4. Sąranka ir diegimas
Before powering on the controller, ensure all connections are correct. The SVMC series controller is not compatible with QS Mid drive motors or other brand hub motors with a 60° Hall angle (QS hub motors typically use a 120° Hall angle). This type of SVMC72150 also does not support TFT speedometers; custom wiring and communication may be required if a TFT speedometer is used.
4.1 Sujungimo schema
Refer to the following diagrams for proper wiring of the SVMC controller and its connection to other components.


4.2 Specific Connections
- Orange Ignition Wire: This wire should be connected to the positive terminal of the battery.

Figure 8: Ignition wire connection. - Brake Wires:
- H-Brake (Purple Wire): Connect the purple wire to a 12V source. When connected to 12V, the controller enters brake status. Disconnecting it from 12V exits brake status. This is typically connected to the 12V brake wire of a hand brake or foot brake.

Figure 9: H-Brake wire connection. - L-Brake (Yellow Wire): Connect the yellow wire to 0V (battery negative). When connected to 0V, the motor stops running. This is typically connected to the ground wire.

Figure 10: L-Brake wire connection.
Svarbu: High brake and low brake functions cannot be used simultaneously.
- H-Brake (Purple Wire): Connect the purple wire to a 12V source. When connected to 12V, the controller enters brake status. Disconnecting it from 12V exits brake status. This is typically connected to the 12V brake wire of a hand brake or foot brake.
- Reverse Function (White Wire): If the white wire connects to 0V (battery negative), the controller enters reverse status. Twisting the throttle will then cause the motor to spin in reverse. When the white wire disconnects from 0V, the controller exits the reverse status.

Figure 11: Reverse wire connection. - 0-5V E-Brake Throttle: Use a separate throttle to connect to the terminal. In the software, select the “Ebrake-throttle” mode. When this throttle is twisted, the controller will enter the e-brake mode, and the brake strength will follow the throttle position. The maximum strength can be set from “Electric brake phase current” in the software.

Figure 12: 0-5V E-Brake throttle connection. 
Figure 13: E-Brake mode selection in the software. - Motor Temperature Function: The controller supports KTY83-122 temperature sensors from inside the motor. This function can be enabled or disabled from the software.

5.1 Programming and Monitoring
The MQCON controller can be connected to a computer via a USB cable or to a phone via Bluetooth for programming and monitoring. The computer interface and phone app interface are identical.
- Kompiuterio prijungimas: Before connecting to a computer, install the USB driver and volume software provided by the controller manufacturer.

Figure 16: USB driver and software files. Ensure the USB cable is connected correctly:

Figure 17: USB cable connection for programming. - Bluetooth ryšys: The Bluetooth module should be connected as shown in the diagram.

Figure 18: Bluetooth module connection.
For detailed instructions on using the computer software to set parameters, please contact the seller for the "MQCON controller application user manual" and "MQCON (Sabvoton) FOC Controller Parameter Manual-EN".
5.2 Hall Angle Setting
The Hall angle is a critical parameter for the MQCON controller. Different motor types require different Hall angles for optimal performance. An incorrect angle may lead to suboptimal motor operation.
- If the Hall angle is unknown, use the automatic testing function in the software to determine it.
- If known, input the correct angle directly. For SVMC series controllers used with QS V1 or V2 motors, the Hall angle is approximately 65. For QS V3 motors, the angle is approximately 250.

5.3 3-Speed Function
The controller supports two modes for the 3-speed function:
- 3-Speed Mode (Button):
- Select "3 Speed (button)" in the software.

Figure 20: 3-Speed (button) selection. - Use a momentary button (resets itself) to connect the pink wire and ground wire.
- Each press and release of the button cycles through the speed gears: 3-2-1-2-3...
- Upon power-on, the controller defaults to 3rd gear (high speed mode).
- Select "3 Speed (button)" in the software.
- 3-Speed Mode (Switch):
- Select "3 Speed (switch)" in the software.

Figure 21: 3-Speed (switch) selection. - Use a dedicated 3-position switch for this mode.

- Connect the transparent wire to ground for low speed mode.
- Disconnect both pink and transparent wires from ground for middle speed mode.
- Select "3 Speed (switch)" in the software.
6. Priežiūra
The Sabvoton SVMC72150 V2 controller is designed for durability with an IP54 waterproof rating.

7. Problemų sprendimas
If you encounter issues with your controller, refer to the following general troubleshooting steps:
- Nėra galios: Check battery connections and the orange ignition wire connection to ensure it's properly connected to battery positive.
- Variklis Neveikia:
- Verify all motor phase wires (U, V, W) and Hall sensor connections are correct and secure.
- Check the Hall angle setting in the software. An incorrect Hall angle can prevent the motor from running optimally. Use the automatic testing function if unsure.
- Ensure no brake signals (H-brake or L-brake) are active.
- Check the throttle connection and functionality.
- Unexpected Braking: Check if the H-brake or L-brake wires are inadvertently connected or if the 0-5V e-brake throttle is being activated unintentionally.
- Reverse Function Issues: Ensure the white reverse wire is correctly connected to 0V when reverse is desired and disconnected otherwise.
- Software Connection Problems:
- For USB connection, ensure the USB driver is installed correctly and the cable is connected as shown in Figure 17.
- For Bluetooth connection, ensure the module is correctly wired (Figure 18) and your device's Bluetooth is enabled and paired.
The controller software includes an "Error list" (Figure 23) that can provide diagnostic information. Consult this list if available during troubleshooting.

If issues persist, contact the seller for further assistance, providing details of the problem and any error codes displayed.
8. Vartotojo patarimai
- Always double-check all wiring connections before applying power to prevent damage to the controller or other components.
- When adjusting parameters via the software, make small, incremental changes and test the system's response to avoid unexpected behavior.
- Keep the controller's firmware updated if new versions are released by the manufacturer, as this can improve performance and fix bugs.
- Consider mounting the controller in a location that allows for good airflow to aid in cooling, especially during high-power operation.
9. Garantija ir palaikymas
For controllers that are an "unlock version" (configured for higher amps), please note that there is no warranty service provided. However, the manufacturer may offer suggestions and technical advice.
For access to programmable software and user manuals, including detailed parameter settings, please contact the seller directly to obtain the necessary links and passwords. It is recommended to acquire these documents before or upon receiving your controller.
