  Delem Due to the inertia of the system it is possible that the shear has a slight overshoot when it is stopped at the computed value. The programmed ‘prestop’-value is subtracted from the computed value, creating an EOS (end of stroke) output signal at an earlier moment than the programmed moment.

  I/O assignments 3.1. Inroduction The control has several programmable features. These features can be enabled or disabled in software. Depending on these featues, a number of logical signals can be mapped to the I/O pins of the control. This means the system programmer can enable the necessary signals and assign them to output pins.

PREFACE

In this machine parameter manual you find the explanation on:

•the input and output signals (X- and Y-axis and general);

•the selection possibilities of the machine parameter menu;

•the value and function of the machine parameters of the X- and Y-axis;

•the auxiliary axes with corresponding parameters.

The first chapter describes the function of the general input and output signals and the input and output signals of the X- and Y-axis and in what way these signals should be connected to the axis module.

The High Speed Bus (HSB) takes care of the communication between the control and the modules. Via this HSB line the modules are programmed with the appropriate machine parameter values to control the axes. The programmed values of the axes are compared with the actual axes positions and the machine parameter settings. If the ‘new’ values are within the range the ‘new’ values become the actual values.

The machine parameters (including all axis parameters) are programmed in the machine parameter menu of the control. Besides the programming of the machine parameters you have several other selection possibilities in this machine parameter menu. These selection possibilities are explained in chapter 2.

The basic machine parameters are to control the Y-axis. In chapters 3 and 4 these machine parameters are explained. The explanation comprises the parameter range, the default value, the parameter function and a description.

From chapter 5 until chapter 10 the parameters of the auxiliary axes and special functions are given. The auxiliary axes are grouped per type of axis. The next type of axes and special functions are explained:

auxiliary axes (chapter 5);

axes types and parameters (chapter 6); crowning (chapter 7);

digital outputs (chapter 8); I-axes (chapter 9);

part support (chapter 10);

1.Input and output signals

1.1.Introduction

In this chapter the input and output signals of the Delem system are explained. See the installation manual of the control for the locations of the various connectors.

There is a strong relation between the Y-axis signals. This relation has been laid down in the timing diagram of the press cycle.

The timing diagram of the CNC-RDY signal has also been included. This signal indicates that the active bend program can be executed. The CNC-RDY signal depends on the status of the start button, the position of the Y-axis and the position of the X-axis.

1.2.Y-axis input signals

1.3.Y-axis output signals

1.a

The braking ramp for stopping at the optional muting point is computed automatically by the control. The distance between the two muting points is programmable, the default value is 0 mm. This means that the two mute outputs become active at the same time.

1.b

The point at which the optional mute output becomes active can also be shifted with an offset. This offset does not shift the computed braking point. It can be programmed with the parameter “Offset mute-2 output”. The default setting is 0.

Clamping (pinching) point output. This output becomes active when the beam reaches the clamping (pinching) point and stays active as long as the beam is below the clamping point.

Lower dead point output. This output becomes active at the end position of the press beam. This output is active during Y-axis status 4.

1.4.X-axis signals

1.5.Axis signals

1.6.Various input and output signals

FUNCTION OUTPUTS

F1, F2, F3, F4 These are general purpose outputs. When you use a motorized crowning unit then outputs F3 and F4 are not available, because they are reserved for crowning usage.

If the control is in manual mode the same conditions apply, except in manual mode the UDP signal is not necessary for the CNC-RDY.

Explanation of CNC-RDY timing diagram

•Y-axis status. The Y-axis status is the number of the Y-axis control program, which depends on the Y-axis command inputs. The number is shown on the service row (when activated) in the header of the screen.

•Upper dead point. Y-axis output indicating that press beam is in the upper dead point position.

•X-axis at programmed position. This line shows the actual X-axis position. This is the same as the programmed position.

The start button must be pressed (1). When in this case the press beam is in the upper dead point (output active) and the X-axis reaches the programmed position (2) the CNC-RDY output becomes active (3). The CNC-RDY output stays active during fast closing of the press beam (4), pressing (5) (when no X-axis retraction is programmed), dwell time (6) and decompression (7).

The CNC-RDY becomes inactive after decompression of the beam (ER output active) at the step change position where the X-axis moves to the next programmed position. Depending on the Step change code this can take place at:

•end of decompression;

•mute (passed in opening direction);

•upper dead point.

The CNC-RDY signal becomes active again (9) when the X-axis is at its programmed position and the Y-axis is in the upper dead point.

CNC-RDY signal during pressing with retraction programmed

There are two situations during pressing with rectraction programmed (point 5 of CNC-RDY cyclus).

•The press beam does not wait at the pinching point for X-axis retraction to complete (“Wait for retract” is off). The CNC-RDY output stays active while the X-axis moves to the retract position.

•The press beam stops at the pinching point and waits until X-axis retraction is completed (“Wait for retract” is on). The CNC-RDY output stays active while the X-axis is moving to the retract position. The press beam moves again when the X-axis has reached the retract position.

There is also a third situation, but this is an option.

•The press beam stops at the pinching point and waits until the X-axis rectraction has been completed (“Wait for retract” is on). The CNC-RDY output is off while the X-axis is moving to the retract position. The CNC-RDY output becomes active again when the X- axis has reached the retract position.

1.7.Conventional systems

Beside controls for synchronised Y-axis control, there are also Delem controls for conventional pressbrake machines. These controls have a different set of machine parameters for Y-axis control. The use of some parameters is related to the equipment that is installed.

1.d

•YM-axis

A mechanical stop for the Y-axis can be programmed as an auxiliary axis (axis type YM). This axis is controlled through the circuitry for Y1: the valve voltage output is used to control the motor, the encoder input for Y1. The YM axis is programmed as a standard auxiliary axis. On a DAonWindows control this auxiliary axis must be assigned to the Y-axis module. The parameters for this axis are all standard servo parameters, which are described in chapter 5.

•Pressbeam position feedback

A conventional pressbrake machine can be equipped with a linear or rotary encoder scale for position feedback.

If no linear scale is used, positioning of the pressbeam must be arranged externally. In that case, a switch for ‘step change’ must be installed to signal to the control that a bending has been carried out and the next step can be done. If the retract function is necessary in the machine, a switch for a ‘retract request’ must be installed.

If a linear scale for position feedback is installed, these switches are not necessary. The control can use the position information to generate a retract and a step change. Whether or not positioning control is used is programmed with the parameter «Encoder mounted».

See section 4.12 for more information about conventional parameters.

2.Machine parameters menu

2.1.Introduction

In this chapter the selection possibilities of the machine parameters menu are explained. The next selection possibilities are discussed:

•selection procedure machine parameters menu (section 2.2);

•a brief introduction on the Y-axis and general parameters (section 2.3);

•a brief introduction on the auxiliary axes (section 2.5);

•notes about module configuration and module software (section 2.6);

•machine parameters backup procedure (section 2.7);

•changing the access code (section 2.8);

•viewing options (section 2.9).

2.2.Selection procedure of machine parameters menu

The selection procedure of the machine parameters menu is the same for each type of control of the DAonWindows series.

Do the following to get access to the machine parameter menu:

•Select the programming mode.

•Enter 19 to select the machine parameter menu.

•Enter the access code.

•Press the enter key.

The default access code is 14753 for changing a basic set of machine parameters. The machine parameters followed by (2) cannot be changed with this code. When you want to change all the machine parameters you require the special factory code. This code may only be used by authorised people.

There is a third access code available, which gives access to a third level of parameters. Normally these parameters are set to factory default values and need no adjustment. In order to view and adjust these parameters, you need to enter the menu with a level 3 access code. You will see additional parameters, which are followed by a (3). This code may also be used only by authorised people.

In the machine parameter main menu you also find the versions of the current KO-table and the sequencer file. For detailed information upon the KO-table and Sequencer file version please contact Delem.

In figure 2.a you see the main machine parameter menu of the control.

2.a

2.3.General parameters

Behind this selection possibility you find the basic machine parameters to program the press brake specifications, such as dimensions. See chapter 3 for full explanation upon the parameters.

2.4.Y-axis parameters

Behind this selection possibility you find the machine parameters to control the Y-axis. See chapter 4 for full explanation upon the parameters.

2.5.Auxiliary Axes

Per type of control you can activate a number of auxiliary axes. An auxiliary axis is not active when it is disabled in the axes menu. The required function of an auxiliary axis is determined by the axis type.

Based on the available types the chapters 5 until 9 have been defined. In these chapters you find explanation on the parameters in more detail.

To install auxiliary axes, three steps must be taken:

•the modules must be selected through menu 4: ‘module configuration’,

•the configuration of backgauges must be programmed through menu 8: ‘gauge’,

•the intended axes must be programmed through menu 3: ‘auxiliary axes’.

See chapter 5 about auxiliary axis configuration.

2.6.Module configuration

This function serves to select the connected modules in the system and assign the proper axes to those modules.

Chapter 5 contains a detailed description of module configuration. This should be done first, because otherwise no axis can be controlled.

Modules can be upgraded with new software. The procedure to upgrade a module is explained in chapter 5.

2.7.Machine parameters backup

2.b

It is very important to make a backup of the machine parameters each time they have been changed.

Function keys:

2.8.Changing the access code

You can change the access code of the machine parameters menu. The procedure is as follows:

•enter old code;

•enter new code;

•(re)enter new code;

press the enter key to accept the new value.

Without the correct access code it is impossible to enter the machine parameters menu. Therefore, be sure if you want to change the default access code (14753).

2.9.Options

The standard functionality of the Delem control can be expanded with extra options. A new option can only be used when the option has been enabled in the control. If you wish to activate an option, contact Delem to obtain an option voucher.

Installation of options is described in the installation manual of the DAonWindows controls. The options with the √ — sign are already enabled in the control and can be used.

2.c

2.10.Gauge

In this menu the configuration of backgauges and auxiliary axes must be programmed. This programming facility offers a flexible way to describe the available backgauges and by which axes they are moved.

2.d

See chapter 5 for information about gauge programming.

2.11.Leaving the machine parameters menu

When leaving the machine parameters menu, beware of two things.

•The control checks if all programmed axes are properly assigned to DM modules. If this is not the case, the control issues a warning. See also chapter 5.

•If no machine parameter has been changed, the control returns to the main menu. If any parameter has been changed, the control will reset. If ‘enter’ is pressed while the cursor is on a machine parameter, the control will assume this parameter has been changed and will reset itself when the menu is left.

3.General parameters

3.1.Introduction

In this chapter the general machine parameters are described. Each parameter explanation comprises the following items:

•Parameter number. Each parameter has a unique number or code.

•Parameter name. Each parameter has a unique name.

•Range. The maximal value and minimal value that can be programmed.

•Default. The initial value of this parameter. This is also the value after an initialisation.

•Units. The unit of the parameter (s, mm, kg, DA-points, etcetera).

•Function. The function of the parameter.

•Description. Full description of the use and meaning of the parameter.

Standard all parameters are valid for all controls mentioned in this manual. If there are exceptions then this is indicated.

5 = Control waits until beam is at bending position, and decompression is completed

6 = Control waits until beam is at muting point after bending (in opening direction of beam) 7 = Control waits until upperbeam has moved from muting to UDP in opening direction

8 = Control waits in UDP until dwell time in UDP has been expired.

11= Wait until beam is in UDP in case of step-by-step mode when no auto-step-change is selected.

12= Waiting for C-input active in case step-change code CX = 4 or 5 is selected.

14 = Clamp is active, waiting until retract is finished. 20 = Waiting until all axes have been started.

50 = Sequencer functions are being excuted.

Note:

When an optional second servo axis is enabled, this will have consequences for cycle numbers -2, and -1:

-2 = Control waits until X-axis and second servo-axis references are passed. (e.g. X2or R- axis)

-1 = Control waits until X-axis and second servo axis are both in position, the beam is in UPD and the opening command is released.

When the second servo axis is configured as X2-axis also cycle number 4 is affected. 4 = Control waits until retraction of X-axis and X2-axis are both completed.

Description

During the development and testing of the sequencer file, it can be useful to read this file from an external device, without having to modify the existing application. This possibility can be selected by adjusting this machine parameter.

0 = using sequencer file from the internal application

1 = loading sequencer file from external USB device Press the key to select the required setting.

With this parameter set to 1 the sequencer file is only read from USB disk during start up.

After testing the sequencer file you should set this parameter to 0 again. Put all required sequencer files on the hard disk of the control and restart the control.

Note:

For more information about working with the sequencer file please refer to the sequencer manual. This manual can be requested at Delem.

Description

When the sequencer debug facility has been switched on (=1) a soft key appears in the manual mode. Activating this key will generate a test row on top of the screen. In this row you can check the equations of the sequencer. This test row overwrites the service row (in case the service row is active).

See also the Delem Sequencer manual for more information.

Parameter: KO

Select KO-table

Parameter: MN

Machine name

Range : —

Default : —

Units : —

Function

Name or description of the current machine. The maximum length is 25 characters.

Parameter: 54

Total machine length

Range : 0 — 15000

Default : 2000

Units : mm

Function

Total machine length for check in relation with the product length.

Description

When the operator programs a bending length longer than the programmed total machine length a warning appears on the screen.

Parameter: 50

Machine length between cylinders

Range : 0 — 15000

Default : 2000

Units : mm

Function

The length of machine table between the cylinders will be used to compute the table deflection.

Description

This parameter is used to compute the machine table deflection. The table deflection is only computed when a crowning adjustment device is connected. (See chapter 6).

You have to program the machine length between the mid position of the 2 cylinders. See also machine parameters ‘Inertia under beam’, and ‘Inertia upper beam’.

3.b

Parameter: 51

Inertia under beam

Function

The inertia of the machine table is used to compute table deflection.

Description

This parameter is used to compute the machine table deflection. The table deflection is only computed when a crowning adjustment device is connected (see chapter 6).

See also machine parameters ‘Machine length between the cylinders’ and ‘Inertia upper beam’.

Example

Inertia = 1349000

Program: 1349

Parameter: 52

Inertia upper beam

Function

The inertia of the machine upper beam is used to compute table deflection.

Description

This parameter is used to compute the machine table deflection. The table deflection is only computed when a crowning adjustment device is connected. (See chapter 6).

See also machine parameters ‘Inertia under beam’ and ‘Machine length between the cylinders’.

Example

Inertia = 1349000

Program: 1349

Parameter: 20

Relaxation Stiffness

Range : 0.000-99.900

Default : 0.300

Units : µm/kN

Function

Stiffness of frame used to compute decompression.

Description

The stiffness of the frame is used to compute the decompression distance. This value will be multiplied with computed force to obtain decompression distance.

Parameter: 21

Stiffness of frame

Range : 0.0-100.0

Default : 0.0

Units : %

Function

Stiffness of frame, used for Y-axis depth computation.

Description

When you program bending angles, the corresponding bending depth is computed automatically. Stiffness of frame is used to compute a correction for this bending depth due to the deflection of the frame.

The deflection compensation arm will not fully compensate the deflection of the side frame in order to compensate the Y-axis bend position. Bending the same metal with length of 0,5 meter must have the same angle when bending it with a length of 1 meter or longer.

The difference between the two bends is the tonnage. With 1 meter length the frame will deflect more because it requires more tonnage when bending 0,5 meter.

The value programmed for this parameter must be the deflection of the side frame which is not compensated by the compensation arm. This value is programmed as a percentage of the value programmed for the machine parameter ‘Relaxation Stiffness’.

Parameter: 7

Tool Reference

Range : 0.00-9999.99

Default : 320.00

Units : mm

Function

The machine opening between upper beam and table.

Description

This is the opening between upper beam and table when the Y-axis is at zero. This value is used in the computation of the bending depth, mute point and clamping point.

3.d

Parameter: TR

Tool Reference correction

Range : 0.00-9.99

Default : 0.00

Units : mm

Function

A correction of the Tool Reference value for head mounted punches.

Description

The control can make a distinction between ‘head mounted’ punches and ‘shoulder mounted’ punches.

In case of a shoulder mounted punch (default situation), the control uses the Tool reference and the Tool height to compute the correct Y-axis position. Since the Tool height is measured from the punch’ shoulder, this leads to accurate positioning.

In case of head mounted punches, the punch’ shoulder might not correspond with the lower edge of the pressbeam. In that case, the position of the Y-axis is no longer accurate.

3.e

In such case, a correction of the Tool Reference value can be programmed.

The Tool reference correction is only taken into account, when a head mounted punch is used in a bend program. Otherwise, it is ignored. The type of punch can be programmed at the punch parameters in programming mode:

3.f

0 = shoulder mounted (default)

1 = head mounted

3.g

Parameter: 55

Punch clamp pressure

Range : 0-255

Default : 0

Units : DA-points

Function
