Driver interface and motor connection




1.External potentiometer; 2.nput analog signal; 3.PWM pulse width.


Common port (0V reference level)


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


High level input the motor stops, low level input or when EN and COM are short circuit, the motor runs


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


The default output signal is 5V under normal circumstances; the level is 0V when malfunction occurs


Output pulse frequency signal(OC). The motor speed can be calculated through SPEED.

Four Speed regulation modes
Bulit-in potentiometer RV

Rotate the RV knob clockwise until a “click” sound, 
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.

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.
