3.Production appearance and size

1. After the revision,V4 version using the red PCB board, PCB size is 135.3*82.5mm.;

2. The front of the narrow edge placed with USB communication interface and DB9 hand control interface for the convenience of customers drawn from the case panel directly;

3. The back-end of narrow edge is power input and output interface and 3 relay output interface; relay is strong interference source, relay away from the design of main control chip, it is conducive to the stability of the board;

4. One of the two wide sides is stepper motor and principal axiscontrol signal output;

5. The another side of two wide sides is the emergency stop, manual speed input, limiting input interface; one side for the input, another side output connection mode is simple and convenient;

6. 5V and 12V power module compact independence, security, stability;

7. External ensure the stability of the system work effectively with crystal active and main control chip shield;

8. The software is USBCNC,not mach3,pls note!

 

4.Detailed functional introduction

A. Card input voltage: 15~36V;

B. Limit port working voltage: 12V;

C. Stepper motor control signal output voltage: 5V;

D. External power supply voltage: 12V;

Note: marked 15~36VDC is input interface, marked 12V is output interface, can not wiring wrong.

 

5.Function and definition of each module

A) USB interface, connect to the computer USB port through this interface,you can use the software usbcnc to control this board, this USB interface is the square B interface,please use USB2.0 connection cable which with shielding and magnetic and not to exceed 2 meters in length.

B) Hand control box interface, external hand control box can use this interface to access the system, the interface is standard DB9 form, its definition as shown in the following table.

C) Power indicator, as shown in figure the above D10 indicator is the front-end USB power indicator, this light lit up after USB port connection with computer , D2 in below is the back -end power indicator light, this light also will lit up when board card work power access with it.

 

 

 

D) Board card firmware upgrade button UP and reset button RST, firmware has been updated, so upgrade button don?t need to use, reset button be used when need to restart due to the board fault.

 

 

 

E) Manual speed control interface,wiring connection mode as shown in the following figure .
