Fardriver NS72450/NS84450/NS96450 Electric Motorcycle Controller User Manual

1. Introduction

The Fardriver Electric Motorcycle Controller is a sine wave type brushless DC controller featuring a self-learning function for optimal performance. It is designed to work efficiently with QS Motors and can be adapted for other motor brands with appropriate parameter testing. This manual provides essential information for the setup, operation, and maintenance of your Fardriver controller, including models NS72450, NS84450, and NS96450.

2. Key Features

• Constructed with imported, high-performance Moss tubes.
• Utilizes an aluminum substrate scheme for efficient heat dissipation, with Moss tubes laid on the aluminum substrate and then placed on the PCB board.
• Compact design for easy integration.
• High efficiency, resulting in low temperature rise and small running current.
• Equipped with a self-learning function for excellent commonality across various setups.
• Companion mobile application compatible with both Android and Apple devices.
• Features a flux weakening function (note: the product itself does not contain magnetism).

3. Setup and Installation

Before installation, ensure all components are present. The controller package includes the main controller unit, a wiring harness, mounting screws, and a Bluetooth adapter. Fardriver controllers are available in two main versions: Hall version (e.g., NS72450, NS96450) and Encoder version (e.g., NS72450B, NS96450B). The 'B' suffix indicates an encoder version.

This diagram includes connections for Hall sensors (HALLA, HALLB, HALLC), communication lines (85A/RXD, 85B/TXD, CANH, CANL), power (B+, B-, 60VC, BWSV), and control signals (SV, ACC+, FD, P, ALARM, W, RE, SPA, KEY, FW, FW2). Note the slight differences in pin labels compared to the Hall version.

4. Operating Instructions

The Fardriver controller is programmable via a dedicated mobile application, which connects using the included Bluetooth adapter. This app allows for monitoring real-time data and adjusting various parameters.

4.1 Mobile Application Usage

Download the official Fardriver application from your device's app store (compatible with Android and Apple). Connect the Bluetooth adapter to the controller and pair it with your mobile device. The app provides a dashboard for monitoring and a professional debug settings page for advanced configurations.

The self-learning function allows the controller to adapt to your motor's characteristics. For new motor brands, it is recommended to perform parameter testing to ensure optimal compatibility and performance.

5. Maintenance

To ensure the longevity and reliable operation of your Fardriver controller, follow these general maintenance guidelines:

• Keep the controller clean and free from dust, dirt, and moisture.
• Regularly inspect all wiring connections to ensure they are secure and free from corrosion or damage.
• Avoid exposing the controller to extreme temperatures or direct sunlight for extended periods.
• Ensure adequate ventilation around the controller to prevent overheating.

6. Troubleshooting

If you encounter issues with your Fardriver controller, consider the following basic troubleshooting steps:

• No Power/No Response: Check all power connections, including battery and ignition. Ensure the controller is receiving adequate voltage.
• Motor Not Spinning: Verify motor phase wire connections and Hall sensor connections (if applicable). Use the mobile app to check for error codes or unusual readings.
• Erratic Behavior: Re-check all wiring for loose connections or shorts. If using a new motor, ensure the self-learning function has been properly executed or parameters have been adjusted.
• Bluetooth Connectivity Issues: Ensure the Bluetooth adapter is correctly plugged in and powered. Restart your mobile device and the controller.

For more advanced diagnostics, utilize the Fardriver mobile application's debug settings to monitor real-time data and identify specific fault conditions.

7. Specifications

Below are the main specifications for the Fardriver NS series controllers:

7.1 NS72450 Series Specifications

7.2 NS96450 Series Specifications

Note: The NS84450 model shares similar characteristics with the NS72450 and NS96450 series, primarily differing in its specific voltage range within the Fardriver NS series.

8. User Tips

• Motor Compatibility: While Fardriver controllers generally pair well with QS Motors, if you are using a motor from a different brand, it is crucial to perform parameter testing and adjustments using the mobile application to ensure optimal performance and prevent potential issues.
• Controller Version Identification: Fardriver controllers come in Hall and Encoder versions. Models with a 'B' suffix (e.g., NS72450B, NS96450B) indicate an encoder version, which requires specific motor feedback. Ensure you have the correct controller version for your motor.
• Aesthetic Variation: Be aware that the controller units may come in blue or black colors, which are sent randomly. This does not affect functionality.

9. Warranty and Support

The Fardriver controller comes with a 1-year warranty from the date of purchase. This warranty covers manufacturing defects and malfunctions under normal use. For any issues encountered during usage, please contact the seller or manufacturer's support channel for assistance. The buyer is responsible for return shipping costs for warranty repairs or replacements.

It is recommended that users have adequate knowledge of electric kit assembly and conversion before installing this product. Professional installation is advised if you are unsure about any steps.
