• one analog output signal. The type of control can be specified as on-off control. When there is a position error, the control signal is on. When there is no position error, the control signal is off. • 1-speed AC axis For a 1-speed axis, the parameter 'axis type' must be set to 1.
Page 31
Delem speed for the axis movement. As with the 1-speed axis, the parameter 'Stop time' (T) can be used to improve positioning. If the analog output is used for axis control, the parameters 'DC high speed' and 'DC low speed' must be programmed at two different values. These values determine the voltage levels at the analog output for the two different speed settings.
Bipolar: Unipolar: A unipolar system can be implemented for servo and AC drives. 1.3. Spindle correction table The spindle correction table is meant to overcome axis position errors due to mechanical inaccuracies in the spindle. If a spindle shows deviations then they should be measured systematically on certain setpoints.

Page 35
Delem When this parameter is set to 1 (default value), all operation modes are available for the operator. When set to 0, the operation modes “Programming” and “Program selection” are not available for the operator. The other modes will remain available. The tabs of these remaining modes are aligned to the left in the Navigation bar.
2.2. Backgauge control parameters Parameter 19 Control type Range : 0 - 3 Unit Default Function The type of motor system that is to be controlled. 0 = No control 1 = 1-speed AC or DC drive 2 = 2-speed AC or DC drive 3 = Servo motor drive According to this setting, parameters for Servo or for AC will appear for programming.
Page 37
Delem Unit : mm Default : 1000.00 Function Maximum backgauge position. The axis will never be controlled to a higher position than programmed here. Parameter 23 Manual speed high Range : 1 - 100 Unit Default : 50 Function Speed of the axis, when it is moved in manual mode with the ‘manual move’ function. This is the travel speed when the arrow key is pressed continuously.
Page 38
Parameter 26 Enable display correction Range : 0 - 1 Unit Default Function When the axis reaches the programmed position, the display can show the real measured position or it can show the programmed position. This can be programmed with this parameter.
Page 39
Delem Unit : counts/mm Default : 50.000 Function Sets the scaling between encoder pulses and millimeters. The encoder gives an exact number of count pulses over a mm displacement. This value must be programmed here. The value can be calculated by the formula:...
Page 40
Function To choose whether or not to have a reference search cycle at start-up of the control. 0 = no reference search at power-on 1 = reference search If programmed to 0, the control memorises the position when switched off. During operation, the actual position of the axis can be programmed with a parameter in the Program Constants, ‘Actual X position’.

Function When set to 1, the retract function is enabled. Several parameters (37-40) will become available and can be programmed. Parameter 37 Auto retract enable Range : 0 - 1 Unit Default Remark Only if ‘Retract programmable’ (36) is set to 1. Function When set to 1, retract is automatically started on the high-to-low transition of the input ST, which is the moment to start cutting.

Delem Range : 0.0 – 9999.9 Unit : mm Default : 0.0 Remark Only if ‘Retract programmable’ (36) is set to 1. Function Default value for the retract distance when a new program is created. Parameter 41 Safety Zone Range : 0.0 –...
Page 44
Function Overrun distance in case of one side positioning. One-side positioning is chosen with the parameter ‘spindle allowance’(42). An overrun is also done when an AC-drive must change position over a small distance, smaller than BLS(55). If such a situation occurs, the axis is first moved to the overrun position and then back to the required position.
Page 45
Delem If the X-axis position is smaller than X-limit, the X-axis moves at normal speed. If the X-axis position is larger than X-limit, the X-axis moves at the speed, as programmed at ‘Limit speed’(47). Parameter 47 Limit speed Range : 0.0 - 100.0...
Page 46
Only if ‘Control type’ (19) is set to 3. Function This is the nominal deceleration of the axis, used to control the axis from maximum to zero speed when the axis comes into position. This parameter must be programmed as the time in which the axis decelerates from maximum to zero speed.

Delem Switch point from high speed to low speed in the upcounting direction. Parameter 60 Stop time Range : 0 - 9999 Unit : msec Default Remark Only if ‘Control type’ (19) is set to 1 or 2. If ‘AC brake enabled’ (54) is set to 1, this parameter is not available.
Page 50
Range : 1 - 100 Unit Default : 80 Remark Only if ‘Control type’ (19) is set to 2. Function This is the output voltage for high speed movement in the negative direction. This parameter must be programmed if a 2-speed DC motor drive is controlled with the analog output. It is programmed as a percentage of the maximum output voltage (10 V).
Delem Only if ‘Control type’ (19) is set to 1 or 2. Function The nominal deceleration time, in which the axis decelerates from high speed to low speed. This parameter must be programmed if 2-speed DC motor drives are used.
Page 52
Range : 0.0 - 45.0 Unit : degrees Default : 0.0 Remark Only if the parameter ‘control enable’ (68) is set to 0. Function If there is no angle control, the (fixed) angle of the cutting blade can be programmed with this parameter.
Page 53
Delem The value is programmed in AD-points: a converted digital value of the position feedback voltage of the potentiometer. Parameter 73 Angle prestop negative Range : 0 - 99 Unit : AD value Default Function This parameter has the same definition as parameter "Angle Prestop Positive" but only in the negative direction of the angle adjustment (smaller angle).
Unit Default Function Press ENTER to open the screen with the angle material table. In this table the cutting angle can be programmed as a function of sheet thickness and sheet material. If this table is programmed, the angle is precomputed for each cutting step in a program.
Page 55
Delem Unit : AD value Default Function Due to the inertia of the Gap system there can be some overshoot after the control output has been switched off. To prevent such overshoot, the 'Gap prestop' can be programmed. This parameter can be regarded as a programmable offset. The control will take this offset into account when positioning the Gap.
Page 56
Gap: program a known gap value for the blade. AD-value: program the required feedback voltage for this gap. The voltage must be programmed in the range 0-4095, it will be converted to an input voltage in the range 0-10V. The adjustment procedure to find the correct AD-values is similar to the procedure for angle values as described in the previous section.
Page 57
Delem The sheet thickness is indicated in the vertical column, as a percentage of the maximum thickness (parameter 13, ‘Maximum thickness’). For various plate thickness values, the required gap value can be programmed. These setpoints can be programmed for each material (column M1-M6).
Press ENTER to open a screen with the gap2 reference table. See parameter ‘Gap reference table’ (79) for more information. 2.5. Stroke control parameters Parameter 85 Stroke mode Range : 0 - 2 Unit Default Function 0 = No stroke option (‘Stroke length’ not available in user interface) 1 = Stroke length using timer 2 = Stroke length using analog feedback (using input ‘SFB’) In case of 1and 2, the following I/O an be used:...
Page 59
Delem Range : -999 - 0 Unit : mm Default Remark This parameter must be programmed when ‘stroke mode’ is set to 1. Function This is the stroke distance when the blade is positioned on the upper dead point. Stroke...
Page 60
Stroke: program a known stroke value for the blade. AD-value: program the required feedback voltage for this stroke. The input voltage must be programmed in the range 0-4095, representing an input voltage in the range 0-10V. The adjustment procedure to find the correct AD-values is similar to the procedure for angle values as described in section 2.5.
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.
Page 62
Cut: program a known force value (in kiloNewtons) for a cut. DA-value: program the required output voltage for this force. The output voltage must be programmed in the range 0-4095, it will be converted to an output voltage in the range 0-10V. Parameter 96 Main force ramp Range...
Page 63
Delem This is the time the output B_UP must remain active after UDP has been reached. Parameter 99 Opening force Range : 0 - 100 Unit Default : 50 Function The force for steering the blade up. This value is programmed as a percentage of the maximum force (as programmed in the reference table).
Page 64
Force value for the main force during clamping. It is programmed as a percentage of the maximum main force. Parameter 103 Clamping force delay Range : 0 - 9999 Unit : msec Default Function Delay before the output is controlled for clamping. Parameter 104 Clamping time Range...
Page 65
Delem Parameter 107 Clamping force delay Range : 0 - 999 Unit : msec Default Function After the ‘ST’ input goes low, the control will start force control. This parameter can be used to program a delay before force control is started.
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.
Page 67
Delem Each choice opens a sub-menu with an array of the logical signals and available connector pins. The screen for digital inputs looks as follows: In the top row, the available connector pins are shown. In the left column, the logical signals are listed.
3.2. List of I/O signals Digital input signals Code Name Description UDPIN UDP input Input to indicate blade is in the mechanical Upper Dead Point. Machine Ready Signal that indicates the machine is ready. When it is low, the control cannot be started and digital outputs and pressure outputs are disabled.

• Delem back-up software for transmission of machine settings. The Delem back-up software must be installed on the PC. All actions, storage and restoration of settings, are done with this program. Just make sure the necessary cables are connected and the DAC control is switched on.
Page 72
After start-up, the two large buttons for back-up and restore cannot be selected yet. First, click on the button ‘Connect...’ to establish a connection between the software and the DAC control. If not succesful, select a different serial port (COM1, COM2, etc.) and try again. If this still gives no positive result, check your cabling.
PC (COM1). You also need a program that will load the new software into the control. This program can be requested from Delem. Note: before starting an update, first perform a back-up of your control settings. When the control is updated, all data is erased and the control is reset to factory default settings.
4.3. Special access codes There are several access codes to enter special menus of the control. These access codes should only be known and used by authorised service personnel. Each code is entered on the page of the program constants, when the cursor is on the parameter Language.
Delem 4.4. Display codes In the upper richt corner of the screen, a status code is shown that indicates the current status of the control. Such a code can either be a status code or and error code. The following table shows the possible status codes:...
Introduction 1.1. Remarks With the test functions of the diagnostic program a service engineer can test the control and the interfacing with the system. Before starting the diagnostic program it is wise to check the machine for moving parts. This is because during the diagnostic operation of the control no regulation of the axis is performed.
