4.2 Human-computer interface
4.2.1 Preface
This instruction is only about the human-computer interface operation instruction. Reading this manual should
be based on a certain understanding of the working principle, structure and related cutting process of the machine
tool, so before this should carefully read the random "machine tool manual", combined with the relevant chapters to
understand this description. This instruction has not done, please forgive more, if has not understood please
consult with the manufacturer service personnel .

Boot into the manufacturer's promotional
screen, the lower left corner is the buttong

interface. In the lower right corner is the
button for Chinese users to enter the
Chinese interface.

※To enable manual function, you must first switch the external button to manual shift, otherwise other buttons will
be invalid
The upper part of the screen is the functional area Shared by all interfaces. The following description is
applicable to the functional interface. It will not be repeated in the future.
Clock display: display time, date and other information. If there is any deviation from the local actual clock, the
clock information can be calibrated in the human-machine setting interface.
Current system status: it shows whether the current system is in manual mode 、auto mode、back original
mode, so that the operator can be clear at a glance.
Cutting mode:Display whether the current machining is constant speed cutting or variable
speed cutting.
Communication connection: it is used to indicate whether the communication connection between the human-
computer interface and the PLC is normal. The indicator light flashes when it is normal. Otherwise, the
communication connection line with PLC should be checked.

4、Instruction Manual
17
System status prompt bar: it indicates whether the current system is normal or abnormal.
Saw
blade linear speed: the machine tool is equipped with a saw wheel rotation induction device.
When the main machine is running, the system will detect the state of the high-speed signal
device.
For the operator to determine whether the speed of the saw blade meets the requirements
of the production cutting process.
Note: this function can only be used normally when the parameter "setting diameter of saw
wheel" is set in the "advanced parameters" interface.
Cutting speed:Display the current working speed value.
Current sawing force:Display the current sawing force.
Return position of material tongs:The machine is equipped a magnetic grid linear displacement
sensor,where the current position of the material table can be dynamically displayed in real time when the material
table moves back and forth.This function enables the operator to observe the dimension positioning of the material
rack at any time,and is conducive to the rapid troubleshooting of the feeding positioning fault of the machine.
This screen can complete the operation of machine all independent actions.
The work start is driven by motor, and other actions are all driven by hydraulic . Note that some actions has
their interlocks, limit protection and other functions, listed as follows:
1. Only when the main clamp solenoid valve works, "work start" can be self-locking operation, otherwise for inching
operation.
2.“work start", "main clamp clamping", "material clamp clamping", "rise" with self-locking function, other are inching.

4、Instruction Manual
18
3. "main clamp clamping t" and "main clamp loosen", "material clamp clamping" and "material clamp loosen", "fast down"
and "up", "feeding" and "return" are all interlocks.
4. When the work is started (cutting material), the "main clamp loosen" cannot be executed.
5. When the main clamp and the material clamp are both clamped, "feeding" and "returning"
cannot be executed.
6. When the saw frame reaches the lowest position, the lower limit switch action, the saw
frame will automatically turn into retractor.
7. When the frame reaches the upper limit switch position, the upper limit switch action, the
saw frame stops
Reset position: under manual mode, the
system allows the machine operator to manually reset the position of the current rack. Press "reset position" to
pop up the interface (as shown in the right picture), press "confirm" to reset, and press "close" to return.
