Function

Input

SV

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

COM

Common port (0V reference level)

F/R

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

EN

High level input the motor will slowly stops, low level input or when EN and COM are connected, 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

Output

ALM

The fault output signal of the motor or drive is 5V under normal circumstances; the level is 0V when a fault occurs.

SPEED

The output of speed is pulse frequency corresponding to the motor running. The terminal can be connected to upper computer

 

 

 

 

 

Four speed regulation modes

 

Build-in potentiometer RV

 

 

Rotate the RV knobs clockwise until a “click” sound, the motor starts to run. Rotate the RV knobs clockwise, the motor will accelerate. Rotate the RV knobs anticlockwise, motor speed will decrease, and the motor will stop until a "click" sound.

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 REF+ terminal and COM terminal.

Input analog signal (0-5V)

 

When the input voltage is 0.25V, the motor speed is 5% of the maximum speed;  When the input voltage is about 4.7V, the motor speed is the maximum value.
