WARRANTY TERMS

INITIAL WARRANTY

All products manufactured or marketed by FAGOR carry a 12-month warranty for the end user which could be controlled by the our service network by means of the warranty control system established by FAGOR for this purpose.

In order to prevent the possibility of having the time period from the time a product leaves our warehouse until the end user actually receives it run against this 12-month warranty, FAGOR has set up a warranty control system based on having the manufacturer or agent inform FAGOR of the destination, identification and on-machine installation date, by filling out the document accompanying each FAGOR product in the warranty envelope. This system, besides assuring a full year of warranty to the end user, enables our service network to know about FAGOR equipment coming from other countries into their area of responsibility.

The warranty starting date will be the one appearing as the installation date on the above mentioned document. FAGOR offers the manufacturer or agent 12 months to sell and install the product. This means that the warranty starting date may be up to one year after the product has left our warehouse so long as the warranty control sheet has been sent back to us. This translates into the extension of warranty period to two years since the product left our warehouse. If this sheet has not been sent to us, the warranty period ends 15 months from when the product left our warehouse.

This warranty covers all costs of material and labour involved in repairs at FAGOR carried out to correct malfunctions in the equipment. FAGOR undertakes to repair or replace their products within the period from the moment manufacture begins until 8 years after the date on which it disappears from the catalog.

FAGOR has exclusive competence in deciding whether the repair enters within the term defined as the warranty period.

EXCLUDING CLAUSES

Repairs will be carried out on our premises. Therefore, all expenses incurred as a result of trips made by technical personnel to carry out equipment repairs, despite these being within the above-mentioned period of warranty, are not covered by the warranty.

Said warranty will be applied whenever the equipment has been installed in accordance with instructions, has not be mistreated, has not been damaged by accident or by negligence and has not been tampered with by personnel not authorized by FAGOR. If, once servicing or repairs have been made, the cause of the malfunction cannot be attributed to said elements, the customer is obliged to cover the expenses incurred, in accordance with the tariffs in force.

Other warranties, implicit or explicit, are not covered and FAGOR AUTOMATION cannot be held responsible for other damages which may occur.

GENERAL CONCEPTS

1

The CNC may be programmed at the machine (from the front panel) and from a peripheral (computer). Memory available to the user for carrying out the part programs is 1 Mbyte.

The part programs and the values in the tables which the CNC has can be entered from the front panel, from a pc (DNC) or from a peripheral.

Entering programs and tables from the front panel.

Once the editing mode or desired table has been selected, the CNC allows you to enter data from the keyboard.

Entering programs and tables from a Computer (DNC) or peripheral device.

The CNC allows data to be exchanged with a computer or peripheral device, using the RS232C serial line.

If this is controlled from the CNC, it is necessary to preset the corresponding table or part program directory (utilities) you want to communicate with.

Depending on the type of communication required, the serial port machine parameter "PROTOCOL" should be set.

"PROTOCOL" = 0 If the communication is with a peripheral device.

"PROTOCOL" = 1 If the communication is via DNC.

Programming manual

1.1Part programs

The operating manual describes the different operating modes. Refer to that manual for further information.

Editing a part-program

To create a part-program, access the –Edit– mode.

The new part-program edited is stored in the CNC's RAM memory. A copy of the part-programs may be stored in the hard disk (KeyCF) at a PC connected through the serial line or in the USB disk.

To transmit a program to a PC through the serial, proceed as follows:

1.Execute the "WinDNC.exe" application program at the PC.

2.Activate DNC communications at the CNC.

3.Select the work directory at the CNC. It is selected from the –Utilities– mode, option Directory \Serial L \Change directory

In –Edit– mode, it is possible to modify part-programs residing in the CNC's RAM memory. To modify a program stored in the hard disk (KeyCF), in a PC or in the USB disk, it must be previously copied into RAM memory.

Executing and editing a part-program

Part-programs stored anywhere may be executed or simulated. Simulation is carried out in the –Simulation– mode, whereas the execution is done in the –Automatic– mode

When executing or simulating a part-program, bear in mind the following points:

•Only subroutines stored in the CNC's RAM memory can be executed. Therefore, to execute a subroutine stored in the hard disk (KeyCF), in a PC or in the USB disk, it must be first copied into the CNC's RAM memory.

•The GOTO and RPT instructions cannot be used in programs that are executed from a PC connected through the serial line.

•From a program in execution, it is possible to execute another program located in RAM memory, in the hard disk (KeyCF) or in a PC using the EXEC instruction.

The user customizing programs must be in RAM memory so the CNC can execute them.

–Utilities– operating mode.

The –Utilities– mode, lets display the part-program directory of all the devices, make copies, delete, rename and even set the protections for any of them.

Ethernet

When having the Ethernet option and if the CNC is configured as another node within the computer network, the following operations are possible from any PC of the network:

•Access the part-program directory of the hard disk (KeyCF).

•Edit, modify, delete, rename, etc. the programs stored on the hard disk.

•Copy programs from the hard disk to the PC and vice versa.

To configure the CNC as another node within the computer network, see the installation manual.

Programming manual

1.1.1Considerations regarding the Ethernet connection

When configuring the CNC as another node in the computer network, the programs stored in the hard disk (KeyCF) may be edited and modified from any PC.

Instructions for setting up a PC to access CNC directories

To set up the PC to access the CNC directories, we recommend to proceed as follows.

1.Open the "Windows Explorer"

2.On the "Tools" menu, select the "Connect to Network Drives" option.

3.Select the drive, for example "D".

4.Indicate the path. The path will be the CNC name followed by the name of the shared directory. For example: \\FAGORCNC\CNCHD

5.When selecting the option: "Connect again when initiating the session", the selected CNC will appear on each power-up as another path of the "Windows Explorer" without having to define it again.

Data format

This connection is established through Ethernet and, therefore, the CNC does not control the syntax of the programs while they are received or modified. However, whenever accessing the program directory of the Hard Disk (HD), the following verification takes place:

File name.

The file number must always have 6 digits and the extension PIM (for milling) or PIT (for lathe).

Examples:

001204.PIM 000100.PIM 123456.PIT 020150.PIT

If the file has been given the wrong name, for example: 1204.PIM or 100.PIT, the CNC will not change it, but it will display it with the comment "****************". The file name cannot be modified

at the CNC; it must be edited from the PC to correct the error.

File size.

If the file is empty (size = 0) the CNC will display it with the comment "********************".

The file can be edited or deleted either from the CNC or from the PC.

First line of the program.

The first line of the program must have the % character, the comment associated with the file (up to 20 characters) and between the two commas (,) the program attributes O (OEM), H (hidden), M (modifiable), X (executable).

Examples: %Comment ,MX,

% ,OMX,

If the first line does not exist, the CNC will display the program with an empty comment and with the modifiable (M) and executable (X) attributes.

When the format of the first line is wrong, the CNC does not modify it, but it displays it with the comment "****************". The file can be edited or deleted either from the CNC or from the

PC.

The format is incorrect when the comment has more than 20 characters, a comma (,) is missing to group the attributes or there is a strange character in the attributes.

1.3Communication protocol via DNC or peripheral device

This type of communication enables program-and-table transfer commands, plus the organization of CNC directories such as the computer directory, for copying/deleting programs, etc. to be done either from the CNC or the computer.

When you want to transfer files, it is necessary to follow this protocol:

•The "%" symbol will be used to start the file, followed by the program comment (optional), of up to 20 characters.

Then, and separated by a comma ",", comes the protection of each file, read, write, etc. These protections are optional and need not be programmed.

To end the file header, RT (RETURN ) or LF (LINE FEED) characters should be sent separated by a comma (",").

Example:

%Fagor Automation, MX, RT

•Following the header, the file blocks should be programmed. These will all be programmed according to the programming rules indicated in this manual. After each block, to separate it from the others, the RT (RETURN ) or LF (LINE FEED) characters should be used.

Example:	N20 G90 G01 X100 Y200 F2000 LF
	(RPT N10, N20) N3 LF

If communication is made with a peripheral device, you will need to send the ‘end of file’ command. This command is selected via the machine parameter for the serial port: "EOFCHR", and can be one of the following characters :

ESC	ESCAPE
EOT	END OF TRANSMISSION
SUB	SUBSTITUTE
EXT	END OF TRANSMISSION
