NVCM USB Mach3 Stepper Motor Motion Control Card Breakout Board 6 Axis 125KHz

Introduction

• Novusun CNC has engaged in the Numerical control industry for 7 years,specialized in the research,development and production of various CNC controller systems with high quality and high reliability.

• NVCM ONLY supports Mach3 software, through USB port to communicate with computer.

Products specification

• Support USB;

• 16 ports photoelectric isolated input interface;

• 16 ports photoelectric isolated output interface;

• 1 port 0-10V spindle speed analog output interface(can change to PWM output);

• can support 6 axis stepper systems maxisim,125KHz pulse output for every axis;

• ARM motion control chip;

• main device is 24V-32V DC power supply input,current should higher than 1A;

As the Figure showed, the connection of the controller includes power supply interface, USB connection interface, Stepper/Servo control output interface, spindle control output interface, Estop and limited switch and tool setting input interface and so on.

Now we descript them in details as below.

1.USB port

• As the Figure showed, Marked No. 1 position is the USB port. Mach3 connect to this board through the USB port.

2.Main power input

• No.1 terminal block is Main power input interface, need input 24-32VDC/above 20W. There is silkprint "+" and "-",left terminal is "+" and right terminal is "-".

3.Limit/Home/Estop/Probe input port

• Marked No. 3 position is the input port. they are the optical isolated Input interface.

• The silkprint INP1 INP2 GND INP3 INP4 INP5 INP6 INP7 INP8 INP9 GND IN10 IN11 IN12 IN13 IN14 IN15 IN16 GND 12V on the board connect to PIN1-16 of the mach3.

4.Serial expansion interface

5.MPG port

6.Universal output interface 2

7.Spindle control output/ Universal output interface 1

8.Stepper motor driver port

Stepper motor driver port

• As the Figure show, The marked No. 8 are 6 axis stepper motor controller port.

• They are X/Y/Z/A/B/C from left to right.

• Each axis's pin is defined as COM+/CP-/DIR- from left to right.

Ps: also can support servo motor/servo motor driver,same wirings as the stepper motor driver.

MPG&Output port

Substantival explanation

• FRO: Feeding adjust: During the operating process, the F value already set, and need to adjust the current feeding speed, then we can adjust FRO value to realize it.

• SRO: Spindle speed adjust: During the operating process, the S value already set, and need to adjust the current spindle speed, then we can adjust SRO value to realize it : Current Speed S#=setting S*SRO.

• SRJ: speed adjust manually,During the operating process,as the manual speed already set,and we need to adjust the current speed,and impossible to fix the value during it is working,then we can revise the SRJ value to realize it. Current manual speed FS#=Setting manual speed*SRJ.

• F:Feedingspeed,the unit is mm/min.For example F=200,means every minute feeding 2000mm.

• S: Spindle Speed. Unit is rad/min.For example S=20000,means 20000 revolution/Minute.

• X axis Coordinate Y axis Coordinate

• Z axis Coordinate

• A axis Coordinate

• B axis Coordinate C axis Coordinate

• Ready:ReadyMode.In the mode we can do any operation,include processing or values modification or starting 2nd mode.

• Reset: Reset mode.In this mode,it should stop every operation.

• Step: Manual Step Mode. Every axis candonduct the manual step operation at this mode.

• MPG: MPG mode.Every axis can conduct the MPG operation at this mode.
