Circuit board features introduced

4460.3 stepper motor driver board can be four kinds of ways to control the stepper motor speed:

1. External Interface potentiometer P4 (the default)

2. Built in potentiometer VR1 (settable)

3. RS232 communication bus speed (P13)

4. RS485 communication bus speed (P14)

S1: P4 potentiometer or speed control potentiometer knob VR1 function selection set or mailing address;

P13: RS232 interface (PH 3Y connector);

P14: RS485 Interface (PH 3Y connector);

P10: Power input interface (input voltage range DC12 ~ 24V, XH 4Y connector);

P4: External speed potentiometer Interface (PH 3Y connector);

P1: Peristaltic pump stepper motor interface (XH 4Y connector);

P3: Knob to select the speed control circuit internally or externally, as an external speed (P3 2, 3 jumper cap short);

VR1: Built in potentiometer speed (potentiometer built elected governor when), clockwise to increase;

VR2: Stepper motor current adjustment potentiometer;

P2: Stepper motor stops used decay mode (default brake mixed-decay modes);

X2, X3, X4: Set segment (back of the board, the default segmentation 8) (Figure 1.3)

Note 1: 4460.3 driver board can connect with KAS, KCS, KDS etc. stepper motor driven peristaltic pump. The following descriptions as an example of KAS, same for KCS, KDS control methods, only connected to 4460.3 motor interface of the corresponding stepper motor pump.
