When you first open the ESA S840 parameter reference, you’ll see several key sections:<\/p>\n\n\n\n
- \n
- Bending step information<\/strong> (step number, target angles)<\/li>\n\n\n\n
- Axis positions<\/strong> (Y1, Y2, YB, X1, R1)<\/li>\n\n\n\n
- Correction values<\/strong><\/li>\n\n\n\n
- General data<\/strong> (material, thickness, tooling)<\/li>\n\n\n\n
- Work information<\/strong> (speed, force, timing)<\/li>\n<\/ul>\n\n\n\n
Pro tip:<\/strong> Take a few minutes to familiarize yourself with the layout before making any changes. This will save you time when you need to adjust parameters quickly during production.<\/p>\n\n\n\n
How to Configure Bending Parameters in ESA S840<\/h2>\n\n\n\n
The bending parameters section of the ESA S840 parameter reference determines how each bend is executed. Proper configuration here is the key to accurate, repeatable bends.<\/p>\n\n\n\n
Step 1: Choose the Correct Bending Method<\/h3>\n\n\n\n
The ESA S840 parameter reference supports five standard bending methods. Select the one that matches your application:<\/p>\n\n\n\n
Bending Method<\/th> Best Used For<\/th><\/tr><\/thead> Free bending<\/td> General purpose, most common<\/td><\/tr> Bumping<\/td> Large radii or multi-step bends<\/td><\/tr> Flat bending<\/td> Thin materials, precise angles<\/td><\/tr> Relative programming of X<\/td> Complex sequences with relative positioning<\/td><\/tr> Bottom bending<\/td> Thick materials, high tonnage<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n Example:<\/strong> For a standard 90\u00b0 bend in 2mm mild steel, select Free bending<\/strong>. The system will automatically calculate the required Y-axis depth.<\/p>\n\n\n\n
Step 2: Set the Bending Angle<\/h3>\n\n\n\n
The angle<\/strong> parameter defines the required product angle. Within the ESA S840 parameter reference, this value determines how deep the slider descends to squeeze the sheet metal into the die.<\/p>\n\n\n\n
How to set it:<\/strong><\/p>\n\n\n\n
- \n
- Navigate to the Angle field<\/li>\n\n\n\n
- Enter your target angle (e.g., 90\u00b0)<\/li>\n\n\n\n
- Press [ENTER] to confirm<\/li>\n<\/ul>\n\n\n\n
The system will then calculate the corresponding Y-axis position.<\/p>\n\n\n\n
Step 3: Configure X1 and R1 Positions<\/h3>\n\n\n\n
The X1 and R1<\/strong> parameters control the backgauge positions. In the ESA S840 parameter reference, these values determine where the material is positioned before each bend.<\/p>\n\n\n\n
Step-by-step:<\/strong><\/p>\n\n\n\n
- \n
- Locate the X1 field<\/li>\n\n\n\n
- Enter the distance from the backgauge to the bend line<\/li>\n\n\n\n
- If you have an R-axis (vertical backgauge), set the R1 value as well<\/li>\n<\/ol>\n\n\n\n
Step 4: Set Auxiliary Refund Value<\/h3>\n\n\n\n
The auxiliary refund value<\/strong> is the retreat distance of the selected axis during bending. When the slider clamps the plate, the “finger retreat” function activates, moving backgauge fingers away to prevent collision.<\/p>\n\n\n\n
Practical tip:<\/strong> Start with a small refund value (e.g., 5mm) and increase only if you see interference. Too much retreat can misalign the next bend.<\/p>\n\n\n\n
How to Enter Sheet Information and Product Processing Data<\/h2>\n\n\n\n
The ESA S840 parameter reference includes essential sheet information that affects production tracking.<\/p>\n\n\n\n
Completed Quantity and Number to be Processed<\/strong><\/p>\n\n\n\n
- \n
- Completed quantity:<\/strong> Automatically increments as parts are finished<\/li>\n\n\n\n
- Number to be processed:<\/strong> Enter the total parts needed for the job<\/li>\n<\/ul>\n\n\n\n
Why this matters:<\/strong> The system can stop automatically after reaching the target quantity, preventing overproduction.<\/p>\n\n\n\n
Measurement Method<\/strong><\/p>\n\n\n\n
Choose from three options in the ESA S840 parameter reference:<\/p>\n\n\n\n
- \n
- External size:<\/strong> Measures the outside dimension of the part<\/li>\n\n\n\n
- Internal size:<\/strong> Measures the inside dimension<\/li>\n\n\n\n
- Neutral layer:<\/strong> Measures based on the neutral bending axis<\/li>\n<\/ul>\n\n\n\n
When to use which:<\/strong> For most standard parts, external size measurement is sufficient. Use neutral layer for springback-sensitive materials.<\/p>\n\n\n\n
Unfolding Length<\/strong><\/p>\n\n\n\n
This is the actual required length of the product before bending. The ESA S840 parameter reference uses this value to verify that your blank size matches the program requirements.<\/p>\n\n\n\n
How to Set Basic Data for Bending<\/h2>\n\n\n\n
The basic data section is critical. Incorrect values here will affect every bend in your program.<\/p>\n\n\n\n
Step 1: Enter Plate Width and Thickness<\/strong><\/p>\n\n\n\n
- \n
- Plate width:<\/strong> The Z-axis width of the sheet metal<\/li>\n\n\n\n
- Plate thickness:<\/strong> The material thickness<\/li>\n<\/ul>\n\n\n\n
Common mistake:<\/strong> Forgetting to update thickness when changing materials. Always verify both values before starting a new job.<\/p>\n\n\n\n
Step 2: Select Material Type<\/strong><\/p>\n\n\n\n
Within the ESA S840 parameter reference, choose the correct material from the list (e.g., stainless steel, mild steel, aluminum). Different materials have different springback characteristics.<\/p>\n\n\n\n
Step 3: Choose Punch and Die<\/strong><\/p>\n\n\n\n
To select a punch:<\/p>\n\n\n\n
- \n
- Click on the Punch field<\/li>\n\n\n\n
- Click “Change Tool Selection”<\/li>\n\n\n\n
- Browse the punch list and select the desired tool<\/li>\n\n\n\n
- A schematic diagram appears on the right for visual confirmation<\/li>\n<\/ol>\n\n\n\n
To select a die:<\/p>\n\n\n\n
- \n
- Click on the Die field<\/li>\n\n\n\n
- Click “Change Tool Selection”<\/li>\n\n\n\n
- Select the appropriate die<\/li>\n\n\n\n
- Verify the schematic diagram<\/li>\n<\/ol>\n\n\n\n
Step 4: Select Slot Number and Tool Position<\/strong><\/p>\n\n\n\n
- \n
- Slot number:<\/strong> If your die has multiple V-slots, choose the correct one<\/li>\n\n\n\n
- Tool position:<\/strong> Select which station on the machine holds the tool (for Z-axis positioning)<\/li>\n<\/ul>\n\n\n\n
Pro tip:<\/strong> Always verify the tool position number matches the actual physical station where your tool is installed.<\/p>\n\n\n\n
How to Adjust Work Information Parameters<\/h2>\n\n\n\n
The work information section of the ESA S840 parameter reference controls machine motion and timing.<\/p>\n\n\n\n
- \n
- Tool position:<\/strong> Select which station on the machine holds the tool (for Z-axis positioning)<\/li>\n<\/ul>\n\n\n\n
- Slot number:<\/strong> If your die has multiple V-slots, choose the correct one<\/li>\n\n\n\n
- Plate thickness:<\/strong> The material thickness<\/li>\n<\/ul>\n\n\n\n
- Internal size:<\/strong> Measures the inside dimension<\/li>\n\n\n\n
- Number to be processed:<\/strong> Enter the total parts needed for the job<\/li>\n<\/ul>\n\n\n\n
- Completed quantity:<\/strong> Automatically increments as parts are finished<\/li>\n\n\n\n
