Digital Dream has a 20 years history in the numerical control industry, specializing in the research, devel-

opment and production of various CNC (Computer Numerical Control) systems. DigitalDream aims to combine

high quality and high reliability with affordability. We produce 1 axis to 6 axes CNC system.

Thank you for choosing digital dream’s motion controllers.With a lots of examples and charts,this manual

will describe the features,functions and every operations of our controllers.Pls read this manual carefully before

any assembling and using.Incorrect handling can result in injury and damage to persons and engraving

machine.Pls keep the manual carefully for convenient to read it at any time in need.

DM500 is very professional 4 Axis CNC Motion Controller which is based on embedded system.DM500

operates as a standalone system without the need of a computer,and with a pendant,it makes users very conve-

nient to opreate the machines.Our controller adopts Embedded Operating System,by which the controller will

never get virus-infected.And the controller adopts look-ahead algorithm by which the the controller can read

more ahead 30-lines G-code than the operating.All the features guarantees high precision,accuracy and reliabili-

ty.And the size is very small,oepreation is very easy,very suitable for all size of Engraving machines,Milling

machines and cutting machines and so on.

1.1 Introduction of Product

1.2 Performance parameter of the DM500

Page -1 DM500 User’s Manual

The DM500 motion controller contains the handheld motion controller,circuit switching wiring board,and

HDMI digital high-definition transmission cable.

The handheld motion controller and wiring board are communicated by 2 Meter 37 pins HDMI digital

high-definition transmission cable which is shielding twisted-pair cable to avoid interference.

The wiring board can be installed by DIN linearguide ways No. C45.

When operating the DM500 Controller, the users will come across some English abbreviations. Here a list

with explanations

FRO: Feed Rate Override

SRO: Spindle Rate Override

SRJ: Jog Speed Setting

F: Feed rate, unit is mm/min

S: Spindle Speed, unit rev/min.

X: The coordinate code of the X axis.

Y: The coordinate code of the Y axis.

Z: The coordinate code of the Z axis.

A: The coordinate code of the A axis

BUSY: The system is busy. You still can adjust FRO and SRO

READY: READY mode, any operation can be done

RESET: Reset mode, controller is in “OFF” mode, no operation can be performed

MPG: MPG mode. Operate the machine with the MPG (Manual Pulse Generator)

AUTO: Run G code. Auto is showing when file is processing

Keep away from exposure to moisture or water. This product contains sophisticated electronics

and must not get wet.

Wiring warning: the IO input terminal of this controller supports equipment with source power (such as

Inductive Proximity Switch ). When using this kind of equipment, pay attention to the polarity. Avoid the

+terminal to be connect with GND. This controllers has analog output for spindle control (0-10V). Please avoid

this terminal to ever connect with GND as damage to the controller may occur.

Operation warning. Please observe all security measures when operating the machine. The ESTOP

must be connected and properly labelled. In case of a problem, press the E-stop at once to avoid

damage to humans, animals and the equipment.

High voltage danger. The DM500 is connected to18-32V DC. Obey and follow the electricity safety

rules of your country when connecting this equipment.

Notice:

1. The users should prepare two power supply switch for each controller.One is for the controller

system,one is for the Inputs and Output ports.

2. 24V GND is the power supply for the controller,COM+ and COM- is the common terminal for Input

and Output ports.

3. The Low voltage for input signal is effective.By default it is the NPN switch.

4. The pulse and direction signal is differential output.

2.3 The Wiring Board Ports Description

2.3.1 The Power Supply Wiring

In general, the power supply of industrial control’s equipment products are complex. They have many

different ground levels. The internal power structure of this product is as follows:

It’s recommended to add a filter to prevent the electric interference.

The power for input/output ports is 24VDC,the power for Main controller system is also 24VDC.Because

inside of the controller system,the power design for input/output ports and main controller already isolated,its

recommended to give them two independent power supply.

Main controller use the same power supply with Input/output ports.(no recommended).
