Device Power supply Solution
The power supply solution in the field of the Industrial automation is always very
complicated, there is a lot of the GND, now we descript the structure of the power supply as
below:
The power supply structure as the Figure 2-1,main power supply input and MPG module and
stepper control output module are common GND, Limited and Estop input module and Spindle
speed adjust M3/M8/M1 module are common GND, between main power supply and output
module there are photoelectric isolation. The inputs of limited switch and Estop and so on are
Common anode, inside of the device, there is +12VDC as common+, no need to connect external
power supply. Based on the reference of output GND interface, output a 0-10V adjustable voltage
to adjust the spindle speed,M3/M8/M10 digital output interface is open-GND. If connect an
external relay, need to output GND to refer to, and give the relay an external power supply.
Product connection define and method
As the Figure 2-2 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.
1.USB port
As the Figure 2-2 showed, Marked No. 1 position is the USB port. Mach3 connect to this
board through the USB port.
2 Main power input
As Figure 2-2 showed,No.1 terminal block is Main power input interface, need input
12-40V/above 20W. There is silkprint "+" and "-",See as figure2-2,left terminal is "+" and right terminal is "-".
3 Limit/Home/Estop/Probe input port
As the Figure 2-2 showed, 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.

3 lines Proximity Switch connection Figure 2-5,brown cable for Proximity switch connect
with 12V,Black cable connect channel, blue cable connect with GND1. Only support NPN 3lines proximity switch.
4 Serial expansion interface
As the Figure 2-2 showed, Marked No. 4 position is Serial expansion interface . We can
extend some other equipment from this interface.Definition of the port is RXD,TXD,GND from left to right.
We define the interface from left are: GND1(Output GND),VSO(0-10V adjustable speed
output),OT1,OT2,OT3,OT4.
Take Nowforeuer inverter as the example. Spindle control output and the inverter connection
showed as Figure 2-7.If ACM and DCM are closed,only need to connect one port.
VSO real output voltage=10V*s spindle setting speed/max spindle speed.Forexample,if max
spindle speed is 24000,current spindle speed is S=18000,so the VSO output voltage=10*18000/24000=7.5V.
Max. spindle speed setting ports as showed sa Figure 2-4,open it from Pulley from Menu
config. The current spindle speed can be set by S directive or Mach 3 spindle setting speed module.
Set Machine Coordinate system
Firstly Open the software,as the drawing 5-1 shows,at this time,the software can operate the
machine movements,but before the setting machine coordinate system,there is no connection
between the software and machine.So first step is to set the machine coordinate system
1 Set the machine original position switch
As our request,some machine set the original point at the coordinate positive direction,some
machines set the original point at the coordinate negative direction.Mach 3 can search out the
machine original point direction by the software setting.As the pic 5-2 shows,open Homing on the config menu.Then as pic 5-3 shows.On this page,Home Neg is for searching for the machine orginal point direction, × means searching original point at negative direction; √ means searching original points at the positive direction.As the pincture 5-3 shows,X axis’s original position is at the negative direction,Y and Z’s original points are at the positive direction.
2 Set soft limits
As Figure 5-3 shows,this page also can set machine soft limit points,Soft Max is positive
direction soft limited points,soft Min is negative direction soft limited points.The soft limited
points values is according the references to the machine coordinate system,so as this example
shows,Y and Z axis’s max value is 0,all the effective coordinate data is less than 0.As the Figure shows,according to our current request,we set our XYZ axis soft limited points area as [0,270] [-390,0] [-100,0].
3 Searching for machine original points
As Figure 5-4 shows,press REF ALL HOME at main display page,then XYZ A4 start to
search for the original points,if you need more axis’s operation,edit macro command,or press
Alt+7 into Diagnostics display page,you can search original point for every axis. Diagnostics
