1 DDCS-Expert Brief Introduction
1.1 Product Brief Introduction
Thank you for your interest in our standalone motion controller and for taking the time to
read this manual.
Digital Dream is a numerical control company specializing in the research, development
and production of various CNC (Computer Numerical Control) systems since 2008. Digital Dream
aims to combine high quality and high reliability with affordability.
The DDCS Expert is a 3~5 axes motion controller for open or close stepper and servo systems
with 7/10.2 full color display screen. The highest output pulse per axis is 1MHz. The users can
self-define the functional keys. This controller supports multiple spindle mode, support straight
Tool Magazine, gantry type Magazine, disk type magazine. The Operation system interface even
though very comprehensive, can be learned in very short time.
The DDCS Expert numerical control system adopts the ARM+FPGA design framework. ARM
controls the human-computer interface and code analysis and the FPGA provides the underlying
algorithms and creates the control pulse. This guarantees reliable control and easy operation.
The internal operating system is Linux based.
The DDCS Expert can be used for many styles and types of CNC machines. Lathes, Routers,
Pick&Place and Mills, lathe and cutters are just a few examples. The DDCS Expert operates as a
Stand Alone system without the need of a computer. This guarantees high precision, accuracy
and reliability.

1.4 Explanation of Abbreviations
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 DDCS is connected to 24V DC. Obey and follow the electrici-
ty safety rules of your country when connecting this equipment.

DDCS-Expert controller creates a self-defined IO ports method. According to the user’s
favorite, the users can define the input and output ports as which they want. In the IO page,the
users can define the input port and output port, and also can inpect the input/output port and
MPG status.
Power on the DDCS-Expert controller, system popup the main page, and press F4 Key to go
to the IO Port Page:

Show the input ports or output ports are on the short-circuit or not.
If the little block becomes Red,the according port is on the short-circuit; if it’s still black,the
according port is not on the short-circuit.
For example, we define the IN01 as the “X-axis Zero Signal”, and when the X axis touched the
limited switch, it will show as below:
But,the status is active, doesn’t mean that the according signal is active. For example,we
reverse the signal’s polarity, and moves the X axis away from the limit switch, the status light
and IO block show as below: the X-axis zero signal is active,and IN01 Block is not on,because
IN01 is not conductiong with COM-.

Shows MPG setting status.As the following figure shows, the MPG current setting is X10,in Y
axis; “-54” block is the calculator of wheels turnning step; “0” block shows the the current
cursor position.
So now we finished the indroduction on the IO port.Only when the users understand how to
set the IO port and how to inspect the IO page,it will help us on Wiring.
Here we move the X axis to touch the limit switch, but status light doesn’t light up.So the
Status shows the signal is active or not, the IN01-IN24 Block shows the port is conducting or not.
Column 3:
Column 6: Open the output signal;
Column 7: Close the output signal;
Column 8: Change the Polarity to the reverse.
Figure 3-6 The Signal is not active but port in conducting

4 Wiring
DDCS-Expert wiring board, there are about 7 parts as following:
1) System Power and IO Power supply input Ports; 2) Driver Signal output Ports; 3) Input
and Output Ports; 4) Spindle Output Ports; 5) MPG Port; 6) Ethernet and USB interface; 7)
HMI/RS232 interface.

DDCS-Expert needs two power supplies,Main power is for controller system,IO Port power is
for Input and Output and MPG ports. Both power supply is 24VDC,current is 3A.In the System
Power input port ,the marked 24V and GND is the main power input ports;In the IO power input
ports,the COM+ and COM- is the power input ports for Input/Output Port and MPG.Please keep
in mind,only when the two power supplies are connected correctly the controller can be work
properly.
Many new users only give system power,then the limited switches,the relay,and MPG and
spindle don’t work at all,then please go to check if you also give power to IO ports.
IO power gives the power to all the IO ports,include the Limited switch,Relay,MPG,Etop and
all other Input and output Ports,without it,spindle,MPG,Input and Output ports cannot work.
In order to avoid electrical noise it is highly recommended to use two separate 24V power
supplies.
In order to avoid high-frequency electrical noise from power supply cable,it is highly recom-
mended to intall a noise filter at the power input to the switch power supply.
