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 under takes 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 catalogue.
It is entirely up to FAGOR to determine whether the repair is or not under warranty.
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 authorised 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.
CNC 8065

Probing (·T· model)
WARRANTY ON REPAIRS
In a similar way to the initial warranty, FAGOR offers a warranty on standard repairs according to the
following conditions:
PERIOD 12 months.
CONCEPT Covers parts and labor for repairs (or replacements) at the
network's own facilities.
EXCLUDING CLAUSES The same as those applied regarding the chapter on initial
warranty. If the repair is carried out within the warranty period, the
warranty extension has no effect.
When the customer does not choose the standard repair and just the faulty material has been replaced,
the warranty will cover just the replaced parts or components within 12 months.
For sold parts the warranty is 12 moths length.

CNC MAINTENANCE
CLEANING
The accumulated dirt inside the unit may act as a screen preventing the proper dissipation of the heat
generated by the internal circuitry which could result in a harmful overheating of the unit and, consequently,
possible malfunctions. Accumulated dirt can sometimes act as an electrical conductor and short-circuit the
internal circuitry, especially under high humidity conditions.
To clean the operator panel and the monitor, a smooth cloth should be used which has been dipped into
de-ionized water and /or non abrasive dish-washer soap (liquid, never powder) or 75º alcohol. Do not use
highly compressed air to clean the unit because it could generate electrostatic discharges.
The plastics used on the front panel are resistant to grease and mineral oils, bases and bleach, dissolved
detergents and alcohol. Avoid the action of solvents such as chlorine hydrocarbons, venzole, esters and
ether which can damage the plastics used to make the unit’s front panel.
PRECAUTIONS BEFORE CLEANING THE UNIT
Fagor Automation shall not be held responsible for any material or physical damage derived from the
violation of these basic safety requirements.
• Do not handle the connectors with the unit connected to AC power. Before handling these connectors
(I/O, feedback, etc.), make sure that the unit is not connected to main AC power.
• Do not get into the inside of the unit. Only personnel authorized by Fagor Automation may manipulate
the inside of this unit.
• If the CNC does not turn on when actuating the start-up switch, verify the connections.

PREVIOUS NOTIONS ABOUT THE PROBE.
Number of probes in the system and active probe.
The CNC may have configured two probes, it will usually be a tabletop probe to calibrate tools
and a touch probe to measure the part.
Before any probing moves, select the probe to be used. See "1.1 Activate the probe." on
page 22.
Probe operation.
Both probes operate by levels, not by flanks.
Probing.

With function G100, it is possible to program movements that will end when the CNC receives
the probe signal (when the probe makes contact). When done probing, the CNC updates
the real coordinates.
With function G103, it is possible to program movements that will end when the CNC stops
receiving the probe signal (when the probe no longer makes contact). When done probing,
the CNC updates the real coordinates.
The G104 function prevents a G100 or G103 probe movement from finishing with the probe
signal The CNC updates the coordinates with the probe signal, but without interrupting the
movement which continues until the probe reaches the programmed position.
Programming the canned cycles.
The probing canned cycles may be edited in ISO code or with using the cycle editor. These
cycles may be defined anywhere in the program, that is, in the main program as well as in
a subroutine. ISO coded cycles can also be executed in MDI.
Probe parameter setting.
The machine manufacturer must have properly set the following machine parameters.
• General machine parameters.
PROBE PROBEDATA PROBETYPE1 PROBETYPE2
PRBDI1 PRBDI2 PRBPULSE1 PRBPULSE2
• General machine parameters per channel.

1.1 Activate the probe.
The CNC can have configured two probes. Before any probing move, the CNC must know
which is the active probe, or, which is the same, which of the two probes it must attend to.
It is selected via part-program or MDI using the instruction #SELECT PROBE.
If a probing move is executed without activating the probe, it will not send any signal to the CNC when
it makes contact. This can cause the probe to break because the probing move will not be stopped.

Activate the probe.
PREVIOUS NOTIONS ABOUT THE PROBE.
Programming.
When programming this instruction, you must define which probe is active and whether it's
active high or low.
Programming format.
The programming format is the following; the list of arguments appears between curly
brackets and the optional ones between angle brackets.
#SELECT PROBE [<{probe}><, {pulse}>]
{probe} Optional. Number of probe to activate.
If not programmed, the CNC uses the active probe.
{pulse} Optional. Logic level to activate probe. The CNC uses the high level with
"POS" and the low level with "NEG".
If not programmed, the CNC uses the default probe activation level.
Although both parameters are optional, at least one of them must be programmed.
#SELECT PROBE [1]
#SELECT PROBE [NEG]
#SELECT PROBE [2, POS]
#SELECT PROBE [1, NEG]
Probe number. Which is probe 1 and which probe 2?
CNC 8065
(REF: 1309)
The names of the probes are set in the order they have been defined in the machine
parameters. The CNC assumes as first probe the one connected to the input indicated in
machine parameter PRBDI1 and as second probe the one connected to the input indicated
in machine parameter PRBDI2.
Logic level to activate probe; high (5 V / 24 V) or low (0 V).
Changing the default activation level reverses the operation of functions G100 and G103.
When changing the probe logic activation level, G100 makes a movement until the probe
stops making contact and G103 makes a movement until the probe makes contact. Since
probing canned cycles use functions G100 and G103, changing the logic activation level also
changes the operation of the canned cycles accordingly.
The logic activation level indicates whether the probe operations are active high (24V or 5
V) or active low (0V) of the signal provided by the probe. Programming the logic activation
level is optional because each probe has been assigned one by default.
The logic activation level of each probe by default is set in the machine parameters
(parameters PRBPULSE1 for probe ·1· and PRBPULSE2 for probe ·2·) and it depends on
the connection between the probe and the CNC.
Properties of the instruction and influence of reset, turning the
CNC off and of the M30 function.
The instruction #SELECT PROBE is modal. The probe and the selected logic activation level
stays active after an M02 or M30 and after an error or a reset. On power-up and after
validating the machine parameters, the CNC activates probe ·1· and initializes the logic
activation level of both probes with the values set in the machine parameters.

Knowing which is the active probe.
The CNC offers the following variable to know which is the active probe. The variable can
only be read via part-program, MDI, PLC and interface.

1.2 Geometric configuration of axes and work planes.
The CNC admits two types of geometric configurations; "Trihedron" type and "Plane" type
axis configuration.
Trihedron Plane
Configuration of "Trihedron" type axes.
In this configuration, there are three axes forming a Cartesian XYZ type trihedron like on a
milling machine. There may be more axes besides those forming the trihedron.
PREVIOUS NOTIONS ABOUT THE PROBE.
Geometric configuration of axes and work planes.
With this configuration, the planes behave in the same way as on a milling machine except
that the usual work plane will be G18 (if it has been configured like that).
All the movements of these cycles are executed on the X Y Z axes; the work plane must be
formed by 2 of these axes (XY, XZ, YZ, YX, ZX, ZY). The other axis, that must be
perpendicular to that plane must be selected as axis perpendicular to the work plane.
Configuration of "plane" type axes.
In this configuration, there are two axes forming the usual work plane. There may be more
axes, but they cannot be part of the trihedron; there must be auxiliary, rotary, etc.
With this configuration, the work plane is always G18 and will be formed by the first two axes
defined in the channel. If the X (first) and Z (second) axes have been defined, the work plane
will be the ZX (Z as abscissa and X as ordinate).
The probing movements can only be executed in the work plane. The CNC ignores the
programmed variables that are related to the axis perpendicular to the work plane.
Configuration of "plane" type axes. Plane selection.
The work plane is always G18; machine parameter IPLANE is not applied and it is not
possible to change planes via part-program. The following functions have these effects:
G17 It does not change planes and shows a warning about it.
G18 It has no effect.
G19 It does not change planes and shows a warning about it.
