• SVMC Normal Size: 247mm*146mm*62mm
• SVMCxx060 Size: 215mm*146mm*62mm

5. Operation and Configuration

5.1. Software Interface Overview

The MQCON controller can be configured using a computer via a USB cable or a smartphone via Bluetooth. The computer interface mirrors the phone app interface.

5.2. Ignition Connection

The orange ignition wire must be connected to the battery positive terminal to power on the controller.

5.3. Brake Functions

• H-Brake (High Brake): If the purple wire is connected to 12V, the controller enters brake status. Disconnecting from 12V exits brake status.
• L-Brake (Low Brake): If the yellow wire is connected to 0V (battery negative), the motor will stop running.

Note: High brake and low brake functions cannot be used simultaneously.

5.4. Reverse Function

To activate reverse, connect the white wire to 0V (battery negative). The controller will enter reverse status, and twisting the throttle will cause the motor to spin in the reverse direction. Disconnecting the white wire from 0V exits reverse status.

5.5. 3-Speed Function

The controller supports a 3-speed function, configurable as either a button-activated mode or a switch-activated mode.

• 3-Speed Mode (Button):

  

  When '3 Speed (button)' is selected in the software, use a momentary button (resets itself) to connect the pink wire and ground wire. Each press and release will cycle through the speed gears: 3-2-1-2-3... When powered on, the controller defaults to 3rd gear (high speed mode).
• 3-Speed Mode (Switch):

  

  When '3 Speed (switch)' is selected in the software, use a physical switch to control the speed modes:

  • Connect the pink wire and ground wire: Enters high speed mode.
  • Connect the transparent wire and ground wire: Enters low speed mode.
  • Disconnect both pink and transparent wires from ground: Enters middle speed mode.

  

5.6. 0-5V E-Brake Throttle

This function allows for regenerative braking controlled by a separate throttle. Connect a dedicated throttle to the specified terminal. Select the “Ebrake-throttle” mode in the software. When this throttle is twisted, the controller will engage the e-brake, with braking strength proportional to the throttle position. The maximum braking strength can be adjusted via the “Electric brake phase current” setting in the software.

5.7. Motor Temperature Function

The controller supports the KTY83-121 temperature sensor, typically located inside the motor. This function can be enabled or disabled through the controller software.

5.8. Hall Angle Configuration

The Hall angle is a critical parameter for the MQCON controller. Different motor types require different Hall angles for optimal performance. If the Hall angle is incorrect, the motor may not run efficiently.

If you do not know the correct Hall angle for your motor, use the automatic testing function in the software. For QS V1 or V2 type motors, the Hall angle is typically around 65. For QS V3 type motors, it is around 250.

5.9. Software Connection

The MQCON controller can be connected to a computer via a USB cable or to a smartphone via a Bluetooth adapter for parameter configuration.

• USB Connection: Before connecting to a computer, install the necessary USB driver and software provided by the controller manufacturer.

Ensure the USB cable is connected correctly as shown:

• Bluetooth Connection: Use the provided SVMC Bluetooth Adapter to connect the controller to your smartphone for app-based configuration.

6. Maintenance

Regularly inspect all wiring connections for tightness and signs of wear or damage. Ensure the controller is mounted in a location that allows for adequate airflow to prevent overheating. Keep the controller and display clean and free from dust and moisture. The IP54 waterproof rating provides protection against splashes, but avoid submersion.

7. Troubleshooting

If you encounter issues with your Sabvoton controller and display kit, consider the following:

• General Connection Issues: Always ensure all connections are correct and secure before powering on the system.
• Motor Compatibility: The SVMC series controller cannot be matched with QS mid-drive motors or other brand hub motors with a Hall angle of 60°. The Hall angle for QS hub motors is typically 120°.
• Software Error List: The MQCON software interface includes an 'Error list' tab that can help diagnose issues such as 'anti-theft', 'reverse', 'release throttle err', and 'throttle-err'. Consult this list if the system is not functioning as expected.
• TFT Speedometer: This specific SVMC72150 model does not natively support TFT speedometers. If you intend to use a TFT speedometer, custom wiring harness and communication protocols may be required.

8. User Tips

• E-Brake Functionality: The 0-5V e-brake function has been updated. You can now achieve e-brake functionality without needing to press a separate brake switch, offering more flexible control.
• CA Function: Custom Cycle Analyst (CA) functions are no longer directly supported. However, a drawing can be provided to guide you on how to connect with your CA displayer if needed.
• Software Access: Contact the seller to obtain the necessary links and passwords for downloading the controller manuals and software (USB driver and configuration tool) before or upon receiving your controller.

9. Warranty and Support

Please note the following regarding warranty and support:

• There is no warranty for 'unlocked type' controllers and the SVMC96100 controller (even if it's a normal type).
• If you are unsure about connecting the controller with your motor or other components, please contact the seller for assistance.
• For access to programmable software and user manuals, contact the seller to receive the download links and passwords.
