1. INTRODUCTION

The DAC-310 is a universal programmable controller, designed to

control machinery for incremental displacement of machine parts

such as the back gauge control of an industrial shear. For a better

understanding the back gauge will be referred to throughout this

manual but it is possible for any device with a movement,

measured by an incremental encoder.

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

a program. The DAC-310 is capable of controlling servo-loop

systems, a one- or two-speed AC or DC drive system.

3. OPERATING MODES

3.1. General

The DAC-310 has three operation modes:

• Manual mode

• Automatic mode

• Semi-automatic mode.

The DAC-310 can be programmed with 100 steps (0 - 99). You

can browse through the steps by pressing the + and - keys.

Manual mode is selected by moving to Step 0.

Automatic mode is selected when a program has been entered

and you move to the first step. Then you press the key for

automatic production.

Semi-automatic mode is simply selected by pressing the key for

semi-automatic.

Both keys (automatic and semi-automatic) also serve as start

buttons for each mode.

When the automatic or semi-automatic key is pressed the DAC-

310 will position the back gauge according to the programmed

parameters in the selected step.

The LED of the corresponding key (either automatic or semi-

automatic) will light up.

When the stop button (O) is pressed the DAC-310 will keep the

back gauge at its actual position. The LED of the stop button will

light up.

In some situations the "stop" is forced by the DAC-310 itself. In

that case the LED of the relevant start button extinguishes and

the LED of the stop button lights up.

In the following paragraphs the three operating modes are

described.

DAC-310 Delem

V0504, 8

When the start button is pressed the parameters Xm and Xp are

displayed, the programmed position and the actual position.

When the axis reached the programmed position, Xp is

highlighted and has the same value as Xm.

When the stop button is pressed the cursor moves back to the

selected parameter.

3.2. Manual mode

Manual mode is active in Step 0. It is indicated with

the hand symbol in the upper left corner.

In Manual Mode all parameters can be programmed.

When the automatic or semi-automatic key is pressed (start

function) in manual mode the back gauge moves to the

programmed position.

The stock counter (#) will be either incremented or decremented

at each manual cycle, depending on the setting (refer to chapter

4.3.8).

When the stock counter reaches zero in down counting mode the

DAC-310 stops. The # value is displayed at the top of the display.

The back gauge can be moved manually by pressing front keys.

To do so, the control must be stopped (the LED of the stop button

is lit). First move the cursor to the parameter Xp. The hand

symbol is now surrounded by two arrow symbols.

V0504, 9

Now the axis can be moved by pressing the manual movement

keys on the front panel. These keys are:

+ = slow speed in counting up direction

- = slow speed in counting down direction

X = high speed, must be pressed together with the + or - key.

3.3. Automatic mode

In Automatic Mode a program can be executed.

When the automatic key is pressed the back

gauge moves to the programmed position of the

first step.

The execution of different program steps is controlled with the

START input. When this input is switched from low to high, the

axis (back gauge) moves to the programmed position. When

switched from high to low, the next step is loaded.

DAC-310 Delem

V0504, 10

If the value for step repetition CY is higher than 1, only the value

of CY in the current step is decremented by 1 and no new step

will be loaded.

When the Automatic key is pressed to start a program, the control

automatically starts at Step 1. This happens whether or not the

parameter ST is programmed higher than zero. See chapter 4 for

more information about parameter ST.

3.4. Semi-automatic mode

The semi-automatic mode serves to execute a program step by

step.

The Semi-automatic Mode is started with its

own start key.

The execution cycle of a step runs similar to the one in automatic

mode. There are the following differences.

• The DAC-310 stops at the end of each step.

• A program is started at the step that is currently selected.

If the programmed value for CY is higher than 1 a number of

cycles equal to this value must have been executed before the

DAC-310 stops.

In semi-automatic mode you can choose to execute a program

step by step or execute a number of steps from the memory. This

depends on the value of the ST parameter. This will be explained

in detail in chapter 4.

4. PARAMETER PROGRAMMING

4.1. Introduction

The DAC-310 is a programmable back gauge controller.

The DAC-310 can also program parameters, related to other

machine functions.

One such set of parameters is referred to as a "step".

Several steps can be combined to build a program. During the

execution of the program the steps within the program are

executed one after another in an automatic cycle. The control

switches to the next step when a Start/Enable signal is received.

4.2. Identification of a step

A step is identified by a number in the range 0-99. This means

that up to 100 steps can be programmed and stored into memory.

Step 0 is an exception. This step is the manual mode of the

control and is never part of any program.

The number of the selected step is displayed in the upper left

corner of the display.

The keys + and - are used to browse through the available steps.

Holding the keys + or - will speed up the effect.

4.3. Programmable Parameters

4.3.1. General

A parameter can be programmed upon selection. The selected

parameter is indicated by a symbol. Selecting a parameter is

done by pressing the arrow keys. The actual value of the selected

parameter is displayed.

Each programmed parameter is checked against its minimum and

maximum value. If a programmed value is invalid the value will be

limited at its minimum or maximum value.

The function Xp is not a programmable parameter. If Xp is

selected the actual position of the back gauge is displayed.

The parameters are:

- Xp = actual position of the back gauge

- Xm = programmed position of the back gauge

- # = Stock counter: counting of products

- ST = the number of steps

- M = entry point for programming constants

4.3.2. Actual position readout Xp

If Xp is selected the actual back gauge position is displayed.

If the reference has not passed yet only a dashed line is

displayed.

When a programmed step is shown, Xp cannot be selected as a

parameter, it can only be read from the central part of the display.

You can only select Xp when you are in manual mode (step 0).

Then you can move the axis with the +/- keys.

4.3.3. Back gauge position Xm

Xm is the intended position for the axis. Xm must be programmed

to the required value.

Delem

V0504, 13

Everytime a step is executed, the axis moves to the programmed

position Xm. The actual position is shown by Xp. When the axis

has reached position, Xp has the same value as Xm. Xp is then

highlighted on the display.

When the cursor is at Xm a value is displayed with a format

depending on machine settings.

Either millimetres or inches is possible.

Note:

The back gauge position can also be programmed negative. In

that case, it is considered as a chaining value.

4.3.4. COR(rection)

Correction on the programmed back gauge position.

The value to be programmed at COR appears in the same

resolution as Xm.

Default: 0

Note: the presence of this parameter depends on machine

settings

4.3.5. Retract distance DX

In some cases it may be necessary to clear (retract) the material

from the back gauge. This may occur at the moment when the

mechanical action begins. The retract distance is a programmable

displacement of the motor axis in the up counting direction.

The value at DX appears in the same resolution as Xm.

Default: 0

Note: the presence of this parameter depends on machine

settings

DAC-310 Delem

V0504, 14

4.3.6. Function Outputs F

There are two function (on/off) outputs: F1 and F2.

The value of these two outputs can be programmed as one

parameter.

There are four combinations:

Value F2 F1

00 off off

01 off on

10 on off

11 on on

Default: 00 (both off)

A combination can be programmed with function F.

The digital outputs will be set to the programmed value when the

start-enable input becomes high while the DAC has been started.

The outputs stay at the actual value during the program step and

will be reset when the DAC is stopped.

Note: the presence of this parameter depends on machine

settings

4.3.7. Repetition CY

Step repetition: the number of times a step is repeated before the

next step is executed.

Range : 0 - 9999

Default: 1

Note 1:

The value 0 means that the step must be skipped.

Note 2:

This parameter has no meaning in Manual mode and is equal to

Note 3:

The presence of this parameter depends on machine settings
