Quiet start(Except for special circumstances) strong power and power saving. The three-mode controller is a sine wave controller. It can operate in three modes, sine wave mode, square wave mode, and no hall mode (that is, it can be used without a hall sensor). The mode cannot be selected, the default is sine wave mode. When the hall sensor is damaged it will automatically switch to square wave mode. Runs no-Hall mode when no Hall sensors are connected. Suitable for in-wheel motors.Differential motor, etc. Tips: Applicable to a variety of motors, but only in-wheel motors with Hall sensors can use sine wave mode. When running other motors, it will automatically switch to square wave mode or no Hall mode. Installation Instructions Step 1. Connect wires 1, 2, 6, 8, 17. Step 2. Connect the No. 5 wire with the motor suspended. (Note: the motor needs to be in the overhang position for docking wire #5) Step 3. The motor will perform a forward/reverse state. (If there is a reversal you will need to disconnect the 5 wire and reconnect it) Wait 10 seconds in the forward state to complete learning. Step 4. Make the wiring connections according to the vehicle. Line Description 1.
