SAFETY AND MAINTENANCE INSTRUCTIONS
!The operator must be trained for working with the
machine on which the numerical control is installed.
!Improper use of the numerical control can cause
heavy damage on equipment and/or injuries to
people.
!Modification of machine parameters can cause
important material damage or lead to irregular
product quality.
!The rear panel may only be removed by a qualified
technician (danger of electrocution).
!Do not expose the numerical control to excessive
humidity so as to avoid any risk of electrocution and
any deterioration of the equipment.
!Make sure the numerical control is disconnected
from the mains power before carrying out any
cleaning. Do not use liquids based on alcohol or
ammoniac.
!In case of malfunction of the numerical control, call a
technician.
!Do not expose the numerical control to direct sun
rays or any other heat source.

ABOUT THIS MANUAL
This manual is designed to help the user to familiarize with the numerical
control DNC 60 and to use it with a maximum of efficiency.
To reach a maximum of comfort and productivity of the numerical control, it
is recommended to read attentively the whole manual.
A table of contents and a well organized index enable you to find rapidly the
searched subject.
How to get rapidly acquinted with the numerical control ?
Follow the rabbit. It will pass through the important stages and will guide you
in the programming of an example product.

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 60 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).

DESCRIPTION OF THE DNC 60 PS PAGE 11
ACCESSORIES
CYBACK Software for storage in PC.
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.
PC900 / PC1200 PC900 is a DOS program, PC1200 a Windows program.
This software allows to program on a PC in 2 and 3 dimensions the
products to be realized on the numerical control.
This software executes the simulation and graphic display of the bending
order taking into account the characteristics of the machine, the tools and
the material.
An option (LINK7000, see below) allows to transfer products to the
DNC 7000, DNC 70, DNC 50 and DNC 60.
LINK7000 Option of the software PC900 / PC1200 to transfer products to the
DNC 7000, DNC 70, DNC 50 or DNC 60 by the serial line.
