It is possible that CNC can execute more functions than those described in itsassociated documentation; however, Fagor Automation does not guarantee thevalidity of those applications. Therefore, except under the express permissionfrom Fagor Automation, any CNC application that is not described in thedocumentation must be considered as "impossible". In any case, FagorAutomation shall not be held responsible for any personal injuries or physicaldamage caused or suffered by the CNC if it is used in any way other than asexplained in the related documentation.
The content of this manual and its validity for the product described here has beenverified. Even so, involuntary errors are possible, thus no absolute match isguaranteed. Anyway, the contents of the manual is periodically checked makingand including the necessary corrections in a future edition. We appreciate yoursuggestions for improvement.
The examples described in this manual are for learning purposes. Before usingthem in industrial applications, they must be properly adapted making sure thatthe safety regulations are fully met.
MACHINE SAFETY
It is up to the machine manufacturer to make sure that the safety of the machineis enabled in order to prevent personal injury and damage to the CNC or to theproducts connected to it. On start-up and while validating CNC parameters, itchecks the status of the following safety elements. If any of them is disabled, theCNC shows a warning message.
Feedback alarm for analog axes. Software limits for analog and sercos linear axes. Following error monitoring for analog and sercos axes (except the spindle)
both at the CNC and at the drives. Tendency test on analog axes.
FAGOR AUTOMATION shall not be held responsible for any personal injuries orphysical damage caused or suffered by the CNC resulting from any of the safetyelements being disabled.
HARDWARE EXPANSIONS
FAGOR AUTOMATION shall not be held responsible for any personal injuries orphysical damage caused or suffered by the CNC resulting from any hardwaremanipulation by personnel unauthorized by Fagor Automation.
If the CNC hardware is modified by personnel unauthorized by Fagor Automation,it will no longer be under warranty.
COMPUTER VIRUSES
FAGOR AUTOMATION guarantees that the software installed contains nocomputer viruses. It is up to the user to keep the unit virus free in order toguarantee its proper operation.
Computer viruses at the CNC may cause it to malfunction. An antivirus softwareis highly recommended if the CNC is connected directly to another PC, it is partof a computer network or floppy disks or other computer media is used to transmitdata.
FAGOR AUTOMATION shall not be held responsible for any personal injuries orphysical damage caused or suffered by the CNC due a computer virus in thesystem.
If a computer virus is found in the system, the unit will no longer be under warranty.
