1.1 Introduction
The E300 is a dedicated NC (numerical control) device for the Torsion Bending Machine, which
combines the expertise of ESTUN for many years and provides a complete economic solution for the
Torsion Bending Machine with the support of unique drive control technology.
The E300 device adopts the integral product structure, built-in high-performance A8 processor, and
configures 5.6 inch, 640 × 480 dot matrix, 18 full color display screen, and integrated IO ports, serial
ports and USB port.
The E300 device is designed to be operated via the buttons on the front panel.At the same time, the
pump switch and the emergency stop button are installed in the customized suspension cabinet to
meet the user's requirements, as shown in Figure 1-1.

1.2 Features
The E300 device inherits ESTUN classic mode of operation, through a simple and intuitive
parameter configuration interface to complete the bending machine control operation. Its friendly
interface, easy to use, practical function, and has the following features:
4 axes are supported, viz, X-axis, Y-axis, R-axis and C-axis.
Automatic calculation of the block position, according to the bending angle, material, thickness
and mold parameters.
The back gauge can be controlled in a high-accuracy since the servo systems control X-axis and
R-axis.
Optional hydraulic or mechanical to control the C-axis.
Program in absolute value or angle.
You can backup, restore, import and export the parameters, for commissioning the machine
easily.
Edit the program in one page, for improving the operating efficiency.
You can program the dwell time (holding time) andretracting delay by the device instead of the
time relay.
Interference or collision of the die can be avoided.
The opening distance can be adjusted, for improving the operating efficiency.
Automatically adjust the clamping point position.
You can view the status of inputs, outputs, valves and faults on the Monitor page at any time.
Automatically adjust the zero position of the R-axis.
Materials and die informations are programable.
Three of operation mode (Jog, Single, Continuous) for the jobs.
Language setting and unit setting.
IO ports can be allocated freely, and the device can detect them for avoid the repeat.
Bilateral positioning and unilateral positioning.
Slug clearance function.
Teaching or search the reference point.
The Axis, which is controlled by a servo system, can be manually moved.
Real-time memory the parameters, positions and programs against the unexpected accidents such
as interruption of power supply.

Example
We take the following process as an example to describe the programming.
Steel plate, length is 120mm 60mm
60mm
90°
Thickness is 7.5mm
×50 ×50
In this example, we can learn a set of the basic data: material is steel; X-axis is 60; bending-angle is
90; thickness is 7.5; stock is 50.
We decide to program the process by the given angle, and supposing the die ID is 1.
In addition, we can set some other necessary parameters according to our experience, such as
holding time is 3, retracting delay is 2, and retract distance is 5.
Follow the below procedure to perform the program.
1. Move the cursor on Die, and type 1.
Note: For details about the setting of the die, see the section 2.6 Die Settings.
2. Move the cursor on Material, and type 1.
3. Move the cursor on Thickness, and type 7.5.
4. Move the cursor on Hold Time, and type 3.
5. Move the cursor on Retr. DLY, and type 2.
6. Move the cursor on X-axis, and type 60.
7. Move the cursor on Retract, and type 5.
8. Move the cursor on Angle, and type 90.
9. Move the cursor on Stock, and type 50.
Note: please set the Count Mode to Cnt Down on the Constant page beforehand.
10. Press START key on the operation panel.
Now, the servo-axis can start to positioning. When the machine is ready, it can be produced.
