Why is my bike, equipped with a VOTOL EM85 controller and a QS middrive 2000W motor, not starting with good or aggressive torque?

The VOTOL EM85 controller is programmable and allows for fine-tuning of various parameters to match your motor and riding preferences. If your bike is not starting with good or aggressive torque, you should investigate the controller's settings using the programming software (LD-EM-V3). Here are some areas to check within the programming software: Basic Settings: Review the 'Basic Settings' page (Figure 5.1 in the manual) for options related to current limits and throttle settings. Adjusting these could impact starting torque. Sport Mode Setup and Flux-Weakening Compensation: The 'Sport mode setup' and 'Flux-Weakening compensation' page (Figure 5.2) allows for advanced performance adjustments that can affect power and speed. Ensure these are configured to provide the desired aggressive torque. Motor Settings: On the 'Motor Setting' page (Figure 5.3), parameters like pole pairs, motor type, and Hall shift angle are configured. Incorrect settings here can lead to suboptimal motor performance, including starting torque. Throttle Response: The programming software allows you to adjust throttle response. A less aggressive throttle response setting could be contributing to the issue. Additionally, consider these general troubleshooting steps: Connections: Ensure all wiring connections, especially for the motor phase wires (U, V, W) and Hall sensor wires, are secure and correctly matched. Loose connections can lead to intermittent operation or reduced performance. Throttle Function: Verify that the throttle is correctly connected and functioning, providing the expected 0-5V output. Brake Signals: Check for any active brake signals that might be overriding the throttle or limiting power. If you are unsure about any configuration or connection, it is recommended to consult a qualified technician or the manufacturer's detailed wiring diagram and support channels.
