In auto mode, the program runs automatically
 MDI operation mode
In MDI mode, input the parameters, and insert and execute instruction segment.
 Mechanical reset operation mode
In mechanical reset mode, perform the mechanical reset operation for X axis and Z axis
respectively
 Handwheel/single step operation mode
In single step/handwheel feeding mode, the system moves in selected increment
 Manual operation mode
In manual mode, perform the operations such as manual feeding, manual speed, feeding
rate regulation, quick rate regulation, main axis start/stop, cooling liquid switch, lubricant
switch and manual knife switch.
 Program reset operation mode
In program reset mode, perform the program reset operation for X axis and Z axis
respectively.
1.5. Display interface
This system contains six interfaces, including position and program. Each interface contains several
pages. Press the display menu key to switch interfaces, and press the Up/Down key to turn pages.
The interfaces (pages) are independent to the operation modes.

1.5.1 POSITION INTERFACE
Press the position key to enter the position interface, which consists of absolute, relative,
comprehensive and position/program pages. You can press the Up/Down key to
view.
Absolute coordinates
The X coordinate and Z coordinate are the absolute position of the knife in current work piece
coordinates system, which is specified by G50.
Fig. 1-3-1
Programming speed: the speed specified by F code in the program (unit: mm/min).
Actual speed: the actual processing speed (unit: mm/min) after the magnification has been adjusted
in the actual processing.
Feeding magnification: the current feeding magnification
Quick magnification: the current quick magnification
G function code: current valid G code processing pieces in Group 01 and 03: when the program has
executed M30, the processing pieces are increased by 1.
Cutting time: the cumulative time when the program and MDI are running; the time format is: Hour:
Minute: Second. The cutting time is 0 when the system is electrified.
T: current tool number
S: current main axis rotation speed
Note: The main axis encoder is necessary to display the actual rotation of the main axis.
Relative coordinates
The U coordinate and W coordinate, which are 0 when the system is electrified, are the
relative coordinates of current position relative to the reference point. In manual mode, press the
letter key or , and the U or W flashes in the page; press the Cancel key to
reset the U or W coordinate.

Comprehensive coordinates
In comprehensive position page, relative coordinates, absolute coordinates, machine tool
coordinates and remaining movement are displayed at the same time. The value of machine tool
coordinates is the coordinates of current position in machine tool coordinates, which is created
through mechanical reset. The remaining movement is the difference between the target
coordinates of program section or MDI instruction and the current absolute coordinates.
The page follows:
