Precautions:
Precautions can be divided into caution and warning according to the degree of possible loss or injury in
case of negligence or omission of precautions stipulated in this manual.
CAUTION
: General info, mainly for informing, such as supplementary instructions and
conditions to enable a function. In case of negligence or omission of this kind of precautions, you may
not activate a function. Note that in some circumstances, negligence or omission of even this kind of
precautions could cause physical injury or machine damage.
WARNING
: Warning info requiring special attention. In case of negligence or omission of
this kind of precautions, you may suffer physical injury, or even death, machine damage or other losses.
WARNING
1) Precautions Related to Storage and Transportation
The products should be transported properly in terms of the weight;
An excess of specified quantity of stacking products is prohibited;
Climbing, standing or placing heavy loads on the products is prohibited;
Dragging or carrying the products via cables or devices connected to them is prohibited;

Preface「III」
WARNING
2) Precautions Related to Installation
Only when this equipment installed in the qualified electricity cabinet can it be used. The
construction of the cabinet must reach IP54 grade of protection;
Paste sealing strips on the joint of the cabinet to seal all the cracks;
Cable entry should be sealed while easy-to-open on the spot;
A fan or heat exchanger should be adopted for the heat dissipation and air convection of the
cabinet;
If a fan is adopted, air strainer is a must in air inlet or air outlet;
Dust or cutting fluids may have access to the CNC device via the tiny cracks and tuyere.
Therefore it is necessary to pay attention to the surroundings and air flow direction of the air
vent to make sure that the outflow gas is towards pollution source;
100 mm space should be preserved between the back of the CNC device and the cabinet wall
for plugging cable connected with the device and the ventilation & heat dissipation in the
cabinet;
Space between this device and other equipment should also be preserved according to the
requirements;
The product should be installed firmly and without vibration. During installing, casting,
knocking, striking, or loading on the product is forbidden;
To reduce electromagnetic interference, power-supply components used should be above AC
or DC 50V and the space between cable and CNC device should be preserved above 100mm;
It will be better if CNC device is installed at a position facilitating debugging and maintenance.
3) Precautions Related to Wiring
Only qualified people are allowed to participate in the wiring and checking;
The CNC device should be grounded reliably and grounding resistance should be less than 4
ohm. Neutral line is absolutely not allowed to replace earth wire. Otherwise, it may result in
malfunction of the device due to the interference;
Wiring should be firm and steady, or misoperation may occur;
Voltage values and positive & negative polarity of any connection plug should be in accordance
with specifications set forth in the manual, or it may result in breakdowns such as short circuit
and permanent damage to the device;
To guard against electric shock or CNC device damage, fingers should keep dry before

Specialized Concentrated Focused
「IV」Preface
WARNING
plugging or touching switch;
The connecting wire should not be damaged and squeezed, or the leakage or short circuit may
occur;
It is prohibited to plug or open the chassis of CNC device when power on.
4) Precautions Related to Running & Debugging
Parameters setting should be checked before running, since wrong setting may lead to
accidental movements;
Modification to parameters should be within the allowable range, or such breakdowns as
unsteady running and machine damage will occur.
5) Precautions in Use
Before power-on, please make sure that the switch is on blackout to avoid occasional start-up;
Please check the electromagnetic compatibility during electrical design in order to avoid or
reduce electromagnetic interference to the CNC device. A low pass filter should be employed
to reduce electromagnetic interference if there are other electrical devices nearby;
It is not allowed to frequently power on and power off. It is recommended to power up the
machine again at least one (1) minute later after power failure or blackout.
CAUTION
1) Precautions Related to Product and Manual
Matters related to restrictions and functions available stipulated in the manuals issued by the
machine manufacturer are prior to those in this manual;
This manual assumes all the optional functions are available, which you must confirm through
manuals issued by the machine manufacturer;
Please refer to manuals issued by the machine manufacturer for the instructions of machine
tools;
Functions, and software interfaces vary with the system and the version of software. Before
using the system, you must confirm the specifications.

Summarization「1」
1. Summarization
Independently-developed by Weihong and based on embedded industrial control platform, the four axes
integrated CNC system NK105G2F/G3F provides a whole set of solutions to engraving machines.
The integrated CNC system NK105G2F/G3F is composed of a host system and an operation panel.Also
called control box, the host system integrates system control card, terminal board and other parts, and
connects with the operation panel via a 15-pin extension cable.
The up and down ends at the back of the control box are used to inlay terminals while the left side
includes an USB interface and a DB15 interface. The DB15 interface is for connection with the operation
panel, while the USB interface for external connection with USB equipment (e.g. USB flash drive).
Also called handheld box, the concise and portable operation panel is connected with the host system
via a 15-pin extension cable, so it can work independently without the distribution box to facilitate
machine tool control. And its moving distance is only restricted by the length of extension cable.
1.1. Basic Configuration
NK105G2F/G3F system is composed by handheld box and control box. Refer to following table for
details.
