1. Handle accelerator: suitable for conventional handles, potentiometers, pedal accelerators, etc. 2. Brake power-off: default low-potential brake power-off 3. Speedometer: default speed signal, voltage type 4. Anti-theft alarm: low-potential anti-theft anti-theft alarm, When someone pushes the cart in the parking state, the controller locks the motor, and the anti-theft alarms. 5.

The default speed scale is 80%/100%/115%. 6.1:1 power assist: The 1:1 power assist function is mainly used for pedal electric bicycles. A power sensor is installed on the pedal shaft, and the controller detects the signal output current of the sensor. At this time, you will feel an increase in strength when riding, which is easy and labor-saving. 7. Self-learning: Connect the power line, motor phase line, Hall line, electric door lock line, throttle line, plug in the self-identification line (self-learning line) after confirmation, and the motor will run automatically. If the motor does not turn on and turns to correct operation for 2-3 seconds, disconnect the identification line (learning line), and the identification is completed. If the motor reverses, disconnect the identification wire and plug it in immediately. The motor automatically switches to forward rotation. Disconnect the identification line (learning line) after 2-3 seconds of operation.
