Ultra low speed mode In the low-power state, the motor enters the ultra-low-speed rotation mode and push the throttle to the bottom. At this time, the digital power supply voltage has been increased to enter the normal power state, and the motor should still be in the ultra-low-speed rotation mode. The motor can enter the normal driving mode only when the throttle is reset to the initial state 5. Brakes The brake cable is a red 3P 51005-3P female shell interface cable. The interface is defined as red (+5V), white (signal pin), black (GND) and supports Hall type and switch type brake levers. (The switch type can be braked by shorting the red and white wires) When braking, the tail light flashes 6. Throttle The throttle cable is a white 3P 51005-3P female shell interface cable.
