Introduction:
NCH02 is a CNC system without computer. Only need a U-disk within G-CODE file,
NCH02 can read the G file and run the G file.
Port Definition and connection：
1.USB interface
2. Main power interface
3. Input and output power
4. Input interface such as limit origin
5.MPG interface
6. Universal output interface
7. Spindle control output interface
8. Drive control interface
Features of Power Supply:
Built-in over voltage, over current, and short circuit protection
PWM design, make sure the stability and high efficiency of power supply.
Anti-jamming, passed EMC test, wave less than 20MV.
Constant voltage output, assume stable power supply for LED lightings to reach long lifetime
Performance parameters:
Read G-CODE from U-DISK;
Operation without computer;
8 ports photoelectric isolated input interface ；
5 ports photoelectric isolated output interface ；
1 port 0-10V spindle speed analog output interface(can change to PWM output) ；
can support 5 axis stepper systems,125KHz pulse output for every axis ；
ARM motion control chip ；
main device is 24VDC power supply input, current should higher than 1A
Support standard MPG and NVMPG;
3.5'' TFT screen;
19 user key;
Glossary:
When operate the NCH02, where will be a lot of English abbreviation, now we list all of
them for your kindly references:
FRO: Feeding adjust: During the operating process, the F value already set, and need to
adjust the current feeding speed, then we can adjust FRO value to realize it.
SRO: Spindle speed adjust: During the operating process, the S value already set, and need
to adjust the current spindle speed, then we can adjust SRO value to realize it :
Current Speed S#=setting S*SRO.
SRJ: speed adjust manually
During the operating process,as the manual speed already set,and we need to adjust the
current speed,and impossible to fix the value during it is working,then we can revise the SRJ
value to realize it.
Current manual speed FS#=Setting manual speed*SRJ.
F:Feedingspeed,the unit is mm/min.For example F=200,means every minute feeding
2000mm.
S: Spindle Speed. Unit is rad/min.For example S=20000,means 20000 revolution/Minute.

Ready:ReadyMode.In the mode we can do any operation,include processing or values
modification or starting 2nd mode.
Reset: Reset mode.In this mode,it should stop every operation.
“Step”:Manual Step Mode. Every axis candonduct the manual step operation at this mode.
MPG: MPG mode.Every axis can conduct the MPG operation at this mode.
Products Appearance and size：
The Hand control system NCH02 appearance as the Figure 1-1 show: The host system
NCD02 appearance as the Figure1-2.
The Hand control system NCH02 overall size is 168mm*108mm*30mm ；
The host system DM100 overall size is 165mm*105mm*20mm
Equipment power supply:
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. The chassis is built with 220V to 48V DC supply to the DC brushless spindle and 4 step
motor driver.
