.1 General Wiring Overview
- Battery Connection: Connect your LiPo battery (3-13S) to the main power input wires (red for positive, black for negative). Ensure correct polarity.
- Motor Connections: Connect the three phase wires from each motor to the corresponding outputs on the ESC. For dual motor setup, connect both motors.
- Receiver Connection: Connect the signal wire (SIN), 5V, and GND from your receiver to the designated pins on the ESC. This typically uses a standard servo connector.
- Throttle Handle: If using a physical throttle handle, connect its signal, 3.3V, and GND wires to the appropriate ADC pins on the ESC.
5.2 Detailed Pinout and Connections
The detailed diagram shows the various ports and their functions:
- 1. CAN: For inter-ESC communication in multi-ESC setups.
- 2. SENSE: Sensor ports for sensored motor operation.
- 3. COMM: Communication ports (TX, RX) for external modules.
- 4. SWD: Debugging and programming interface.
- USB: Micro USB port for connecting to a computer for configuration via VESC Tool.
- Dual/Single Mode Switch: A switch is present to select between dual motor operation (ON) or single motor operation (OFF).
Ensure all connections are firm and correct before applying power. Incorrect wiring can damage the ESC or other components.
6. Operating Instructions
The Flipsky Dual FSESC4.20 is configured using the VESC Tool software. This software allows for detailed customization of motor parameters, battery settings, control modes (DC, BLDC, FOC), and safety features.
- Software Installation: Download and install the latest VESC Tool software from the official VESC project website.
- Connect to PC: Connect the ESC to your computer using the provided Micro USB cable.
- Initial Setup: Launch VESC Tool and follow the motor setup wizard to configure your motors and ESC. This includes detecting motor parameters, setting current limits, voltage cutoffs, and calibrating your remote control.
- Mode Selection: Choose the appropriate motor control mode (BLDC or FOC) based on your motor type and desired performance characteristics. FOC generally offers smoother and quieter operation.
- Testing: After configuration, perform a low-power test to ensure motors spin correctly and respond to throttle input as expected. Gradually increase power during testing.
Always refer to the VESC Tool documentation for detailed instructions on advanced configuration and troubleshooting.
7. Maintenance
- Regular Inspection: Periodically inspect the ESC for any signs of physical damage, loose connections, or burnt components.
- Cleaning: Keep the ESC clean and free from dust, dirt, and debris. Use compressed air or a soft brush for cleaning.
- Heatsink: Ensure the anodized aluminum heatsink is free from obstructions to allow for optimal cooling.
- Firmware Updates: Check for and install firmware updates for the VESC periodically to benefit from performance improvements and bug fixes.
- Storage: Store the ESC in a dry, cool environment when not in use.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor not spinning | Incorrect wiring, low battery, motor detection failure, incorrect VESC Tool settings. | Check all wiring connections. Ensure battery is charged. Rerun motor detection in VESC Tool. Verify throttle calibration. |
| ESC overheating | Excessive load, insufficient cooling, incorrect motor parameters. | Reduce load. Ensure adequate airflow around the heatsink. Review motor current limits in VESC Tool. |
| Intermittent operation | Loose connections, interference, faulty sensor wires. | Check all connectors for tightness. Ensure sensor wires are properly connected or try sensorless mode. Check for radio interference. |
| ESC not detected by VESC Tool | Faulty USB cable, driver issues, ESC not powered on. | Try a different USB cable. Install necessary USB drivers. Ensure ESC is powered on (connected to battery). |
9. User Tips
- For optimal performance and longevity, always configure your ESC using the VESC Tool to match your specific motor and battery setup.
- Consider using FOC mode for smoother acceleration and quieter operation, especially in sensitive applications.
- Regularly monitor the temperature of your ESC during initial runs to ensure it's operating within safe limits.
