P30SECURITY DISTANCE (DISTANCE AT LOW SPEED)
This is the safety distance from the stroke end (SE) at which the back gauge
switches from manual high speed (P14) to manual low speed (P13), or vice
versa.
This security distance provides extra security when approaching stroke end
and avoids vibrations at the end of the ball screw drives.

MACHINE PARAMETERS PAGE 9
P31NUMBER OF SUPPLEMENTARY LEGS
In the case of an axis with several gauge arms, P31 defines the number of
supplementary arms (max. 7).
PAGE 10 MACHINE PARAMETERS DNC 60 G
P32LEG DISTANCE
P32 defines the separation between two consecutive arms. The separation
between 2 consecutive arms being always the same.
P33SHEET PRESENT SPEED
In the case of a take sheet cycle, without square, the P33 defines the speed at
which the axis moves once the clamp has detected the sheet.
P34TYPE MANAGEMENT AXIS
Remark: This field is accessible only on X4, X5, X6.
Definitions:
y The dependant axes will follow the cycle sequences.
y The independent axes will execute their own advance sequence with
their signal "Start Xn".
y The axes with automatic "Start" will have their positioning departure
synchronized with the departure of the shear axes (X1/X2/X3).
y The axes with an external "Start" will have their positioning departure
commanded by their signal "Start Xn".
Modes:
0 or __: Auxiliary axis dependant on the cycle with automatic "Start".
1 (D0): Auxiliary axis independent of the cycle with external "Start"
(masked time).
4 (D2): Auxiliary axis dependant on the cycle with external "Start". In this
mode, the axis' sequences follow the cycle sequences but the cycle
does not wait for the end of axis positioning to execute the advanced
sequence (masked time).
2 (D1): Only for X4, this mode indicates that X4 is used as a second
backgauge.
MACHINE PARAMETERS PAGE 11
X1, X2: frontgauges
X3, X4: backgauges
Remark: P35, P36, P37 are accessible only on X1 and X3.
P35RETRACTION DISTANCE
Sufficient distance for the axis retraction.
This retraction is made:
1) Before the cut for backgauges.
By cutting, the sheet spreads. The gauge must be retracted.
2) After the cut for frontgauges.
After the cut, the sheet holder moves upward. The sheet has to be
retracted in order to enable the raising of the blade without rubbing.
The cycle will only wait for the axis to reach its retraction value (in high
speed), then the axis will be stopped independently of the machine cycle.
P36HOLD-DOWNS TIME
Negative value: This value is interpreted as a retraction delay time and
allows to wait for the hold-down to pressure up before
starting the retraction.
After receiving the HOLD-DOWN CLOSED signal
(0V) the DNC waits for the time programmed in this
parameter before starting the retraction.
Positive value:
The programmable range for this time is situated between -9,99 and +9,99
seconds.
This parameter (programmed positive) defines machine
functioning without the HOLD-DOWN input signal.
Effectively this signal is replaced by the programmed
time. As soon as the CUTTING AUTHORIZATION
signal is furnished, the DNC will wait for the
programmed time then start the retraction.
After this time has elapsed, the DNC considers that the
sheet is held down.
PAGE 12 MACHINE PARAMETERS DNC 60 G
P37CORRECTION FACTOR BLADE GAP
This parameter allows to correct the axis positioning value as a function of
the blade gap defined in the product.
The DNC applies a constant correction, to all the programmed positioning
values, as a function of the blade gap and this parameter.
Cv = Cp + P37 * Jc
Cv Axis positioning value (target value)
CP Programmed value
Jc Blade gap
P37 positive Back gauge cycle

P39TDCTIME
This parameter is only used if for the RAKE ANGLE (AF2) and CUTTING
LENGTH (AF3) functions only one potentiometer is used.
This time is used to delay the adjustment of the RAKE ANGLE function
(AF2 P70 = 2 or 50) after reception of the TDC signal in order to wait for
the stabilization of the blade at the TDC.
Effectively, in this configuration it is only possible to adjust the rake angle if
the blade is completely stopped at the TDC.
This double parameter defines the maximum separation authorized between
X1 and X2 with the clamps opened and closed.
This safety control is switched on as soon as an axis moves. If the limit is
reached, the axis is stopped and an error is signalled.
It also allows to deal with all mechanical backgauge configurations (eg.
gauges joined by a bar).
P41DISTANCE "SHEET PRESENT"<–>"BOTTOM OF
MECHANICAL CLAMP"
This distance should be greater than the distance between the sheet detector
and the mechanical bottom of the clamp.
It is used in sheet taking cycles without square.
P42DISTANCE "SHEET PRESENT"<–>"BOTTOM OF
ELECTRONIC CLAMP
This distance should be less than the distance between the sheet detector and
the mechanical bottom of the clamp. It is used in sheet taking cycles with
square or in "Square=2" mode.
It prevents the clamps from touching the sheet before they are closed.
"
PAGE 14 MACHINE PARAMETERS DNC 60 G
P43CLAMP DISENGAGEMENT TIME
Remark: The programming of this parameter determines the use or not of
clamps.
Undefined = machine without clamps
Defined = machine with clamps.
This delay is used to make a safety control on the disengagement of the sheet
from the clamps.
In the case of a cycle "without sheet", "without cutting", the clamps will open
then the axis will move backwards to disengage the clamps.
The DNC will control only after the P43 time that the "sheet present" signal
has disappeared. If the sheet remains blocked in the clamps, the axes are
stopped and an error is signalled.
P44DISTANCE SHEET INDEX <–> BLADE
This parameter indicates the distance between the sheet detection point and
the cutting line.
This parameter is used in the case where an indirect measure of the sheet is to
be made before it is cut.
This working mode is selected by programming the value 2 (D1) in the Take
sheet field.
P49EJECTION TIME
This parameter should only be programmed in the case where the clamps are
equipped with ejectors.
In the case where the Ejection field has been defined (on the sequence
page) the ejection cycle is as follows:
P49 positive:
1) Set ejection signal
2) Ejection time (P49)
3) Clamp opening
4) Reset ejection signal
P49 negative:
1) Clamp opening
2) Set ejection signal
3) Ejection time (P49)
4) Reset ejection signal
MACHINE PARAMETERS PAGE 15
P50MAXIMUM SHEET WIDTH
This parameter should only be programmed in the event that the machine is
equipped with function (F3), measuring the length of the cut or function
(F2), measuring the rake angle. It defines the maximum cutting length of the
machine.
The three parameters which follow (P51, P52, P53) should be programmed
only for machines equipped with 2 frontgauge clamps (X1, X2) of which X1
(left leg) is fixed and X2 (right leg) is fitted with an articulated arm.
P51DISTANCE STOP X1<–>SQUARE
This parameter defines the distance between the left leg and the right end of
the blade (generally the square).
P52ARTICULATED ARM LENGTH
This parameter defines the distance between the axis of the articulated arm
and the axis of the cylinder holding the sheet.
P53MAXIMUM ROTATION ARM ANGLE
This parameter defines the maximum angle of rotation authorized for the
articulated arm.

P58DISTANCE POTENTIOMETER
Horizontal distance between the left edge of the lower blade and the
potentiometer position. This parameter must be greater than P55 and less
than or equal to P50 (P55 < P58 ≤ P50). If this parameter is not definied, it
will take the default value of P50.
MATERIAL
The name of the material is programmed in 4 characters in the fields located
on the line headed -MATERIAL-.
The name of the material is defined in alpha numerical using the manual
displacement keys. You will find a description of the use of the manual
displacement keys for defining the alpha numerical characters in the
paragraph concerning the auxiliary functions.
DEFAULT THICKNESS
For each material you can program a default thickness. When clearing the
buffer or selecting another material, if the default thickness is defined, then it
will be transferred in the Thickness field of the product.

READER.
CTS and DSR signal management for flow
control.
When the DNC is receiving, and if the DNC
wishes to halt transmission temporarily to
process the received data, the CTS line goes
low, indicating that only one more character
can be accommodated (if more arrive, they will
be lost).
With this protocol in force, the READER must
thus send only one more character when the
CTS line goes low.
On the other hand, when the DNC is sending,
and the READER forces the CTS line low, the
DNC stops sending characters immediately
(not even 1 more is sent).
3 Same as for protocol 2, but when the DNC
forces the CTS line low, it does not expect to
receive any more characters (not even 1).
Therefore, the READER must not send even 1
more character, the moment the CTS line goes
low.

P67NONE AT PRODUCT SEARCH IN CASSETTE
If P67 = 1 The DNC inhibits the various calculations
relative to functions F1, F2, F3 (blade gap, rake
angle, cutting length) whenever a product is
recalled from the product memory. Otherwise,
all the relevant calculations are performed at
each product recall.
If P67 = 2 The DNC inhibits the calculation of the TDC. The

AF dependent on the machine cycle with
automatic START.
The code 0 prohibits display of the function,
but allows to reserve the function outputs in
digital mode. The aim of this is to avoid a
difference of the auxiliary functions as a
function of the configuration of the machine
options. The wiring can be standardized.
Cycle-independent AF with independent
advance sequence and external START.
Special AF with internal calculations:
- for F1 and F5: blade gap
- for F2: cutting angle
- for F3: cutting length (BDC)
- for F4: timer for flying cut
- for F7: sheet thickness measurement
AF dependent on the cycle for the advance
sequence, but having its own management
start, supplied by its corresponding START
AFn signal.
P71DIGITAL MODE
This parameter configures the AF in digital mode.
The programmed number (maximum 8) corresponds to the number of 24V
output wires (binary coded) for the chosen function. This number of outputs
is reserved.
Calibrating digital functions
The parameters P79 and P80 can be used to define a limit for the binary
codes attributed to the function.
Example: A digital function programmed with 3 wires accepts the digital
values from 0 to 7. These values are used by default if P79 and
P80 are not programmed. If you program P79 = 2 and P80 = 5,
the codes 0, 1, 6 and 7 are excluded.

P106b<P106
P107 Return Sheet Support at TDC
This parameter controls whether the sheet support goes back to position 1
(high) after the blade reaches TDC or whether it remains in the lower
position.
If the value for this parameter is 1, the sheet support goes to position 1 at the
end of the time specified in P102.
You may also use parameter P107 if you need to ensure that the sheet
support only goes up after blade, eg, to avoid collisions between the two.
P115 Sheet Support Start Delay
This parameter is the delay between the cutting authorization signal and the
start of the sheet support cycle.
(Value range : from 0.01 to 9.99 seconds, Default value = 1 second)
Reminder: in a work cycle without sheet support, parameter P36 is the
specified time between the cutting authorization and the moment where the
hold-downs are tightened, that is, when the blade can start going down.
When using a sheet support, you must enter a value for P36: this parameter
then acts as an additional security.
As a rule, the sheet support cycle must start after the metal is clamped: P115
must be greater than P36.
However, in special situations, the support cycle may need to start before the
metal is clamped. In this case, P115 must be less than P36.
Using a pressure sensor may shorten the duration of both P115 and P36.
ANTI-TWIST PARAMETERS

Sheet Support on page 63 of this manual.
P116 A-TW Start Delay
This parameter is the delay between the cutting authorization signal and the
start of the anti-twist device's cycle.
(Value range : from 0.01 to 9.99 seconds, Default value = 1 second)
Reminder: in a work cycle without sheet support, parameter P36 (Hold
Downs Time) is the specified time between the cutting authorization and the
moment where the hold-downs are tightened, that is, when the blade can start
going down.
PAGE 36 MACHINE PARAMETERS DNC 60 G
When using a sheet support, you must enter a value for P36: this parameter
then acts as an additional security.
As a rule, the anti-twist device cycle must start after the metal is clamped:
P116 must be greater than P36.
However, in special situations, the anti-twist device cycle may need to start
before the metal is clamped. In this case, P116 must be less than P36.
Using a pressure sensor on the hold-downs may shorten the duration of both
P116 and P36.
P108 A-TW Time Up
Estimation of the time needed for the anti-twist device to go up to the high
position.
This parameter is similar to P105 for sheet support.
P109 A-TW Time
This specified time starts when the blade is at BDC and the anti-twist device
at a low position, and ends when the A-TW device starts going up.
(Value range: from 0 to 9.99 seconds)
P110 A-TW Time Down
This parameter is an estimation of the time needed for the sheet support to go
down to the lower position.
(value range : from 0 to 9.99 seconds)
P111 Return A-TW at TDC
If the value for this parameter is 1, the anti-twist device goes back up after
the blade reaches TDC and the time specified in P109 has elapsed.
Use this parameter if you need the anti-twist device to go back up after the
blade.
If this parameter is at 1, the auxiliary functions (1st blade gap, 2nd blade gap,
cutting angle) are adjusted one after the other.

The procedures described above allow to set up only the analogue functions.
It will subsequently be necessary to adjust the position parameters (P74, P75, P76, P77, P78) for functions F1 and F2.

1) Usually the value P79 = 0 is programmed.
You can also program, if necessary, on this parameter a time offset in

2) Program in P80 the time in 1/10 of seconds necessary to cut across
the whole length of the machine (with max angle).
SPECIAL SHEAR FUNCTIONS PAGE 49
FLYING CUT FUNCTION (F4)
The Flying Cut input (at 24V) allows to automatically link several cuts
without having to release and press again the foot pedal in order to obtain the
subsequent cut. The Cutting Authorization is issued as soon as the TDC is
reached and the axes are in position.
In order to allow sufficient time to the operator for putting the sheet against
the backgauge, it is possible to introduce a time-out between the end of the
axes positioning (and the return to TDC) and the output of the Cutting Authorization signal.
This time-out can be programmed, per sequence, in AF4 which will have
been defined in the Flying Cut mode beforehand.

SHEET SUPPORT
Sheet supports are used to support metal sheets before hold-downs are
clamped (before shearing). They also help the sheared parts to slide down
onto a tray or stacker once they are cut.
The cycle of a sheet support starts after the hold-downs are tightened and
ends after they have been released (after the blade has reached the bottom
dead center).

FUNCTIONALITIES PAGE 55
CONFIGURATION
When using a sheet support, you need to define a number of inputs, outputs
and parameters.
Inputs
C1SupTol: Input used for the sensor on position 1 (high
position), regardless of the number of positions
of your support.
C2SupTol: Input used for sensor on position 2:
= low position on a 2-position support
= high position on a 3-position support
C3SupTol: Input for sensor on position 3, which is the low
position for 3 position support
Connecting 3 sensors to the numerical control is enough to indicate to the
DNC that you are using a 3-position support.
CprSeTol: CprSeTol is the short for Capteur Pression Serre
Tôle: Hold-down Pressure Sensor.
This input is optional. When active, it signals
that the metal holddowns are tightened and that
the sheet support cycle may start.
Reminder: The hold-downs are typically
controlled by parameter P36 Hold Downs
Time: the countdown for the specified time
starts as soon as the Cutting Authorization is
given.
This parameter must be configured, even when
input CprSeTol is used. In this case, the
specified time is used as a security.
However, parameter Hold Downs Time may
be used on its own, that is, even when input
CprSeTol is not connected.
Outputs
SupTolUp: Output that controls all upward moves of the
sheet support.
SupTolDn: Output that controls all downward moves of the
PAGE 56 MACHINE PARAMETERS DNC 60 G
sheet support.
STSingle: This output switches to 1 when the output
SupTolDn becomes active, and switches to 0
when SupTolUp becomes active.
This ouput acts as a unique control that sends the
sheet support on low position and holds it down
for the required duration (in supports where the
high position is the default, eg in a monostable
actuator).

SCREEN DISPLAY (FOR THE OPERATOR)
This icon displays on the operator screen whenever the
SupTol field is available, that is, whenever a sheet support is

When the value in this field is 1, the sheet support is activated
for the current sequence.
The value in this field only applies to the current sequence: it
may change at every sequence.
FUNCTIONALITIES PAGE 57
CYCLE OF A 2-POSITION SHEET SUPPORT
A 2-position sheet support may be configured in several ways:
- with 2 sensors (C1SupTol and C2SupTol) controlling the actual
position of the support,
- with 2 specified time parameters P105 and P106: the actual position of
the support is not controlled,
- with 1 or 2 sensors (C1SupTol / C2SupTol) and 1 or 2 specified time
parameters (P105 / P106).
This section explains how the most common configurations work.
Other configurations may work just as well. However, they are not
documented here.
Configuration 1: 2 sensors (C1SupTol and C2SupTol)
In this configuration, the position of the sheet support is controlled by 2
sensors C1SupTol and C2SupTol. Parameters P 103 and P106 are not set.
(SupTol) = 1
At the beginning of the work cycle, the sheet support is always in high
position.
As soon as the DNC receives the signal for cutting authorization (or cut
order), the countdown of parameter P115 (SHEET SUPPORT START DELAY) starts. At the end of the countdown, the sheet support goes down to
position 2 (low), and activates the sensor located at that position.
Once the blade reaches BDC and the support is in position 2, the countdown
of the specified time SHEET SUPPORT TIME (P102) begins.
If the value in the SupTol field of the next sequence is 1, the support will go
back to position 1 (high) at the end of the countdown. If the value is 0 or
undefined, the support remains in position 2 (low).

At the beginning of the working cycle, the support goes down to position 2
(low).
The support then remains in the low position until the blade reaches BDC.
At that point, the DNC checks whether the support is used in the next
sequence (SupTol = 1). If it is, the support goes back to position 1 (high)
after SHEET SUPPORT TIME. If not, it stays in position 2 (low).
Configuration 2: 2 Parameters P105 and P106
In this configuration, the sheet support is controlled by parameters P105 and
P106. (The DNC does not know the exact location of the support, but
extrapolates it based on the statuses of these 2 parameters).
The operating mode of the support as controlled by the time parameters P105
and P106 is very similar to that controlled by 2 sensors, with the following
exceptions:
•The sheet support stops going up when the time specified in P105
(TEMPO SUPPORT TOLE UP) has expired. (Unlike
Configuration 1, there is no sensor signal C1SupTol).
•The support stops going down when the time specified in P105
(TEMPO SUPPORT TOLE UP) has expired. (Unlike
Configuration 1, there is no sensor signal C2SupTol).

(SHEET SUPPORT TIME DOWN) has expired.
The DNC has no control of the exact location of the support when it is
lowered. The support stops going up when sensor C1SupTol becomes
In this configuration, parameter P106b is set. It is used as an additional
security (“watchdog”) when the support starts going down.
The sheet support must leave (and de-activate) sensor C1SupTol before the
time specified in P106b (SECURITY DELAY DOWN) has expired.
If it doesn’t, the work cycle is interrupted and a pop-up appears on the
screen.
Parameter P105 (SHEET SUPPORT TIME UP) acts as a security when the
support rises.

support goes down to position 2 (intermediate), and activates the sensor
located at that position.
Once the blade reaches BDC, the support goes down to position 3 (low),
while the blade goes back up.
FUNCTIONALITIES PAGE 61
When the support reaches position 3 and activates sensor C3Suptol, the
countdown of the specified time SHEET SUPPORT TIME (P102) begins.

ANTI-TWIST DEVICE
An anti-twist device is a piece of equipment that will prevent the sheet from
twisting when you cut lengthy pieces of metal.
When you start cutting, the device is in high position and holds up the metal
sheet. It is then lowered to support the sheet during cutting.
The DNC 60 G16 controls this type of device in the same way as a 2-position
sheet support (without sensors), that is, with specified times (for more
details, please refer to section Sheet Support on page 55).
INPUTS/OUTPUTS
In order to implement an anti-twist device, you must configure the 2
following outputs:

In order to facilitate the starting and the follow-up of the Inputs/Outputs
state, it is possible to visualize the Inputs/Outputs pages during the machine
cycle.

key is to be pressed 4 times.
INPUT CLEARANCE X
The clearance of the backgauge X towards the back of the machine allows to
avoid the spin of the sheet when a cut is only of low width.
This functionality is active as soon as the input Clearance X is
configurated.
In SEMI-AUTOMATIC or AUTOMATIC mode, as soon as the blade goes
down, or in MANUAL mode:
- An ascending front on this input provokes the sending of X to
LSW+.
- A descending front on this input provokes the standstill of X.
BACKGAUGE FOLDAWAY X
The backgauge foldaway allows to cut sheets longer than its max. limit
switch.
In the MACHINE PARAMETERS page, the 2 following parameters must
be configurated:
y P94 = PARK DISTANCE (see figure).
y P95 = CRAWL DISTANCE (see figure).
P94 defines the safety distance from the max. limit switch where the gauge
is retracted.
The PARK TARGET (= LSW max. – P94) is the absolute value from which
the gauge is completely retracted.
INPUT/OUTPUT CONFIGURATION PAGE 65
P95 defines the transition distance between the normal position of the
backgauge and its retracted position.

Input / Output
•IN BG Dn: Input for the foldaway down sensor. This sensor must be in
the park zone where it will stop the movement of the backgauge before
the rise. The stop when the backgauge goes down is done by this
sensor. (This input must be configurated.)
•IN BG Up: Input for the foldaway up sensor. This sensor indicates the
up position when the backgauge is retracted. (This input can be
configurated.)
•OUTBg Dn: Output to active the backgauge going down. (This output
must be configurated.)
•OUTBg Up: Output to active the backgauge rise. (This output must be
configurated.)
Remark: If the IN BG Dn input isn’t activated and the IN BG Up input
isn’t configurated, the backgauge isn’t necessarily at the up
position for the software.
Functionnement
If X MEM is not defined and the foldaway takes place (entry of X in PARK
zone), after the stopping of the axes and the auxiliary functions the DNC will
supply a pressure during the time defined by P96d, allowing to move up the
backgauge. The pressure stops with the help of the activation of the IN Bg
Up input (if it is configured) or by the end of the temporization defined by
P96a. If the temporization has finished before the input is active (and
configured), a message is displayed with a pop-up.

PAGE 70 MACHINE PARAMETERS DNC 60 G
INTERNAL BACKUP (SAVE)
A machine parameter and tools backup is available in the internal memory. A
restoration can also be performed from this same internal memory.
This functionality is exclusively used by the manufacturer to memorize the
parameters and tools state, at the time of the delivery of the machine.
In the event of problems, this will allow the operator to easily reload the
original parameters and/or delivered tools. This can be done without
connecting the DNC to a PC.
Note: Only the last compatible backup can be restored.
The memory quantity is limited. Each save takes up memory space (no
rewrite possible) and the number of backups depends on the software version
and the number of tools.
If this memory is full, it can only be deleted by reinstalling the boot software
(See further). This is an operation which must only be done by a qualified
and trained person.The number of backup saves available (generally 1 to 2)
is enough for the correct use of this function:
Backup are usually performed:
• When the machine leaves the factory.

INTERNAL RESTORATION OF PMS AND TOOLS
This functionality allows the owner of the machine to restore the original
factory parameters. This can be used in the event of problems by the
operatorm, assisted by the manufacturer/dealer.
The parameters restoration will replace the current contents of the DNC by
the last parameters save (generally performed by the manufacturer upon
machine delivery).
The tools restoration will replace all tools data which have the same number.
The tools which have a different number to those in the backup are not
affected by the restoration.
Example: The punches number s 1 and 2 have been saved.
The user has modified the data of the punches 1 and 2, and has
added the punches 12, 14 and 15.
At the moment of the restoration, the value of the data of the
punches 1 and 2 will be replaced by those of the saved tools.
The punches 12, 14 and 15 aren’t affected.
Only the last compatible backup can be restored.
To restore the machine parameters and tools, go to the TRANSFER RS232
page from the main menu.

INPUT/OUTPUT CONFIGURATION
The configuration of the inputs/outputs of a DNC consists in assigning a
software function (see paragraph Definition of inputs/outputs) t
input or output of the numerical control.
The inputs and outputs, when they are not being used, have the following
designations in the input/output list:
Digital Analogical Voltage
F dig 1 Pot F1 A analog 1
F dig 2 Pot F2 A analog 2
. . A analog 3
. .
. .
F dig 20 Pot F8
CONFIGURABLE AXES AND FUNCTIONS
o a given
Availability of an axis or a function is in direct relationship with the
hardware. The DNC 60 G16 can handle a maximum of 4 axes. It is therefore
not possible to configure all the axes which are available in the software, but
only 4 among them. The same is true for the auxiliary functions within the
limits of the available inputs/outputs.
AXES
The configuration (which will cause the axis to appear on the CRT) can be
achieved by programming the limit switches (+,-) of the relevant axis.
