Several control settings.

V0220, 8
The several modes are explained in detail in chapters 3 to 6.
2.3 Key lock
The control is equipped with a key lock function, to prevent
unauthorised programming.
It depends on the machine if this lock is accessible over the
touch screen interface (upper left corner) or an external physical
key switch.
To lock or unlock the controller, tap the key lock to open the on
screen keyboard. Enter code 42 and press enter. You will see
the status of the key lock is toggled from closed to open or from
open to closed.
If the control is unlocked (key lock is open), it can be
programmed as described in this manual. If locked (key lock
closed), the following 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,
• settings can be changed,
• axes can be moved in manual movement mode,
• in the manual mode it is still possible to program and
execute one step.

There is a second code available for the key lock function. When
code 21 is entered instead of code 42 the user interface is
blocked. This can be used to block the machine from
unauthorized use without switching the machine off. This special
blocked stage can be recognized by an orange colored key lock
symbol:
To release the controller for normal operation, tap the key lock
symbol and enter code 21 followed by enter.

This action is permanent!

V0220, 13
3.3 Create a new program
To create a new program, select the new program soft key. The
DA-40T will open the keyboard so the program name can be
entered. If an already existing name is entered the DA-40T will
prompt a message and asks if the existing program should be
overwritten or not. In case the name was unique the DA-40T will
switch automatically to the automatic mode screen. In automatic
mode the several program steps can be defined. See for details
chapter 4.
3.4 Column sorting and changing column positions
Column sorting and changing column width/position are
available in program selection and automatic mode all steps
screens.
Column sorting
To Sort the data tap shortly in the middle of the column header.
To change from ascending to descending tap shortly in the
middle of the column header again. The column that is sorted is
marked with an orange arrow (see the Product header above).

column position.

V0220, 15
4. Automatic mode
In Automatic mode a bending program can be defined or edited
as explained in chapter 3.
This chapter describes all possible parameters that can be
programmed for a program step. Note that most of these
parameters are machine configuration dependent; it might be
that some of the parameters shown are not present in the user
interface.
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. Refer to paragraph
6.7.1 for setting the calibration point, and paragraph 6.2 for tool
programming.
4.1 Properties
The ‘Properties’ tab defines the general parameters that apply
for all program steps.
By tapping the navigation button Automatic
mode, the control is switched to Automatic
mode.

V0220, 16
Material number
The material of the sheet. There are 6
material types available. Material properties
can be programmed in Settings mode, as
described in paragraph 6.3.
Thickness
The thickness of the sheet.
Product width
This value is used for bending force
calculation.
Stock counter
To count the number of products. If
programmed to 0, the counter will increase
after each finished product. If programmed
higher than zero, the counter will count
down. When it has reached 0, the control
will stop. The stock counter will be reset to
the initally programmed value when ‘start’ is
pressed.

V0220, 17
4.2 All steps
In the ‘All steps’ tab the actual program step parameters are
defined. A program consists of a minimum of 1 program step
and a maximum of 25 program steps.
Start programming by entering values in the parameter fields.
Some parameters are set automatically and can be changed if
desired. If there are more parameters available than fits the
screen, use the pan function to make the parameters visible. If
desired, the order of parameters can be changed, see
paragraph 3.4.
A single step can be inserted or deleted at any point in the
program.
Die IDThe name (ID) of the selected die, which is
used for this product.

V0220, 18
Insert step
Select the number of the step after which one a step should be
inserted (To add a step select the last step in the program).
Press the ‘insert step’ soft key; a copy of the selected step will
be inserted. The cursor will automatically move to the new step.
Mark step
Select the number of the step that should be moved or swapped.
Press the ‘mark step’ soft key. Then select the next program
step and press the ‘move step’ soft key to move the marked step
to the selected position, or press the ‘swap steps’ soft key to
swap the marked step with the selected step
Delete step
Select the number of the step that should be deleted. Press the
‘delete step’ soft key; the selected step will be deleted. The
succeeding steps are shifted up.
A complete program can be deleted in the program selection
mode.
4.3 All steps parameters
Each line represents one step. The first column contains the
step number. For each step, the following parameters can be
programmed.
AngleThe desired angle value. This parameter is
available when a tool is programmed.
Angle correction
When angle programming is used, this
correction is used to correct Y-axis values.
A positive correction means a lower beam
position.

V0220, 19
4.4 Program execution
When all the program steps have been programmed (or an
existing program is selected) the program can be executed to
Y-axis bend depth
When an angle is programmed, this value
is calculated. A higher value means a lower
beam position.
Y-axis opening time
The desired opening time after a bend,
programmed as a percentage of the
maximum opening time.
Y-axis high speed
To enable high travel speed for the beam
during this bend.
X-axis position
The desired backgauge position for this
bend.
X-axis retract
Backgauge retract distance.
X-axis delay time
Delay time in seconds for X-axis and FD
axis after a step change.
Bending force
The calculated bending force.
Function output
