Kamoer Digital Temperature And Humidity Controller Stepper Motor Driver Board For Mini Peristaltic Pump

Product Description


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.



RS232, RS485 control speed, running

A) Setting the DIP switch (see Figure 2.2)

When RS232, RS485 control when you need to set the mailing address of  4460.3 driver ;

4 DIP switch BCD code corresponding to the four, 1-bit DIP switch for the highest bit, 4-bit DIP switch is the lowest bit.

DIP address: 0x00-0x0E correspond mailing address 0xC0-0xCE;

*Note: All dial to "ON", the knob for speed control function selection, 0xCF address is not available for the mailing address.

B)Connected to the communication line

a,When you need to use RS232 communication, plug the communication cable into the RS232 communication port P13; when you need to use RS485 communication, plug the communication cable into the RS485 communication port P14.

b,RS232 port definition: The terminal next to GND TX RX is corresponding to the definition of RS232 GND TXD RXD;RS485 port definition: The terminal next to the B G A is corresponding to the definition of RS485 B (D-)  GND A (D +);

C)Connect the KAS peristaltic pump to P1

D)Connect the power cord P10

E)Connect the power,send commands to control operation of the pump.

The current regulation (factory-adjusted)

A) Current regulator (current range 0 ~ 2A)

VR2: stepper motor current regulator potentiometer: clockwise to adjust the current increases, the motor torque is increased.

Generally in the case of easy motor out of step, increase the current (the proposed

current as small as possible, the large current , the more heating of motor).
