This manual describes the operation of the Delem controller type DA-56 and is meant for
operators who are instructed for operation of the total machine.
Only authorised people should be able to create new or edit existing programs, as well as programming or editing of the tooldata. Therefore the controller has a keyswitch to prevent
uncontrolled programming. With the keyswitch in the off position the operator can only execute a selected program. The operator cannot change the parameters to wrong, unwanted values.
Version history
The control software is updated regularly to increase performance and add new functionality.
This manual is also updated as a result of changes in the control software. The following overview shows the relation between software and manual versions.
The precise outfit of your control may vary.
Operation of the control is done with the various keys on the front panel. A description of all
keys and their functions is given in the next section.
Beside the front panel keys, an external USB mouse can be used as a pointing device to select
menu items, parameters or softkeys. It depends on your configuration whether such a device is
available. In this manual the phrase ‘mouse’ is used to describe any of these possible pointing
devices.

1.5.Graphical programming
From the main menu you can select one of the programming possibilities.
In order to design or edit a new product, the graphical programming facility is present.
This facility is a complete product design tool that allows you to draw the profile of your product. It consists of a machine-and tool-library which allows you fast automatic, interactive or
manual bending sequence computations with display of possible product/tool/machine collisions and developed length.
The graphic design tool provides a way of selecting the most optimal bend sequence for a
product, keeping in mind the minimum production time and manipulation possibilities of the
product.
Features of the design tool
-Graphical design of product shapes in 2D
-Auto scaling
-Horizontal and vertical projected dimensions can be entered
-Blank length computation
-Real scale tool design
-10 different upper side shapes and 10 different under side shapes (tables)
-Changing of lengths and angles
-Bumping (big radius)
-Adding or deleting of bends
-Existing products can be copied, changed and stored as a new product
-Production time indication
-Closing dimension or highest precision tolerance selection
-Connecting 2D programs for 3D-production

In case you are drawing the profile of your product or tools the cursor keys can be used to give
directly multiples 45 degree angles. e.g.:
a = 135°
a = 45°
a = -90°
a = 90°
-Horizontal or vertical projections for 2D-products
After you entered the length of the line interval you can specify if this line interval is either the
nominal length, horizontal or vertical projection. The given length dimension in the enter field
is the line length L if the drawing cursor is in the concerning line.

2.Product drawing/Product edit for 2-dimensional products
2.1.Introduction
1.To start a new product drawing, choose product drawing in the
main menu.
2.To edit an existing product drawing, choose product edit in the
main menu.
On this page you have to enter first the product number and then the drawing number. The
drawing number may also contain alphanumeric characters, which can be entered with the help
of the function key ‘alphanum’ (S6).
A name or description of this program. The maximum length is 20 characters.
If an existing product number is entered, a warning appears that this product already exists.
You are asked whether to replace that existing product with the new product or not. If you
choose ‘yes', the existing product is erased. If you choose ‘no', you must enter a new number.
The "±" key prompts a "-" character and the "." key prompts a "/" character in the drawing
number.
V0606, 2.1
Page 22
After finishing this input you have to enter specific product data. Then you can start drawing
the product.
In the edit mode you also have the possibility to make a copy of the active product. A special

You create now the bending profile of the product. First you enter the value of the basic length
of the product. Then you enter the angle of the next side followed by the length of that side.
This procedure continues until the product has the desired profile. A circle indicates the actual
position. With the cursor control keys you move this circle to an other position (angle or
length). During the drawing of the profile of the product the graphical software always displays the product at relative scale.

2.2.Delete an angle/line or insert an angle
The function of softkey (S1) depends on the position of the drawing cursor.
-If the cursor is within a line segment, it is possible to insert a new angle to bend, in combination with the enter key.
-If the cursor is positioned on a bend, it is possible to delete that bend.
-If the cursor is at an end line of the product, the line can be deleted.
2.3.Precision selection
When the drawing cursor (small circle) is on a line segment, with S2 high precision or closing
dimension can be selected. With S2 these functions will be toggled giving 3 possibilities (high
precision - closing dimension - normal situation).
2.e
- High precision:
At bend sequence computation the backgauge stop position will be chosen to get the highest
possible precision of this line interval.
- Closing dimension:
At bend sequence computation the backgauge stop position will be chosen to get the resulting
tolerances in this line interval.
V0606, 2.5

Line interval marked with the open circle should be, if possible, directly placed between back
stop and the centre of the die.
Notes:
Specifying line intervals with high precision and closing dimensions may result in longer production time.

2.4.Large Radius: Bumping
To make a bend with a large radius, the control uses the bumping method. With this method, a
large radius in a product is obtained by a series of slight bends in succession.
2.g
To program such a bend, you must program the following parameters:
radius = the desired radius
segments = number of segments
The number of bends in this radius is the number of segments plus 1.
The more segments you select, the more bendings will be used to create the programmed
radius within a smaller tolerance. With a high number of segments you will need a smaller Vdie opening to be able to bend in a proper way. Which value is acceptable as maximum for the
V-opening of the die is calculated and displayed on the screen.
For the definition of the line lengths to be programmed in the part connected to a bump radius
segment, see figure 2.h.
2.h
Lengths L1 and L2 must be equal or bigger than the radius R.
When you must program such a bend, first program a standard angle with adjacent sides. Then
put the cursor back on the angle and press the function key ‘bumping’ (S2). You will be
prompted to program the radius and the number of segments. After programming these parameters the radius is drawn in the product and the maximal V-opening which can be used is displayed on the screen. This is shown in figure 2.i.
V0606, 2.7
Page 28
2.i
Specification items:
Radius input:
min. value = 0.1 mm
max. value = 2500.0 mm
In the ‘assignments’ menu, it is possible to modify the way the radius bend is divided into segments. See section 2.5 for more information.
2.5.Assignments
Pressing ‘Assignments’ results in the parameter pages.
If Variants programming is active (indication 'Variants On' in the title bar), a warning is given
that corrections will be lost. Press 'Yes' to proceed with the assignments or 'No' to go back to
the edit screen.
See section 2.8 for more information about variants programming.
Some of these parameters are machine related, axis speeds a.o. and some are related to handling possibilities and turn times.

2.j
To load default assignment settings. It is possible to
determine a set of assignments which have the most optimal values to work within your surrounding. This set can
be stored into the internal memory by pressing softkey S4
(save as default). While programming another product
you can recall this previous fixed set by loading the values via softkey S3.
This parameter (mm) is usefull in case the pressbrake has been equiped with backgaugefingers on a moving R-axis, having a so-called “lay-on” construction.
When the length of the plate at the backside of the machine is greater than this limit, the
X-axis and R-axis positions will be corrected automatically so the plate will rest on the
backgauge finger. (0 - 3200.0 mm)
This is only possible if an automatic R-axis is enabled.
2.k
After postprocessing, the controller calculates the developed length of your product and the
bend allowance.
Important for the developed length calculation and the bend allowance is the inner radius of
the bends.
For each of these computations a correction factor can be programmed (RF and AF).
The computed inner radius is multiplied by this factor to correct the X-axis position in
order to have a correct product dimension after each specific bend (bend allowance).
This factor can be checked by making a product with just one bend and a certain product
dimension e.g. 100 mm (outer dimension). See figure 2.s.
The controller computes the X-axis position necessary to obtain L=100 as shown in figure 2.s.
The accuracy of the length L is dependent on the material parameters like thickness, strength
and kind of material. In order to have a correction possibility with the radius factor AF you can
optimise this computation.
RF and AF do not influence each other. It is recommended that first you optimise the AF factor
for your product and thereafter find the correct value for the developed length correction RF.
During postprocessing of the programmed product, the control always computes an optimal opening of the pressbeam to handle your product. Here you can program a minimum
required opening. The programmed value is the distance above the speed change point
MUTE.
For the calculation of the developed length and bend-allowance during the postprocessing of a graphical 2D product, a Delem formula is used. It is also possible to select the
standard DIN-formula (DIN6935).
0 = Delem formula (OFF)
1 = DIN formula (ON)
Default setting is zero for the Delem formula. Press the key to select the required setting.
When a product has a radius bend, the segment size is computed from the number of segments, which has been defined by the user. Standard the first and last segment are calculated half the size of the mid segments to obtain a better result. However, it can be a
problem selecting a die suitable to bend these small segments. Therefore the control can
calculate an equal size for all segments. This can be defined with this parameter.
0 = disabled (no equal sizes)
1 = enabled (equal sizes)
Press the key to select the required setting.
When this parameter is set to 1, all segments will have an equal size.
If it is set to 0 the calculation is as before, including half size segments. If in this case a
problem with the size of the V die is detected in the bend sequence menu, the user is
asked whether or not to select a re-calculation with equal size segments.
2.6.Bend sequence
After completion of your drawing, with function key S5 you select the "bend sequence" mode.
You will have to enter the number of the machine lowerside, the die, the machine upperside
and the punch first. This number corresponds with the number in the respective tool libraries
(menu number 7, 8, 9 and 10).
If the number entered is not known, the controller prompts the message "not programmed".
You have to program the machine parts and tools before you can compute the bend sequence.
Programming can be done via the respective selections in the program menu. The several tools
as available in the respective tool libraries can be shown on the screen with S2 (show library).
V0606, 2.11
Page 32
This selection will give an overview of the tools including the main properties of each tool.
2.m
In your machine and tool library you can program 1 machine uppersides, 1 machine undersides
(tables), 30 different dies and 30 different punches. One of each must be selected, and can also
be changed during the bending sequence determination. These selections are prompted in the
lower left corner of the screen. Within the bend sequence screen, the softkey ‘show library’
will remain available to get a graphical overview of the tool library as shown above.
After specifying machine part and tools the product and machine will be drawn on the screen.

In the graphical overview of the bendsequence, it is possible to change the order of bends simply by moving a bend to another place. Press the button ‘Move bend’ and the number of the
first bend is highlighted. Use the arrow keys to move this cursor to the bend that must be
moved. When the correct bend number is highlighted, press the enter key to select this bend.
Now use the arrow key to move the bend to the right place in the sequence. If the bend is on the
correct place, press 'enter' to confirm.
Swap Bends
With this command, two bends can change place in the bend sequence. Press the ‘swap bends’
button. Move the cursor to one of the required bends and press the ‘swap’ button or press enter.
Then move the cursor to the bend with which it must be swapped and press the enter key or the
‘swap’ button. Now the bends have been swapped. If for any reason the action must be cancelled, press the softkey ‘abort swap’ during the procedure.
•Restoring a bend sequence
A (partly) determined bend sequence is not automatically reset after leaving the bend sequence
menu.
After you re-enter the bend sequence menu it is possible to continue with the existing bend
sequence.
If you re-enter the bend sequence menu you have the following options:
2.q
‘new’start new bend sequence, the existing bend sequence is
reset
V0606, 2.16
Page 37
Delem
‘continue’continue with current bend sequence, the existing (par-
tial) bend sequence is restored and shown on the screen
If you have loaded a drawing from which a postprocessed bending program already exists,
there is a third option when you enter the bend sequence menu:
‘restore’restore bend sequence from postprocessed program, the
bend sequence is restored from this postprocessed bending program and shown on the screen
If you have drawn a new product in the menu "Product drawing" and you enter the bend
sequence menu for the first time, there is no existing bend sequence and postprocessed program yet, these previously mentioned selections are not shown.
•Minimum bending length
The minimum possible bending length will be calculated from the V-opening parameter (½ V),
but also depends on the angle to bend and the thickness of the material to be bend, see figure
2.z. If the programmed value for the wanted product does not correspond with the minimum
possible length, you will get a warning message on the screen.
2.r
•Machine/Tool selection
At each bend you can select one of the tools or machine shapes which are present in your
library. The displayed number is the number of the tool and machine part which is presently
selected.
Entering a new number will select another tool or machine part which will be drawn directly
on the screen.
With the "enter" key you can toggle between punch-, die-, machine upper- and lower part number.
It is also possible to turn the punch and die with respect to the machine shapes. To achieve this,
the tool number must be programmed negative.

•Store
After you have completed the bend sequence a CNC-program can be generated. This generated
program will be stored in the controller program memory.
2.7.Variants programming
The term ‘Variants programming’ means that the operator can make modifications to an existing program in the graphic menu, without having to build a new CNC program from scratch.
An existing program can be altered without loss of existing corrections and bendsequence. If
such an existing program contains proper axis values and product positions then this information can stay intact, only the latest changes (angle, sheet length) are recalculated and entered
into the program.
For instance, when a side length has been altered in the graphical bend overview and the
‘store’ command is given, then a question appears how to compute a CNC program.
V0606, 2.20
Page 41
Delem
2.u
When update (S4) is chosen, the existing CNC program is changed with regard to modified
values (angle, length), but other values of bend parameters stay the same. The expression ‘reuse corrections’ refers to the corrections that may have been entered in one of the production
modes. These production modes are explained in chapter 10.
When new (S5) is chosen, a new CNC program is calculated. Corrections in the existing CNC
program are lost.
In order to keep the existing program, check that the indication ‘Variants On’ remains in the
title bar. When you start an action or command that would seriously change the program, a
warning is issued by the control:
V0606, 2.21
Page 42
2.v
If you choose 'yes' (S4), the indication 'Variants On' will disappear from the title bar. This
means that the next time when a new 'postprocess' command is started, a new CNC program is
built and old corrections will be lost. When 'No' (S5) is chosen, the action is cancelled and
'Variants on' remains.
The message "CNC program and corrections will be lost" is not literally true. The CNC program is still present, but it cannot be updated anymore from the graphical menu. If the old
CNC program must be stored, it is still possible to go to ‘data edit’ mode and store the program
under a different product number.

0 = absolute: program the absolute Y-axis position for a bend.
1 = α: program the angle to bend. The required Y-axis position is computed.
Depending on this parameter, either the parameter 'angle' or the parameter 'bend position'
will appear.
Selection of one of the programmed materials, which are used to calculate the bending

has been processed from a 2D drawing, this value has been calculated.
This parameter is also required for 2D visualisation in a production mode (Automatic or
Step).
The parameter "connect" is to have a possibility to connect certain programs to one
another. This option can be used to produce 3-dimensional products. (See also the next
page).
•Connecting CNC programs
With the parameter Connect it is possible to create a 3-dimensional product. The control automatically executes the bend sequences in the different directions in succession. You program
the control as follows:
Instruction for 3-dimensional product programming (9 steps)
1Create the product in one direction.
2Create the product in the other direction.
There are now two bendprograms of one product in two directions. You connect these programs as follows:
3Select the program with the bendsequence in the direction which you want to execute in
the first place. You select the program of the product via menu 3, product selection.
4Go to menu 2, data editing. Select the parameter CONNECT. Enter the program number
of the product in the other direction.
5Select the second program as in step 3. Repeat step 4. If you want to connect two pro-
grams, as in this example, you enter the program number of the first program. The cycle
is closed.
When you want to execute more than two programs in succession (not necessarily to create a
3-dimensional product) the second program must refer to the third. The third program to the
fourth and so on. The final program of the cycle must always refer to the first program.
To produce products with connected programs the next four actions are necessary.
6Select the first program
7Select the Automatic mode
8Program the amount of products you want to produce with the ‘stock count’ parameter.
9Push the Start key.
When the first program has been finished the second program starts automatically. The program counter indicates the remaining amount of repeats.

flatteningThe sheet is folded in two. This is possible
after the sheet has been bent into a sharp
angle in a previous bend. The control calculates the precise Y-axis position for this
action: the surface of the die plus twice the
sheet thickness.
Y-axis positioning can be adjusted by programming a 'flattening offset'.
flattening and
bottoming
Note 1:
The flattening bends are shown here with a special flattening punch, but this is not required.
Note 2:
When bottoming operation is selected, the end of bend position of the Y-axis beam is depending on the working tonnage. If however the force is sufficient for the beam to go to the calculated Y-axis end of bend position, the beam stroke will be limited by the position value.
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.
The same as flattening, but now the control

position. The folded sheet is squeezed
between punch and die.
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 flattening.
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.
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 plate. By default,
the mute value from the programmed die is used.
Whether or not this parameter is present depends on machine settings.
Backgauge position. When a negative sign is programmed this backgauge dimension is
an incremental dimension. The incremental dimension is subtracted from the actual Xaxis position. Therefore this parameter can also be used as a chaining measure.
Only in case you have a configuration with a R-axis.
The function key (‘gauge func’) appears when you put the cursor bar on this X-axis parameter.
3.d
If you press ‘gauge func’ a window appears with three programmable parameters.
With this function you can program another ‘gauge position’ for this specific bend. The
V0606, 3.8
Page 51
Delem
gauge position (parameter GP) you can program depends on the backgauge dimensions.
Backgauge dimensions are programmed in the menu ‘program constants’.
Default gauge position = 0 (no lay on)
Other possibilities are:
gauge position = 1, lay on first level
gauge position = 2, lay on second level (only possible when number of gauge positions
(GN) = 3)
gauge position = 3. lay on third level (only possible when number of gauge positions
(GN) =4)
When you program another ‘Gauge position’ the backgauge position changes, but the
gauge position for the plate does not change. This means that the next two parameters
‘R-finger position’ and ‘X-finger position’ remain the same. See also example below.
Default value = the value in X-direction of the gauge position for the plate. This value
can manually be adjusted in this window, if required.
With ‘END’ you leave the window and the new values have been saved. If you press
‘cancel’ you leave the window without changes.
When you have changed the ‘Gauge position’ then the axes positions in X- and R-direction have also been changed. Therefore the parameters ‘backgauge position...X’ and ‘R-
axis....R’ have been changed. The new values depend on the dimensions of the back-
gauge finger which you have programmed in the menu ‘program constants’. When you
have changed the values of ‘R-finger position’ and ‘X-finger position’, then these
changes are also included.
Programmable parameter which determines when the parameter values for the next
bending will be active. The possibilities are:
0 = Bending number change (step change) at end of decompression (next bend parame-

ters active).
1 = Step change at muting position when the beam moves in opening direction.
2 = Step change at upper dead point.
3 = Step change at upper dead point without movement of any axis and the control goes
to "stop".
4 = Step change if C-input signal becomes active, without movement of the beam. When
you still have a beam movement there will be no retract function of the backgauge performed. See also code 5.
5 = Step change if C-input signal becomes active and the beam is in the upper dead point.
Now you may move the beam and the retract function of the backgauge will be performed.
10= Step change at end of decompression with the Y-axis beam waiting at the pinching
point until the backgauge is at the retract position.
11= Step change at mute position when the beam moves in the opening direction, with
the Y-axis beam waiting at the pinching point until the backgauge is at the retract position.
12= Step change at upper dead point, with the Y-axis beam waiting at the pinching point
until the backgauge is at the retract position.
13= Step change at upper dead point without movement of any axis. The Y-axis beam
will wait at the sheet clamp point until the backgauge is at the retract position. After the
bending with this code, the control goes to "stop".
15= Step change if C-input signal becomes active and the beam is in the upper dead
point. The beam may be moved but not necessarily. The Y-axis beam will wait at the
sheet clamp point until the backgauge is at the retract position.
Working speed (pressing speed). Initially, the value for this parameter is copied from the
parameter ‘pressing speed’ in the programming constants menu.
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 rank number of this angle, when counted from left to right through the product profile (figure 4.j). The digit before the dot describes this rank number, the digit after the dot
descibes the rank number of this bend in case of a bumping sequence.
In case of a normal angle, the bumping number should always be 1. In the case of a
radius bend, all bends in the bumping sequence should have the same angle number but a
different bumping number. Programming a radius bend in this manner will allow for
bumping correction in the production mode.
A backgauge number refers to a certain spot of the product, that can be placed against the
backgauge during bending. Such a spot is either a product end or an angle. The backgauge numbers in the product are counted from left to right, starting with 0 (see figure
4.k). For each bend you must program here which spot must be placed against the back-
stop. If the plate must rest on the backgauge finger, add 100 to the XN value. For each
next lay-on position, add another 100 to the backgauge value (200, 300, etc.).

In case automatic Z-axis are used the Z-axis value is computed from the: plate length, Zdistance (menu ‘Program constants’) and Z-position.
The flattening height need to be programmed when you make use of a special flattening
punch to flatten your product.
The programmable height is used to calculate the Y-axis value in case of "flattening". The
default-value for this parameter is the standard tool height, which is already programmed.
Every time that this standard height is changed, the flattening height will be made equal to this
tool height (due to safety reasons). See figure 6.g.
The total toolheight will be used to calculate the speed change point mute and the flattening
height will be used to calculate the end position of the Y-axis beam to flatten the product. The
calculation will take 2x sheet thickness into account. Also you can program a flattening offset
in the menu ‘Program constants’. This value will be added to the value of 2x sheet thickness.
Switch parameter, to account for differently mounted punches. Such punches could

•Edit die drawing
When starting the die drawing, the display prompts the main dimensions of the die:
The width V is the distance between the touching lines crossing.
After entering these parameters you are ready to draw the important outer dimensions of your
die. The right side of the die is the backgauge position. The mid-position of the V-opening will
be placed on the centre line of the press brake shape.
5.j
The length of the flat section on the right hand side of the V-grove will be used in order to calculate the minimum X-axis position for the R-axis collision detection with die (X-safe).
Function keys:
The softkey functions are exactly the same as for punch programming.
Calculated safety zone (minimum X-axis value), which will be used in the case a R-axis
is mounted. This to prevent finger to die collision. The indicated minimum value is computed automatically from the die dimensions as follows:
X-SAFE = FS + ½ V in which:
FS = flat section on the right hand side of the V-grove
V = opening value
In this formula also an extra small safety value has been added.
This second safety value will be active if the die is used in the turned position. This can
be achieved by programming the die in the bendsequence computation with a negative
number. For instance: Program for die number 2: "-2" if you want to use it in the turned
position. In this situation parameter ST will be used as safety zone for the backgauge.
The flattening height need to be programmed when you make use of a special flattening
die to flatten your product.
The programmable height is used to calculate the Y-axis value in case of "flattening".
The default-value for this parameter is the standard tool height, which is already programmed. Every time that this standard height is changed, the flattening height will be
made equal to this tool height (due to safety reasons). See figure 6.r.
5.m
The total height will be used to calculate the speed change point mute and the flattening
height will be used to calculate the end position of the Y-axis beam to flatten the product.
The calculation will take 2x sheet thickness into account. Also you can program a flattening offset in the menu ‘Program constants’. This value will be added to the value of
2x sheet thickness.
Second automatically calculated safety zone (minimum X-axis value) to be used in the
case a R-axis is mounted. The value is the distance from the middle of the V-opening to
the most outside point of the drawing of the die (on the right side). Also an extra safety
tolerance of 1mm is added. The situation for the die in turned position the distance to the

For backup operations, it is possible to make use of subdirectories. Subdirectories can be created in this menu. When the softkey 'backup directory' is pressed, a new window appears with
a list of available back-up directories. A selected directory can contain products and tools, so
each user can keep his own set of products and tools, if necessary.

You can make new subdirectories or delete existing ones with the softkeys 'make subdir' and
'remove subdir'. If there are subdirectories present, use the arrow keys to scroll to the required
directory and presss 'enter' to select it.
Function keys:

The 'load tools' procedure is different from the 'save tools' procedure. When you select 'load
tools' the control checks if the toolnumber already exists in the control. If not, then the tool is
automatically copied from disk to the control. If the toolnumber already exists then you have
three options:
-cancel (S3), the toolnumber is not loaded.
-overwrite (S4), the tool in the control is replaced by the tool from disk.
-rename (S5), the tool number of the tool on the disk is first renamed before it is loaded from
disk.
This means (in case of rename) that a new toolnumber is proposed. This new toolnumber is the
first free tool number in the tool library. Accept the proposed tool number with the enter key or
enter the number of another free tool number and press the enter key.
Delete a subdirectory. If the subdirectory is not empty the
controller returns the message 'unable to remove directory'.
5.t
Note:
Tools are linked to the control by their machine number. When a 'restore' operation is started,
the control will only show those tools, which have the same machine number as the control.
If for any reason the machine number is changed, a new tool back-up operation should be executed to save the control tools with their new machine number.

6.Products and tools back-up
6.1.Introduction
This chapter describes the procedures to make a back-up of your products and tools. The
procedures for saving or reading data are similar for all types of back-up media: floppy disk,
network or USB disk.
The actual back-up directory consists of a device (USB disk, network) and a directory. The
choice of devices depends on which devices are connected to the control. If necessary, directories can be created and selected. The back-up locations for storage of products and tools are set
independently.
6.a
V0606, 6.1

6.2.Directory navigation
When softkey ‘backup directory’ is pressed, a new window appears with a list of available
back-up directories.
6.b
In this window you can browse through the directory structure of your back-up device. Press
ENTER to look inside a subdirectory. To move one level up, go to the <PARENT> map and
press ENTER. To select the directory you are currently in, go to and press 'select'.
To change from one device to another, press ENTER on the <PARENT> symbol a number of
times until the highest level is reached. From there, select the proper device and choose the
correct subdirectory.
If a network connection is available you must first 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 with the softkeys ‘make subdir’ and
‘remove subdir’. If there are subdirectories present, use the arrow keys to scroll to the required
directory and presss ‘select’ to select it.
Function keys:
make
subdir
Add a new subdirectory. The name of the subdirectory can be any alpha numeric string of maximal 8 characters. Avoid the use of slashes (‘/’).

Delete a subdirectory. If the subdirectory is not
empty the controller returns the message
‘UNABLE TO REMOVE DIRECTORY’.
6.3.Product backup
To make a back-up of programs to disk, choose ‘Product backup’ in the main menu.
6.c
From this screen, a backup or a restore function is available. It is also indicated to which location a backup is made (floppy disk, network, etc.).

When ‘backup products’ has been selected, a screen like shown below should appear.
6.d
At the top of the screen, the back-up location is shown. If this location is not correct you can
change the subdirectory with the softkey ‘backup directory’ or you should go to the program
constants menu to change the device where products are saved to.
To save a product, enter its number from the list and press ‘enter’.

A back-up operation is carried out unconditionally. When a restore operation is started, the
control checks whether the product is already present on the control. If it is, you are asked
whether to replace the existing product or to cancel the restore operation.

To load or save only a few tools, go to the specific menus of those tools and save or load each
tool individually. This has been explained in detail in the chapter about tools.
A restore operation runs similar to a back-up operation, when it is started a warning is given
that the existing tools on the control will be replaced by the tools that are imported.
Tools are linked to the control by their machine number. When a restore operation is started,
the control will only import those tools, which have the same machine number as the control.
If for any reason the machine number is changed, a new tool back-up operation should be executed to save the control tools with their new machine number. If this has not been done, the
control will detect no tools at the next restore action.

7.Program Constants
7.1.Introduction
Choose ‘Program constants’ in the main menu to program the programming constants. The
program constants are divided across several pages. They are discussed in the following sections.
7.2.General
7.a
Use the keys 'next page' (S2) and 'previous page' (S1) to browse through the various pages with
parameters. Use the arrow keys up/down to select individual parameters.
Select the language for the on-line Help function. By default, the Help language is set to
the same language as the user interface. If that language is not available as on-line Help,
English is chosen.
The Help function is available in the following languages:
0 = English
1 = German
3 = French
4 = Italian
5 = Dutch
8 = Spanish
When the cursor is on the parameter 'Help language', the function key 'add help language'
appears. With this function key you can install a new help language on the control. Make sure
the required help file is present on the control disk or another accessible location (network,
USB disc).

The materials are initially listed according to their material number, which is shown in the first
column (ID).
The list can be sorted according to the different properties. If you have a mouse available, click
on the title of a column. The materials will be sorted in ascending or descending order of that
property.
To change an existing material, go to the relevant line and change the values as you see fit. Use
the ENTER key to confirm a typed value.
To delete an existing material, move the cursor to the relevant line and press the function key
‘delete material’ (S6) to erase the values.
To program a new material, move the cursor to an empty space and start programming its values.

When there are several bending machines in a factory, it can be useful to give the control
on each machine a unique machine number.
The selected machine number will be stored with the bending program. This number will
be checked when a program is read from floppy or a network. When the machine number
does not match you must confirm to read it anyway or not. If you do not confirm the
V0606, 7.5
Page 96
question the action will be aborted.
The machine number is also stored in the filenames of tools. When the machine number
is changed in this screen, you are prompted to make a new backup of your tools because
the filenames of all tools have been changed according to the new machine number.
Parameter to switch computation of angle corrections on or off.
When this parameter is set to enabled, the operator can enter the measured angle of a
bend and have angle corrections calculated.
With this parameter is set whether or not the field 'measured angle' is available in the corrections window. See chapter 10 for more information about the corrections window.
Toggle function, to switch the database with angle corrections on or off.
Angle corrections are entered in production mode (automatic/step by step). These corrections are stored in the product program. Beside this, it is also possible to store these corrections in a general database with angle corrections. This way corrections that have
once been entered for certain bends remain available for future use in other products.
When this setting is switched on, 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 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 first five 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 resulting correction
has a difference of more than 5° with one of the two other bends, there will be no correction offered.
In the ‘data edit’ mode you can change the value of the programmed parameters. This
can also influence the value of other parameters. With this parameter you can choose to
have the other values automatically recomputed. Program ‘auto computations edit’ to 1.
There are three cases in which automatic computation can be used.
1. In case you change the value of the parameters ‘material type’ or ‘material thickness’
V0606, 7.6
Page 97
Delem
then the following parameters are automatically recomputed and changed by the control:
- Pressure
- Decompression distance
- Crowning device setting
2. In case you change the value of the parameter ‘length’ then the following parameters
are automatically recomputed and changed by the control:
- Pressure
- Decompression distance
- Crowning device setting
- Z-axis position
3. In case you change the parameter ‘punch’ or ‘die’ and the height of the new punch or
new die is different AND ONLY in case the ‘bend method’ is ‘bottoming’ or ‘flattening’
then the following parameter is automatically recomputed and changed by the control:
- Y-axis position (‘bend position’)
(When the ‘bend method’ is ‘air bend’ (normal situation) the Y-axis position is calculated in the automatic mode!)
If the automatic recomputation is switched off (default situation) then these parameters
stay the same. However, when you go to these parameters with the cursor keys the
recomputed value is displayed in the input row. When you press ‘enter’ the recomputed
value replaces the old value after all. So, you can choose to change the values.
0 = angular format
1 = projection method
When you have two independent X-axes (X1 and X2) and the option OP-X1X2 has been
installed, you can program the values for X1, X2 in a certain relation. This means that
you program X1 and an angle value (angular method) or in a projection measure.
Please ask the option description from your supplier when this option has been installed.
Only available when this option is installed.
Default Y-axis opening value.
The value programmed here is used as initial value for the parameter ‘Y-axis opening’ in
the Data Preparation menu of the programming mode.
Default value for the parameter ‘code’ in a bend program. This parameter determines the
moment of step change in a bend program. Initially the code parameter is set to the value
programmed here during postprocessing and during programming.
The default value of this parameter = 2.
See chapter ‘data preparation/data edit’ for more information about the code parameter.
During the postprocessing, the waiting time of the X-axis at step change is put to zero.
With this parameter you can preset a longer waiting time when needed for product han-
0 = Internal / 1 = bendallw.tab
Bend-allowance: correction of the X-axis due to plate shortening after bending. With this
parameter the method for bend-allowance calculation is chosen. ‘Internal’ means the
standard formula of the control is used to calculate the bend-allowance. ‘Bendallw.tab’
means a bend-allowance table with correction values can be used. The choice ‘Bendallw.tab’ is only available if a bend-allowance table is present on the control.
If a table has been chosen, the name of that table (if it has a name) is shown on the
screen.
0 = correction off / 1 = correction on
With this parameter you can choose whether or not you wish to have programmed values
corrected for bend-allowance. This on/off setting only refers to corrections during product programming in the menu ‘data preparation’. 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 in production mode (see ‘Automatic mode’).
Press the key to select the required setting.
This choice has no effect on the postprocess function in the drawing mode. When the control
V0606, 7.8
Page 99
Delem
uses the postprocess command to calculate a CNC program from a drawing with bendsequence, the control will allways take bend-allowance into account.
When a bend-allowance table is present and the cursor is on the parameter ‘active bend allowance table’ then an extra function key is available: ‘edit table’. With this softkey the table can
be modified to meet user requirements. The table appears in a new window, with its own set of
function keys.
7.g
Each line contains a table entry, with several parameters. In this screen, the following function
keys are available:
Funtion keys:
new entryEnter a new line in the table.

entry
Use the arrow keys to scroll to the field you wish to change. Then type the new value and press
ENTER. It is not possible to create a table through this menu. Only when a table has been
loaded into the control is it possible to edit its contents.
For more information about bend-allowance tables, we refer to the Delem manual of the bendallowance table.
The calculated depth position for the Y-axis beam in case of flattening your product
depends on the programmed flatten height of your special tool and the sheet thickness
(x2) and the here programmed offset to realise a flattened product as you require.
