THE MEMORIES

A SRAM memory allows the programming and storing of products, tools and machine parameters. A lithium battery conserves the data during about 10 years.

Work memory (or buffer)

This memory is used for programming, modifying and executing products. It is a temporary memory whose contents are deleted whenever another product is called for.

The contents of this memory is conserved if the DNC power supply is cut, even if it has not been previously stored in the internal memory.

Internal memory

Sometimes called internal cassette, this fixed internal memory, of the static RAM type maintained by a lithium battery, contains the products, tools, axes positions, numbers concerning the production and machine parameters.

No programming or modification are done directly in this memory.

Flash memory

The DNC 600 is equipped with a Flash memory including the program and the cycle of the numerical control.

The machine cycle can be updated by means of the serial link RS232 (option).

PAGE 10 USER GUIDE DNC 600 PS

	Allows the storage and recall of data (products, tools, machine
	parameters) for the DNC 7000, DNC 70, and DNC 30 CNCs in a PC via
	the serial line.
	Up to 10 different CNCs can be selected.
	Ask for our "Product information" about CYBACK.
PC1200	PC1200 is a Windows program. This software allows to program on a PC
	in 2 and 3 dimensions the products to be realized on the numerical

THE USER INTERFACE

THE SCREEN

The screen displays the products, tools and machine parameters as well as all other useful information for programming and machine work.

The keys situated on the front of the DNC are used for selecting the screen pages and introducing data.

A cursor indicates where the user can intervene.

On all pages, when first displayed the cursor is located on the programmable field on which it was placed during the last intervention on that page.

The cursor can be moved to the previous or following field by pressing the or key.

Faster

Regardless of the cursor position on the page, pressing the

and the

keys simultaneously moves the cursor to the first programmable field of the page.

THE KEYBOARD

The keyboard is divided into six zones:

!Numerical keyboard

!Screen page selection keys

!Working mode zone

!The commands

!The cursor keys

!The manual mode keys

NUMERICAL KEYBOARD

The numerical keys as well as the and keys are used to introduce numbers or values into the different fields.

THE USER INTERFACE

THE SCREEN PAGE SELECTION KEYS

Main menu key

Gives access to the MAIN MENU page.

Product list key Double function key.

Pressing this key once displays the list of products in the DNC memory.

Pressing the key again displays the search for products by criteria page.

Product key

Triple function key.

Pressing this key once displays the angle length (L-alpha) values.

Pressing a second time displays the bending order with their respective legs.

Pressing a third time displays the bending values which are calculated as a function of the values introduced on the previous page.

Sequence key Triple function key.

Pressing the key once displays all the values and functions of the current sequence. Pressing a second time displays the first page of values in large characters.

Pressing a third time displays the second page of values and functions in large characters.

Correction key

This key displays the correction page which allows to make corrections to the current sequence, as well as to the entire product.

PAGE 14 USER GUIDE DNC 600 PS

THE WORKING MODES

Programming mode

Allows to introduce, modify and read data as well as to store, search for and transfer programs.

Manual mode

Authorizes axis movement and auxiliary

functions using the

keys.

Semi-automatic mode

Allows a machine cycle with the current sequence values without automatic sequence change.

This mode is used for adjustments when realizing the first product, as well as for products with only one bend.

The sequence change is made using the keys.

NB: The product counter Q does not function in this mode.

Automatic mode

Normal mode for product production.

The DNC automatically changes sequence after each bend.

Changing directly from "programming" mode automatically forces the first sequence of the program.

Changing from "programming " mode to "semiautomatic" mode and then to "automatic" mode, conserves the current sequence for execution.

This allows to take up again a product in production without having to make "empty" cycles.

THE USER INTERFACE

PAGE 15

THE COMMANDS

Delete key

Allows to delete a sequence or a program when the cursor is placed on the PRODUCT or N fields.

Only functions in programming mode.

Clear key

This key allows to delete data indicated by the cursor.

Caution: pressing this key twice, on most pages, deletes all the data on the page.

Search key

According to the cursor position allows:

-to search for a product

-to search for a sequence

-to search for a tool

-to search for a screen page

-to start a product feasibility calculation

-to transform L-alpha values into machine values

-to calculate the unfolded length of the sheet

-to execute a transfer

Only functions in programming mode.

Store / insert / teach key

Depending on the cursor position, allows to store the current program in the DNC internal memory, or create (insert) a new sequence in the middle of an existing program, or copy (teach) the value of an axis positioned manually in the current sequence.

This key is only valid in programming (memorization and insertion) mode and in manual (teach) mode.

type. Also allows to pass to the next page when a series of information occupies several pages.

Eg.: program sequence punch-die pages production pages parameter pages

In programming mode also allows to create an identical sequence (copy function) to the previous one as long as this is the last sequence of the program.

The incorporated LED indicates whether the sequence is the last of the program.

To indicate that an index is being taken the LED remains constantly alight, until the indexes are received. Indexes can only be taken

in or modes.

Stop key

Depending on the working mode chosen, stops the axes or auxiliary functions, or stops the calculation being executed.

When the DNC is in transfer mode (RS232) the STOP key allows to terminate the transfer.

PROGRAMMING

In this manual, it is being assumed that the DNC is configurated in such a way to be operational (i.e. the tools and machine parameters have already been programmed).

2 programming methods are accessible by the operator.

With unfolding calculation

!The L-alpha method.

The L-alpha method allows to enter a profile to be bended with the external dimensions and angles of each face. The DNC calculates the unfolded length.

After having programmed the bending order, the DNC will calculate the stop positions.

The faster method

!The direct programming.

The direct programming is the fastest method for an experimented operator, for the whole programming of the product is done on the same page. It enables to directly program the axes' positions, and it calculates the bending depth as a function of the introduced angle.

Before starting to program a product, make sure that the tools necessary to make the product exist in the DNC memory and write down the numbers of the punches and dies to be used.

To do this proceed as described below:

If you are already familiar with the tools present in the DNC, you may pass directly to chapter Programming on the L-alpha page, page 23).

!Note the number of the most appropriate punch.

If you don't find a punch which corresponds to your needs, you can create one.

In this case refer to chapter Tool programming, page 49.

It is possible, if more than four punches are programmed to see them by pressing the key.

Consulting the list of dies

Proceed in the same way as described above for punches; access from the main menu LIST OF DIES.

Pass to page 27 or page 40, depending on the chosen programming method.
