How to use self-study:

When using the controller and the motor to work for the first time, should first use self-study wire.
Step 1. Connect the motor wire, Hall wire, battery wire, and other function wires.
Step 2, connect the self-study wire, the motor rotates forward, let it learn automatically for 10-20 seconds, disconnect the self-study wire, connect to other function wires, complete the self-study, and do not need to use it in the future.

How to set the P07:

1. if your motor have speed sensor wire ( some is the white wiring in hall), the P07 set to 1.
2. if your motor without speed sensor wire ( hall is 5 wiring) , so you must know your motor magnet number and motor gear ratio.
P07= magnet * gear ratio ( ex: magnet =20 , gear ratio= 1:4.5 , so P07 set to 20*4.5=90
