Key App Features:

• Motor Parameters: Configure pole pairs, rated speed, back speed, rated voltage, rated power, and thermic probe settings.
• Current Parameters: Adjust maximum DC current, maximum phase current, and stop/max back current limits.
• Rotation Limit Ratio: Set various RPM limits (e.g., 500RPM, 1500RPM, up to 8500RPM).
• Three-Speed Limit Ratio: Define low and mid-range current and RPM limits for different speed modes.
• Throttle Parameters: Set low and high throttle thresholds.
• Real-time Monitoring: View power, RPM, voltage, line current, phase current, battery capacity, MOS temperature, controller temperature, and throttle position.
• Control Functions: Buttons for CANCEL, FOLLOW, ANGLE TEST, and AUTO LEARN for motor parameter calibration.

6.2. Self-Learning Function

The controller's self-learning function allows it to adapt to different motors. Utilize the 'AUTO LEARN' feature in the mobile app to calibrate the controller with your specific motor for optimal performance.

6.3. Flux Weakening Function

The controller supports flux weakening, which can extend the motor's operating speed range beyond its base speed. This feature can be configured via the mobile application.

7. Maintenance

• Regular Inspection: Periodically check all wiring connections to ensure they are secure and free from corrosion or damage.
• Cooling System: As this is a liquid-cooled controller, regularly inspect the cooling lines and ensure the cooling system is functioning correctly to prevent overheating.
• Cleanliness: Keep the controller free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
• Firmware Updates: Check with the seller or manufacturer for any available firmware updates to ensure optimal performance and access to new features.
• Avoid Disassembly: Do not attempt to disassemble the controller without explicit permission from the seller, as this may void your warranty.

8. Troubleshooting & FAQs

If you encounter any issues, please refer to the following common questions and advice:

• Q: The controller is not responding or functioning correctly.
  A: Ensure all wiring connections are correct and secure according to the wire definition diagram. Verify that the power supply voltage matches the controller's rated voltage. Use the mobile app to check for error codes or abnormal parameter readings.
• Q: How do I match the controller with a new brand motor?
  A: While the controller generally matches well with QS Motors, for other brands, some parameters may need to be tested and adjusted manually via the mobile application's self-learning function.
• Q: What should I do if I have problems after wiring the motor and controller?
  A: Please contact the seller immediately for assistance. Do not attempt to disassemble the controller without seller permission, as this will void the warranty.
• Q: How can I get the user manual and software for programming?
  A: Please contact the seller directly to obtain the link and password for downloading the manuals and software. It is recommended to do this before or upon receiving your controller.

9. User Tips

• Always confirm your system's voltage, motor RPM, wheel size, and desired climbing performance with the seller before finalizing your order to ensure compatibility and optimal setup.
• Take advantage of the mobile application's real-time monitoring features to keep an eye on your system's health and performance.
• For customized motor applications, be aware that production times may be extended if the motor is not in stock. Plan accordingly.

10. Warranty and Support

The FarDriver controller comes with a warranty period of 3 months to 1 year, depending on the specific component. For the motor, the warranty is typically one year and three months, while other parts have a one-year warranty.

Important Notes:

• Please contact the seller to confirm specific parameters before production; otherwise, the product will be produced as default.
• If the motor is not in stock and requires customization, please allow at least 15 additional days for order preparation.
• When placing an order, please provide your email address so the seller can provide the manual and software.
• Read the manual carefully before wiring the motor and controller. If you encounter any problems, contact the seller promptly. Disassembling the product without seller permission will void the warranty.
