Which line of the electric vehicle controller is the speed line

The speed line of the electric vehicle controller is generally a black, red and green three-color line. The functions of each line are as follows:

1. The thin red wire is a positive 5V power supply;

2. The thin green line is the handle signal input;

3. The thin black wire is the grounding wire;

4. Black, red, and green color lines control speed;

5. The fine purple line is the speed of the instrument;

6. The fine brown line is the cruise speed;

7. The thin gray line is the speed limit line;

8. The thin yellow line is the automatic identification of the switch line.

It is important to note that the speed line of each brand of EV controller may be slightly different, but there is usually at least one red line, and the line is relatively thin. When wiring, please make sure that the positive and negative poles of the connection between the controller and the motor are correct, and if necessary, the positive and negative poles of the motor can be reversed. At the same time, the output power of the controller should be consistent with the power of the motor.
