1. 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). If you are not sure which method is config-
ured please contact your machine supplier.

The following picture shows a representation of the front panel.
The panel contains one display and several keys for program-
ming and axis control. The display will be explained in the next
section.
The keyboard contains the following keys:
• 10 numerical keys (0 - 9)
• decimal point
• plus/minus toggle
• clear key, to clear a parameter value
• enter key, to enter a typed value
• arrow keys, to select various parameters
• stop key (0) (incl. status LED)
• start key (1) (incl. status LED)

3. Operating modes
3.1 Introduction
The control has several modes for programming and operation:
It is indicated in the top of the screen which mode is active.
3.2 Basic navigation
• To switch between modes, press the <arrow up> key until
the mode symbol is highlighted. Then use the <arrow left>
and <arrow right> key to move to the required mode.
• To enter a mode press the arrow key down.
• Within a mode, use the arrow keys to move around between
parameters and fields.
• To program a parameter, move the cursor to the appropriate
symbol and type the required value. Press ENTER to con-

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.
• To start execution of a program, press the ‘Start' key.
3.3 Product programming
This programming screen in divided into three areas. From top
to bottom these are:
• Current Y and X position
• General product properties
• Table with bend steps, each step has several parameters
Select this symbol in the menu bar for prod-
uct programming and execution

V0413, 7
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.
3.4 Tool Selection
This screen displays an overview of the available tools. The
table indicates the tool number, the V-opening, the tool angle
and radius. During product programming, the programmed tool
properties are used for the calculation of Y-axis values. To enter
the tool properties place the cursor on the applicable field of a
tool and simply enter the desired value.
Select this symbol in the menu bar for tool
selection and programming.

3.5 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. The program constants menu can be exit by navigating to
the upper symbol menu with the arrow up key or by pressing the
STOP button to return directly to the automatic production mode.
Select this symbol in the menu bar for the
program constants

In the service screen the actual calibration point can be pro-
grammed and an overview of actual system information is avail-
able.
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).
This will be indicated with a lock
symbol in the upper right corner of
the screen

To access the System information screen place the cursor on
the System information screen parameter and press the enter
key. In the service information screen the following information is
viewed.
Calibration point
Refer to chapter 4 for details
System information screen
Software version: the version num-
ber of the installed application soft-
ware of the DA-41. This parameter is
read-only.
Serial number: the serial number of
the DA-41. This parameter is read-
only.
Memory usage: indicated how many
percent of the available memory is
used. This parameter is read-only.
Hours: the number of hours the
machine has been running. This
parameter is read-only.
Strokes: the number of bend strokes
the machine has executed. This
parameter is read-only.
Material properties menu:
In this menu the material properties
can be programmed. To access the
menu press the enter key, to exit
press the STOP button

Depending on the machine specifications one or more of the
below mentioned functions can be available on the program
constants screen.
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. Please contact the
machine documentation or contact
the machine supplier for the function
of this timer.
Decompresion time: The function of
this parameters is depending on the
machine design. Please contact the
machine documentation or contact
the machine supplier for the function
of this timer.
Current X-axis position. Program the
current position of the X-axis. The
control will retain this position value
after power-down and automatically
assumethesame positionvalueafter
power-on. After power-on, verify the
axis position and correct this param-
eter when necessary.This parameter
is only available in case there is no
reference system for this axis
installed on the machine.
X-axis correction.With this parameter
the correct position can be (re)cali-
brated.
Current Y-axis position. This parame-
ter works the same as for the X-axis.

3.6 Manual movement
Show bending force in Ton or kN.
Bending force correction factor. The
calculated force is multiplied by this
factor.
Wait for retract.
1 = Y-axis waits at pinch position until
the X-axis retract is completed.
0 = When the X-axis retract is
started, the Y-axis start to move to
the bend position
Select this symbol in the menu bar for the
manual movement screen

V0413, 14
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.
To move an axis at high speed, press the arrow key continu-
ously.
3.7 Product selection
Select this symbol in the menu bar for the
product selection screen

V0413, 15
The symbols above each column have the following meaning:
There are 100 product programs available in the control. To edit
a program, it must be selected first. By default, all programs con-
sist of 0 steps. As soon as a program has been selected, one
step is added to the program.
To select a program, move the cursor to the required program
number and press ENTER to select it. This program number is
also displayed in the upper right corner of the screen, beside the
mode symbol.
To select a program with a high number (e.g. 74), press the first
digit of this number (e.g. 7). The cursor will automatically jump to
the group of numbers that begin with this digit. Then use the
arrow keys to get to the correct program number.
When a program has been selected, the control automatically
switches to the programming mode.
A program remains active until another program is selected or
until it is deleted.
To delete a program, move the cursor to the program number
and press the clear key. The program number remains, but the
number of steps is reset to 0.

3.8 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.
If the control is locked, it is indicated by a lock symbol in the
upper left corner of the programming window.
When locked, the following operational restrictions apply:
• programs cannot be created or edited
• programs cannot be deleted
• tools cannot be created or edited
The following actions are still possible when the control is
locked:
• programs can be selected (if they consist of one or more
steps)
• programs can be executed
• Y-axis corrections within programs can be changed
• program constants can be changed
• axes can be moved through the manual movement screen
