3. Operating Instructions

The FOC controller is designed for intelligent and stable operation, incorporating multiple protection features to ensure safety and longevity.

Protection Features and Functions

Figure 5: Overview of the controller's multiple protection performance features.

• Soft and Hard Start Switch: Allows selection for a smooth or powerful initial acceleration. Soft start ensures a gentle beginning, while hard start provides immediate, strong power.
• Locked-Rotor Function: The controller automatically limits the current when the motor is blocked, preventing damage to the motor and controller.
• Undervoltage Protection: When the battery voltage drops below a safe threshold, the controller stops output and enters a protection state to prevent battery over-discharge.
• Over Temperature Protection: If the controller's internal temperature exceeds a safe limit, it will automatically power off or reduce power to prevent overheating damage.
• Speed Protection: Prevents overspeeding caused by poor speed regulation or malfunction, enhancing safety.
• Mute Protection: Reduces operational noise according to the characteristics of brushless motors, providing a quieter ride.

4. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your controller.

• Keep Dry: Protect the controller from water and excessive moisture. While the aluminum casing offers some protection, direct exposure to water can cause damage.
• Cleanliness: Periodically clean the exterior of the controller to remove dust and debris, especially from the heat sink fins, to ensure efficient heat dissipation. Use a soft, dry cloth.
• Check Connections: Regularly inspect all wiring connections to ensure they are tight and free from corrosion. Loose connections can lead to intermittent operation or damage.
• Avoid Physical Damage: Protect the controller from impacts or excessive vibration, which can damage internal components.

5. Troubleshooting

If you encounter issues with your controller, refer to the following common troubleshooting steps:

• No Power/Controller Not Responding:
  • Check the main power supply connections (Positive and Negative Power Supply wires) to ensure they are securely connected to the battery.
  • Verify the key switch connection (Key Switch wire) is properly engaged and providing power.
  • Check the battery voltage to ensure it is within the 48-72V operating range and not depleted.
• Motor Not Running/Erratic Behavior:
  • Inspect the motor's three-phase lines (Three Phase Line of Motor) and Hall sensor connections (Motor Hall) for proper seating and continuity.
  • Ensure the throttle input is correctly connected and functioning.
  • If the controller enters a protection state (e.g., undervoltage, over temperature), address the underlying cause (charge battery, allow cooling).
• Brake Not Functioning:
  • Check the connections for the High Level Brake and Low Level Brake wires.
  • Verify the brake levers or sensors are functioning correctly.
• Anti-Theft System Issues:
  • Ensure the Burglar Alarm Signal and Anti Theft Device Power Supply connections are correct.
  • Consult the anti-theft device's specific manual for further troubleshooting.

If problems persist after performing these checks, it is recommended to consult a qualified technician or contact the manufacturer for further assistance.
