1.5. Getting started
1.5.1. Introduction

In order to obtain a bend program for a product, the control offers the
possibility to create a product drawing and calculate a valid bend
sequence for the product. With this information, a product program is
generated.
This is done with the following steps:
1. Go to the Products mode in the navigation panel and start a new
product by tap ping New Product.
2. Enter the product properties and start to draw a 2D product
proOle in the Drawing mode.
3. Check the tooling, modify or make a new set-up in the Tool Setup
:
 3. Check the tooling, modify or make a new set-up in the Tool Setup
mode.
4. Use the Bend Sequence mode to determine the bend sequence
by calculating it.
or manually modifying it upon your own idea’s.
5. When required modify the numerical CNC program via the
Program mode.
a. Tap Auto and press the Start button in order to produce the
programmed product.
1.5.2. Preparations

Before product programming can be started, the following

preparations must be made.
• The correct material properties must have been programmed in the
Materials library. You can Ond this on the Materials page in the
Settings mode.
• The correct tools must be programmed in the Tool Library. Tools are
necessary to create a CNC program. You can Ond the libraries for the
different types of tools in the Machine mode.
1.5.3. Create a drawing

The control offers the functionality to create a drawing of the

intended product. With this drawing application, tap Drawing in the
navigation panel, a 2D proOle is created. At this stage, there is no
calculation of bends or dimensions: any proOle or drawing can be
created.
The drawing method on the Touch screen control is based on:
Sketching
Value setting
Sketching
The product as well as tool shape Sketching can be done by tapping
on the screen in the different directions the drawing must have. The
application will follow the tapping with drawing a line between the
indicated points. The last point of the design will show always a big
:
indicated points. The last point of the design will show always a big
red dot. When the drawing dot is on the screen you can hold your
Onger on this position and move the Onger across the screen to move
the connected line in another required direction or make the line
length longer. This method is the so-called ‘Dragging’ facility. The
length and angle value will be visible on the screen and can be
adjusted to be exact or close to the requested value.
Value Setting
Once the product or tool is drawn in the Sketching method the exact
values of line lengths and angles can be optimized by the Value
setting method. Just tap 2 times on the value of the line length or
angle to change and the keyboard will pop-up. The value can be
entered in 2 ways of conOrmation:
Enter function
Enter-Next function
The Enter function will close the keyboard after entering the value.
The Enter-Next function will enter the value on the line or angle to
change and the keyboard will remain opened for the next
programming step.
In case the typed value is erroneous, the “undo” button right from the
input Oeld can be tapped to return to the original value or the
backspace key on the keyboard to delete the last typed character.
Zoom Function

By pinching the screen with two Ongers simultaeously one can zoom
in and out on the drawing, tool or machine visualisation. By spreading
Ongers the system will zoom-in, by bringing Ongers nearer to each
other the system will zoom-out.
Fit-To-Screen
In the command icons on the side of the screen you will Ond a Fit-To-
Screen function. This can be used when the drawing size is not clear
:

1.5.4. Determine bend sequence

When the product drawing is completed, the control offers Tool setup
mode to program the exact tool set-up as it is organised on the
machine. After this you can select the Bend Sequence mode to

determine and simulate the required bend sequence.

In the Bend Sequence mode, the control shows the product, the
machine and the tools. In this menu the bend sequence can be
programmed and checked visually. When a bend sequence has been
determined, the CNC program can be generated.

Programmable Onger positions
1.5.5. Numerical program

The Program menu gives access to the numerical program and

values of the active product.
There are two possibilities to create a CNC program:
enter a numerical program, started via Products mode, tap New
Program, step by step;
generate the program from the graphical bend simulation started
via the Products mode, tap New Product, via the Drawing mode.
(see: Drawing mode; product drawing).
If the program is entered by hand, there is no collision check. All
program values must be entered manually. The program depends on
operator experience.
If the program is generated from a graphical bend sequence, the
program can be visualised during production. A generated program
can be edited according to operation needs.
When a drawing has been completed with a bend sequence, and the
program is stored, the program is post processed and the numerical
program becomes available.
The system automatically computes :
Necessary force
Machine adjustments such as:
:
 Y-axis position
Decompression
X-axis position
X-axis retract
Y-opening
R-axes
Z-axes
Axes positions are calculated according to the machine
conOguration.
1.5.6. The Auto menu and Manual menu, production modes

A product program can be executed via the Auto mode. In Automatic

mode, a complete program can be executed bend after bend. In the
Auto mode the Step mode can be selected to have each bend started
separately.
The Manual mode of the control is an independent production mode.
In this mode, one bend can be programmed and executed. It is
typically used to test the behaviour of the bend system.
More information about this can be found in chapters 7 and 8.
1.5.7. Back-up data, external storage

Both product and tool Oles can be stored externally. Depending on

the conOguration, these Oles can be stored on a network or on a USB
stick. This facilitates a back-up of important data and the possibility
to exchange Oles between Delem controls.
1.6. Programming aids
1.6.1. Help text

This control is equipped with an on-line Help function. When the

Help-button in the navigation panel is pressed context sensitive help
will be provided.

values. When selecting such a parameter, by tapping the parameter
line on the screen, the list of options will open up near the position
:
line on the screen, the list of options will open up near the position
where you tapped the line, and the desired value can be selected.

To undo the selection and the opened listbox, tapping outside the
box will make it close without changing the selected parameter.

To improve the focus on parameters, and to ease the use while

programming, the parameter zoom function will enlarge speciOc
parameterlines when being programmed.
eg. force in Program mode, the force lines will expand giving them
better focus while One tuning.
:
When selecting any other parameterline, the previous selection will
be reduced and zoomed out again, as the newly selected
parameterline will be zoomed in at.
1.6.3. Navigation

Within some modes, the program screens are divided into tabs.
:
The tabs can easily be selected by just tapping them. When a tab is
not completely visible or not visible at all, just by dragging the tab row
horizontally, the desired tab can be “pulled” in sight and be selected.
1.6.4. Text input and editing

The cursor can be used to enter a speciOc value or text within an

existing input. Just tap at the desired position to do so. The cursor
will appear and input will be added there.
1.6.5. Typing alphanumeric characters vs. special characters

Both alphanumeric characters and special characters can be used

throughout the control. A full on-screen alphanumerical keyboard will
pop up when required.
When editing a Oeld which is pure numeric, the alphanumeric
characters will be hidden. For Oelds which enable to use
alphanumerical strings, the keyboard is completely available.
Special characters as ? % – can be found using the special character
button on the left-lower side of the keyboard.
:
Special characters (like á, à, â, ã, ä, å, æ) are supported by the on
screen keyboard by keeping a character (like ‘a’) pressed.
1.6.6. Messages centre

When messages are displayed coming from PLC, Safety systems or

the Sequencer, these messages can be ‘send’ to the ‘Messages
centre’. When a message is displayed simultaneously the message
centre symbol is shown in the top row of the page header, next to eg.
the keylock symbol. When tapping this message centre symbol the
:
the keylock symbol. When tapping this message centre symbol the
messages are taken from the screen, giving way for normal
programming and editing. When tapping again the actual messages
are shown.
When messages are in the background, the message centre symbol
has an extra indicator to show new incoming messages which are
not yet shown.
1.6.7. Keylock function

To prevent for changes to products or programs, the keylock function

offers the possibility to lock the control.

There are two levels of locking the control. Program Lock and
Machine Lock.
In Program Lock, only a product can be selected and executed in
Automatic mode.
In Machine Lock, the machine is locked and the control can not
be used.
To lock a control just tap the lock symbol in the top of the screen.
Depending on the code which is used, the control will be in Program
Lock or Machine Lock. Program Lock wil show a closed lock in grey.
Machine lock will show the same lock but colored (red).
:
Lock symbols when Program Lock is active will also appear behind
parameters to show the lock is active and modiOcation is not
possible.

To unlock the control, tap the lock symbol and enter the appropriate
code. After entering, the lock symbol will show it is unlocked and the
lock symbols behind parameters will disappear.
:
Codes can be changed upon desire. The procedure to manages
codes can be found in the Installation manual.
1.6.8. Manual positioning

On the manual positioning page in Manual mode and Automatic

mode a slider at the bottom of the screen can be used to position the
axis. The distance moved with the slider determines the speed of the
axis. When the slider is released, the axis stops. The buttons at each
end of the slider can be used to One-tune the axis position. When
“sliding” the beeper gives feedback that the axis is moving.
:
1.6.9. Software versions

The version of the software in your control is displayed at the System

Information tab in the Machine menu.
:
Example of version number:
V 1.2.3
V stands for version
V 1.x.x is the major version number
V x.2.x is the minor version number
V x.x.3 is the update version number

The major version number is increased when new major features are
added to the software. These software changes require additional
introduction and could change the normal working order. The minor
version number is increased when new features and enhancements
are integrated which do not change the working order. The update
version number solely is used for software changes when
corrections are needed in the existing software version.
2. Products, the product library
2.1. Introduction

In the Products mode existing, previously produced, products can be

selected to start production or for modiOcation in order to make a
similar product. To start making a new program New Program can be
used from this mode.
2.1.1. The main view
:
In Products mode an overview is given of the program library on the
control. In this mode a product program can be selected (loaded).
After that a program can be modiOed or executed.
Each item in the list consists of its Product ID, the Product

4.2.1. Bend parameters

Method
Select the required bending method. The control supports the
following standard methods:
air bend
bottoming
hemming
hemming & bottoming
Bend methods
:
Note 1: The hemming bends are shown here with a special hemming
punch, but this is not required.
Note 2: When bottoming operation is selected, the end of bend
position of the Y-axis beam depends on the working force. If however
the force is suzcient for the beam to go to the calculated Y-axis end
of bend position, the beam stroke will be limited by the position
value.
Bending length
Length of the sheet between tools.
Effective bend length
The effective length of the sheet between tools, which is used for the
calculation of the force and the crowning device (if present). This
effective bend length is calculated from the product geometry; for
additional bends and simultaneous bends this calculated value is the
:
additional bends and simultaneous bends this calculated value is the
sum of the separate bend line lengths.
Product position
The absolute position value of the product in the Z-direction. Left
machine side is reference position zero.
Angle
The required angle of this bend. This parameter only appears if angle
programming is selected with the parameter ‘Angle sel.’ and the bend
method is an air bend.
Hem opening
The hem bend can be made with a certain opening distance between
the 2 {anges. The hem opening value will be used calculating the
beam position in the hemming process.
By default this parameter has the value of the Settings mode
parameter Default Hem Opening.

Y-axis (Bend position)

The required Y-axis position for this bend. This parameter only
appears if absolute programming is selected with the parameter
‘Angle sel.’ This parameter also appears if the bend method is
bottoming and/or hemming.
Mute
Sequence point at which the Y-axis is switched from fast closing
speed to pressing speed. The value programmed here is the distance
of the mute point above the sheet.
By default, the mute value from the programmed die is used. Whether
or not this parameter is present depends on machine settings.

Parallel
Difference of left- and right hand side cylinder (Y1 and Y2). When
positive, right hand side lower. When negative, right hand side higher.
The programmed value is active below the clamping point.
:
The programmed value is active below the clamping point.

Opening
This parameter results in a certain gap opening between the punch
and the die after the bend. A positive value is the gap opening above
Mute, a negative value below Mute.
When you want to limit the handling time of the product you can
program a small positive or a negative value.

4.3.2. Change tools

To change the tools the Tool Setup menu can be used. If the tool
setup needs to be changed for just one bend step, the Change Tools
button can be used. The control will always ask if the changes are to
be done on the whole setup or just for one bend. If the whole tool
setup is required, automatically the Tool Setup menu will be switched
to.
4.3.3. Product properties

To change the main product properties tap Product Properties. These

parameters of the program are the same for every bend of the
program (main data of program).
4.3.4. Add bend

By tapping the navigation button Auto the control is switched to the

automatic production mode.

In auto mode with the active program, production can be started.

After entering Auto, the Start button can be pressed and production
can begin.
:
can begin.

The automatic mode executes the program automatically bend by

bend after pushing the Start button. When selecting a different
product in Products mode, which is in the library and has already
been used for production, one can immediately switch to Auto and
start production. Every time after a different bending program is
selected you must check your tools and tool positions in your
machine. This is also indicated with a ‘check tools’ warning message
when you enter the automatic mode.
In the header of the Auto mode screen the selected product is
displayed along with the product description. At the top of the screen
the bend selector shows the available bends in the program. By
tapping the prefered bend the bend can be selected. The start button
:
tapping the prefered bend the bend can be selected. The start button

The repetition of a bend and the connected programs, when
applicable, are shown in the header of the screen. A connected
program is also indicated in the bend selectors last position.
5.1.1. Auto mode, parameter explanation

Following is a list of the available parameters in Auto mode.

5.2. View modes

The auto mode screen is offering a diversity of views which,

depending on ones production methode, can be chosen. When
selecting auto mode for the Orst time, the main screen will appear. On
the right side of the screen the available view modes can be selected.
Following view modes are available:
:
The appropriate view can be switched from and to, not changing the
bend data. The Start will not jump to Stop while switching view
modes.
5.2.1. Main

Main view shows the numerical data of the bend along with the
corrections. The corrections can be programmed here.
:
Both columns can be scrolled to see all data.
Bend selector
The bend selector in the top of the screen can be used to navigate
thru the bends. The indicated bends can be tapped to easily select
the desired bend data.
5.2.2. All bends

The all bends view mode shows a table including all bend data. The
bends are shown row wize and the columns display all bend
parameters.
:
5.2.3. Macro

With macro view mode, the control switches to a view with only large
axes values on the screen. This view can be used when working a
little remote from the control, still able to read the axes values.
:
Next to the target position (programmed) also the actual position of
all axes can be followed.
5.2.4. Manual positioning

In manual positioning view mode the axes values are shown at large.
Axes can be selected and while selected the position can be
controlled by moving the slider, on the bottom of the screen, out of its
middle position. When releasing the slider it will return to its middle
position automatically.
The teach indicator:

When the teach indicator arrow is pressed, standing in between

actual value and programmed value, the value is tought to the
program step.
5.2.5. Corrections

In this view mode all corrections of all bends are shown. You can
browse through all corrections and change them as you see Ot. If a
correction for α1 is entered then this value is, dependent on the
settings parameter ‘Angle correction programming’, copied to the
correction for α2, or keeping the delta between both corrections, or
not in{uencing the correction for α2. Different corrections for α2 can
be entered in the Oeld itself.

The column ‘Stored correction’ is only available when the Angle

correction database has been activated. When activated, the column
‘Stored correction’ shows for each bend the correction value that is
present in the database. A blank entry in this column means the
database does not have a correction value for this type of bend.
When a new correction is entered, it will be copied to the database
:
When a new correction is entered, it will be copied to the database
automatically.
The markers ‘>’ indicate bends that have the same value.
All From Stored serves to copy corrections in the database to the
current program: corrections in all bends are adjusted according to
database values.
Calculate corrections, programming of measured angles
To calculate the corrections from measured angle values, one can
use the “calculate corrections” function in the correction window.
Calculate corrections will open a separate window in which, upon
choice, the measured angle(s) can be programmed.

From the programmed value the control will determine a correction.

The proposed result can be seen in the window itself. In the top of
the window the programmed angle is shown, in the bottom of the
window the resulting corrections are shown. When selecting accept,
these values will be transferred to the main corrections screen.

When only one measured angle value is entered, the other values will
be copied equally. If there are separate left, right or even middle
values, these can be entered as well. The appropriate correction
values will be determined from the entered values. The middle
measured angle, if applicable, is transferred to an absolute crowning
correction.
Axes corrections can also be edited in the main screen. When there
are multiple axes available this special view mode can be switched to
for all axes corrections.
5.2.6. Diagnostics

The diagnostics view mode is meant for service purpose mostly. In

diagnostics the activities of independent axes can be monitored. I/O
on the control system can be followed. In rare situations this
information can be helpful to diagnose operation during the bending
:
information can be helpful to diagnose operation during the bending
proces.
5.3. Bumping correction

In case of a selected bumping bend a general correction for a

bumping bend can be entered. This function is only available if a
product is loaded that contains a bumping bend.
With Bumping Corr. a new window appears in which the correction
can be entered.

When the general correction of an angle is altered, all individual

corrections are recalculated. When any of the individual corrections
is altered, the general correction is recalculated.
Bumping corrections can be programmed independently for both
sides, α1 and α2.

If a bumping correction for α1 is entered then this value is, dependent

on the settings parameter ‘Angle correction programming’, copied to
the bumping correction for α2, or keeping the delta between both
bumping corrections, or not in{uencing the bumping correction for
α2. Subsequently all separate corrections for α2 are recalculated. To
change correction values of α2, use bumping correction α2 or one of
the separate corrections of α2.
6. Manual mode
6.1. Introduction

By tapping the navigation button Manual the control is switched to

the manual production mode.

In manual mode you program the parameters for one bending. This
:
In manual mode you program the parameters for one bending. This
mode is useful for testing, for calibration and for single bends.

Manual mode is independent from Automatic mode and can be

programmed independently of the programs in memory.
In the top of the Manual mode screen you can Ond the Y-axis and the
main X-axis current position. All other axes and functions are listed
one by one in the two columns below.
When these Y-axis value and X-axis value are highlighted it means
that the reference markers of these axes have been found and that
they are positioned correctly referred to their programmed values.

Method
Select the required bending method. The control supports the
following standard methods:
Air bend
Bottoming
Hemming
Hemming & bottoming

The bend methods have been explained in more detail in the Program
mode.
Bending length
Program the bending length of the sheet.
Product position
The absolute position value of the product in the Z-direction. Left
machine side is reference position zero.
Angle
Angle to bend.
Corr.α 1, Corr.α2
:
Corr.α 1, Corr.α2
Correction on angle to bend.
The angle correction should be entered as following examples
indicate:
Programmed value of 90 degrees.
Measured value of 92 degrees.
-> Then it is required to program Corr. with -2.
Programmed value of 90 degrees.
Measured value of 88 degrees.
-> Then it is required to program Corr. with +2.
Hem opening
The hem bend can be made with a certain opening distance between
the 2 {anges.
The hem opening value will be used calculating the beam position in
the hemming process.
By default this parameter has the value of the Settings mode
parameter Default Hem Opening.

Corr.Y
Correction on the Y-axis position, in case bottoming has been
selected.
Y-axis
The programmed or calculated Y-axis value to realise a certain angle.
Mute
Sequence point where the Y-axis is switched from fast closing speed
to pressing speed. It is programmed here as a Y-axis position value.
The programmed value is the Y-axis point above the sheet.

Parallel
Difference of the left- and right hand side cylinder (Y1 and Y2). When
positive, the right hand side is lower. When negative, the right hand
side is higher. The programmed value is active below the clamping
:
side is higher. The programmed value is active below the clamping
point.

Opening
This parameter results in a certain gap opening between the punch
and the die after the bend. A positive value is the gap opening above
Mute, a negative value below Mute.
When you want to limit the handling time for the product you can
program a small positive or a negative value.
Force
Force
The programmed force applied during pressing.
Dwell time
Hold time of punch at the bending point.
Decompression
Decompression distance after the bending to release the working
pressure from the system.

Speed
Speed

Decomp speed
The decompression speed is the programmable speed of the beam
during the decompression distance.
Functions
Wait for retract
In case of a retract, let the Y-axis wait until the retract is Onished, yes
or no.
No: the retract is started when the Y-axis passes the clamping
point, the Y-axis does not stop.
:
 point, the Y-axis does not stop.
Yes: when the Y-axis reaches the clamping point, the Y-axis is
stopped and the retract is started. When the retract is
completed, the Y-axis moves on.
Product properties
Thickness
Program the thickness of the sheet.
Material
Selection of one of the programmed materials, which are used to
calculate the bending depths. The control contains 4 pre-
programmed materials. In total, 99 materials can be
programmed on the control. The materials can be programmed
on the Materials page in the Setting mode.

Tools

the punch library.
Die
The name (ID) of the selected die. Tap to modify or select from the
die library.
Auxiliary axes
Auxiliary axis
If you have one or more auxiliary axes (for instance an X-axis, R-axis
or Z-axis) the parameters of these axes appear here.
Retract
The retract distance of the axis during the bend. The “backgauge
retract” is started at the pinching point.
Speed

percentage of the maximum possible speed.
:
percentage of the maximum possible speed.
The above mentioned parameters can be programmed and modiOed
as required. After pushing the Start button the programmed
parameters are active.
6.1.2. Tool setup

The programming of the tool setup in Manual mode is similar to

programming the tool setup which is used in Automatic mode.
Despite the fact that both modes do not share the same tool setup
(enabling the usage of a complete different tool setup), the tool setup
of Automatic mode could be used in Manual mode as well.
While switching from Automatic mode to Manual mode, the control
offers the user to use the same tool setup in Manual mode and thus
also the user is warned that in case differently programmed, one
should be careful.

In the tool setup menu tools can be added or removed, similar to the
main Tool Setup mode as described in chapter 3.
Adding tools ( Punches / Dies )

Same as in Tool Setup, via the Add function tools can be added.
6.2. Programming parameters & Views

Parameters in manual mode can be programmed one by one. The

effect of the parameter on other parameters is automatically
computed.
The relation between parameters is visualized with a symbol and a
background color.

When an information symbol is shown with parameters after an

editted value, this parameter was changed due to the last changed
input.

A star symbol is shown with parameters if the value of the parameter

differs from the calculated value by the control. This can be helpful if
a value is intentionally programmed different or if the value of a
:
a value is intentionally programmed different or if the value of a
parameter is limited by the parameters limits.

An error symbol is shown with parameters if the value cannot be

correct according to the currently programmed values. This, eg. when
a hemming bend is programmed with no hemming tools
programmed.

View
The command buttons on the right side of the screen give access to
other views. Next to the Main view, there are Macro, Manual
Positioning, Corrections as also a Diagnostics view.
6.3. Macro

With Macro the control switches to a new view with only large axes
values on the screen. This view can be used when working a little
remote from the control, still able to read the axes values.
6.4. Manual movement of the axes
6.4.1. Movement procedure

To move an axis to a speciOc position manually, the slider at the

bottom of the screen, can be used. After tapping Manual Pos in the
main screen of Manual Mode, the following screen appears:

Within this mode, any of the shown axes can be moved by moving
the slider out of its middle position. The procedure for moving the
axis depends on the axis you wish to move. When releasing the slider
it will automatically return to its middle position.
Auxiliary axes
The control must be stopped (the Stop button is on).
First select the desired back gauge axis, you will see the cursor at the
required axis.
Then you can move the axis by moving the slider.
Y-axis
The pressbeam can be positioned manually in the same way as the
:
The pressbeam can be positioned manually in the same way as the
auxiliary axes.
However, for the Y-axis several conditions must be met:
The control must be started (the Start button is on).
The ‘adjust’ function must be active. If this function is not active
a message is
shown in the upper right-hand corner.
The Y-axis must be below mute-point.
A pressing command must be given to the CNC.
6.4.2. Teach

To teach the control, taking over a position found by manual moving

an axis, a simple procedure can be used.
When you have moved an axis to a certain position with the slider,
you may want to store this position. To do so, tap the axis name in
the Programmed column. The actual axis value (left side) will appear
in the programmed axis Oeld (right side).

When you return to the standard screen of manual mode, the axis
parameter will have the recently taught value.
6.5. Corrections

In this view mode the corrections for the bend programmed in

Manual mode are shown. Since this is always a single bend, a single
line will be shown.

The programmed corrections can be veriOed here similarly to the

corrections in Automode.
Entries in the correction database and for initial correction can also
be monitored in this screen. Since these are of signiOcant in{uence
on the bend result, access to the database can be used to modify.
This can also be useful while Onding appropriate corrections with
testbending and storing the found results in the database.
6.6. Diagnostics

When tapping Diagnostics, the control switches to a view which

:
When tapping Diagnostics, the control switches to a view which
shows axes states. In this window, the current state of available axes
can be observed. This screen can also be active while the control is
started. As such, it can be used to monitor the control behaviour
during a bend cycle.
6.6.1. I/O status

When tapping on the I/O tab in the Diagnostics, the control switches
to a view with the state of inputs and outputs. In this window, the
current state of inputs and outputs can be observed.
This screen can also be active while the control is started. As such, it
can be used to monitor the control behaviour during a bend cycle.
6.6.2. Zoomed I/O

When tapping on one or more (up to 5) pins an extra page Zoomed IO

is created with an enlarged view of the selected IO; selected pins will
be shown in large, enabling distant monitoring.

7. Settings
7.1. Introduction

By tapping the navigation button Settings the control is switched to

Settings mode.

The Settings mode of the control, which can be found in the

navigation panel, gives access to all kind of settings which in{uence
the programming of new products and programs.
Default values and speciOc constraints can be set.
The settings are divided across several tabs logically organizing the
different subjects. In the following sections the available tabs and
detailed settings are discussed.

Navigation through the tabs can be done by just tapping them and
selecting the required item to adjust. Since there can be more tabs
than the screen can show in one view, dragging the tabs in horizontal
direction enables to view and select all available tabs.
:
direction enables to view and select all available tabs.
7.2. General

Select the required tab and tap the parameter to be changed. When
parameters have a numerical or alphanumerical value, the keyboard
will appear to enter the desired value. When the setting or parameter
can be selected from a list, the list will appear and selection can be
done by tapping. Longer lists allow scrolling vertically to check the
available items.
Inch/mm-select
Select to use either millimeters or inches as the unit to be used.
Ton/kN select
Select to use either Ton or kN as the main unit to be used for all force
data.
Resistance per m/mm selection
Select to use the resistance either per meter or per millimeter.
Language
The user interface language can be selected from the list. There are
more available languages than initially shown. Scroll vertically by
dragging the list up en down to see all available languages. Tap to
select the desired language for the user interface.
(For languages using special, non standard alphanumerical
characters, the control will reboot.)

Keyboard layout
Upon choice one can select Qwerty, Qwertz or Azerty keyboard
layout.
Key sound
Switch the sound function of the input panel on or off.
Message sound
Parameter to enable/disable the sound function for messages
dependent on the message type.
:
dependent on the message type.
all messages => sound on for all messages.
errors + warnings=> sound on for errors and warnings only.
errors => sound on for errors only.
none => sound off for all messages.
Command panel side
Switch the command panel to the left side of the screen.
7.3. Materials

In this tab, materials with their properties can be programmed.

Existing materials can be edited, new materials can be added or
existing materials deleted. A maximum of 99 materials can be
programmed on the control.

For each material 3 properties are present and can be viewed and
edited.
Material name
Name of the material, as it will appear in the programming
screens. The maximum allowed length of the material name is
25 characters, the name must begin with a character (not a
numeral).
Tensile strength
Tensile strength of the selected material.
E module
E-module of the selected material.
Strain hardening exponent
The Material strain hardening exponent, n, is a material property
that should be provided by the supplier of the material, just like
the tensile strength and E-module.
Entering the correct values for this parameter will give an
improvement of the inner radius calculation and thus a more
accurate bending depth and bend allowance calculation.
In its turn a more accurate bend allowance will result in more
accurate back gauge positions.
:
 accurate back gauge positions.
Initially the value is set to _.__ for all the materials. This means
that the parameter n is not active. The result of all calculations is
the same as with previous software versions.
The range of the parameter n is 0.01 – 1.00.
For example, a typical value for mild steel is 0.21.
When 0 is entered again, the value will be reset to _.__
Calculate n
The Material strain hardening exponent, n, is a material property
that should be provided by the supplier of the material, just like
the tensile strength and E-module.
As an alternative, it can also be derived from the bend
allowance. A test bend has to be made in Manual mode. When
you switch to the materials table and tap the button ‘calculate n’,
the following window will appear on the screen:

The parameter values are taken from the Manual mode screen. After
the bend the resulting side length should be measured and entered in
the window. With the difference between the programmed X-axis
position and the measured side length the bend allowance and the
strain hardening exponent (n) are calculated.
The accuracy of the calculation depends on the accuracy of the
sheet thickness, tool parameters and side length measurement.
The materials are initially listed according to their material number,
which is shown in the Orst column (ID). The list can be sorted
according to the different properties by tapping the title of the
column. The materials will be sorted in ascending or descending
order of that property.
To change an existing material, select the relevant line and change
the values as you see Ot.
To delete an existing material, select the relevant line and use Delete
Material. This will erase the values.
To program a new material select an empty line and start
:
To program a new material select an empty line and start
programming its values.
7.4. Backup / restore

This tab offers the possibilities to backup and restore products, tools
as well as settings and tables. When products or tools originate from
older control models, the DLC-Ole format products and tools can also
be restored using this speciOc restore function.
For materials a speciOc backup and restore are available here.
Tools and products can be backupped and restored according to the
following procedures.

The procedures for saving or reading data are similar for all types of
backup media: e.g. network or USB stick.

The actual backup directory consists of a device (USB stick, network)

and a directory.
The choice of devices depends on which devices have been
connected to the control.
If necessary, directories can be created and selected. The backup
locations for storage of products and tools can be set independently.
7.4.1. Product backup

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.
Basic functions to change the view can be chosen similarly to the
Products mode.
This enables to easily Ond the required products to be backupped.
:
This enables to easily Ond the required products to be backupped.
At the top of the screen, the current source location is shown as well
as the backup location.
To backup a product, select it by tapping, in the list. The backup
marker will appear to conOrm the backup action. If a product Ole with
the same name is present on the backup location, a question is
offered whether or not to replace that Ole.
To backup all products at ones, tap All.
The source where the products are located which have to be
backupped can be changed with Source Directory. The directory
browser appears and the desired source directory can be navigated
to.

The directory where the products which need to be backupped need

to go can be changed as well. With Backup Directory the directory
browser appears and the desired destination directory can be
navigated to.
7.4.2. Product restore

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.
Basic functions to change the view can be chosen similarly to the
Products mode.
This enables to easily Ond the required products to be restored.
At the top of the screen, the current restore source location is shown
as well as the location on the control to restore to. To restore a
product, select it by tapping, in the list. The restore marker will appear
:
product, select it by tapping, in the list. The restore marker will appear
to conOrm the restore action. If a product Ole with the same name is
present on the control, a question is offered whether or not to replace
that Ole.
The source location where the products to be restored are coming
from can be changed with Restore Directory. The directory browser
appears and the desired restore directory can be navigated to.
The directory where the products which need to be restored need to
go can be changed as well. With Destination Directory the directory
browser appears and the desired destination directory can be
navigated to.
7.4.3. Tool backup

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 backup.
7.4.4. Tool restore

The restore procedures for tools run similar to the procedures for a
product restore.
7.4.5. Backup and restore for Tables and Settings

To backup user speciOc settings and tables the Backup/restore tab

offers speciOc functionality. The procedure is again similar to the
backup and restore of products and tools.
The special function All will automatically execute all steps
sequentially for either Backup or Restore (Products + Tools + Tables
+ Settings).
7.4.6. Directory navigation

When Backup Directory is used, a new window appears with a list of

:
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.
To change from one device to another, tap the highest level, and from
there select the proper device and choose the correct subdirectory.
If a network connection is available you must Orst select Network
and subsequently one of the offered network volumes. After that it
works similar to other devices.

You can make new subdirectories or delete existing ones by tapping

Make Subdir and Remove Subdir. If there are subdirectories present,
just tap it to move to the required directory and tap Select to select it.
7.5. Program settings

Angle correction database

Parameter to enable the database with angle corrections.
Angle corrections are entered in production mode (Automatic mode).
These corrections are stored in the product program.
The Angle correction database enables the possibility to store these
corrections in a database. In this way corrections that have once
been entered for certain bends remain available for future use in
other products.
With this setting enabled, the control checks during production
whether corrections for similar bends are present in the database. If
corrections for certain bends are available, then they will be offered.
On other occasions, corrections can be interpolated and offered.
The correction database is adjusted by entering new corrections
during production.
When the database is enabled with this parameter, all new-entered
:
When the database is enabled with this parameter, all new-entered
corrections are stored in the database.
When searching for similar bends, the control searches for bends
that have the same properties as the active bend. The following
properties of a bend are compared:
Material properties
Thickness
Die opening
Die radius
Punch radius
Angle
The Orst Ove properties of a bend must be exactly the same as the
active bend to start a comparison. If the angle is the same as the
angle of the active bend, the correction is offered. If the angle of the
active bend has a maximum difference of 10° with two adjacent
bends, a correction is interpolated from these two bends. If the
difference of the corrections of the two adjacent bends is more than
5°, there will be no correction offered.
Initial angle correction
To program relative small angle corrections the initial correction
database is available.
This parameter is independent on the parameter “Angle correction
database”.
The initial correction is only visible and programmable on the
corrections page in Automatic mode and Manual mode. On the main
page in Automatic mode and Manual mode the initial correction is
not visualized. The total correction is the sum of the visualized
correction and the initial correction.
Example:
– Program an angle correction of -8 degrees.
– Program an initial correction of -6 degrees. Now the total
:
correction remains unchanged: the visualized correction is changed
from -8 degrees to -2 degrees.
disabled => no initial angle corrections programmable.
enabled => initial angle corrections programmable on the corrections
page
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 speciOc 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 C 2 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.
:
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.
Machine ID
When there are several bending machines in a factory, it can be
useful to give the control on each machine a unique machine ID.
This ID will be checked when a program is read from a back-up
medium. When the machine ID does not match you must conOrm to
read it anyway or not. If you do not conOrm the question the action
will be aborted.
Machine ID check
When a product from a machine with a different machine ID is
selected, a warning will appear on the screen. With this parameter
this check can be disabled.
Machine description
The description as programmed here will only be used in the oÇine
ProOle-T to get an overview of the different machines available in the
factory. With this information it will be more clear which machine is
used in combination with this control.
7.6. Default values

Y opening default
Default Y-axis opening, used as initial value for the parameter
‘opening’ in a new
program.
Default pressing speed
Default pressing speed, used as initial value for the parameter ‘speed’
in a bend program.
:
in a bend program.
Default decompression speed
Default decompression speed, used as initial value for the parameter
‘decompression speed’ in a bend program.
Default wait for retract
Default value for the parameter ‘wait for retract’ in a bend program.
This parameter determines the control behaviour in a bend program.
Default step change code

Default value for the parameter ‘step change code’ in a bend

program. This parameter determines the moment of step change in a
bend program.
The step change codes have been explained in more detail in the
Program mode.
Default delay time
During the postprocessing, the waiting time of the X-axis at step
change is set to zero.
With this parameter you can preset a longer waiting time when
needed for product handling.
Default dwell time
Default value for the parameter ‘dwell time’ in a bend program.
Default hem opening
The hem bend can be made with a certain opening distance between
the 2 {anges. The hem opening value will be used calculating the
beam position in the hemming process.
This programmed default value will be used when programming a
new program in the Program mode. The starting value is 0.0mm to
get the two {anges of a hem bend completely upon each other
without any space between the {anges.
:
Default material
Default material, used as initial selection while starting a new
program.
7.7. Computation settings

Data preparation bend allowance

correction off => no bend-allowance added to numerical
programming
correction on => bend-allowance correction added to numerical

programming
With this parameter you can choose whether or not you wish to have
programmed values corrected for bend-allowance. This setting only
refers to corrections during product programming in the Program
mode. If a numeric program has been entered with Corrections On,
the axis corrections are calculated and stored in the program. These
corrections can be viewed and edited inproduction mode (see ‘Auto
mode’).
Bottoming force factor
The force needed for an air bend is multiplied by this factor in order
to obtain the bottoming force.
Z-distance
The distance from the edge of the Onger to the corner of the sheet.
When an automatic Z-axis has been installed, the positions of the
Ongers are calculated automatically with respect to the end of the
sheet.
7.8. Production settings

Stock count mode

Setting for the stock counter in production mode, to have the stock
counter (product counter) count up or down.
When down counting is selected, the stock counter in production
:
When down counting is selected, the stock counter in production
mode is decremented after each product cycle. When the counter
has reached zero, the control is stopped. On the next start action, the
stock counting value is reset to its original value.
When up counting is selected, the counter is incremented after each
product cycle.
Down counting can be useful if a pre-planned quota must be
produced. Up counting could be used to give a report on production
progress.
Auto bend change mode step

This parameter can be used to have automatic step change in the

bending process with the Step mode enabled.
disabled => No automatic step change (next bending parameters
active) will take place. To perform the next bending you must select
the new bending and press the start button.
enabled => The next bending parameters are loaded automatically
but the axes will start positioning after the start button has been
pressed.
Parallelism offset
An overall parallelism, valid for the complete Y-axis stroke, can be
programmed with this parameter. The programmed value will be
checked against the maximum allowed value during production. The
parallelism which can be programmed for each bending (Y2) is only
active below the clamping point. The parallelism below the clamping
point is the sum of the two parameters (Y2 + Parallelism offset).
Lock touch screen when started
To enable the locking of the touch screen while the control has been
started.
Pressure correction
Percentage of calculated force which actually controls the pressure
valve.
:
valve.
Clamping correction
The position of the beam at which the sheet is clamped, is
calculated. In order to have a Orm clamped sheet it is possible to
offset the calculated pinch point with the value here programmed. A
positive value will result in a deeper position, a negative value in a
higher position of the beam.
X-safety offset

DeOnes the safety zone (minimum X-axis value), following the

contour of punch and die, which will be used in case a R-axis is
mounted. This to prevent collision between Onger and punch / die.
Intermediate X for Z-movement.
Temporary safe value for the X-axis, to avoid collision as a result of
movement along the Z-axis. With this parameter a standard safety
zone for the X-axis is deOned, which is valid for all programs. The
value 0 disables this functionality. This parameter should not be
confused with the parameter ’X-safety offset’.
This parameter is especially useful when several dies of different
sizes are placed on the machine. In that situation, this intermediate
X-value should be larger than the safety zone of the largest die that is
installed.

When the back gauge has to move to a different Z-position, it is

checked whether the current X-position is safe. We can distinguish
the following situations:
Old X-axis position as well as new position outside the zone: X-
and Z-axis movements happen at the same time, no change.
Old X-axis position outside, new position inside the zone: back
gauge is positioned on Z-axes Orst, the X-movement starts when
the Z-axes are in position.
:
 the Z-axes are in position.
Old X-axis position inside, new position outside the zone: back
gauge starts along Xαaxis, Z-movement is started when X-axis is
outside the zone.
Old X-axis position as well as new position inside the zone: back
gauge moves to the intermediate X-axis position, then the Z-
movement is started. When the Z-axes are in position the X-
movement is started to move the back gauge to its new position.
Intermediate R for X-movement

Temporary position for the R-axis, to avoid collision as a result of

movement of the Xαaxis. The value 0 disables this functionality.
When programmed not equal to zero this position will be active when
the X-axis has to move inside the safety zone of the die.
7.9. 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.
