Looking to optimize the DELEM DA-69S Settings Mode? You’re in the right place. This guide will walk you through the essential setup steps for the DELEM DA-69S, ensuring a clear understanding of each process.

Whether you’re setting it up for the first time or fine-tuning your configuration, this guide is designed to enhance efficiency and accuracy in your operations. Dive in to learn how to configure your DELEM DA-69S Settings Mode for optimal results.

Step 1: Accessing the DELEM DA-69S Settings Mode

This mode is a gateway to a variety of settings that can optimize your machine’s performance. You’ll find these options neatly organized into tabs, which can be easily navigated by tapping and dragging when necessary.

Since there can be more tabs than the screen can show in one view, dragging the tabs in vertical direction enables to view and select all available tabs.

Step 2: Configuring General Parameters

Within the General tab, you can adjust fundamental parameters like units of measurement. Choose between inches and millimeters for length, and select Tons or KN for force. Also, change the user interface language to your preference by selecting from the available options. If required, you can install additional help languages.

• Help language

The help language for the online Help function in the DELEM DA-69S Settings Mode is by default set to the same language as the user interface. If that language is not available as online Help, English is chosen.

When Help Language is selected in the DELEM DA-69S Settings Mode, the additional function Add Help Language appears. With this function, you can install a new help language on the control. Make sure the required help file is present on the control disk or another accessible location (network, USB stick). It will automatically be selected and installed.

• Keyboard Layout
  • In the DELEM DA-69S Settings Mode, you can select your preferred keyboard layout. Options include Qwerty, Qwertz, or Azerty.
• Key Sound
  • The DELEM DA-69S Settings Mode allows you to switch the sound function of the input panel on or off, based on your preference.
• Message Sound
  • Within the DELEM DA-69S Settings Mode, there is a parameter to enable or disable sound for messages, depending on the message type:
    • All messages: Sound is on for all messages.
    • Errors + Warnings: Sound is on only for errors and warnings.
    • Errors: Sound is on only for errors.
    • None: Sound is off for all messages.
• Command Panel Side
  • The DELEM DA-69S Settings Mode provides an option to switch the command panel to the left side of the screen.

Step 3: Setting Material Properties

The Materials tab allows you to program up to 99 different materials.

For each material 3 properties are present and can be viewed and edited.

1. Material Name:
   • The name of the material as it appears in the DELEM DA-69S programming screens.
   • Maximum length: 25 characters.
   • Must begin with a letter, not a numeral.
2. Tensile Strength:
   • Enter the tensile strength of the material, as it is essential for accurate bending calculations in DELEM DA-69S Settings Mode.
3. E Module:
   • Provide the E-module (modulus of elasticity) for the material, crucial for the DELEM DA-69S Settings Mode to perform calculations.
4. Strain Hardening Exponent (n):
   • A material property that should be provided by the supplier, similar to tensile strength and E-module.
   • Accurate values improve the inner radius calculation, leading to more precise bending depth and bend allowance in DELEM DA-69S Settings Mode.
   • Range: 0.01 – 1.00. Default is set to _.__, indicating n is not active.
   • Entering 0 resets the value to _.__.
   • Typical value for mild steel: 0.21.
5. Calculate n:
   • Supplier should provide the n value. Alternatively, it can be derived from the bend allowance.
   • Without a bend allowance table, perform a test bend in Manual mode.
   • Switch to the materials table and tap ‘calculate n’ within the DELEM DA-69S Settings Mode.

No bend allowance table:

When no bend allowance table is active in the DELEM DA-69S Settings Mode, perform a test bend in Manual mode. Tap ‘calculate n’ in the materials table to enter measured side length after bending.

The DELEM DA-69S calculates bend allowance and strain hardening exponent (n) using the difference between programmed X-axis and measured length. Accuracy depends on precise sheet thickness, tool parameters, and side length measurement.

With bend allowance table:

In the DELEM DA-69S Settings Mode, when a bend allowance table is active, you can derive the strain hardening exponent. Select parameter n for a material and tap ‘calculate n’. The result appears in the input line.

Materials are listed by their ID and can be sorted by tapping column titles. To modify a material, select it and change values. To delete, select and use Delete Material. To add a new material, choose an empty line and enter values.

Step 4: Backup and Restore Options

In the Backup/Restore tab, safeguard your work by backing up products, tools, and settings. Use available media options, such as a USB stick or network, to secure your data.

the backup directory involves selecting a device (e.g., USB stick, network) and a directory. Device choice depends on what is connected to the control. New directories can be created and selected as needed. Backup locations for storing products and tools can be set independently.

Product backup and restore

To make a backup of programs to disk, choose ‘products’ in the Backup section on the Backup/restore page.

When the initial backup directory has been set, the products backup screen appears.

In the backup screen the products in the selected directory are shown.

Performing the Backup:

• Select products to backup by tapping them in the list; a backup marker confirms the selection.
• If a file exists in the backup location, decide whether to replace it.
• To backup all products at once, simply tap “All”.
• Adjust the source of products with “Source Directory” and navigate to the correct directory. Similarly, set the desired backup destination with “Backup Directory”.

To restore programs to the control, choose ‘products’ in the Restore section on the Backup/ restore page.

When the initial restore directory has been set, the products restore screen appears.

In the restore screen the products in the selected directory are shown.

Performing the Restore:

• Select products to restore by tapping them in the list; a restore marker confirms the selection.
• Decide whether to replace existing files if a duplicate name is found on the control.
• Adjust the source location with “Restore Directory” and navigate to the chosen directory. Similarly, set the destination location on the control with “Destination Directory”.

Tool backup and restore

To make a backup of tools to disk, choose ‘tools’ in the Backup section on the Backup/restore page.

When the initial backup directory has been set, the tools backup screen appears.

With this menu a back-up of tools on the control can be made: punches, dies or machine shapes. The procedures for a tool back-up run similar to the procedures for a product back-up.

The restore procedures for tools run similar to the procedures for a product restore.

Backup and restore for Tables and Settings

For DELEM DA-69S Settings Mode, the Backup/Restore tab provides essential features for user-specific settings and tables. This procedure closely resembles the backup and restore process for products and tools. The ‘All’ function streamlines this process by automatically executing all steps sequentially, covering Backup or Restore for Products, Tools, Tables, and Settings.

Automatic scheduled backups

In the DELEM DA-69S Settings Mode, you can automate the ‘backup all’ function by selecting ‘backup schedule’ on the backup/restore page. Set intervals from 1 to 31 days. If the control is ready and time is due, a prompt asks to backup now or remind later. The reminder, by default 1 hour, can be adjusted between 1 to 24 hours. Choose the desired backup location for optimal system management.

Directory navigation

When Backup directory is used, a new window appears with a list of available backup directories.

In this window you can browse through the directory structure of your backup device. To select the directory you are currently in, tap Select.

• Device Navigation: Switch devices by tapping the top level, choosing your device, and selecting the desired subdirectory.
• Network Connection: If available, select Network, choose a network volume, and then proceed as with other devices.
• Directory Management: Use Make subdir to create new subdirectories and Remove subdir to delete existing ones.
• Subdirectory Access: Navigate and select subdirectories by tapping them, then tap Select to choose.

Step 5: Tailoring Program Settings

Navigate to Program Settings to adjust parameters that influence production processes.

• Angle correction database

Enable the Angle Correction Database in the DELEM DA-69S Settings Mode to optimize production efficiency. This feature allows angle corrections made in Automatic Mode to be stored within the product program, ensuring they are available for future use.

When activated, the system checks if corrections exist for similar bends during production, offering them if available. The database updates with new corrections entered during production.

For a bend to be considered similar, properties such as material properties, thickness, die opening, die radius, and punch radius must match exactly, while angle differences must not exceed 10°. Interpolated corrections are offered unless adjacent bend differences exceed 5°.

• Initial angle correction

The initial angle correction feature allows programming of small angle adjustments independently of the “Angle correction database”. This parameter can be accessed on the corrections page in both Automatic and Manual modes. It does not appear on the main page in these modes. The total angle correction is the sum of the visualized correction and the initial correction.

Example: If you program an angle correction of -8 degrees and an initial correction of -6 degrees, the total correction remains constant. The visualized correction adjusts from -8 degrees to -2 degrees.

Setting the feature to “enabled” allows initial angle corrections on the corrections page, while “disabled” restricts this function.

• General angle correction programming

To program general angle corrections which are used in all bends of the program.

These angle corrections are not related to specific bend angles and therefore not stored in the angle correction database.

disabled => no general angle corrections.

enabled => only G-corr. α1.

α1 and α2 => G-corr. α1 and G-corr. α2.

• Manual mode store angle corrections

To enable the storage of angle corrections programmed in Manual mode. Corrections can be derived from bend results in Manual mode which later can be used during product programming.

• Angle correction programming

Parameter to switch between copying or keeping the delta values or changing independently when changing angle corrections in production mode.

copy => copy Cα1 to Cα2 when changing Cα1.

delta => keep delta between Cα1 and Cα2 when changing Cα1.

independent => change Cα1 and Cα2 independently.

• X correction programming

Parameter to switch between copying or keeping the delta values or changing independently when changing the X-axis corrections in production mode.

copy => copy CX1 to CX2 when changing CX1.

delta => keep delta between CX1 and CX2 when changing CX1.

independent => change CX1 and CX2 independently.

Only available when an X2-axis is present.

• Y1/Y2 independent

Parameter to program the two Y-axes independently.

off => single Y-axis programming.

on => program Y1 and Y2 separately

• Recomputation of numerical values

Parameters in Manual mode and Program mode can be programmed one by one. This parameter determines the influence of a parameter change on other parameters.

disabled => the influenced parameters are only recomputed when over-entering, accepting the proposed changed values.

enabled => the influenced parameters are recomputed automatically.

• Machine ID and check

In the DELEM DA-69S Settings Mode, assigning a unique Machine ID to each bending machine in a factory is crucial. This ID ensures that when a program is loaded from a backup medium, the correct machine is identified. If the Machine ID doesn’t match, confirmation is required; otherwise, the action is aborted. To enhance workflow, this Machine ID check can be disabled if needed.

• Machine description

Additionally, within the DELEM DA-69S configuration, a detailed machine description can be entered. This description is utilized in the offline Profile-T for a comprehensive overview of available machines, aiding in identifying which machine corresponds to each control.

Step 6: Defining Default Values

Optimize your use of the DELEM DA-69S Settings Mode with this concise guide to default parameters.

• Y Opening Default: Sets the initial Y-axis opening value for new programs.
• Default Pressing Speed: Establishes the initial pressing speed in bend programs.
• Default Decompression Speed: Provides the initial decompression speed in bend programs.
• Default Dwell Time: Defines the initial dwell time value in bend programs.
• Default X-axis Speed: Sets the initial X-axis speed for new bend programs.
• Default Wait for Retract: Determines control behavior by setting a default retract wait time in bend programs.
• Default Step Change Code: Controls step change timing within a bend program with a specified code.
• Default Delay Time: Adjusts the X-axis waiting time at step change for better product handling.
• Default Prebend Angle: Sets the default prebend angle for graphical products.
• Default Hem Opening: Calculates beam position for hem bends, starts at 0.0mm for complete flange contact.
• Default Dimensions: Defines default dimension type (inside or outside) for graphical product drawings.
• Default Material: Chooses the initial material selection for new products or programs.
• Default Radius: Sets the initial radius value in the product properties dialog.
• Default Bend Allowance: Provides a starting value for bend allowance in product properties.

By understanding these DELEM DA-69S default settings, you can effectively configure your bend programs and product drawings for optimal precision and efficiency.

Step 7: Adjusting Computation Settings

The control offers two methods for bend allowance calculation:

1. Computation: Utilizes the standard formula embedded in the control to compute bend allowance.
2. Table: Employs a pre-defined bend allowance table with specific correction values.

When the parameter ‘Active Bend Allowance Table’ is selected, an extra function—Edit Table—becomes accessible. This function allows users to modify the table to suit custom requirements. The table opens in a separate window featuring its own set of controls for easy editing.

In the DELEM DA-69S Settings Mode, use the Tab key to select and edit table entries, pressing ENTER to save changes. Note: table creation isn’t possible here; you can only edit loaded tables. Refer to the Delem manual for bend-allowance tables. To load a table, select ‘Load Table’ to choose the file location.

1. Data Preparation Bend Allowance:
   • Correction Off: No bend-allowance is added to numerical programming.
   • Correction On: Bend-allowance correction is added to numerical programming.
   • This setting influences programmed values during product programming in Program mode, impacting axis corrections stored in the program. Note that this does not affect the Drawing mode during control post-processing, where bend-allowance is always considered.
2. Bottoming Force Factor:
   • Determines the bottoming force by multiplying the air bend force with this factor.
3. Z-Distance:
   • Defines the distance from the edge of the finger to the corner of the sheet.
   • For systems with automatic Z-axes, finger positions are auto-calculated with reference to the sheet end.

Step 8: Fine-tuning Production Settings

Stock Count Mode

• Down Counting: The stock counter decreases with each product cycle. The system halts when it reaches zero, resetting upon the next start.

• Up Counting: Increments the counter per product cycle, useful for progress reporting.

Auto Bend Change Mode Step

• Disabled: Requires manual selection and starting of next bending parameters.

• Enabled: Automatically loads the next bending parameters; requires start button press for axis positioning.

Parallelism Offset

Program an overall parallelism for the Y-axis stroke, ensuring it stays within allowed values during production.

Lock Touch Screen When Started

Option to lock the touch screen during operation to prevent unintended changes.

Pressure Correction

Adjusts the percentage of calculated force to control the pressure valve accurately.

Clamping Correction

Allows offsetting of the beam for firm sheet clamping. Positive values deepen the position; negative values raise it.

Default Part Support Return Speed

Sets return speed of part support post-bending as a percentage of maximum speed (if part support is available).

X-Safety Offset

Defines a minimum X-axis safety zone to prevent collisions with machine components during R-axis operations.

Intermediate X for Z-movement

The Intermediate X parameter in DELEM DA-69S is key for collision avoidance during Z-axis movement. It establishes a standard X-axis safety zone used across all programs.

1. Purpose: Sets a temporary safe X-axis value to prevent collisions, particularly with varying die sizes. Not to be confused with ‘X-safety offset.’
2. Functionality:
   • Value 0 disables the feature.
   • Ensures a consistent safety zone.
3. Usage in Die Operations:
   • Set Intermediate X-value larger than the largest die’s safety zone for effective clearance.
4. Movement Scenarios:
   • Both X-positions Outside: X and Z move simultaneously.
   • Old Outside, New Inside: Z moves first, then X.
   • Old Inside, New Outside: X moves first, then Z.
   • Both Inside: Backgauge moves to Intermediate X, then Z, followed by X to the new position.

Intermediate R for X-movement

• Purpose:
  • Used to prevent collisions during X-axis movements by temporarily adjusting the R-axis position.
• Functionality:
  • Setting the value to 0 disables this feature.
  • When set to a non-zero value, the feature activates while the X-axis enters the die’s safety zone.
• Process Sequence:
  1. R-axis moves to an intermediate position.
  2. X-axis shifts to the required position.
  3. R-axis returns to its intended position.
• Safety Zone Definition:
  • SZ (Safety Zone): Calculated as X-safety offset plus SD.
  • Components:
    • X-safety offset: The designated safety zone of the die.
    • SD (Safety Distance): Specified by the machine supplier.

Intermediate R for Z-movement

Setting this parameter to a value other than 0 activates a temporary R-axis position, ensuring safe Z-axis movement when the backgauge finger is within the die’s safety zone. Adjust this setting for optimal performance and increased operational safety.

The sequence will be as follows:

• The R-axis is moved to the intermediate position;

• then the Z-axis is moved to its intended position;

• finally the R-axis is moved to its intended position.

In the DELEM DA-69S Settings Mode, it’s possible to configure the system to automatically display bend step notes when the automatic mode is initiated and a new bend is selected. By enabling this parameter, the notes are presented automatically in the automatic mode.

Step 9: Configuring Network and Time Settings

Production time calculation

Explore the DELEM DA-69S Settings Mode for efficient production time calculation in the bend sequence process. Production time is influenced by the axes’ positioning speed and product handling, both of which depend on machine settings.

Product handling time varies based on dimensions, such as length and width. Smaller products in the Z-direction are turned quickly, while longer products in the X-direction need more time for front-to-back or combination turns.

Adjust turn times in seconds using four length intervals marked by three boundaries. Each interval allows for specific turn time settings. Boundaries 1/2/3 define product size categories.

Time settings

Display time

Display date and time on the title panel, time only or no time at all.

Time format

Display the time in 24 hours or 12 hours format.

Date format

Display the date in dd-mm-yyyy, mm-dd-yyyy or yyyy-mm-dd format.

Adjust time

To adjust the date and time. Adjusting the date and time will also adjust the date and time of the operating system.

Network settings

With the Network option on the DELEM DA-69S, the Settings Mode includes a Network tab featuring Network settings, diagnostics, Local shares, and Remote shares for enhanced connectivity.

For setting the network connection several standard network parameters are available that must be set with help of your system administrator.

To check the basic functionality of data transfer on the network some diagnostic tools are available.

To share local directories of your CNC to have them accessible on the network it is possible to enable the required information.

Optimize your DELEM DA-69S Settings Mode by sharing remote directories on the network. Access these from the CNC and easily add or remove shares as needed for improved efficiency.
