Page 5: Introduction
The DA-41 is a programmable control for conventional press brake machines. This manual assumes that the DA-41 is configured using the bending depth formula. If the unit is configured for bending depth calculation based on tables please refer to the version 2 user manual (8064-901C). - Page 6 V0413, 2...

firm the value. A programmed value is also confirmed when an arrow key is pressed. In some cases, the <arrow left/ right> keys can also be used to change values. • Steps and their parameters can only be programmed and viewed when the control is stopped. -
Page 11: Tool Selection
Delem In the upper right corner of the screen, the number of the cur- rently active program is shown. In this screen, a product program can be edited and executed. Programming of products will be explained in chapter 4. Tool Selection Select this symbol in the menu bar for tool selection and programming. -
Page 12: Program Constants
Program constants Select this symbol in the menu bar for the program constants In this screen, several control settings can be viewed and changed. Parameters (except the read-only ones) can be edited using the arrow keys (left and right) or they can be programmed numeri- cally. - Page 13 Delem Service menu: To access the service menu type the code 456 followed by the enter key. To exit the service menu press the STOP button Note: when enter the enter key is pressed without the specified code the calibration point will be displayed but cannot be changed (read only).

Retract time: The moment of X-axis retract is delayed by the value pro- grammed for this parameter. The value is programmed in seconds. Bending time: The function of this parameters is depending on the machine design.

In this screen the X- and Y-axis can be moved manually with the arrow keys. This can only be done when the control is not started. By using the arrow keys up and down the Y or X-axis can be selected. To move an axis gradually, press the left or right arrow key once. - Page 19 Delem The symbols above each column have the following meaning: Current selected product. The number of bends in this product. Material ID number in this product. Sheet thickness of this product. Used tool in this product. There are 100 product programs available in the control. To edit a program, it must be selected first.

Page 20: Key Lock
Key lock The control is equipped with a key lock function, to prevent unauthorised programming. Whether the key lock function is available or not depends on the machine specifications. If the control is unlocked, it can be programmed as described in this manual. -
Page 21: Programming Products And Tools
Delem Programming products and tools Introduction Programming of products and tools can be done very straightfor- ward. Normally, bend programs can only be programmed when tools and materials are available, so they must be programmed first. In order to execute the programmed product successfully the calibration point should be set correctly. - Page 22 After the enter key is pressed the following screen will be dis- played. In this example the calibration point is 105.71mm. V0413, 18...
- Page 23 Delem Note: when enter the enter key is pressed without the specified code the calibration point will be displayed but cannot be changed (read only). This will be indicated with a lock symbol in the upper right corner of the screen.

Page 24: Tool Programming
Tool programming In order to program or modify a tool select the tool symbol in the menu bar. A total of 15 different tools can be programmed. A tool is programmed by entering a few essential tool values. These values will be used for automatic bend depth calculation during bend programming. -

Delem Radius of the die. Product programming In order to create a new product, or modify an existing product select the desired product number in the product selection menu. After this switch to the programming screen. This is described in the next paragraph. - Page 26 Number of the tool which is used for this product.If the cursor is on the tool icon the tool selection menu can be selected by pressing the left arrow key. Material ID number. Sheet thickness of this product. Product width. This value is used for bend- ing force calculation.
- Page 27 Delem Y-axis bend depth. When an angle is programmed, this value is calculated. A higher value means a lower beam position. Angle correction on the Y-axis. When angle programming is used, this cor- rection is used to correct Y-axis values. A positive correction means a lower beam position.

Page 29: Program Delete
Delem To delete a bend from the program: Select the number of the bend step that should be deleted. Press the CLEAR key; the selected bend step will be deleted. The succeeding bend steps are shifted up. The first bend cannot be deleted in the programming screen. -
Page 30: Production Mode
Production mode Program execution is carried out from the programming screen. From here, it is possible to execute one or more bend steps. When started the actual Y and X-axis positions, together with the Stockcount value are displayed in a larger font. To start a program, press ‘Start’. - Page 31 Delem Programs can only be executed on the machine when the pump for the hydraulic system is running. If the controller is started when the pump is not running a message will be displayed. Press the enter key to clear the message from the screen.

Page 32: Diagnostics
Diagnostic screen If the START or STOP button is pressed for 2 seconds in the automatic mode screen the DA-41 will enter its build in diagnos- tic screen. In total there are 3 screens, the arrow keys up and down can be used to navigate through the screens. The diag- nostic mode can be switched off by pressing the STOP key for 2 seconds again. - Page 33 Delem Mentioned below are the possible machine states: S0 -> Stopped S1 -> Positioning S2 -> Wait for Retract S3 -> Wait for LDP S4 -> Opening S5 -> Wait for STEP S6 -> Wait for X-delay Screen2: Digital input and output signals The status of all digital input and output signals is displayed.

Page 34: Error Messages
The state of all digital inputs, analog outputs and encoder are displayed. Error messages The DA-41 controller has a build in error messaging system. The messages can be set to inform the user about the possible rea- son why a certain action cannot be executed by the controller. - Page 35 Delem Invalid tool data: This message indicates that the tool data is not programmed, is invalid or not com- pleet.
