FarDriver ND96890 Controller Instruction Manual

1. Introduction

The FarDriver ND96890 is a sine wave FOC (Field-Oriented Control) brushless DC (BLDC) motor controller featuring a self-learning function. It is generally compatible with QS and Yuma motors. For new motor brands, some parameters may require self-testing and adjustment. This controller utilizes a ONE-LIN protocol, ensuring compatibility only with displays that support the same protocol.

Please note that due to factory adjustments, the DC or phase current values may vary slightly (lower or higher) from the described specifications. However, this variation is minimal and does not affect the overall performance of the controller.

5. Operation

5.1 Mobile Application Interface

The FarDriver controller can be configured and monitored via a dedicated mobile application, accessible through the included Bluetooth adapter. The app provides real-time data and allows adjustment of various parameters.

Figure 4: FarDriver Mobile Application Interface

The application interface typically includes sections for:

• Current Parameters: Displays real-time bus current, phase current, and other electrical values.
• Motor Parameters: Shows motor-specific settings like pole pairs, rated speed, and rated power.
• Rotation Limit Ratio: Allows setting maximum RPM limits (e.g., 500RPM to 9000RPM).
• Three-Speed Limit: Configures low, mid, and high-speed limits for current and RPM.
• Throttle Parameters: Adjusts throttle response, including low and high thresholds.
• Diagnostic Data: Provides information such as voltage, temperature, and phase current readings.

Connect the Bluetooth adapter to the controller's program port, then pair your mobile device with the adapter to access these settings. Follow the on-screen instructions within the app for parameter adjustments and monitoring.

7. Maintenance

To ensure the longevity and optimal performance of your FarDriver ND96890 controller, follow these general maintenance guidelines:

• Keep Clean: Regularly clean the exterior of the controller to prevent dust and debris buildup, especially around the heat sink fins, which can impede cooling.
• Inspect Connections: Periodically check all wiring connections for tightness and signs of corrosion or damage. Loose connections can lead to poor performance or electrical issues.
• Avoid Extreme Conditions: Protect the controller from excessive moisture, extreme temperatures, and direct impact. While designed for vehicle use, prolonged exposure to harsh conditions can reduce its lifespan.
• Software Updates: Check for any available firmware updates for the controller via the mobile application to ensure you have the latest features and bug fixes.

8. Troubleshooting

If you encounter issues with your FarDriver ND96890 controller, consider the following:

8.1 Functional and Interface Issues

Most controllers are universal versions and not custom-made for specific vehicle brands. Therefore, after installation, some auxiliary functions of your original vehicle (such as speedometer display) may not operate as expected. Many functional interfaces may require modification rather than being plug-and-play.

Action: Before making any modifications, carefully review the function lines on your original vehicle and the communication signals of the speedometer. Consult a professional if you are unsure about wiring or modifications.

8.2 General Malfunctions

If the controller is not functioning correctly, first check all power and signal connections as per the wiring diagram (Figure 3). Ensure the battery is adequately charged and providing the correct voltage. Use the mobile application (Figure 4) to check for any error codes or unusual parameter readings.

9. User Tips

For optimal performance and safety, consider these user tips:

• Professional Installation Recommended: Due to the complex nature of electric vehicle conversions and the need for precise wiring and parameter tuning, professional installation or assistance from an experienced technician is highly recommended.
• Careful Parameter Tuning: When adjusting parameters via the mobile app, make small, incremental changes and test the vehicle's response thoroughly. Incorrect settings can lead to unexpected behavior or damage.
• Motor Matching: While the controller is generally compatible with QS/Yuma motors, always verify the specific motor's electrical characteristics (e.g., KV rating, pole pairs) against the controller's capabilities to ensure a good match.

10. Warranty and Support

10.1 Warranty Information

A 1-year warranty is offered for motors and controllers. Please note that the buyer is responsible for covering the return shipping costs for any repairs or replacements under warranty.

The warranty does not cover man-made damage. If you lack experience in assembling electric kits, please exercise caution when purchasing, as improper installation or use may void the warranty.
