Part I - Hardware description
This section contains the hardware specifications of a Delem DAC-310 control.

1. Introduction
The DAC-310 is a universal programmable controller, designed to control machinery based
on incremental displacement such as the backgauge control of an industrial shear. For a better
understanding the backgauge will be referred to throughout this manual but any machine
section with a movement, measured by an incremental encoder, could be meant instead. The
DAC-310 is not confined to axis positioning but can program parameters, related to other
machine functions, as well.
It is possible to program several steps which can be combined to programs. The DAC-310 is
capable of controlling servo-loop systems, a one- or two-speed AC or DC drive system.

settings.

1. I/O assignments
The DAC-310 has several programmable features. These features can be enabled or disabled
in software and mapped to the I/O connectors of the DAC.
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:
Each choice opens a sub-menu with a matrix 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. 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
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 thes
signals become high, the output pin becomes high.

3. Parameter explanation
Parameter 00: Software version
Range : -
Unit : -
Default : -
Function
Version number of the current software.
Parameter 01: Type of drive
Range : 1 - 3
Unit : -
Default : 2
Function
The type of motor system that is to be controlled.
1 = 1-speed AC or DC drive
2 = 2-speed AC or DC drive
3 = Servo motor drive
Parameter 03: Scale factor
Range : 0.001 - 999.999
Unit : -
Default : 100
Function
Sets the scaling between encoder pulses and millimeters. The encoder gives an exact number
of pulses over a mm displacement. This value must be programmed here.
The value can be calculated by the formula:
F = NP / SPP
in which:
- NP = Number of encoder pulses per revolution of the spindle
- SPP = Spindle pitch in mm
Example:
- number of encoder pulses 100 ppr
- spindle pitch of 10 mm
results in F= 100 / 10 = 10

Delem
V0504, 2.8
Parameter 04: Decimal point position
Range : 0 - 3
Unit : -
Default : 1
Function
0 = 1 mm / 0.1 inch resolution
1 = 0.1 mm / 0.01 inch resolution
2 = 0.01 mm / 0.001 inch resolution
Parameter 05: Maximum backgauge position
Range : 0 - 9999
Unit : mm
Default : 9999
Function
Maximum backgauge position. This value is the physical limit. The axis will never be
controlled to a higher position than programmed here.
Parameter 06: Minimum backgauge position
Range : 0 - 9999
Unit : mm
Default : 0
Function
Minimum backgauge position. This value is the physical limit. The axis will never be
controlled to a lower position than programmed here.
Parameter 07: Indexing
Range : 0 - 1
Unit : -
Default : 1
Function
Each time the supply voltage is switched on, the reference position must be passed. This can
be done in two ways:
0 = no reference encoder used, the actual backgauge position will be memorized after power
down.
1 = automatic reference passing, the motor will be controlled after pushing the start button.

Delem
V0504, 2.9
Parameter 08: Reference position
Range : 0 - 9999
Unit : mm
Default : 100
Function
This position must appear on the display when the reference has passed. The reference
encoder must generate a pulse from low to high on the reference input.
Parameter 09: Enable reference correction input
Range : 0 - 1
Unit : -
Default : 0
Function
When set to 1, the ‘RFC’ input (ReFerence Correction) input is enabled. When this input is
active, the programmed position (Xm) will be copied to the actual position (Xp).
Parameter 10: Reference search direction
Range : 0 - 1
Unit : -
Default : 1
Function
Controls the direction of the reference search if Indexing (09) is programmed to 1.
0 = Downcounting direction.
1 = Upcounting direction.
Parameter 11: Spindle allowance
Range : 0 - 1
Unit : -
Default : 1
Function
0 = one-side positioning
1 = two-side positioning
Note: One-side positioning is also possible with a servo drive (drive type = 3)
In case of one-side positioning the positioning direction is from a larger to a smaller position.
Parameter 12: Enable retract

Delem
V0504, 2.10
Range : 0 - 1
Unit : -
Default : 0
Function
When set to 1, retraction is enabled.
Parameter 13: Auto retract
Range : 0 - 1
Unit : -
Default : 0
Function
When set to 1, retract is automatically started when ST goes low (start cutting).
Parameter 17: Positioning tolerance AC
Range : 0 - 9999
Unit : millimeters
Default : 0
Function
The backgauge position will position to the new programmed position if the difference
between the actual position and the new position is greater than this tolerance.
If the difference is smaller the backgauge will stay at its actual position.
This parameter is only available for drive types 1 and 2.
Parameter 18: Enable AC break
Range : 0 - 1
Unit : -
Default : 1
Function
Enable AC break output ‘BRK’. This can be used to control an AC motor with break.

Parameter 23: Overrun
Range : 0 - 9999
Unit : count pulses
Default : 50
Function
Overrun distance in case of one side positioning.
Overrun is always in the upcounting direction.
Note: This parameter must also be programmed if one-side positioning is used in combination
with a servo drive (type = 3).
Parameter 24: Overrun wait time

Delem
V0504, 2.12
Range : 0 - 9.9
Unit : seconds
Default : 1
Function
Wait time at overrun position before the backgauge starts positioning in the opposite
direction.
Parameter 25: DC-motor Slow speed
Range : 1 - 100
Unit : %
Default : 4
Function
This parameter must be programmed if 2-speed DC motor drives are used. It is progammed as
a percentage of maximum output deflection (10 V)
26: DC-motor fast speed
Range : 1 - 100
Unit : %
Default : 80
Function
This parameter must be programmed if 2-speed DC motor drives are used. It is progammed as
a percentage of maximum output deflection (10 V)
Parameter 27: Unipolar output
Range : 0 - 1
Unit : -
Default : 0
Function
When set to 1, the analog speed output will only output a positive signal. This can be used to
connect a frequency regulator for 1 or 2-speed AC control.
