As the Marked No. 2 from Picture 5-2,there is the Stepper/Ser-
vo Interface.The device can be used to control machine tools
with stepper or servo motor controls with pulse and direction
signals.The option for users is 3-6 axis.

As Picture 5-1 showed,No.3 terminal block is for Spindle control output. We define the interface from left are
GNDs,VSO,OUT1,OUT2,Index. They are Ground of output, Speed adjusting voltage,Digital output1, Digital
output2, Spindle speed feedback input.
Take Nowforeuer inverter as the example. Spindle control output and the inverter connection showed as
Picture 5-6.X1 control spindle Clockwise RUN and STOP, AIN1 modify spindle's speed. if we need to control
spindle anti-clockwise RUN and STOP, we need to connect X2 to OUT2.

VSO connects to Speed adjustment which defined by voltage 0-10V.
The relationship Max. Spindle speed and current spindle speed is as below:
VSO(Output Voltage)=10*current spindle speed(S)/Maximum Spindle Speed(Max.S).
For example if we set the Max Speed is 24000,and we need the current spindle speed is 18000,then
VSO=10*18000/24000=7.5V.
The following picture 5-7 is the setting method of Max. speed in Mach3 software.

From the Picture 5-1 shows,the Marked No. 9 is for adjustable
input interface,which must be operated by the digital potenti-
ometer.The interface will make us to operate the FRO,SRO
and SJR very Easy and convenient.The Interface should be
operated with position switch and digital potentiometer,for the
FRO,SRO and SJR adjustment.
If there is no connection between COM- and SRO or COM-
and SJR,the default is FRO Active,it means it is in the term of
‘Feed rate override’.When there is connection between COM-
and SRO,it is in the terms of ‘Spindle speed rate override’;if
there is connection between COM- and SJR,it is in the term of
‘Jog Mode’.

5.9 LED Indicator for Power and communication with Mach 3 software
As the Picture 5-1 show, There are 3 Indicator LEDs for the controller power,IO Power and communicai-
ton with Mach3 respectively.
If the controller and IO power supply are configurated in right way,the Main Power LED and IO Power
LED turn to Red.
The LED marked “CONN” represents the status of the communicaton with Mach3 software.If a link has
not been established,the LED will not light.

6.2 Open Mach3 Software and connect with right PlugIn file
Double-click the icon mach3mill .Enter into Mach3 software. Pop-up the plug-in box as
below left picture.Then Click “Create Profile” and name it to “DigitalDream”,click “Default profile values” and
confirm it by “OK”
6. Mach 3 Configuration
When you purchase our product, we will supply a software package in the U-disk, which contains “Digit-
alDream” PlugIn,and the EC500 Manual.
In your computer which you will run the EC500 controller,you must already installed the Mach 3 Software,and
now pls copy the PlugIn in to C:\Mach3\PlugIn.(If the user install the Mach 3 software in C-disk.)
6.1 PlugIn
UC300 User’s ManualPage -14Digital Dream Mach3 Motion Controller

After Click “OK”,it will popup a window of the option for DLL file as below,pls choose “Digital Dream” as
below.Then press OK. If you do not want to the dialog box to show again any more, select ‘Don’t ask me this
again’.If connect successfully,Status bar will show “EC500 device is connected to your computer”.
Click config plugins in the software main menu,in the pop-down menu select ‘PluginConfig’,it will show the
DigitalDream Plug-In is enabled:
6.3 Check UC300 Plug-In in the Mach3 software
UC300 User’s ManualPage -15Digital Dream Mach3 Motion Controller

Mach3's Menu -> Config -> Motor Tuning (and Setup).
The Step Pulse and Direction Pulse fields are used for a Ethernet Port connection from your computer to
your hardware.
The Steps per Unit, Velocity (Units per Minute) and Acceleration fields are critical for tuning your
motors. The Steps per Unit is determined by your hardware for each axis. The velocity is the maximum
speed you want your axis to move. The acceleration is the maximum acceleration rate your motors should run
at (to prevent stalling or missed steps). This needs to be done for each of your axes.
Don’t forget to save the data when you finished the data setting of every axis.For example,you click Z
Axis,and save all the datas into the column,then you must click “SAVE AXIS SETTING”,then the datas can
be saved.
6.4 Motor Tuning and Setup
Click Main Menu ‘Config’,select the ‘Motor Tuning’ from its pop-down menu:
Then the screen display as below:
UC300 User’s ManualPage -16Digital Dream Mach3 Motion Controller

This page is to select the stepper motor control pins. Because Stepper motor control pins address are fixed by
the controller board, So here only need to define the Pin address(No.s),we can define other parameters meter.
To make sure the Z axis to the right direction(Up is ‘+’,down is ‘-’), Z axis’s “Dir low” should be set to”√”.Oth-
er axes’s should be set as the user’s request.
Second, make sure that you have your home switches assigned correctly (Menu -> Config -> Ports & Pins ->
Input Signals). While you could use a single input for your X, Y, Z, and A homes, it is much better to have them
as separate inputs! Our EC500 controller has plenty of inputs available and it allows Mach to home all of your
axes at the same time if you wish (although you typically have your Z axis home after the rest of your axes so
you don't crash your head).
6.5 Port and Pins Setup
First, make sure you have your Motor Outputs assigned correctly (Menu -> Config -> Ports & Pins as below:
Then go to Right Lables: Motor Outputs and start to configurate as below:
UC300 User’s ManualPage -17Digital Dream Mach3 Motion Controller

Here you can configure according to your actual needs the corresponding function. Optional Function include
XYZABC 6axis’s Upper and lower limit、XYZABC 6axis’s HOME point. We set upper limit and home of
XYZA to 3456 corresponding IN3/IN4/IN5/IN6 of the Controller board.
