- Database<\/strong>\u00a0\u2013 A collection of tables. You can have multiple databases (e.g., \u201cFERRO\u201d, \u201cINOX\u201d, \u201cALUM\u201d), but only one is active at a time.<\/li>\n\n\n\n
- Table<\/strong>\u00a0\u2013 Each table corresponds to a material number (1 to 99) and optional description.<\/li>\n\n\n\n
- Key Fields<\/strong>\u00a0\u2013 Identify a record uniquely. Examples: bend angle, sheet width, thickness, tools. Keys can have interpolation properties.<\/li>\n\n\n\n
- Correction Fields<\/strong>\u00a0\u2013 The actual correction values (e.g., Y1\u2011Y2 correction) associated with the keys.<\/li>\n<\/ul>\n\n\n\n
Each database has a fixed structure (which fields are keys, which are corrections) that you define once at creation and cannot change later.<\/p>\n\n\n\n
Properties of Key Fields<\/h3>\n\n\n\n
When creating a database, you assign each key field these properties:<\/p>\n\n\n\n
- \n
- Sorting<\/strong>\u00a0\u2013 Numeric index that determines the order of columns and rows.<\/li>\n\n\n\n
- Interpolation<\/strong>\u00a0\u2013 Yes\/No; if enabled, the system will interpolate correction values when an exact key match is not found.<\/li>\n\n\n\n
- Interpolation Range<\/strong>\u00a0\u2013 Maximum allowed difference between the two nearest key values (lower and upper) for interpolation to be applied.<\/li>\n<\/ul>\n\n\n\n
How to Create and Configure an ESA S650 Database<\/h2>\n\n\n\n

<\/figure>\n\n\n\nSetting the Active Database<\/h3>\n\n\n\n
Use 4>> Database Selection<\/strong> from the sub\u2011menu to choose the database you want to be active. Only one database is enabled at a time.<\/p>\n\n\n\n
Modifying Database Settings<\/h3>\n\n\n\n
After creation, you cannot change the structure (which fields are keys). However, you can change the sorting and interpolation settings of the keys using 2>> Modify DB Settings<\/strong>.<\/p>\n\n\n\n
Working with Tables and Records<\/h2>\n\n\n\n
Each material (material number) gets its own table inside the database.<\/p>\n\n\n\n
Selecting and Managing Tables<\/h3>\n\n\n\n
- \n
- To switch between material tables, use the arrow buttons (previous\/next table).<\/li>\n\n\n\n
- To delete the current table, press the delete table button and confirm.<\/li>\n\n\n\n
- To see a list of all tables, use\u00a0[Table Selection]<\/strong>\u00a0\u2013 choose a material by touching the screen.<\/li>\n<\/ul>\n\n\n\n
Adding, Modifying, and Deleting Rows<\/h3>\n\n\n\n
- \n
- [Add Row]<\/strong>\u00a0\u2013 Inserts a new correction record. You will be prompted to enter key values (angle, width, thickness, tools) and the associated correction.<\/li>\n\n\n\n
- [Modify Row]<\/strong>\u00a0\u2013 Edit the selected record. A window opens where you can change any key or correction value.<\/li>\n\n\n\n
- [Delete Row]<\/strong>\u00a0\u2013 Removes the currently selected record.<\/li>\n\n\n\n

<\/figure>\n\n\n\nEnabling and Using the Database in Daily Work<\/h2>\n\n\n\n
Once your database is populated, you must enable it to start automatic correction retrieval.<\/p>\n\n\n\n
Enabling the Database<\/h3>\n\n\n\n
- \n
- From the Corrections page, press the function key\u00a0[Enable KvaraDB]<\/strong>.<\/li>\n\n\n\n
- The icon in the top right corner confirms that the database is active.<\/li>\n<\/ul>\n\n\n\n
Automatic Correction Search<\/h3>\n\n\n\n
Whenever you fill a numeric or graphic program, the system constantly monitors the key fields (angle, width, thickness, tools<\/a>). If a matching record exists in the active material table, the corresponding correction (e.g., Y1\u2011Y2) is automatically inserted into the program\u2019s correction fields. If no exact match exists but interpolation is enabled, the system calculates a linear average between the nearest upper and lower records.<\/p>\n\n\n\n
Using Interpolation for Unknown Bends<\/h3>\n\n\n\n
Interpolation is a standout feature. Suppose you have corrections for bend angles 90\u00b0 and 100\u00b0, but you are bending at 95\u00b0. If interpolation is enabled, the database calculates a correction value by averaging the two known corrections. The interpolation range limits how far apart the two records can be \u2013 if the distance is larger than the range, interpolation is not performed. Setting interpolation range to 0 forces it to always interpolate.<\/p>\n\n\n\n
Thickness Tolerance<\/h3>\n\n\n\n
The database also includes a thickness tolerance parameter. If your program has a thickness of 2.1 mm, but only a record for 2.0 mm exists, the system will still use the 2.0 mm corrections provided the difference is within the set tolerance (e.g., 0.2 mm). This greatly expands the usability of your data.<\/p>\n\n\n\n
Acquiring Corrections \u2013 Manual and Self\u2011Learning Modes<\/h2>\n\n\n\n
The database is most valuable when it is continuously updated with real\u2011world corrections.<\/p>\n\n\n\n
Manual Acquisition<\/h3>\n\n\n\n
After making a correction in the Editor, Corrections, or Semiautomatic page, press the function key [Insert on KvaraDB]<\/strong>. The current correction values will be saved into the table corresponding to the active material. If that material table does not exist yet, the system asks you to enter a description and then creates it automatically.<\/p>\n\n\n\n
If you try to insert a record that already exists (same key values), the system will ask whether you want to replace it.<\/p>\n\n\n\n
Self\u2011Learning Mode<\/h3>\n\n\n\n
For the initial phase when the database is empty, enable Self\u2011Learning Mode<\/strong>:<\/p>\n\n\n\n
- \n
- From the Corrections page, press\u00a0[Enable self\u2011teach. KDB]<\/strong>.<\/li>\n\n\n\n
- In this mode, every time you change a correction in the Editor or Corrections page, it is automatically acquired \u2013 you do not need to press\u00a0[Insert on KvaraDB]<\/strong>.<\/li>\n\n\n\n
- The icon changes to \u201cKba\u201d in the top corner to indicate self\u2011learning is active.<\/li>\n<\/ul>\n\n\n\n
This mode simplifies building your first database.<\/p>\n\n\n\n
Database Management \u2013 Backup, Restore, and Deletion<\/h2>\n\n\n\n
Protect your hard\u2011earned data with USB backups.<\/p>\n\n\n\n
Saving and Loading Databases<\/strong><\/p>\n\n\n\n
From the Kvara Database sub\u2011menu:<\/p>\n\n\n\n
- \n
- 5>> Save current DB<\/strong>\u00a0\u2013 Saves the active database to a USB device.<\/li>\n\n\n\n
- 6>> Save all DB<\/strong>\u00a0\u2013 Saves every database present on the system to USB.<\/li>\n\n\n\n
- 7>> Load all DB<\/strong>\u00a0\u2013 Uploads all databases from USB back to the control.<\/li>\n<\/ul>\n\n\n\n
Deleting a Database<\/strong><\/p>\n\n\n\n
Select 3>> Delete Database<\/strong>, then choose the database from the list and confirm.<\/p>\n\n\n\n
Disabling Specific Corrections<\/strong><\/p>\n\n\n\n
Use 1>> Disable corrections<\/strong> to temporarily exclude one or more correction fields from being used in new programs \u2013 useful when testing different strategies.<\/p>\n\n\n\n
Using the Materials Table and Material Coefficients<\/h2>\n\n\n\n
Beyond the key\u2011correction database, the ESA S650 also provides a\u00a0Materials Table<\/strong> where you can set coefficients that multiply the stretch calculation (based on DIN 6935).<\/p>\n\n\n\n
![\"\"](\"https:\/\/www.harsle.com\/wp-content\/uploads\/2026\/04\/image-48.png\")
<\/figure>\n\n\n\nHow to Access the Materials Table<\/h3>\n\n\n\n
- \n
- Go to the Corrections page (press\u00a0C<\/strong>).<\/li>\n\n\n\n
- Press\u00a0[Materials list]<\/strong>.<\/li>\n<\/ul>\n\n\n\n
Setting Coefficient Values<\/h3>\n\n\n\n
- \n
- Each material (Aluminium, Sheet, Inox, etc.) can have up to three coefficients.<\/li>\n\n\n\n
- Default value is 1 (normal stretch). Set to 2 for double stretch, 0.5 for half stretch.<\/li>\n\n\n\n
- Range: 0 to 9 with up to 4 decimal places.<\/li>\n\n\n\n
- Setting all coefficients to 0 disables stretch calculation entirely \u2013 the graphic program development becomes the exact sum of segments.<\/li>\n<\/ul>\n\n\n\n
Saving and Loading Coefficients<\/h3>\n\n\n\n
- \n
- Save to USB using the save button on this page.<\/li>\n\n\n\n
- Load from USB using\u00a0[Load from disk]<\/strong>.<\/li>\n\n\n\n
- Coefficients are also included in the global Save ALL \/ Load ALL from the configuration page.<\/li>\n<\/ul>\n\n\n\n
Frequently Asked Questions(FAQ)<\/h2>\n\n\n
\n\n\nCan I change the structure (fields) of a database after it has been created?<\/strong><\/h3>\n
\n\nNo. Once a database is created, the set of key fields and correction fields is fixed. Plan carefully before creation. You can, however, modify sorting and interpolation settings via\u00a02>> Modify DB Settings<\/strong>.<\/p>\n\n<\/div>\n<\/div>\n
\nHow does the database handle multiple V\u2011dies on the same die?<\/strong><\/h3>\n
\n\nThe \u201cTools\u201d key field includes the die name, V\u2011die number (in brackets), and punch name \u2013 for example, \u201cB(1)-1\u201d. This allows separate corrections for different V\u2011die selections.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n
Conclusion<\/h2>\n\n\n\n
Effectively using the ESA S650 database transforms the way you set up bending programs. By creating a well\u2011structured database, populating it with real corrections (manually or via self\u2011learning), and enabling interpolation and thickness tolerance, you reduce manual entry and eliminate guesswork. The ability to save, load, and manage multiple databases on USB ensures your data is always safe and portable. The additional Materials Table coefficients give you fine control over stretch calculations.<\/p>\n\n\n\n
Now that you know how to effectively use the ESA S650 database, I encourage you to start by enabling self\u2011learning mode on a simple material (e.g., 2 mm mild steel). Run a few test bends, insert the corrections, and then watch how the database automatically applies them to your next program. For advanced setups, experiment with interpolation ranges and thickness tolerances.
