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 the following 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.

SOFTWARE OPTIONS.

Some of the features described in this manual are dependent on the acquired software options. The active

software options for the CNC can be consulted in the diagnostics mode (accessible from the task window

by pressing [CTRL] [A]), under software options. Consult Fagor Automation regarding the software options

available for your model.

Software option Description.

SOFT ADDIT AXES Option to add axes to the default configuration.

SOFT ADDIT SPINDLES Option to add spindles to the default configuration.

SOFT ADDIT TOOL MAGAZ Option to add magazines to the default configuration.

SOFT ADDIT CHANNELS Option to add channels to the default configuration.

SOFT 4 AXES INTERPOLATION LIMIT Limited to 4 interpolated axes.

SOFT DIGITAL SERCOS Option for a Sercos digital bus.

SOFT DIGIT NO FAGOR Option for a non-Fagor digital servo.

SOFT THIRD PARTY I/Os Option to enable non-Fagor remote modules.

SOFT OPEN SYSTEM Option for open systems. The CNC is a closed system that

offers all the features needed to machine parts.

Nevertheless, at times there are some customers who use

third-party applications to take measurements, perform

statistics or other tasks apart from machining a part.

This feature must be active when installing this type of

application, even if they are Office files. Once the

application has been installed, it is recommended to close

the CNC in order to prevent the operators from installing

other kinds of applications that could slow the system

down and affect the machining operations.

SOFT i4.0 CONNECTIVITY PACK Options for Industry 4.0 connectivity. This option provides

various data exchange standards (for example, OPC UA),

which allows the CNC (and therefore the machine tool) to

be integrated into a data acquisition network or into a MES

or SCADA system.

SOFT EDIT/SIMUL Option to enable edisimu mode (edition and simulation)

on the CNC, which can edit, modify and simulate part

programs.

Programming manual.

CNC 8070

(REF: 2102)

SOFT TOOL RADIUS COMP Option to enable radius compensation. This

compensation programs the contour to be machined

based on part dimensions without taking into account the

dimensions of the tool that will be used later on. This

avoids having to calculate and define the tool paths based

on the tool radius.

SOFT PROFILE EDITOR Option to enable the profile editor in edisimu mode and in

the cycle editor. This editor can graphically, and in a

guided way, define rectangular, circular profiles or any

profile made up of straight and circular sections an it can

also import dxf files. After defining the profile, the CNC

generates the required blocks and add them to the

program.

SOFT RTCP Option to enable dynamic RTCP (Rotating Tool Center

Point) required to machine with 4, 5 and 6 axis kinematics;

for example, angular and orthogonal spindles, tilting

tables, etc. The RTCP orientation of the tool may be

changed without modifying the position occupied by the

tool tip on the part.

SOFT C AXIS Option to enable C-axis kinematics and associated

canned cycles. The machine parameters of each axis or

spindle indicate whether it can operate as a C axis or not.

For this reason, it is not necessary to add specific axes to

the configuration.

SOFT TANDEM AXES Option to enable tandem axle control. A tandem axis

consists of two motors mechanically coupled to each

other forming a single transmission system (axis or

spindle). A tandem axis helps provide the necessary

torque to move an axis when a single motor is not capable

of supplying enough torque to do it.

When activating this feature, it should be kept in mind that

for each tandem axis of the machine, another axis must

be added to the entire configuration. For example, on a

large 3-axis lathe (X Z and tailstock), if the tailstock is a

tandem axis, the final purchase order for the machine

must indicate 4 axes.

SOFT SYNCHRONISM Option to enable the synchronization of paired axes and

spindles, in speed or position, and through a given ratio.

SOFT HSSA II MACHINING SYSTEM Option to enable the HSSA-II (High Speed Surface

Accuracy) algorithm for high speed machining (HSC).

This new HSSA algorithm allows for high speed

machining optimization, where higher cutting speeds,

smoother contours, a better surface finishing and greater

precision are achieved. The HSSA-II algorithm has the

following advantages compared to the HSSA-I algorithm.

• Advanced algorithm for point preprocessing in real

time.

• Extended curvature algorithm with dynamic

limitations. Improved acceleration and jerk control.

• Greater number of pre-processed points.

• Filters to smooth out the dynamic machine behavior.

SOFT TANGENTIAL CONTROL Option to enable tangential control. "Tangential Control"

maintains a rotary axis always in the same orientation with

respect to the programmed tool path. The machining path

is defined on the axes of the active plane and the CNC

maintains the orientation of the rotary axis along the entire

tool path.

SOFT DRILL CYCL OL Option to enable ISO drilling cycles (G80, G81, G82,

G83).

SOFT PROBE Option to enable functions G100, G103 and G104 (for

probe movements) and probe canned cycles (which help

to measure part surfaces and to calibrate tools). For the

laser model, it only activates the non-cycle function G100.

The CNC may have two probes; usually a tabletop probe

to calibrate tools and a measuring probe to measure the

part.

SOFT FVC STANDARD

SOFT FVC UP TO 10m3

SOFT FVC MORE TO 10m3

Options to enable volumetric compensation. The

precision of the parts is limited by the machine

manufacturing tolerances, wear, the effect of

temperature, etc., especially on 5-axis machines.

Volumetric compensation corrects these geometric errors

to a larger extent, thus improving the precision of the

positioning. The volume to be compensated is defined by

a point cloud and for each point the

error to be corrected is measured. When mapping the total

work volume of the machine, the CNC knows the exact

position of the tool at all times.

There are 3 options, which depend on the size of the

machine.

• FVC STANDARD: Compensation for 15625 points

(maximum 1000 points per axis). Quick calibration

(time), but less precise than the other two, but

sufficient for the desired tolerances.

• FVC UP TO 10m3: Volume compensation up to 10 m³.

More accurate than FVC STANDARD, but requires a

more accurate calibration using a Tracer or Tracker

laser).

• FVC MORE TO 10m3: Volume compensation greater

than 10 m³. More accurate than FVC STANDARD, but

requires a more accurate calibration using a Tracer or

Tracker laser.

SOFT PWM CONTROL Option to enable PWM (Pulse - Width Modulation) control

on laser machines. This feature is essential for cutting

very thick sheets, where the CNC must create a series of

PWM pulses to control laser power when drilling the initial

point.

This function is only available for Sercos bus control

systems and must also use one of the two fast digital

outputs available from the central unit.

SOFT GAP CONTROL Option to enable gap control, which makes it possible to

set a fixed distance between the laser nozzle and the

sheet surface with the use of a sensor. The CNC

compensates the difference between the distance

measured by the sensor and the programmed distance

with additional movements on the axis programmed for

the gap.

SOFT DMC Option to enable the DMC (Dynamic Machining Control).

DMC adapts the feedrate during machining to maintain

the cutting power as close as possible to ideal machining

conditions.

SOFT FMC Option to enable the FMC (Fagor Machining Calculator).

The FMC application consists of a database of materials

to be machined and machining operations, with an

interface to choose suitable cutting conditions for these

operations.

SOFT FFC Option to enable the FFC (Fagor Feed Control). During

the execution of a canned cycle of the editor, the FFC

function makes it possible to replace the feedrate and

speed programmed in the cycle with the active values of

the execution, which are acted upon by the feed override

and speed override.

SOFT 60/65/70 OPERATING TERMS Option to enable a temporary user license for the CNC,

which is valid until the date set by the OEM. While the

license is valid, the CNC will be fully operational

(according to the purchased software options).

SOFT MANUAL NESTING Option to enable nesting in the automatic option. Nesting

consists of creating a pattern on the sheet material using

previously defined figures (in dxf, dwg or parametric files),

so as to use most of the sheet as possible. Once the

pattern has been defined, the CNC creates a program.

During manual nesting, the operator distributes the parts

on top of the sheet material.

Software option Description.

SOFT AUTO NESTING Option to enable nesting in the automatic option. Nesting

consists of creating a pattern on the sheet material using

previously defined figures (in dxf, dwg or parametric files),

so as to use most of the sheet as possible. Once the

pattern has been defined, the CNC creates a program.

During automatic nesting, the application distributes the

figures on the sheet material and optimizes the spaces.

SOFT IEC 61131 LANGUAGE IEC 61131 is a PLC programming language that is very

popular in alternative markets, which is slowly entering

into the machine-tool market. With this feature, the PLC

may be programmed either in the usual Fagor language

or in IEC 61131 format.
