MACHINE SAFETY
It is up to the machine manufacturer to make sure that the safety of the machine
is enabled in order to prevent personal injury and damage to the CNC or to the
products connected to it. On start-up and while validating CNC parameters, it
checks the status of the following safety elements. If any of them is disabled, the
CNC 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 or
physical damage caused or suffered by the CNC resulting from any of the safety
elements being disabled.
HARDWARE EXPANSIONS
FAGOR AUTOMATION shall not be held responsible for any personal injuries or
physical damage caused or suffered by the CNC resulting from any hardware
manipulation 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 no
computer viruses. It is up to the user to keep the unit virus free in order to
guarantee its proper operation.
Computer viruses at the CNC may cause it to malfunction. An antivirus software
is highly recommended if the CNC is connected directly to another PC, it is part
of a computer network or floppy disks or other computer media is used to transmit
data.
FAGOR AUTOMATION shall not be held responsible for any personal injuries or
physical damage caused or suffered by the CNC due a computer virus in the
system.
If a computer virus is found in the system, the unit will no longer be under warranty.

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 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.

Programming manual
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.

A subroutine is a set of blocks that, once properly identified, may be called upon several times
from another subroutine or from the program. Subroutines are normally used for defining a
bunch of operations or movements that are repeated several times throughout the program.

Types of subroutines.
Programming manual
1.
Program structure.
CREATING A PROGRAM.
The CNC has two types of subroutines, namely local and global. There is also a third type
available, OEM subroutines, that are a special case of a global subroutine defined by the
OEM.
Global subroutines.
The global subroutine is stored in CNC memory as an independent program. This subroutine
may be called upon from any program or subroutine being executed.
Local subroutines.
The local subroutine is defined as part of a program. This subroutine may only be called upon
from the program where it has been defined.
A program can have several local subroutines; but they all must be defined before the body
of the program. A local subroutine can call a second local subroutine with the condition that
the calling subroutine be defined after the one being called.

1.3 Program block structure.
The blocks comprising the subroutines or the program body may be defined by commands
in ISO code or in high-level language. Each block must be written in either language but not
mixed; a program may combine blocks written in both languages. Empty blocks (empty lines)
are also allowed.
In either language, it is also possible to use any type of arithmetic, relational or logic
expression.
Programming in ISO code.
It is especially designed to control the movement of the axes because it provides movement
data and conditions as well as feedrate and speed. Some of the available commands are:
• Preparatory functions for movement establishing the geometry and work conditions such
as linear and circular interpolations, threading, canned cycles, etc.
• Functions to control cutting conditions such as feedrate of the axes, spindle speed and
accelerations.
• Functions to control the tools.
• Additional functions containing technological instructions.
• Definition of position values.
High-level language programming.
This language provides the user with a set of control commands with a terminology similar
to the one used by other languages, such as $IF, $GOTO, #MSG, #HSC, etc. Some of the
available commands are:
• Programming instructions.
• Flow controlling instructions to make loops and jumps within the program.
• To define and call upon subroutines with local parameters where a local variable is the
one only known to the subroutine where it has been defined.
It is also possible to use any type of arithmetic, relational or logic expression.

Likewise, the numerical format may be replaced by a parameter, variable or arithmetic
expression whose result is a number.
Programming allows blank spaces between letters, numbers and a sign as well as not using
the sign with positive values.
Block structure.
A block may have the following functions, but needs not contain all of them. The data has
no set order, it may be programmed anywhere in the block. The only exception being the
block-skip condition and the block identification which must always be programmed at the
beginning.
/N—G—G—X..C—F—S—T—D—M—H—NR—
·/· Block skip condition.
If the block-skip mark is active, the CNC will skip the blocks having this character (not
executing them) and will go on to the next block.
The CNC reads several blocks ahead of the one in execution, in order to calculate in advance
the path to travel. The block-skip condition is examined at the time when the block is read.
·N· Block identification.
The block identification must be programmed when the block is used as the destination of
references or jumps. In this case, it is recommended to program it alone in the block. It may
be represented in two ways:
• The letter "N" followed by the block number (0-4294967295) and the ":" character (only
when the label is used as the destination of a block jump); they need not follow a particular
order or be consecutive.
If the label is not a jump target and is programmed without ":", it may go in any position
of the block, not necessarily at the beginning.
• "[<name>]" type labels, where <name> may be up to 14 characters long and may consist
of uppercase and lowercase characters as well as numbers (no blank spaces are
allowed).
Both types of data may be programmed in the same block.

Depending on the units, the programming format will be:
• In millimeters, format ±5.4 (5 integers and 4 decimals).
• In inches, format ±4.5 (4 integers and 5 decimals).
·F· Axis feedrate.
The feedrate is represented by the letter "F" followed by the desired feedrate value.
Programming manual
·S· Spindle speed
This function sets the spindle speed.
The spindle name is defined by 1 or 2 characters. The first character is the letter S and the
second character is optional, it must be a numerical suffix between 1 and 9. This way, the
name of the spindles may be within the range S, S1 ... S9.
The feedrate is represented by the axis letter followed by the target position for the axis. For
spindles like S1, S2, etc. the "=" sign must be included between the axis name and the speed.
S1000
S1=334
·T· Tool number.
This function selects the tool to be used to carry out the programmed machining operation.
The tool is represented by the letter "T" followed by the tool number (0-4294967295).
·D· Tool offset number.
This function selects the tool offset. The tool offset is represented by the letter "D" followed
by the tool offset number. The number of offsets available for each tool is defined in the tool
table.
·M H· Auxiliary functions.

Program block structure.
CREATING A PROGRAM.
With the auxiliary functions, it is possible to control machine elements such as spindle turning
direction, coolant, etc. These functions are represented by the letters "M" or "H" followed by
the function number (0-65535)
·NR· Number of block repetitions.
It indicates the number of times the block will be executed. It can only be programmed in
blocks containing a movement.
If the block is under the influence of a modal canned cycle, the latter will be repeated as many
times as the block repetition has been programmed. When programming NR0, the
movements will be executed, but the modal canned cycle is not executed at the end of each
one.

(REF. 1309)
The high-level commands comprise the instructions and flow control instructions.
• Instructions are programmed preceded by the "#" sign and they can only be programmed
one per block. They are used to carry out various functions.
• Flow control instructions are programmed preceded by the "$" sign and can only be
programmed one per block. They are used to make loops and program jumps.
Assigning values to parameters and variables can also be considered as high-level
commands.

The axis name is defined by 1 or 2 characters. The first character must be one of the letters
X - Y - Z - U - V - W - A - B - C. The second character is optional and will be a numerical
suffix between 1 and 9. This way, the name of the spindles may be within the range X,
X1…X9,...C, C1…C9.
The movements are represented by the axis letter followed by the target position for the axis.
For axes like X1, Y2, etc. the "=" sign must be included between the axis name and the
coordinate.

Programming using wild cards.
The axes can also be programmed using wild cards. The wild cards may be used to program
and refer to the axes of the channel using their position in it, including the empty spaces.
The wild card is represented with the "?" character followed by the position number of the
axis, ?1 for the first axis, ?2 for the second one, and so forth. If the position of an empty space
is programmed, the CNC will display an error message.
In a channel with the following distribution of axes,
the wild cards refer to the following axes.
• The ?1 wild card corresponds to the Y axis.
• The ?2 wild card corresponds to the X axis.
• The ?3 wild card issues an error, there is no
axis in that position.
• The ?4 wild card corresponds to the Z axis.

1.10 Arithmetic parameters.
Arithmetic parameters.
Programming manual
Arithmetic parameters are general purpose variables that the user may utilize to create
his/her own programs. The CNC has global, local and common arithmetic parameters. The
range of available parameters of each type is defined in the machine parameters.
Arithmetic parameters are programmed with the "P" code followed by the parameter number.
The has some tables for consulting the value of these parameters; refer to the operating
manual to learn how to handle these tables.
The user may use the arithmetic parameters when editing its own programs. During
execution, the CNC will replace these parameters with the values assigned to them at the
time.

CREATING A PROGRAM.
Local arithmetic parameters.
Local parameters may only be accessed from the program or subroutine where they have
been programmed. There are seven groups of local parameters in each channel.
The maximum range of local parameters is P0 to P99, the typical range being P0 to P25.
When the parameters are used in the block calling a subroutine may also be referred to by
the letters A-Z (except Ñ and Ç) so "A" is the same as P0 and "Z" the same as P25.
Global arithmetic parameters.
Global parameters may be accessed from any program and subroutine called upon from the
program. The value of these parameters is shared by the program and the subroutines. There
is a group of global parameters in each channel.
The maximum range of global parameters is P100 to P9999, the typical range being P100
to P299.
Common arithmetic parameters.
The common parameters may be accessed from any channel. The value of these parameters
is shared by all the channels. Reading and writing these parameters interrupts block
preparation.
The maximum range of common parameters is P10000 to P19999, the typical range being
P10000 to P10999.

Programming the arithmetic parameters.
In blocks programmed in ISO code, it is possible to define the values of all the fields "N", "G",
"F", "S", "T", "D", "M", "H", "NR" and axis coordinates using parameters. Using indirect
addressing, it is also possible to define the number of a parameter with another parameter;
"P[P1]", "P[P2+3]".
In blocks having statements, the values of any expression may be defined with parameters.

1.12 Arithmetic and logic expressions.
An expression is any valid combination of operators, constants, parameters and variables.
Expressions may be used to program the numerical portion of any function, statement, etc.
The priorities of the operators and the way they can be associated determine how these
expressions are calculated:
Priority from highest to lowest They are associated

+ (suma, OR lógico), - (resta) from left to right.
Relational operators from left to right.
& (AND),^ (XOR) from left to right.
| (OR) from left to right.
Brackets should be used in order to clarify the order in which the expression is to be
evaluated. Using redundant or additional brackets will neither cause errors nor slow down
the execution.

MACHINE OVERVIEW
2.1 Axis nomenclature
With this CNC, the manufacturer may select up to 28 axes (that must be properly defined
as linear, rotary, etc. by setting machine parameters), without no limitation as how to program
them and they may all be interpolated at the same time.
The DIN 66217 standard denomination for the axes is:
X-Y-Z Main axes of the machine. The X-Y axes form the main work plane whereas the
Z axis is parallel to the main axis of the machine and perpendicular to the XY
plane.
U-V-W Auxiliary axes, parallel to X-Y-Z respectively.
A-B-C Rotary axes, on X-Y-Z respectively.
However, the machine manufacturer may call the axes differently.

As an option, the name of the axes may be followed by a number between 1 and 9 (X1, X3,
Y5, A8...).

2.2 Coordinate system
Since one of the CNC's purposes is to control the movement and positioning of the axes,
a coordinate system is required that permits defining the position of the various target
(destination) points in the plane (2D) or in space (3D).
The main coordinate system is formed by the X-Y-Z axes. These axes are perpendicular to
each other and they meet at the origin point used as reference for the various points.
2.

A machine may use the following reference systems.
• Machine reference system.
It is the coordinate system of the machine and it is set by the manufacturer of the machine.
• Fixture reference system.
It establishes a coordinate system associated with the fixtures being used. It is activated
by program and may be set by the operator in any position of the machine.
When the machine has several fixtures, each one may have its own reference system
associated with it.
• Part reference system (datum point).
It establishes a coordinate system associated with the part being machined. It is activated
by program and may be set by the operator anywhere on the part.

Part zero
It is the origin point of the reference system of the part (workpiece). Its position is set by the
operator using the "zero offset" and is referred:
• To the fixture offset, if the fixture reference system is active. When changing the fixture
reference system, the CNC updates the part zero position by referring to the new fixture
zero point.
• To the machine zero point (home), if the fixture reference system is NOT active. When
activating the fixture reference system, the CNC updates the part zero position by
referring it to the fixture zero point.
The "zero offset" may be set from the program or from the CNC front panel as described in

2.4 Home search
2.4.1 Definition of "Home search"
Home search
MACHINE OVERVIEW
Programming manual
It is the operation used to synchronize the system. This operation must be carried out when
the CNC loses the position of the origin point (e.g. by turning the machine off).
In order to perform the "Home search", the machine manufacturer has set particular points
of the machine; the machine zero and the machine reference point.
• Machine zero (home).
It is the origin point of the machine reference system.
• Machine reference point.
It is the physical point where the system is synchronized (except when the machine uses
distance-coded reference marks or absolute feedback). It may be located anywhere
I
0
on the machine.
When "searching home", the axes move to the machine reference point and the CNC
assumes the coordinate values assigned to that point by the machine manufacturer, referred
to machine zero. When using I
distance-coded reference marks or absolute feedback, the
0
axes will only move the distance necessary to verify their position.

therefore, the coordinates are displayed in the active reference system.
On the other hand, if "Home search" is carried out one axis at a time in JOG mode (not in MDI), the
active offsets are canceled and the coordinates being displayed are referred to machine zero.

2.4.2 "Home search" programming
When programming a "Home search", the axes are homed sequentially in the order set by
the operator. All the axes need not be included in the "Home search", only those being
homed.
The "Home search" is programmed using the G74 function followed by the axes to be homed
and the number indicating their homing order. If the same order number is assigned to several
axes, those axes start homing at the same time and the CNC waits for all of them to end before
homing the next one.
When having numbered axes, they may be defined together with the other ones by assigning
them the order number as follows.
2.
Home search
MACHINE OVERVIEW
Spindle home search
The spindle home search is always carried out together with the first axis regardless of the
order in which it has been defined.
Home search and loop status.
Axes usually work in closed loop, although rotary axes can also work in open loop so they
can be controlled as if they were spindles.
The home search is carried out with the axes and spindles controlled in position; i.e. in closed
position loop. The CNC will close the position loop automatically on all axes and spindles
for which a home search has been programmed using function G74.
Using an associated subroutine
If the machine manufacturer has associated a home-search subroutine to the G74 function,
this function may be programmed alone in the block and the CNC will automatically execute
the associated subroutine [G.M.P. "REFPSUB (G74)"].
When using a subroutine, the "Home search" is carried out exactly as described earlier.

3.2.1 Rotary axes.
The CNC admits different ways to configure a rotary axis depending on how it is going to
move. Hence, the CNC can have rotary axes with travel limits, for example between 0º and
180º (linearlike rotary axis); axes that always move in the same direction (unidirectional
rotary axis); axes that choose the shortest path (positioning-only rotary axis).
All rotary axes must be programmed in degrees; therefore, they will not be affected by the
mm-inch conversion. The number of revolutions the axis will turn when programming a
distance greater than the module depends on the type of axis. The limits to display the
position values (coordinates) also depend on the type of axis.
Linearlike rotary axis.
The axis behaves like a linear axis, but it is programmed in degrees. The CNC displays the
position values between the travel limits.
Normal rotary axis.
This type of rotary axis can turn in both directions. The CNC displays the position values
between the limits of the module.
G90 movements. G91 movements.
The sign of the position value indicates the
moving direction; the absolute position value
indicates the target position.
Even if the programmed distance is greater than
the module, the axis never turns more than one
revolution.
Normal incremental movement. The sign of the
position value indicates the moving direction; the
absolute position value indicates the position
increment.
If the programmed distance is greater than the
module, the axis turns more than one revolution.

The axis moves in the preset direction up to the
programmed position.
Even if the programmed distance is greater than
the module, the axis never turns more than one

Programming manual
Coordinates are programmed according to a Cartesian coordinate system. This system
consists of two axes in the plane and three or more in space.
Definition of position values
The position of a point in this system is given by its coordinates in the different axes. The
coordinates are programmed in absolute or incremental coordinates and in millimeters or
inches.
Standard axes (X...C)
The coordinates are programmed with the axis name followed by the coordinate value.

3.4.2 Polar coordinates
When having circular elements or angular dimensions, polar coordinates may be more
convenient to express the coordinates of the various points in the plane.
This type of coordinates requires a reference point referred to as "polar origin" that will be
the origin of the polar coordinate system.
Definition of position values
The position of the various points is given by defining the radius "R" and the angle "Q" as
follows:
Radius It will be the distance between the polar origin and the point.
Angle It will be the one formed by the abscissa axis and the line joining the polar
3.
origin with the point.
R Radius
Q Angle
OP Polar origin
The radius may be given in mm or in inches whereas the angle is given in degrees.
Both values may be given in either absolute (G90) or incremental (G91) coordinates.
• When working in G90, the "R" and "Q" values will be absolute. The value assigned to
the radius must always be positive or zero.
• When working in G91, the "R" and "Q" values will be incremental. Although negative "R"
values may be programmed, when programming in incremental coordinates, the
resulting value assigned to the radius must always be positive or zero.
When programming a "Q" value greater than 360º, the module will be assumed after dividing
it by 360. Thus, Q420 is the same as Q60 and Q-420 is the same as Q-60.
Polar origin preset
The "polar origin" may be selected from the program using function G30. If not selected, it
assumes as "polar origin" the origin of the active reference system (part zero). See chapter
"5 Origin selection".
Coordinate programming
COORDINATE SYSTEM
The selected "polar origin" is modified in the following instances:
• When changing the work plane, the CNC assumes the part zero as the new "polar origin".
• On power-up, after an M02 or M30 and after an EMERGENCY or a RESET, the CNC
assumes the part zero as the new polar origin.

WORK PLANES.
The work planes determine which axes define the work plane/trihedron and which axis
corresponds to the longitudinal axis of the tool. Plane selection is required to execute
operations like:
• Circular and helical interpolations.
• Corner chamfering and rounding.
• Tangential entries and exits.
• Machining canned cycles.
• Tool radius and length compensation.
These operations, except tool length compensation, can only be executed in the active work
plane. Tool length compensation, on the other hand, can only be applied on the longitudinal
axis.

4.1 About work planes on lathe and mill models.
The operation of the work planes depends on the geometric configuration of the axes. At a
mill model, the geometric configuration of the axes is always of the "trihedron" type whereas
at a lathe model, the geometric configuration of the axes may be either a "trihedron" type
or a "plane" type (parameter GEOCONFIG).

About work planes on lathe and mill models.
This configuration has three axes forming a trihedron Cartesian XYZ type . There may be
more axes, besides those forming the trihedron; that may be part of the thihedron or be
auxiliary axes, rotary axes, etc.
The order of the axes in the channel sets the main work planes, those selected with functions
G17, G18 and G19. Function G20 may be used to form any work plane with the first three
axes of the channel. The work plane by default is set by the manufacturer (parameter
IPLANE), the usual plane being G17 at a mill model and G18 at a lathe model.
The CNC displays the ·G· functions associated with the work planes.
Configuration of "plane" type axes (lathe model).
This configuration has two axes forming the usual work plane on a lathe. 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, the second axis as abscissa and the first axis as ordinate. The ·G·
functions associated with the work planes have the following effects.
Function. Meaning.
G17 It does not change planes and shows a warning about it.
G18 It has no effect (except when function G20 is active).

perpendicular to the plane, which coincides with the longitudinal axis of the tool, the one on
which tool length compensation is applied.
G17 Main plane formed by the first axis (abscissa), second (ordinate) and third axis
(perpendicular) of the channel.

ORIGIN SELECTION
With this CNC, it is possible to program movements in the machine reference system or apply
offsets in order to use reference systems referred to the fixtures or the part without having
to change the coordinates of the different points of the part in the program.
There are three different offset types; fixture offset, zero offsets and PLC offsets. The CNC
may have several of these offsets active at the same time, in that case, the system coordinate
origin being used will be defined by the sum of the active offsets.

Zero offsets and coordinate transformations
When executing a movement referred to machine zero, the CNC ignores the active offsets
(except the PLC offset), the kinematics and cartesian transformations; therefore, the
movement is carried out in the machine reference system. Once the movement has ended,
the CNC restores the offsets, kinematics and cartesian transformations that were active.
The programmed movements do not admit polar coordinates, nor other kinds of
transformations such as mirror image, coordinate (pattern) rotation or scaling factor. While
the #MCS function is active, functions for setting a new origin such as G92, G54-G59, G158,
G30, etc. are not admitted either.

Tool radius and length compensation
Tool radius and length compensation is also canceled during the movements referred to

When moving with respect to machine reference zero, the G70 or G71 units

Use this function with caution. Changing the machine coordinate can cause the axes to exceed the
travel limits during the movement.
Function G174 may be used to set the machine coordinate of an axis or spindle; in other
words, temporarily set a new machine zero. The new machine coordinate stays active until
the axis or spindle is homed; then, the CNC restores the original machine reference zero
(set in the machine parameters).

Programming the function.
Program function G174, and then the machine coordinate of a single axis or spindle. With
this function only the machine coordinate of an axis or spindle may be set; to set the machine
coordinates of several, program one G174 for each one of them.
When setting the machine coordinate, the CNC ignores the G70/G71 units
(inches/millimeters) selected by the user and uses the unit system pre-defined at the CNC
(parameter INCHES). The CNC also ignores all the other options, radius/diameter, mirror
image, scaling factor, etc.

Considerations and limitations.
Function G174, by itself, does not cause any axis or spindle movement. After executing
function G174, the CNC considers that the axis or sp indle is homed and verifies that it is within
the software travel limits.
The CNC does not allow setting the machine coordinate on slaved axes, grantry, tandem or
on axes that are part of the active kinematics or active transform. The CNC permits setting
the machine coordinate for tandem axes. Before setting the new machine coordinate, the
CNC checks that the axis or spindle is in position and it is not synchronized, if that's not the
case, it issues an error message.
On Sercos axes, function G174 also resets the coordinate of the drive. Setting the machine coordinates
on position-Sercos axes requires drive version V6.20 or newer.
Properties of the function and Influence of the reset, turning the
CNC off and of the M30 function.
Function G174 is modal. This function is neither affected by functions M02 and M30 nor by
a reset, by an emergency or by turning the CNC off. On power-up, the CNC assumes the
machine coordinates that were active when the CNC was turned off.

5.3 Fixture offset
With fixture offsets, it is possible to select the fixture system to be used (when having more
than one fixture). When applying a new fixture offset, the CNC assumes the point set by the
new selected fixture as the new fixture zero.
Defintion
In order to apply a fixture offset, it must have been previously set. To do that, the CNC has
a table where the operator may define up to 10 different fixture offsets. The table data may
be defined:
• Manually from the CNC's front panel (as described in the Operating Manual).
• By program, assigning the corresponding value (of the "n" offset and of the "Xn" axis)
to the "V.A.FIXT[n].Xn" variable.
5.
Fixture offset
Activation
Once the fixture offsets have been defined in the table, they may be activated via program
by assigning to the "V.G.FIX" variable, the offset number to be applied.
Only one fixture offset may be active at a time; therefore, when applying a fixture offset, it
will cancel the previous one. Assigning a value of "V.G.FIX=0" will cancel the active fixture
offset.

5.5 Zero offsets (G54-G59/G159)
Using zero offsets, it is possible to place the part zero in different positions of the machine.
When applying a zero offset, the CNC assumes as the new part zero the point defined by
the selected zero offset.
Defining zero offsets.
In order to apply a zero offset, it must have been previously defined. To do that, the CNC
has a table where the operator may define up to 99 different zero offsets. The table data may
be defined manually (as described in the operating manual) or via program (using variables).
The OEM may have configured the zero offset table in one of the following ways (machine
parameter FINEORG).
• Each zero offset has a single value. When executing function G159, the CNC assumes
this value as the new zero offset.
• Each zero offset has a coarse (or absolute) value and a fine (or incremental) value. When
executing function G159, the CNC assumes as new zero offset the sum of both parts.

5.5.2 Incremental zero offset (G158)
When applying an incremental zero offset, the CNC adds it to the absolute zero offset active
at a time.
Programming
Incremental zero offset are defined by program using function G158 followed by the values
of the zero offset to be applied on each axis. To cancel the incremental zero offset, program
function G158 without axes in the block. To only cancel the incremental zero offset on
particular axes, program an incremental offset of "0" on each of those axes.

5.5.3 Excluding axes in the zero offset (G157)
Excluding axes allows to select on to which axes the next absolute zero offset will not be
applied. After applying the zero offset, the programmed axis exclusion is canceled and it has
to be programmed again in order to apply it again.
Activation
Axis exclusion must be programmed using function G157 followed by the axes and the value
indicating whether that axis is excluded (<axis>=1) or not (<axis>=0).
The exclusion may also be activated by programming only the axes affected by the exclusion
after function G157.
The exclusion and the zero offset may be programmed in the same block. In that case, the
exclusion will be activated before applying the zero offset.

are always applied on to all the axes. Likewise, neither fixture offsets nor PLC offsets are
affected.

Function G157 is modal and it remains active until an absolute zero offset is applied.
On power-up or after an EMERGENCY, the CNC does not assume any axis exclusion.

5.7 Polar origin preset (G30)
Function G30 may be used to preset any point of the work plane as the new polar origin. If
not selected, it assumes as polar origin the origin of the active reference system (part zero).
Programming
The polar origin preset must be programmed alone in the block. The programming format
is "G30 I J", where:
They define the abscissa and ordinate of the new polar origin. They must be defined in absolute
I, J
coordinates referred to part zero.
When programmed, both parameters must be programmed.
If not programmed, it will assume the current tool position as the polar origin.
Therefore, function G30 may be programmed as follows:
G30 I J It assumes as the new polar origin the point whose abscissa is "I" and ordinate "J" referred
to part zero.
G30 The current tool position is assumed as the new polar origin.

TECHNOLOGICAL FUNCTIONS
6.1 Machining feedrate (F)
The machining feedrate may be selected by programmed using the "F" code which remains
active until another value is programmed. The programming units depend on the active work
mode (G93, G94 or G95) and the type of axis being moved (linear or rotary).
G94 - Feedrate in millimeters/minute (inches/minute).
G95 - Feedrate in millimeters/revolution (inches/revolution).
G93 - Machining time in seconds.
The programmed "F" is effective in linear (G01) or circular (G02, G03) interpolations.
Movements in G00 (rapid traverse) are executed in rapid regardless of the programmed "F"
value.
6
Movement without programmed feedrate.
In principle, the CNC will show the corresponding error when programming a movement in
G01/G02/G03 without having set a feedrate.
Optionally, the manufacturer may have configured the CNC to make the movements at the
maximum machining feedrate, set by machine parameter MAXFEED.
Feedrate limitation.
The manufacturer may have limited the maximum feedrate with machine parameter
MAXFEED. When trying to exceed the maximum feedrate via part-program, via PLC or from
the operator panel, the CNC limits the feedrate to the maximum value set without showing
any error message or warning.
If this parameter is set to zero, the machining feedrate is not limited and the CNC assumes
the one set for G00 as the maximum feedrate.
Variable to limit the feedrate via PLC.
(V.)[n].PLC.G00FEED is a variable that may be written from the PLC to set, at a particular
moment and in real time, the maximum feedrate of the channel for any type of movement.
Feedrate regulation.
The programmed feedrate "F" may be varied between 0% and 200% using the selector switch
on the CNC's operator panel or it may be selected by program or by PLC. However, the
maximum override is limited by the machine manufacturer [G.M.P. "MAXOVR"].
CNC 8070
When making movements in G00 (rapid traverse), the feedrate override percentage will be
fixed at 100% or it may be varied between 0% and 100% depending on how the machine
manufacturer has set [G.M.P. "RAPIDOVR"].
When carrying out threading operations, the feedrate percentage will be fixed at 100% of
the programmed feedrate.

Programming manual
Understanding how the CNC calculates the feedrate.
The feedrate is measured along the tool path, either along the straight line (linear
interpolations) or along the tangent of the indicated arc (circular interpolations).
When only the main axes are involved in the interpolation, the relationship between the
components of the feedrate on each axis and the programmed "F" is the same as between
the displacement of each axis and the resulting programmed displacement.
Machining feedrate (F)
TECHNOLOGICAL FUNCTIONS
CNC 8070
When rotary axes are involved in the interpolations, the feedrate of these axes is calculated
so the beginning and the end of their movement coincides with the beginning and the end
of the main axes. If the feedrate calculated for the rotary axis is greater than the maximum
allowed, the CNC will adapt the programmed "F" so the rotary axis can turn at its maximum
speed.

6.2.1 Feedrate programming units (G93/G94/G95)
The functions related to programming units permit selecting whether mm/minute

Programming
The functions related to programming units are:

G95 millimeters (inches)/revolution degrees/revolution
G93 seconds seconds
G94
Feedrate in millimeters/minute (inches/minute).
After executing G94, the CNC interprets that the feedrates programmed with the "F" code
are in millimeters/minute (inches/minute). If the moving axis is rotary, the CNC interprets that
the programmed feedrate is in degrees/minute.

G95
Feedrate in millimeters/revolution (inches/revolution)
After executing G95, the CNC interprets that the feedrates programmed with the "F" code

the CNC interprets that the programmed feedrate is in degrees/revolution.
If the spindle does not have an encoder, the CNC will use the programmed theoretical rpm
to calculate the feedrate. This function does not affect the movements in G00 which are
always executed in millimeters/minute (inches/minute).
G93
Machining time in seconds
After executing G93, the CNC interprets that the movements must be carried out in the time
