• Terminals: Function
• SV: 1.External potentiometer; 2.input analog signal; 3.PWM pulse width.
• COM: Common port (0V reference level)
• F/R: Motor rotation direction control(CW/CCW). High level input the motor will rotates clockwise, low level input or when F/R and COM are short circuit, the motor rotate anticlockwise
• EN: High level input the motor stops, low level input or when EN and COM are short circuit, the motor runs
• BRK: The motor brake stops when a high level is added or port suspension; the motor runs when the low level is added or EN and BRK are connected
• ALM: The default output signal is 5V under normal circumstances; the level is 0V when malfunction occurs
• SPEED: Output pulse frequency signal(OC). The motor speed can be calculated through SPEED.

Function

Four Speed regulation modes

Bulit-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.

External potentiometer

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.

Quick brake

BRK and COM are connected in default,

the motor will be quick brake .When BRK

and COM are disconnected, the motor will rotate.

CW/CCW rotation

Connect F/R and COM, the motor will rotate clockwise, disconnect it, the motor will rotate anticlockwise.
