Driver interface and motor connection
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. |
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 terminal, and the other two terminals are respectively connected with VCC terminal and COM terminal.
Input analog signal (0-5V)

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.
Peaking current setting
Equipped with a motor protection function, the driver provides options to set desired current number in the P-sv ,knob to avoid over-current for motor. Please note that the random error is ±10% . The setting should be matched with motor rated current.
