Figure 1-1 CNC System Interface

1、Alarm Show

This area displays alarm status of the system .Alarm status are divided into the

following:

1

1) System Reset: After press Overtravel released key when release Emergency Stop

Switch or over travel, system needs certain time to reset. During this period,

system can not be operated, and the Alarm Display area shows “Reset”.

2) Over Travel: When the workbench stroke travel switch, system turns up overtravel

alarm and the Alarm Display area shows “Reset”.

3) Emergency Stop: When press E-Stop button down, system turns up emergency stop

alarm and the Alarm Display area shows “E-Stop”.

4) System Alarm: When turns up other alarms except the mentioned above, the Alarm

Display area shows “System-Alarm”.

When the alarms above occur at the same time, the priority displayed in the Alarm

Display area is the following (the left has high priority, that means it will be shown in

front of others when alarm appear):

Reset

Overtravel

E-Stop

System-Alarm

2、Working and Running Status

There are three kinds of operation modes: Automatic,Manual and Handwheel.

Every mode has stop, run and pause status by machine tool’s running status. The

Working and Running Status area shows in real-time what is the current operation mode

and running state. For example, “Manu/Stop”means the current operation mode is

“Manual”, and machine tool’s running status is “Stop”(halted state).

3、Main Window Show

The Main Window displays tool’s position in workpiece coordinate system or machine

coordinate system, that is workpiece coordinate or machine coordinate. The coordinate

system which displays can be changed by setting parameter P0017.

4、First Side Window Show

First Side Window displays tool’s position in machine coordinate system or

workpiece coordinate system, that is machine coordinate or workpiece coordinate.The

coordinate system which displays can be changed by setting parameter P0017.

5、Second Side Window Show

Second Side Window can display workpiece coordinate zero, synchronization error

2 Manual Operation

Manual operations include two kinds of operation modes：reference point return mode

and manual feed mode. The first mode is used to set up the machine coordinate system

with all axes returned to the origin position; the second mode is used to move all

coordinate axis manually. The two modes can be switched to each other by pressing

<REF> key. The first mode is active when the indicator light of < REF > key is on. The

second mode is active when the light is off.

2.1 Manual Reference Point Return

2.1.1 Process of Reference Point Return and Speed

Setting

Figure 2-1 Process of Reference Point Return map

The process of returning reference point includes three steps(as shown above):

1) Start from point A, move to point B. Then it will slow down from point B when

detecting the signal from the pressed reference point block to point C. At the first

step, which belong to high speed position period, you can set higher moving speed.

The speed of returning reference point is determined by parameters as follows:

P3021: X-axis high speed returning home speed(mm/min)

P3022: Y-axis high speed returning home speed(mm/min)

P3023: Z-axis high speed returning home speed(mm/min)

Figure 2-2 Tool’s Fixed Coordinate System

The method of opening up the feed function of tool’s fixed coordinate system:

<Manual/Increment> →[\] → [Tool Axis Feed] → [Open]

The method of closing up the feed function of tool’s fixed coordinate system:

< Manual/Increment> →[\] → [Tool Axis Feed] → [Close]

After opening up the feed function, when move the Z-axis by handwheel, jog or

increment mode, the tool will move along the Z-axis’s direction in the tool’s fixed

coordinate system(tool aixs’s direction ); Similarly, when move the X-axis,Y-axis by

handwheel, jog or increment mode, the tool will move along the direction of

X-axis,Y-axis in the tool’s fixed coordinate system.

Note:

1、 It’s necessary to set the machine’s structure type correctly by the parameter of

P400 and P401, or the feed function can not be implement accurately；

2、 Only the machine’s structure type which system support can be implemented the

feed function, or the correctness of machine tool’s motion cannot be guaranteed.

3.1 Loading a Machining Program

Figure 3-1 Program Selection Screen

Sequence of entering the program loading screen:

<AUTO> → [\] → [PROG] → [LDPG].

It is shown in the figure 3-1 above.

The system menu which is workable in program selection screen includes:

[LOAD]: Load the selected program to the memory.

[SPGM]: Show a list of program files from the system’s internal storage.

[UPGM]: Show a list of program files from the external storage.

[NPGM]: Show a list of program files from the NC port by network mapping.

[EPGM]: Show a list of extended program files.

[NSRT]: Sort a list of program files by name;

[TSRT]: Sort a list of program files by modification time;

[PRET]: Load nothing and return to previous menu.

3.1.1 Program Preview

In the program selection screen, after the cursor select a program, you can preview

the selected program in the program preview screen on the right, as figure 3-1shown.

3.1.2 Loading a System Program

Sequence of loading a system program is as follows:

1) Switch to the program selection screen;

2) Show a list of system program files. The LCD screen shows a list of system program

conventionally when you enter into the program selection screen at the first time. If

it doesn’t show the list after some operations, you need press [SPGM] key to switch

to it. The list window title bar shows the storage of the current indicated program. It

shows “System Program” means that the displaying program is from the system’s

internal storage, as figure 3-2 shown;

3) Use the [↑]、[↓] or [PageUp]、[PageDown] keys to select a program which need

loading, or input the filename into the window of program filename directly.

4) Press the [LOAD] key to load the selected program to memory.

Figure 3-2 A list of system program files

If the parameter P0003 value is 1, CNC system will check the syntax of the loaded

15

program after loading (as figure 3-3 shown). If you are sure that the program has no

syntax error, you can press the [ESC] key to cancel syntax checking.

Figure 3-1 Program Syntax Checking

the content of the loaded program is shown in the code window, as figure 3-4 shown.

Use the [↑]、[↓] or [PageUp]、[PageDown] keys to read the program before automatic

operation.

Figure 3-2 Code Display Window

3.1.3 Loading a External Program

Sequence of loading an external program is as follows:

1) Switch to the program selection screen;

2) Show a list of external program files. The LCD screen shows a list of system

program conventionally when you enter into the program selection screen at the

first time. Press the [UPGM] key to switch the screen to it. The list window title

bar shows the storage of the current indicated program. It shows “External

Program” means that the displaying program is from the external storage device,

as figure 3-5 shown;

16

3) Use the [↑]、[↓] or [PageUp]、[PageDown] keys to select a program which need

loading, or input the filename into the window of program filename directly.

4) Press the [LOAD] key to load the selected external program to memory.

Figure 3-5 A list of external program files

If there are no external storage devices and you press the [UPGM] key, the title bar

will show a warning prompt, as figure 3-6 shown. Press any key in the panel can remove

this prompt .

17

Figure 3-6 No External Storage Devices

3.1.4 Loading a Network Program

The operation of loading a network program is the same as loading an external

program. If the CNC syatem has been configured the network-mapping device, the

program in the network-mapping device can be shown after you select the network

program, as figure 3-7 shown.

18

Figure 3-3 Network Program Loading Interface

3.1.5 Loading an Extended Program

In general, the extended program key is gray, which is not operating. The key can be

recovered operation by setting the parameter P0002, as figure 3-8 shown.

19

Figure 3-4 Extended Program Loading Interface

The extended program can be loaded into memory to read、edit、modify、save, but

it is not recommended to operate the extended program, so you’d better set 1 for the

parameter P0002 to hide and protect it.

3.1.6 The Syntax Checking Setting

Generally, CNC system will check the syntax of the loaded program after loading.

If there are some mistakes in syntax checking, the loaded program can’t be executed.

The function of syntax checking is set by the parameter P0003:

P0003=0: Don’t check the syntax when loading program

P0003=1: Check the syntax when loading program

You’d better use this function in practice to ensure the loaded program works

normally.

20

Firstly, press the <FDHD> key (or SBL stop)to make the execution pause, then

press the [PROG] key→[STOP] key in turn and then it will pop up a dialog, as figure

3-9 shown. At the time, pressing the [ENTER] key will terminate the execution or

pressing the [ESC] key will cancel the stop operation. CNC system’s state is the same

as that before running (the modal codes of the program have been stored), Then the

Working and Running Status bar will show “AUTO/STOP”.

Figure 3-9 A dialog of terminating a running program

2）Method with pressing the [RNGN] key

This method is similar to the prior method. Both of them can exit from the current

processing state. The difference is: In the first method, the current line remains the

machining line when exit, but in the second method, the current line automatically

returns to the first line of the program.

3.3 Verifying a Program

When write a new program, you can use the program verification function to test the

working path is right or not.

During the process of verifying a program, the M codes except M00，M01，M06，

M30，M98，M99，M128，M129 and all the S, T codes aren’t effective.

Sequence of verifying a program is as follows:

1) Switch to the mode of verifying a program. Press these keys as follows in turn:

<AUTO> →[\] → [PROG] → [TEST];

2) Press the <CYCL> key to start the program verification.

The mode of verifying a program will be closed in these situations as follows:

1) When verifying a program, Press<FDHD>, and then select <STOP> or <RNGN>,

22

the system will automatically close the program verification mode;

2) When verifying a program, Press<FDHD>key and then quit from the automatic

mode, the system will automatically close the program verification mode;

When the program verification mode is closed, it returns to the normal running mode.

Figure 3-10 Verifying a program

3.4 Program Breakpoint

During the process of machining, For some reason you may turn off the machine

halfway. The breakpoint means that the segment of the program executing and the

machine tool’s position and status messages when turn off. So the breakpoint saving and

recovering fuction is important when resume running from the program breakpoint.
