DM800 is the 3-5 axis motion controller we spend 2 years to design.
DM800 is a CNC system without computer. Only need a U-disk within G-CODE file,
DM800 can read the G file and run the G file.
This manual introduces operation, connection and usage schedule of our professional
motion controller for engraving machine. Through a lot of the drawing the users can learn
quickly how to use this motion controller.
1.2 Products specification

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 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 cathode,
inside of the device, there is GND 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.![](https://ae01.alicdn.com/kf/S27b5c25c305449c3b7f0274ee7fc95faw.png)

1 Ethernet port
As Figure 2-2 showed,No.1 terminal block is Ethernet port, you can connect with DM800
handle through this interface.
2 Stepper motor port
As Figure 2-2 showed,No.2/3/4/5/6 port is stepper motor port, which is define as
X/Y/Z/A/B. Each axis is define as PLUS+/PLUS-/DIR+/DIR-,. They are
pluse+/pluse-/direction+/direction-. The connection method with the stepper motor driver see as
Figure 2-3.

3 Spindle port
As Figure 2-2 showed,No.6 port is Spindle port. The interface definition is
VSO/GND/OT1/OT2 from left to right. Where VSO is the 0-10V analog output, OT1/OT2
digital drive signal output, spindle control output interface and spindle inverter connection
diagram figure 2-11. VSO/GND/OT1/OT2 are respectively connected with the inverter
AIN1/COM/X1/X2, where AIN1 is the input speed signal, COM converter X1 and X2 are the
common end configured to forward and reverse.

4.Output port
As Figure 2-2 showed,No.8 switch is Output port, The interface is an open-ground
interface. Definition of PORT 8 see as Table 2-1. The internal structure refers to figure 2-8,
which can be absorbed not more than 50mA current.Output port definition![](https://ae01.alicdn.com/kf/S54e95df6aafa44b4b67909d98b416a62o.png)

5 Main power supply port
As the Figure 2-2 show, The marked No. 10 and 11 port is power supply port for system
and IO. The access voltage range is 24VDC, and the power is not less than 20W. The positive
and negative connection of the power supply see as the silk printing, See as Figure 2-2, left is
GND, and right is "+"
6 Limit/Home input port
As the Figure 2-2 showed, Marked No. 9/12/13 position is the limited /home input port.
they are the optical isolated Input interface. Definition of Port9 see as Table 2-2. As shown in
Figure 2-2 shell silk print, and definition is
GND/INP1/INP2/GND/INP3/INP4/INP5/INP6/INP7/INP8/12V from left to right.
structure reference figure 2-3. The interface is a common negative interface, which can be
connected with a micro switch, a 2 line proximity switch or a NPN type 3 line proximity switch.
The interface is isolated by the optocoupler, and the internal structure diagram is referred to
figure 2-4. Estop, micro switch, 2 line proximity switch connection method reference figure 2-5.![](https://ae01.alicdn.com/kf/Se8909be3bfae460eb782c4104f30d157c.png)
