ESA S840 automatic mode is the go-to setting for high-efficiency production runs on your HARSLE prasa krawędziowa. Unlike semi-automatic mode, which requires operator confirmation after each bend, automatic mode executes all programmed bending steps continuously, dramatically reducing cycle time and increasing throughput. If you’re ready to move from first-part verification to full-scale production, this guide will show you how to smoothly start and safely operate ESA S840 automatic mode. Whether you’re running hundreds of identical parts or just want to streamline your workflow, you’ll learn how to set up, monitor, and optimize automatic bending with confidence.

How to Switch to Automatic Mode

Switching to ESA S840 automatic mode is straightforward. Click on the navigation bar icon to switch to automatic production mode. Once you are in automatic mode, simply press the przycisk start to run the product program. The machine will execute each bending step in sequence without requiring operator confirmation between bends.

How to Set Production Quantity

One of the most useful features of ESA S840 automatic mode is the ability to preset the number of parts you wish to produce.

Kliknij na “Set quantity” . In the pop-up dialog box, you can enter the required number of processed parts for the product. This is especially helpful for production runs where you need to produce a specific batch size.

When the quantity is completed, the system will display a message in the information bar at the top of the screen:
“PM004 product processing count completed” . If you need to continue producing more parts beyond the set quantity, simply press the start button again to continue.

How to Reset the Processed Count

If you need to start a new production run or reset the counter for any reason, ESA S840 automatic mode provides a simple reset function.

Kliknij na “Reset Count” . The system will reset the processed count to zero. This is useful when you are switching to a different product or starting a fresh batch after completing a previous order.

How to Use Initial Bending

Sometimes you may need to restart the program from the very first bending step – for example, after an interruption or when restarting a production run.

Kliknij na “Initial bend” . The program will jump to the first step of the current program. Once you are ready, press the start button again to continue. This function ensures you don’t have to manually scroll back through steps or reload the program.

How to View Graphics in Automatic Mode

ESA S840 automatic mode also includes a graphic visualization feature to help you monitor the bending process.

Kliknij na “Graphics” to view the automatic graphic page. The graphic display shows the current bending step, tooling positions, and part profile. For more detailed information about graphic functions, please refer to the relevant sections of the KVARA S830-S840-S850 touch user manual.

Prerequisites for Starting Automatic Mode

Before you switch to ESA S840 automatic mode, ensure the following conditions are met:

1. Program is verified – Run at least one complete part in semi-automatic mode and confirm all bend angles, backgauge positions, and part dimensions.
2. Corrections are saved – Any angle or position corrections made in semi-automatic mode must be saved to the program.
3. Tooling is secure – Check that punches and dies are properly installed and clamped.
4. Material is loaded – Ensure a fresh stack of blanks is ready and properly aligned.
5. Safety devices are active – Light curtains, two-hand controls, and foot pedals must function correctly.

Step-by-Step: How to Smoothly Start ESA S840 Automatic Mode

Follow these steps for a smooth transition into ESA S840 automatic mode:

Step 1: Load the Verified Program

From the program list, select the program you have already tested and corrected. Press Obciążenie Lub Wybierać to bring it into the production interface.

Step 2: Switch to Automatic Mode

Click on the navigation bar icon to switch to automatic production mode. The screen will display the first bending step.

Step 3: Set Production Quantity (Optional)

If you have a specific batch size, click “Set quantity” and enter the desired number of parts. Otherwise, leave it at zero for continuous production.

Step 4: Perform a Safety Check

• Verify no one is inside the bending area
• Ensure the workpiece is correctly positioned against the backgauge
• Confirm the ram is at top dead center

Step 5: Start Production

Naciśnij przycisk start. The machine will now execute the entire program automatically. After each bend, the system advances to the next step without requiring additional input. The part count will increment automatically.

Monitoring Automatic Mode Operation

While ESA S840 automatic mode runs, you should monitor the following:

What to Watch	Dlaczego
Current step number	Ensures the program is advancing as expected
Angle and position values	Confirm corrections are being applied
Part quality after each piece	Spot-check every 5-10 parts
Machine sounds	Unusual noises may indicate tooling issues or overload
Production counter	Know when the job will finish
Graphic page	Visual confirmation of bend progress

Wskazówka: Even in automatic mode, never leave the machine unattended. Stay alert for misfeeds, material jams, or tooling wear.

How to Handle Interruptions in Automatic Mode

Sometimes you may need to pause or stop ESA S840 automatic mode:

Pausing

Naciśnij Zatrzymywać się button. The ram will return to top dead center, and the system will pause after completing the current bend. To resume, press Start – the machine will continue from the next bend.

Stopping Mid-Cycle

In an emergency, press the Zatrzymanie awaryjne button. The machine will halt immediately. After resolving the issue, you may need to jog the ram manually or use Initial bend to restart from the first step.

Changing Parameters on the Fly

You cannot edit bending parameters while ESA S840 automatic mode is running. To make adjustments, stop the machine, switch to semi-automatic or manual mode, edit the program, save, and then restart automatic mode.

Safety Best Practices for Automatic Mode

Running ESA S840 automatic mode at high speed requires strict safety discipline:

• Never bypass light curtains – They are your primary protection.
• Trzymaj ręce z dala – Use automatic parts handling or tools if you must reach near the bending area.
• Inspect tooling regularly – Worn tools can break and cause injury.
• Train operators – Only authorized personnel should start automatic mode.
• Use two-hand controls where required by your machine configuration.

Transitioning from Semi-Automatic to Automatic Mode

The safest way to begin using ESA S840 automatic mode is to follow this workflow:

1. Create or load a program – Enter all bend data.
2. Run first part in semi-automatic mode – Correct angles and positions as needed.
3. Save corrections – Ensure the program reflects the verified values.
4. Run a second part in semi-automatic tryb – Confirm the corrections work.
5. Switch to automatic mode for remaining parts – Now you can run continuously.

This method guarantees that your program is fully proven before you trust it to automatic operation, reducing scrap and rework.

Common Issues and Solutions in Automatic Mode

Issue	Likely Cause	Rozwiązanie
Machine stops after first bend	Incorrect step count or “Set quantity” reached	Check program steps and quantity setting
Angle out of specification	Correction not saved or material variation	Stop, measure, apply correction, resave
Backgauge position drifts	Loose mechanical coupling or axis error	Calibrate axis and tighten connections
Parts hit the backgauge during bending	Auxiliary refund value too small	Increase refund distance in program
Cycle time too long	Bending speed set too slow	Adjust axis parameters for faster speed
