DOCUMENT VERSION

This manual has been updated for software version P: ModEva series SSBFxPx DNC880S SWBMHPx
Note The software version P introduces a number of additions and
improvements for the beam requiring a reconfiguration of the beam parameter pages. This version also introduces a final approach speed instead of a final approach voltage for the BDC-positioning. Both final approach parameters are described in this manual. More generally, both the previous and the new operation of a parameter are described whenever the basic functioning has been changed in a more recent software version.
This V5.0 version contains following additional information.
P45, P45b, P46 additional info + diagrams.
Down diagram corrected and updated (V5.0).
Tips: how to smooth movement high speed down and arrival
at TDC.
Description input "pause return beam".
Sensitive mode, possibility to continuesely move the beam
up/down (se e Operating modes)

INTRODUCTION / CONVENTIONS

INTRODUCTION / CONVENTIONS

This manual describes the machine parameters of the ModEva numerical controls for synchronized press brakes and other, similar controls like the DNC880, the DNC1200 and the DNC60 and DNC600.
The parameter descriptions correspond to the standard version of the ModEva software. Note that certain parameters described in this manual are shown only for specific axes-configurations or selected options.
N2X- and CAN-axes para meters for X, R and all other digital axes are not described in this manual. Refer to the specific documentation for detailed information.
Numerous special options and configurations exist for the Cybelec numerical controls. Examples include Bending aids, Tool changer, Angle measurement, Safety PLC data link, Tandem configuration, etc. This manual contains no or limited information about the particular parameters for these options and configurations. Refer to the specific documentation for detailed information.
Most chapters in this manual are dedicated to specific machine parameter pages, e.g. Auxiliary Functions, Beam, Configuration, etc.
The titles of these chapters correspond to the titles of the ModEva parameter pages. Each chapter details the parameters contained in the corresponding parameter page(s).
A few chapters contain more general information, e.g.
Abbreviations, Beam parameters, Beam modes and Beam cycles. It is recommended to study this information prior to
consulting specific parameters. A typical value is given for many parameters. This typical value can
be used in most cases, or at least serve as a good starting point. Note, however, that optimum parameter values strongly depend on machine construction, - size, hydraulic configuration, etc.
References to other parameters, DNC pages etc. are shown in bold and use a different font, e.g. P01, Control loop, DNC page Bend Numerical. In most cases, reference to “machine parameter xxx” is written as “Pxxx” since this is shorter and easier to read. The parameter name is given as well since this avoids having to search for additional information in most ca ses.

OPTIONS

DNC-Options are optional selec ta ble extensions to the standard D NC­software. Some options are available as standard, others are available at extra cost, and a few are exclusive to a specific machine manufacturer or application.
The selection field in front of the option number selects whether the option is activated or not: Select – to d eactivate and + to activate the option.
The choice whether to activate an option or not is determined by the hardware of the machine. Therefore, no typical values are given in the description of the options.

PRODUCT PARAMETRIC

Function Selects to display the page Product
Parametric products offer a fast and easy way to modify pre­programmed 2D profiles. First, 2D product data is entered for a typical, representative part in the normal way on the Product Numerical page. Next the bend sequence is determined and the part is produced and optimized as usual. The final DNC program for the part is the basis for the parametric product.
On the Product Numeri cal Par amet e rs page, the parameters A to H can be assigned to various data elements of the basic product. These parameters are given a meani ngful description (field Caption), and limit values (fields Min and Max) as well as a default value (field
Suggested) are defined. Finally, the field Parameters is set to Active to activate parametric programming for this product.
Note Changing the field Parameters requires key level 3.
The picture below illustrates the defined parameters for a simple U­profile:

A slave axis is linked to a master axis. A common application is a backgauge X-axis with two servodr i ves. The first servodrive is driven by a regular X axis. The second servodrive is driven by a free axis configured in slave mode of the X master axis.
Note A bending aid axis cannot have a slave axis.
Note For the ModEva, the master axis and the corresponding slave
axis must be located on the same NMX/NMS group. This restriction does not apply to the DNC880s

BEAM PARAMETERS

INTRODUCTION

Many parameters are provided to permit optimal adjustment for all machine configurations and the various hydraulic systems in use.
Virtually all beam parameters have a single, specific function. A few exceptions to this rule exist. In these cases, the parameter description details the particular functions.
Changing the setting of a parameter with a single, specific function does not directly affect another parameter or function. For example, changing the high speed voltage down does not directly affect the low speed down or the return movement of the beam. Note, however, that this does not mean that c hanging a given parameter will not require to adapt another parameter: For example, changing the high speed voltage down normally also requires to adapt the deceleration ramp and/or –distance parameters.
As a rule, changing a parameter will also require to adapt one or more other parameters, which in turn could even require further par ameter changes. Consult the special chapters Beam cycle and Beam
positioning, these chapters provide a global overview and show
many details about the relations between the various parameters. Note that this document is not intende d as a start-up instruction guide
or user operation manual. The main purpose of this document is to describe the function of the parameters, their limit values as well as the default- and usual values. For a number of beam parameters, a basic adjustment procedure is given, and in some cases also details about the relation to other parameters. Refer to the specific documentation for information about start-up procedures, programming of the DNC, etc.

BEAM PARAMETERS

HYDRAULIC SYSTEMS

DIFFERENTIAL - AND COUNTER PRESSURE SYSTEM

The main types of hydraulic systems used for press brakes are the differential system and the counter-pressure system.
The differential system was the first s ystem used. In this configuration, the oil from the bottom side of the cylinders is fed to the top side. This helps to fill the top side during the fast approach, and increases the bending speed at the expense of a reduction of the bending force. The differential system requires a minimum pressure (giving a mi nimum bendi ng force) during bendi ng t o avoid overspeeding, and is no longer used for new machines.
In the counte r-pressure configuration, the oil from the bottom side flows through a pressur e relief valve to tank during the bending operation. This is the most common system in use now. When the counter pressure is set correctly, overspeeding during bending is not possible. Note that although not required to avoid overspeeding, a minimum system pressur e (giving a mi nimum bending force) is required for proper BDC closed loop position regulation.

PRESSURE BALANCE

The hydraulic system can be equipped with a pressure balance system. The purpose of this system is to keep a constant, low pressure drop across the proportional valves by automatic limitation of the system pressure. Some pressure balance systems are only active during the return movement of the beam; others are also active during the bending cycle. Because of the automatic pressure limitation, the pressure balance system makes it more complicated to set the pressure parameters. In most cases, the effective pressures set by the pressure parameters can only been seen when the ram movement is obstructed (end of stroke of the cylinders, closed tools).
Note that an active pressure b alance system during the bending cyc le constitutes a second regulation loop. Especially during BDC regulation, this regulation loop may interfere with the position regulation loop of the DNC, and require adapting some parameters.

VALVE OVERLAP

The main types of regulation valves used for press brakes are valves without overlap (or zero overlap) and valves with a positive overlap. See the image below:
Zero overlap valves were commonly used in the past. At present, mainly valves with a positive overlap are used because these valves are cheaper and easier to integrate in a safety system. Because of the positive overlap, these valves can be more difficult to adjust and they usually require higher voltage settings than for zero ove rlap valves.
Throughout this document, the typical values for beam voltage parameters assume zero-overlap valves. Some valve amplifiers electrically compensate a positive overlap. In this case, the beam voltage parameters are very similar to the settings for zero overlap valves. A positive overlap can also be compensated by P20a, Min.
voltage Y1 - Y2. As a rule, the overlap is only partially
compensated. See the description of this parameter for further details. When the overlap is not or only partially compensated, the typical values shown in this document must, of course, be increased to account for the non compensated overlap. The required increase is typically 0.5 to 1V.

BEAM PARAMETERS

PRESS BRAKE TYPES

Two types of press brakes exist: downstroking and upstroking machines. The type of press brake can be selected by P62, Press, as Downstroke or as Upstroke.
For the downstroking machines, the lower beam is fixed. The upper beam moves down from TDC to BDC during the bend operation, and then returns back up to TDC.
For the upstr oking machines, the upper beam is fi xed. The lo we r beam moves up from BDC to TDC during the bend operation, and then returns back down to BDC.
Basically, all parameters are identical for both types. The main difference is the inversion of TDC and BDC in the parameter names. Also, a standard downstroking press does not require hydraulic pressure during the fast approac h closing movement, whereas the upstroking press brake requires system pressure to lift the lower beam. For the opening movement, the pressure requirements are, of course, inverted. Further, the i ndexatio n cycle of the b eam is different for the two types.
Unless specifically stated, a downstroking type press brake is assumed throughout this document.

When the mode on the electrical panel is set to Sensitive
and the mode on the DNC to Semi-Auto or Automatic
, the beam will stay in BDC as long as the down command is maintained by the operator, and the programmed dwell time is not taken into account. The ram only returns to TD C when an up command is given by the o perator.
When the mode on the electrical panel is set to Sensitive
and the mode on the DNC to Semi-Auto the position of the beam can be adjusted under pressure using the + and – keys:
or : Adjusts the beam position by ±5 measurement increments (corresponds to ± 0,05 mm with an encoder resolution of 200 I/mm) at each key-press.
or : Adjusts the beam position by ±1 measurement increment (corresponds to ± 0,005 mm with an encod er resolution of 200 I/mm) at each key-press.
If the manual buttons are maintained pressed more than 2 sec. the beam will co ntinusely move slowly up or down.
The adjustment of the BDC under pressure is especially useful to optimize the BDC position for semi-bottoming or hemming bends as well as to determine the BDC for operations such as material marking or punching with special tools.
After adjustment, once the beam has returned to TDC, the final BDC can be copied to the current bend sequence using the actio n Teach.
For a DNC 60 or similar control, the key is used to teach the final BDC position.

CLOSED LOOP MODES

Depending on machine- and safety requirements, the DNC must react to an interruption of the machine cycle in differ ent ways. In some configurations, the beam must automatically return to TDC, while in other configurations t he beam should remain at the current position. In some situations, the beam should keep its current position under pressure, while in other cases the safety requirements do not allow this. Machine- and safety requirements also determine the appropriate decompression cycle and the type of slow speed return of the beam.
The machine parameters P01, Closed loop, and P41, Return TDC
Safety, and the input Permanent regulation determine how the
DNC reacts to interruptions of the machine cycle as well as the type of decompression cycle and slow speed return of the beam.
When the be am is in TDC o r when the down movement is interrupted, the following situations occur:
• Beam in TDC
When the beam has normally reached TDC, the DNC will keep the beam in position with TDC regulation. In this mode, the DNC will automatically move the beam back up, when it has dropped down too much below the TDC (because of some leakage in the cylinders or in the hydraulic system). The limit distance can be adjusted by P52, Ram regulation distance at TDC.
Throughout this document, this type of regulation is referred to as
TDC regulation.
Down movement interrupted above the safety point
In this case, P41, Return TDC Safety determines if the beam will automatically return to TDC or stay at the current position.
When set to Yes or when set to External mode and the electrical panel is not in Sensitive mode, the beam returns to TDC.
Otherwise the beam stays at the current position and the setting of P01, Closed loop, determines if this position is regulated by the DNC. When set to 0, the DNC will not regulate the beam position. Otherwise, the DNC will mainta in the current position as in TDC.
• Down movement interrupted below the safety point
In this case, the beam will stay in the current po sition. When P01, Closed loop, is set to 0, the DNC will not regulate the beam
position. Otherwise, the input Permanent regulation determines how to
regulate the beam position. When the input Permanent regulation is active, the beam is
kept in the current position with reduced pressure and BDC closed loop position regulation. This means that the SNY and PVY enable signals as well as the pressure - and proportional valves remain active.
V-DOC-PMPS2EN_V5 93
BE AM MO DE S
Throughout this document, this type of regulation is referred to as
BDC closed loop regulation.
Note that the hydraulic system must remain in bending configuration during the BDC clos ed loop regulation while the operator has released the down command. Safety regulations usually do not allow this and restrict the use of the BDC closed loop regulation. When using a foot pedal, a possible compromise is the use of a pedal with an intermediate position. In the intermediate position, the down command is released, while the input Permanent regulation is active, and the hydraulic system maintains the bending configurat i on. In this case, the BDC closed loop regulation is active. When the pedal is fully released, the input signal Permanent regulation is switched off. This will switch off the BDC closed loop regulation, and no longer require the hydraulic system to stay in the bending confi guration.
When the input Permanent regulation is not active, the beam keeps the current position using T DC regulatio n.
When the input Permanent regulation is switched from active to not active (switched off), the BDC closed loop regulation is switched off. This will also switch off the SNY and PVY enable signals and the pressure - and proportional valves. The beam continues to keep the current p osition using TDC regulation.
When the input Permanent regulation is switched from not active to active (switched on), the TDC regulation is maintained. The BDC closed loop regulation is o nly activate d when interrupting the down command below the safety point as long as the input Permanent regulation is active.
V-DOC-PMPS2EN_V5 94
BE AM MO DE S
The closed loop modes can be summarized as follows:

TDC REGUL ATION MODE

In this mode, the beam is ke pt in positi on with TDC regulatio n. The DNC will automaticall y move the beam back up, when it has dropped down too much (because of some leakage in the cylinders or in the hydraulic system). The limit distance can be adjusted by P52, Ram
regulation distance at TDC.

BDC CLOSED LOOP REGULATION MODE

In this mode, the beam is ke pt in the current position with reduced pressure and BDC closed loop position regulation. This means that the SNY and PVY enable signals as well as the pressure - and proportional valves remain active .
This mode requires that all of the followi ng conditions are met:
P01, Closed loop is set to 1 or 2
Input Permanent regulation is active DNC operating mode is (semi) a utomatic Beam is at or below the safety point
If any condition is no longer met, the regulation mode reverts to TDC regulation. Note that the DNC will not switch from TDC regulation mode to BDC closed loop regulation mode.
V-DOC-PMPS2EN_V5 95
BE AM MO DE S

DECOMPRESSION MODES

After reaching the BDC, or when the down move ment is interrupted below the safety point, a decompression cycle is performed prior to starting the return to TDC. The purpose of this decompression cycle is to reduce the (high) pressure on the top side of the cylinder prior to opening the prefill valves. This avoids a decompression bang due to the opening of the prefill valves under pressure.
On many systems, the prefill valves open automatically when the enable signals SNY and PVY for the down movement are switched off. In this case, especially when the prefill valves open fast, a decompression bang can occur.
On other systems, the prefill valves are always open in one direction allowing to fill the top side of the cylinder. In the other direction, from the cylinder to tank, these valves remain closed unless a pilot pressure is applied to open them. In this case, the prefill valves remain closed when the ena ble signals SNY and PVY for the down movement are switched off (and no decompression bang will occur). The pilot pressure to open the prefill valves is applied when starting the normal return to TDC (when the enable signal SPY is switched on).
Depending on the operating conditions, the decompression will be carried out in one of the following modes:

RETURN MODE (OPEN LOOP MODE)

This mode is used when P01, Closed loop, is set to 0, or when the input Permanent regulation is not active. Note that once active, this mode remains active even when the input Permanent regulation is activated.
In this mode, the enable signal SPY is output as for the normal, high speed return. During the decompression time, the regulation valves are set according to P25, Voltage decompression, and the system pressure valve is set to P36, Pressure decompression. Note that the prefill valves will open at the start of the decompression cycle. The opening speed of these valves should be restricted to avoid a decompression bang.

BENDING MODE (CLOSED LOOP MODE)

This mode is used when P01, Closed loop, is set to 1 or 2, and the input Permanent regulation is active. Note that the mode will switch to return mode (open loop mode) when the input Permanent regulation is deactivated.
In this mode, the hydrau lic system remains in the bending configuration, and the prefill valves remain closed. The DNC tries to move the beam up with the speed set in P13, Max bending speed
. The settin g of the regulation valves is limited to the voltage of
V-DOC-PMPS2EN_V5 96
BE AM MO DE S
P21, LS voltage , and the system pressure valve is set to P36, Pressure decompression.
The prefill valves will open after the decompression cycle. A decompression bang will not occur, provided that the pressure on the top side of the cylinders has sufficiently decreased during the decompression cycle.
The closed loop decompression mode provides optimum decompression control. Note, however, that the hydraulic system must remain in be nding confi guration d uring the decompression, also when the operator releases the down command. Safety regulations usually do not allow this and restrict the use of the closed loop decompression mode. In some cases, the SPY enable signal can be used instead of SNY to differ entiate between bendi ng and decompression, resolving the safety restriction. See P01, Closed loop.
Alternatively, the inp ut Permanent regulation can be active as long as the operator maintains the down command. While this is the case, the closed loop decompression mode is permitted. When the down command is released during the decompression, the decompression mode will switch from closed loop to open loop mode. In many cases, this is an acceptable compromise.
V-DOC-PMPS2EN_V5 97
BE AM MO DE S

SLOW RETURN SPEED MODES

The operator can program a slow speed return from BDC to the pinch point or during a part of this distance. After the slow speed return, the DNC switches over to the normal return speed.
Depending on the operating conditions, the slow speed return will be carried out in one of the following modes:
REDUCED RETURN SPEED MODE (OPEN LOOP
MODE)
This mode is used when P01, Closed loop, is set to 0, or when the input Permanent regulation is not active. Note that once active, this mode remains active even when the input Permanent regulation is activated.
In this mode, the enable signal SPY is output as for the normal, high speed, return, and the prefill valves are open. Very slow beam speeds are critical and instable in this hydraulic configuration. Therefore,
P20b, Final approach voltage , is used to set the reduced speed
of the beam, irrespective of the slow return speed programmed by the operator.
Note that with high return forces (spring l oaded punching tools , adiprene dies, high springback material, etc.), the return force may be sufficient to lift the beam at a high speed. In this case, the beam movement cannot be controlled by the DNC, because the prefill valves are open and the oil can freely flow from the top side of the cylinders t o tank.

BENDING SPEED MODE (CLOSED LOOP MODE)

This mode is used when P01, Closed loop, is set to 1 or 2, and the input Permanent regulation is active. Note that the mode will switch to reduced return speed mode (open loop mode) when the input Permanent regulation is deactivated.
In this mode, the hydrau lic system remains in the bending configuration, and the prefill valves remain closed. The DNC moves the beam up with the speed set b y the operator. The maximum speed
is defined by P13, Max bending speed , and the setting of the regulation valves is limited to the volta ge o f P21, LS voltage .
Note that the speed during the decompression is the slow speed set by the operator instead of the maximum speed.
Compare to bending, the slow return speed requires a (much) higher output voltage to the regulating valves. The high cylinder surface ratio requires this in order to achieve a sufficiently low pressure at the top side of the cylinders.
V-DOC-PMPS2EN_V5 98
BE AM MO DE S
The closed loop decompression mode provides optimum slow speed control. Note, however, that th e hydraulic system must remain in bending co nfiguration during the slow speed return, also when the operator has released the down command. Safety regulations usually do not allow this and restrict the use of t he c losed loop slow return mode. In some cases, the SPY enable signal can be used instead of SNY to differentiate between bending and slow speed return, resolving the safety restriction. Se e P01, Closed loop.
Alternatively, the inp ut Permanent regulation can be active as long as the operator maintains the down command. While this is the case, the closed loop slow speed return mode is permitted. When the down command is released during the slow speed return, the DNC will switch from closed loop to open loop mode and continue the slow return as a normal return with a reduced speed. In many cases, this is an acceptable compromise.
