Interface Page Structure

Grasping the page structure of the ESTUN E300 Programming interface is the key to smooth navigation and operation. After powering on the device and waiting for the system to load, the screen will automatically display the default Single-Step page. The entire interface is divided into five core sections, each with a specific functional role, and familiarizing yourself with each part is essential for basic operation.

Title Bar

This section is visible on every interface page, and its display content is fixed from left to right: Page Name, System Status, and Operation Mode.

• Page Name: Shows the name of the current operating page, such as SingleStep, Multi, or Program.

• System Status: Displays the real-time working status of the system, with a total of six different status options for the ESTUN E300.

• Operation Mode: Indicates the current operational mode of the device, with three distinct modes available for selection.

Axis Position Display

This area shows the real-time position values of the machine’s axes, a critical component for achieving precise bending control. The standard ESTUN E300 device comes with default X-axis and Y-axis control functions; for access to more advanced axis control features, it is recommended to contact the official ESTUN technical support team.

Parameters Area

This section displays the parameter information corresponding to the current operating page—each functional page has its own unique set of adjustable parameters, all clearly presented here for quick viewing and editing.

Information Section

In the ESTUN E300 interface, this part details every configurable parameter, including editable value ranges and current set values. The system time is also displayed on the right side of this section for easy reference during programming and operation.

Navigation Bar

The navigation bar corresponds to the F1 to F6 function keys on the operation panel, enabling one-click switching between the system’s main functional pages. For the specific function of each key and the corresponding page description, refer to Table 2-3 in the official ESTUN E300 user manual. Mastering the navigation bar is a basic skill that streamlines all subsequent programming operations.

Familiarity with the above page structure will let you proficiently navigate the ESTUN E300’s various functions and settings, laying a solid foundation for a smooth programming experience.

Single-Step Programming

Single-Step Programming is the default function page for the ESTUN E300 (displayed immediately after power-on) and is specially designed for quick bending operations that require only a single set of bending parameters. You can also manually enter this page by pressing the F1 function key on the operation panel. Table 2-4 in the user manual provides a detailed explanation of all adjustable parameters on this page, which is a useful reference for parameter editing.

Practical Programming Example

Let’s take the bending of a 120mm steel plate as a concrete example to detail the Single-Step Programming process.

 The core bending requirements are: X-axis position set to 60mm, bending angle of 90°, steel plate thickness of 7.5mm, and stock value of 50. We use angle-based programming, with the die ID set to 1. Based on practical operation experience, we also set auxiliary process parameters: holding time of 3 seconds, retracting delay of 2 seconds, and retract distance of 5mm.

The specific programming steps are as follows:

1. Navigate to the Die parameter and input the value 1;

2. Select the Material parameter and enter the value 1;

3. Find the Thickness parameter and input 7.5;

4. Set the Hold Time parameter to 3;

5. Enter 2 for the Retr. DLY (retracting delay) parameter;

6. Set the X-axis position parameter to 60;

7. Input 5 for the Retract distance parameter;

8. Select the Angle parameter and enter 90;

9. Set the Stock parameter to 50.

Before starting the operation, ensure the Count Mode on the Constant page is set to Cnt Down. Finally, press the START key on the operation panel—the servo axis will automatically complete position calibration, and the machine is ready for formal production once the calibration is finished.

Multi-Step Programming

Multi-Step Programming is used for complex bending processes that require multiple sets of different bending parameters and steps, and you can enter this functional page by pressing the F2 function key. 

All parameters on this page are detailed in Table 2-5 of the official user manual, which can be consulted during parameter setting and editing.

Practical Programming Example

We use the bending of an 180mm steel plate to demonstrate the Multi-Step Programming process. This bending task requires two separate steps: bending angles of 90° for both the 120mm and 30mm segments of the steel plate, with a plate thickness of 7.5mm and stock value of 50mm. We adopt angle-based programming, set the die ID to 1, and configure the same auxiliary process parameters as the single-step example: holding time 3s, retracting delay 2s, and retract distance 5mm (material type set to steel, value 1).

The specific programming steps are as follows:

1. Move the cursor to the Die parameter and input 1;

2. Set the Thickness parameter to 7.5;

3. Select the Material parameter and enter 1;

4. Input 50 for the Stock parameter;

5. Set the Retr. DLY parameter to 2;

6. Enter 3 for the Hold Time parameter;

7. For the first bending step (BN 1), set the Angle parameter to 90;

8. For BN 1, set the X-axis position parameter to 30;

9. For BN 1, input 5 for the Retract distance parameter;

10. Confirm all parameters of the first step by pressing the ENTER key;

11. A pop-up dialog box will prompt you to create a new bending step—click OK to confirm;

12. For the second bending step (BN 2), set the X-axis position parameter to 120;

13. For BN 2, set the Retract distance parameter to 5;

14. Press the START key on the operation panel to initiate the multi-step bending process.

After the above settings, the servo axis of the ESTUN E300 will automatically complete the position calibration for each bending step, and formal production can begin once the machine is ready.

Manual Axis Movement

Mastering manual axis movement is a fundamental skill for ESTUN E300 operation, as it is essential for equipment debugging and fine position adjustments of the servo axes. The servo axes are driven by servo motors, and their manual movement can be controlled via the arrow keys on the Manual page—this operation does not require starting the formal production process, making it ideal for pre-operation equipment commissioning.

You can enter the Manual page by pressing the F3 function key after powering on the device (the system displays the default page). The operation method for manual movement is simple:

• Press the UP and DOWN arrow keys to select the servo axis you need to adjust;

• Press the LEFT and RIGHT arrow keys to set the movement direction of the selected axis.

Proficiency in this basic operation ensures precise pre-adjustment of the machine, laying the groundwork for accurate bending results.

Die Parameter Configuration

When using angle-based programming for bending processes, correct configuration of die parameters is a prerequisite for accurate bending. You can enter the Die parameter configuration page by pressing the F4 function key on the operation panel, and the parameter setting method is as follows:

1. Press the UP and DOWN arrow keys to select the die ID you need to configure;

2. Press the LEFT and RIGHT arrow keys to switch between different adjustable parameters of the selected die;

3. Enter the required parameter values using the numeric keys on the operation panel.

The technical parameters of the die are shown in Figure 2-7 of the user manual, with the core parameters defined as follows:

• H (Die Height): Used to calculate the bending depth of the machine;

• V (V-opening Length): The distance between the intersecting tangent lines of the die’s V-opening;

• α (Die Angle): The fixed angle of the die’s V-opening;

• R (V-opening Edge Radius): The fillet radius of the die’s V-opening edges;

• S (Safety Distance): A critical parameter for machines equipped with an R-axis, designed to prevent collisions between the operating handle and the die. The minimum safety distance is calculated automatically by the system based on die dimensions using the formula: S = FS ＋ V／2 (FS = the flat section on the back side of the V-grove; V = the die’s opening value).

Bending Correction Methods

Achieving precise bending results with the ESTUN E300 relies on mastering bending correction techniques. Before formal production processing, it is essential to complete machine commissioning: program a simple bending process on the Single-Step page and run one full bending cycle, then measure the actual bending angle, bending depth, and back gauge distance of the workpiece. Compare these actual values with the programmed set values to determine whether correction adjustments are needed. The ESTUN E300 supports three core correction types: angle correction, Y-axis correction, and X-axis correction, each with a clear adjustment range and operation method.

Angle Correction

The adjustable range of the angle correction parameter (Corr. α) is -90 to 90. If the actual bending angle of the workpiece does not match the programmed display value, perform correction according to the deviation value: for example, if the programmed angle is 90° but the actual measured angle is 92°, set Corr. α to -2; if the actual measured angle is 88°, set Corr. α to 2 to compensate for the deviation.

Y-axis Correction

The Y-axis correction parameter (Corr. Y) has an adjustable range of -99.999 to 99.999, used for fine-tuning the bending depth. For depth-based programming, you can optimize the correction effect by repeatedly setting Corr. Y, accumulating practical operation experience, and measuring the bending depth change per degree of angle adjustment. This iterative adjustment process ensures the actual bending depth matches the design requirements.

X-axis Correction

X-axis correction (Corr. X) follows the same basic logic as angle correction, with an adjustable parameter range of -99.999 to 99.999 for precise back gauge position adjustment. For example, if the programmed X-axis position is 100.00mm but the actual measured position is 102.05mm, set Corr. X to -2.05; if the actual measured position is 98.05mm, set Corr. X to 1.95.

Note: The Single-Step Programming mode allows the machine to be stopped at any time during the bending process, and the X-axis programmed value can be modified directly—so Corr. X is generally not required for single-step operations. However, Multi-Step Programming involves multiple consecutive bending steps, and Corr. X can be independently assigned to each step for targeted position correction.
