Function

SV

1.External potentiometer; 2.Input analog signal.

F/R

High level input the motor will rotate anticlockwise, low level input or when F/R and DR- are connected, the motor will rotates clockwise.

BRK

Brake stop control signal: The motor brake stops when a high level is added or port suspension; the motor runs when the low level is added or DC- and BRK are connected.

 

 

 

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.

 

 

External potentiometer

Use a suitable potentiometer with a resistance value of 10KΩ, connect middle terminal with SV terminaland the other two terminals are respectively connected with VCC terminal and DC- terminal.

Quick brake

 

BRK and DC- are connected in default, the motor will rotate. When BRK and DC- are disconnected, the motor will be quick brake.

CW/CCW rotation

 

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