Precautions

1. After the container is unpacked, please check the system for any damage and verify if the contents in

the container are physically in conformance with the packing list.

2. This user's manual is applicable to Model SH-2012AH-QG CNC System for Cuttingmanufactured by

Microstep Control Technology Co., Ltd.

3. Please verify the conformance of local mains voltage. Be sure to use an AC220V isolation

transformer between the power supply network and the system to guarantee personal safety and

operating reliability.

4. The required ambient temperature for the CNC is ranged from 0

℃

to +40

℃

and the relative humidity

is from 0 to 85%.

Special protection is required in case of operating in a high temperature, high humidity or corrosive

gas environment.

5. Make sure the CNC is correctly wired and securely grounded.

6. Never try to hot plug/unplug any cable on the rear panel of the CNC, for the damage incurred thereby

is beyond our quality warranty.

7. No cable from the output port of the rear panel should be shorted with any power cable; otherwise,

the CNC might be burned.

8. Working in a very dusty environment, the whole system should be provided with dust protection in

addition to regular dust cleaning.

9. Trained operator should be specially assigned for the CNC.

10. The internal AC/DC power supply dedicated for the CNC should never share with any other electric

appliance.

11. The graphic programming software installed in the system is a beta version asking for advices,

which is subject to improvement in service and not taken as a requisite function and item for

acceptance. Please advise us timely in case of any debug in your use.

12. Please contact the manufacturer in case of any problem. Never disassemble, assemble or modify the

system the system without prior authorization and qualification.

13. Be sure to maintain the system and the cutting machine properly--routine maintenance and check

per shift, secondary maintenance per month and primary maintenance half a year.

14. Set the parameters in strict accordance with this user's manual or the supplemental instructions

given at placing order. The CNC might poorly function or even be damaged if the parameters are set

beyond the range.

15. The LCD screen is fragile and proper care is necessary in the process of operation.

16. The technical specifications are subject to change without prior notice.

17. Attention

Attention

Attention ：

The provided USB port is very small in power output, only good for USB disk and not

recommended for any other USB device to prevent damage.

18. The system power must be cut off when alternating the internal keyboard and an extended keyboard.

3.2.7.2 Example

Example

The system is able to identify and calculate the rotation angle by measuring the origin point and the end point

of an edge of steel plate(a straight line). The procedure is as follows:

1) Determine the datum line. Take one borderline of steel plate as baseline and move the cutting torch to the

origin point of this baseline. Press [F2] to set the beginning point of measurement.

2) Control the cutting torch and let it move along the baseline to the end point. The larger distance between

the beginning point and the end point, the more accurate of the measurement. Aim the cutting torch at the

baseline and press [F3] to set the end point of measurement.

3) At this moment, the rotation angle of the datum line is calculated. After the rotate function is fulfiled, the

rotation angle will appear in the OPERATE field, as shown in Fig. 3.2 below.

edge, the usual practice is to pinpoint an appropriate position in the exterior of workpiece for piercing and

then cut the workpiece back to the starting point along a straight line before continue normal machining

without stop.

3) In case of transitional cutting, too many workpiece or large size of workpiece, it might be necessary to

direction key is pressed again. If two axial movements are required, let one axial movement start first and then

press the direction key for the other axial movement. Two axial movement will go on simultaneously. In this

case, the axial movement of cutting torch will stop if the corresponding direction key is pressed while the other

axial movement will go on until the corresponding direction key is pressed too. [PAUSE] key will stop the

Since cutter compensation is made automatically, there must be G00 Quick Move command before G41 or G42

a G00 command is necessary to adjust the position back.

Principle

Generally, mechanical switch is used for travel limit/start/pause. To shield the system from interference,

normally-closed contact is usually used for mechanical switch, which is connected with the way described

below.

Notes:

�The logic for emergency stop, pause and travel limit of the system is the same, i.e., they are all connected

to normally-opened contact(NO contact) or normally-closed contact(NC contact).

�

After powered on, the system will automatically check the level of activation bit as control reference.

�Therefore, if external start switch is not connected, the corresponding activation bit should be connected to

24V ground (similar to connection to NC contact) or nothing(similar to connection to NO contact).

Notes:

1. The start key, pause key, emergency stop key and backspace key are required to connect to the

input/output port through normally-closed contacts. These four keys are enabled at system booting and

not affected by the possibility if the external manual control box is enabled or not.

2. X+, X-, Y+ and

Y-

piercing keys are connected to the system auxiliary connector (DB15), which are

required all to use normally-closed contact or normally-opened contact. It means the logic of the 5

ports must be the same, all NO contact or all NC contact. The availability of these 5 external control

keys depends on the option of external manual control box for height controller in parameter setting.

When the option is enabled, they will function.
