Part II - Machine parameters
This section will describe the necessary settings of a DAC-310 control regarding machine
settings.

Delem
V1204, 2.2
1. I/O assignments
The DAC-310 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 DAC.
This means the system programmer can enable the necessary signals and assign them to
output pins. The I/O settings are only accessible with a special entry code. It should be
adjusted by authorized personnel only.
Example:
1 2 3 4 5 6 7 8
RDY
EOC
EOS
++
+
-
--
The example picture above shows an example of a possible mapping of output pins. In the
picture, pins 5 - 8 are allocated for the movement of a 2-speed AC drive, fast and slow in both
directions. If the system has a servo drive, those signals are not necessary. Then you could
delete these connections (the intersections) and use output 5 - 8 for other pusposes.
See also the schematics in part I of this manual for connection examples.
To enter the I/O allocation mode:
• move the cursor to the M parameter;
• type access code 963 and press ENTER.
The following screen appears:

Delem
V1204, 2.3
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 (D1 - D4) are shown. In the left column, the
logical signals are listed. The symbol indicates that there is a connection between the pin
and the logical signal. A signal is linked to an input pin as follows:
• move the cursor with the arrow keys and +/- keys to the necessary intersection
• press ENTER
To erase a connection, go to it with the cursor and press ENTER. The connection will
disappear.
D1 - D4 refer to the 4 digital inputs of the DAC. ‘0’ is a logical FALSE. If a signal is linked to
this, it is always regarded as low (not active). ‘1’ is a logical TRUE. If a signal is linked to
this, it as always regarded as high (active).
For digital outputs the method works similar. In the case of outputs, several logical signals can
be mapped to the same output pin. They are processed as a logical OR: if one or more of these
signals become high, the output pin becomes high.

ST Start Enable External start signal, used to start axis movement and
change step.

reference switch is used.

MR Machine Ready Signal that indicates the machine is ready. When it is
low, the control cannot be started. When it is high, the
control can be started and the Hours counter (parameter
91) keeps track of the time.
Digital output signals
Code Name Description
RDY Ready Ready signal, to indicate that control has finished
positioning. In case of a shear system, this signal
becomes high when the axis is in position and the Gap
is set correctly.
EOC End Of Cycle Program or step is finished
EOS End Of Stroke Stroke is finished, either position is reached or stroke
time has elapsed
F1 Function output 1 General purpose programmable output
F2 Function output 2 General purpose programmable output
G+ Gap open Increase gap opening
G- Gap close Reduce gap opening
A+ Angle increase Increase angle between table and shear
A- Angle decrease Reduce angle between table and shear
+ Opening Opening command for AC motor
- Closing Closing command for AC motor
++ Fast opening Fast opening command for AC motor
-- Fast closing Fast closing command for AC motor
BRK Brake (AC) Brake signal for AC motor, equipped with brake
system. This signal is ‘low-active’: during positioning
the signal is high, it will become low when the brake
must be applied.
Analogue input signals
Code Name Description
SFB Stroke Feedback Position feedback of the shear, in case Stroke feedback
is enabled.
GFB Gap feedback Position feedback of the Gap opening, in case Gap
system with position feedback is enabled.
PFB Position feedback Position feedback of axis position.
AFB Angle feedback Feedback of angle value, in case angle control is
installed.
Note:
The encoder input is also regarded as an analogue input.

SPD Speed Speed output.
SPD > 0: positive direction, encoder upcounting
SPD < 0: negative direction, encoder downcounting

2. The machine parameters
2.1. The menu
The machine parameters are only accessible with a special entry code. Machine parameters
should be adjusted by authorized personnel only. To enter the machine parameters menu:
• scroll to the M field
• enter the code 8520
• press ENTER.
Now you can change the machine parameters of the control.

2.3. Drive types
The DAC control can be programmed to drive different axis types:
• 1-speed AC or DC drive
• 2-speed AC or DC drive
• Servo motor drive
The required system can be programmed with the parameter ‘Drive type’.
2.3.1. Servo drive
The following servo parameters are valid:
• Servo gain
• Servo switch
• Servo Ramp
• Servo acceleration
Inside the switch zone the Gain is active and outside the switch zone the Ramp is active. See
the Axis parameters ‘Gain’, ‘Switch’ and ‘Ramp’.

The optimal values for these parameters can be found by the following procedure:
• Increase the Ramp (point by point) until the axis has overshoot at the programmed end
position, substract 1.0 from this value and program this for the Ramp.
• Increase the Gain (point by point) until the axis starts to oscillate at the programmed end
position, substract 1.0 from this value and program this for the Gain.
The Ramp should be smaller than the Gain.

V1204, 2.9
2.3.2. AC drive
In this paragraph, the parameters for axes with AC drives are discussed.
When using AC drives, it is possible to program 1-side positioning or 2-side positioning.
Beside this, it must be indicated whether a one-speed or 2-speed motor drive is used.
With these parameters you can optimize the positioning accuracy of the AC-axis:
• Breakpoint high speed (BFS)
• Breakpoint low speed (BSS)
• Overrun (OR)
• Overrun wait time
• Stop time (T)
• DC slow speed
• DC fast speed
For the movement control of the axis there are two possibilities:
• two, three or four digital outputs of the module;
• an 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. This axis can be driven through
2 digital outputs or through the analog output.
