Four speed regulation modes
Build-in potentiometer RV
Rotate the RV knob clockwise, the motor starts to run and accelerate. Motor speed will decrease if anticlockwise.
When it gets to a limited position, the motor stops.
Use a suitable potentiometer with a resistance value of 10KΩ, connect middle terminal with SV terminal, and the other two terminals are respectively connected with VCC terminal and COM terminal.

BRK and COM are connected in default, the motor will be quick brake, When BRK and COM are disconnected, the motor will rotate.
Connect F/R and COM, the motor will rotate clockwise, disconnect it, the motor will rotate anticlockwise.
