14 Improved non-random tool magazine management

When the tool changer is configured as non-random, the tools must
be placed in the tool magazine table in the pre-established order (P1
T1, P2 T2, P3 T3, P4 T4, etc.).

With this improvement, it is possible to assign several tools to each
tool position.

15 Improved drive parameter management

From this version on, it also possible to save and load into a
peripheral device or PC the drive parameter tables via Sercos serial
line.

For that, select the parameter page of the desired drive at the CNC
and press the relevant softkey.

A file saved from the CNC via WINDNC may be loaded into the drive
via DDSSETUP and vice versa.

16 User and OEM arithmetic parameters

There are now two new ranges of global arithmetic parameters.

User parameters Range: P1000 - P1255.
OEM parameters Range: P2000 - P2255

By default 0

For compatibility with previous versions, global arithmetic
parameters P100-P299 are maintained and may be used by the

There are now 2 new tables of global arithmetic parameters.

Arithmetic parameter tables available:

GUP Global parameters P100-P299
USP User parameters P1000-P1255
OEP OEM parameters P2000 - P2255

being used.

0 rectangular leadscrew backlash peak
1 exponential type of leadscrew backlash peak

A finer tuning of the leadscrew backlash consists in testing the circle
geometry and watch for internal peaks when changing quadrants
(left figure). In these cases, it is recommended to set bit 15 of g.m.p.
“ACTBAKAN (P144)” to "1" to eliminate the internal peaks.

Under these conditions, the CNC eliminates the leadscrew backlash
peak as soon as it detects a movement reversal. If the internal peaks
are not eliminated, adjust the leadscrew backlash compensation
better.

18 Functions associated to machine safety

18.1 Limit the feedrate of the axes and the spindle speed

It is possible to limit the feedrate of the axes and the spindle turning
speed.

8040 CNC

FLIMIT (P75)
SLIMIT (P66)

The a.m.p. "FLIMIT" sets the maximum feedrate for each axis and
the s.m.p. "SLIMIT" sets the maximum turning speed for each
spindle.

FLIMITAC (M5058)

When the PLC sets this signal high, it limits the feedrate of all the
axes. It does not let any feedrate to exceed the value set by the
corresponding a.m.p. "FLIMIT (P75)" .

SLIMITAC (M5059)

When the PLC sets this signal high, it limits the speed of all the
spindles. It does not let any feedrate to exceed the value set by the
corresponding s.m.p. "SLIMIT (P66)" .

The limitation is applied in all work modes, including the PLC
channel. When the mark is high, the CNC applies the limitation and
when going low, it restores the programmed F or S.

When the spindle moves with PLCCNTL, the spindle limitation is
ignored.

18.2 Cycle Start disabled by hardware errors

If when pressing the Cycle-Start key, a hardware error is detected
(Sercos board error, CAN board error, etc.), the CNC issues the
corresponding error message and does not allow executing or
simulating the program.

18.3 Maximum spindle machining speed.

The following safety regulation requires limiting the spindle speed on
lathes:

"A program will not be executed in machining mode unless the maximum
spindle speed value for the part is entered as well as the proper
maximum speed for the part holding fixture for the machine.

If the operator does not enter or validate these speeds every time the
program is changed, it will not be possible to execute the program
machining mode.

The speed cannot exceed the lower speed among the maximum set by
parameter, the maximum set by program and the maximum entered by
hand

A new variable (MDISL) associated with speed limits is now
available to make this safety maneuver easier. It is read-write from
the PLC and read-only from DNC and CNC.

This variable is also updated with the programmed S value, in the

When programming "G92 S" in MDI mode

•

When programming "G92 S" in ISO code in TC mode.

•

In TC mode, when a new speed limit is defined in the "SMAX"

•

field.

The speed limits entered via CNC, PLC (PLCSL) and DNC (DNCSL)
keep the same functionality and priority unaffected by the new
MDISL variable; in other words, the CNC keeps limiting the spindle
speed like until now.

In order to comply with the safety regulation, it is recommended to
manage from the PLC the variables associated with speed limits as
shown in the following example:

A new part-program cannot be executed without previously

•

entering the speed limit. Otherwise, a message will be displayed.

If the program is executed again, the limit does not have to be
entered again, it is only required when executing the program for
the first time.

While executing a program if a new limit is entered in MDI, the

•

new one will replace the previous one.

In independent TC cycles it is not required to enter the SMAX

•

because it is already defined in each cycle.

19 Axes (2) controlled by a drive

Until this version, when having 2 axes controlled by a single drive,
the polarity of the analog output (command sign) always
corresponded to that of the main axis.

From this version on, since sometimes the turning direction of the
two axes may be different, the sign of the command for each axis will
taken into account [the one set by a.m.p “LOOPCHG (P26)”].

This new version is not compatible with previous versions.
On machines having axes controlled by a single drive the secondary
axis might run away.
Before installing the new software, make sure that the a.m.p.
"LOOPCHG (P26)" of the associated axis has the same value as that of
the main axis.

20 Mandatory home search

The CNC forces a home search on an axis by setting the relevant
REFPOIN* mark low in the following cases:

On CNC power-up

•

After executing SHIFT RESET

•

When the feedback is direct through the axes board and a

•

feedback alarm occurs.
When losing feedback count via Sercos due to broken

•

communication. Difference greater than 10 microns (0.00039")
or 0.01º

When changing machine parameters that affect the memory

•

distribution, for example: number of axes.

In all these cases, a home search must be carried out so the signal
is set back high.

waiting for the execution of an M06 to become active.

This way, it is possible to resume the tool change from the PLC and

variable.

To allocate a magazine position to the tool that is considered active
by the CNC and is physically in the tool magazine, proceed as
follows:

Synchronize a PLC

axis with a CNC

axis

22 Synchronize a PLC axis with a CNC axis

To synchronize an axis of the PLC channel with another one of the
CNC channel (main channel), set a.m.p. SYNCHRO (P3) of the PLC
axis indicating which axis it must synchronize with.

Axis synchronization is carried out from the PLC by activating the
general input "SYNCHRO" of the axis to be coupled as slave (PLC
axis).

To assure that both axes are stopped when they are being
synchronized, we suggest:

To execute a special M function at the CNC so the PLC executes

•

another M function in the PLC channel and activates the general
input "SYNCHRO".

The M function of the main channel must not end until the PLC's

•

M function execution is completed and the ENABLE signal of the
slave axis is set high.

Once both axes are synchronized, it won't be possible to program
movements of the PLC axis. Otherwise, error 1099 will be issued:
"Do not program a slaved axis".

During synchronization, it does not check whether the PLC axis gets
in position or not. For this reason:

The logic output "ENABLE" of the PLC axis is activated (allowing

•

motion).

Page 14 of 46

The logic output "INPOS" of the PLC axis is deactivated (the axis

•

is NOT in position).

General input "INHIBIT" of the PLC axis is ignored, thus not being

•

possible to prevent it from moving.

The execution of the movement of the synchronized slave axis

•

cannot be aborted even by activating the general input
"PLCABORT".

If an error occurs canceling the "ENABLE" logic outputs of all the
axes, it also cancels the synchronization.

To end synchronization, cancel the "SYNCHRO" general input of the
PLC axis.

To assure that the PLC axis recovers its position after the
synchronization, it is recommended to use other 2 special M
functions, one at the CNC and another one at the PLC.

23 Minimum step "L" in cycles G83, G60 and G61

A new "L" parameter has been added to the drilling cycles G83, G60
and G61.

G83 X Z I B D K H C L R
G60 X Z I B Q A J D K H C S L R
G61 X Z I B Q A J D K H C S L R

It is an optional parameter used with "R" values other than "1". It
indicates the minimum value allowed for the drilling peck. If not
programmed, a value of 0 mm is assumed.

A new "V" parameter has been added to the tapping cycles G86 and

G86-G87: X Z Q R I B D L C J A V

It is an optional parameter that indicates the number of thread
entries to make. If not programmed or programmed with a value of
"0", it means that the thread has only one entry.

25 Error register

The "CNC" screen of the "STATUS" mode offers the softkey: [BB].

Pressing this softkey displays the error history indicating the error
number and when it occurred.

This information is very useful to the service technician. Pressing the
[SAVE] softkey requests the number of the CNC program to store
that information.

If the service department asks you for that program, transfer it to a
PC via DNC and send it to the corresponding address via internet.

CAXGAIN (P163)

This g.m.p. lets the OEM decide whether these gains are to be
canceled or not.

With “CAXGAIN (P163) =1” and high values of FFGAIN and
DERGAIN the machine could be jerky depending on the type of part
being machined. In these cases, we suggest to select a gain range
whose FFGAIN AND DERGAIN values small or zero.

27 Path JOG mode

It is similar to the "Path Handwheel" mode.

The "Path Handwheel" mode acts at the Handwheel position of the
selector switch whereas the "Path JOG" acts at the continuous and
incremental jog positions of the selector switch.

"Path JOG" may be used to act upon the jog keys of an axis to move
both axes of the plane at the same time for chamfering (straight
sections) and rounding (curved sections).

The CNC assumes as "Path JOG" the keys associated with the Z
axis.

Fagor Sercos drives, it is also possible to set the parameters of the
drive.

When requesting information (variable or parameter) of a drive that
is not connected via Sercos or when having an old software version,
the message "Variable does not exist" will be displayed.

Changing the machine parameters of the CNC and the drive
requires a password.

Once data capture has ended, or has been interrupted, it is possible
to analyze the signals and modify the parameters that have been
previously selected, in order to improve the machining conditions.

Capture data, analyze it and modify the parameters again until
achieving the best machining conditions.

Operation

Execute endless repetitive movements.

After adjusting the axis separately, readjust the interpolating axes
together.

It is up to the user to judge what the best adjustment is, the
oscilloscope function is an assistance tool.

To enter or modify a data on the screens, it must be selected and it
must have the editing focus.

To select another editable data or field, use the [Ï] [Ð]. It is a rotary
selection, if the first element is selected on the screen, when
pressing [Ï] the focus goes to the last one, whereas if the last
element is selected, when pressing [Ð] the focus goes to the first
one.

Not all the data may be edited, only the ones that may be selected,
those having the focus. There are two types of editable fields:

Editable values:

They may be assigned a value, sometimes numerical (numbers
only) and sometimes alphanumerical (numbers and letters).
Before validating the data, it is checked; if the data is incorrect, it
is rejected and a warning message is issued.

When a parameter is changed on the "Parameter Editing" screen,
the CNC machine parameter table and the drive's work parameters
are updated. The [Save Parameters] softkey is also activated on the
"Configuration - Parameters" screen.

We suggest to access that screen and press the [Save Parameters]
softkey to save the parameter tables that have been changed, those
of the CNC into the CARDA and those of the drive in its FLASH. If
only the CNC parameters have been changed, the drive tables
remain unchanged and vice versa.

Once the values saved are the same as the ones edited last, the
softkey disappears until a new modification is made.

The "hidden" channels are not shown graphically (they are not
shown on the screen after the data capture). It is useful when using
this channel to set the trigger condition.

keys or [page up] [page down] to move the signal or press one of
these keys:

[U] To move it up as high as possible
[D] To move it down as low as possible
[0] To center it
[X] for the CNC to scale it automatically.

When auto-scaling a channel, the system sets the right vertical scale
and offset so the signal shows as big as possible within its graphic
strip.

To modify the time base of all the signals, use the [Ï] [Ð] keys to
place the focus in the "t/div" field. Then use the [Í] [Î] keys or
[page up] [page down] to select one of the permitted values or press
[X] for auto-scaling.

To select another portion of the sample use the [Ï] [Ð] keys to place
the focus in the "Win" field. Then use the [Í] [Î] keys or [page up]
[page down] to move the signal or press one of these keys:

[F] To show the beginning of the trace (First)
[T] To show the trigger zone
[S] To show the final portion of the trace (Second)
[X] for the CNC to scale it automatically.

30.3 Analysis

To analyze, using 2 cursors, each signal of the last data capture.

The right side of the screen shows:

Next to each variable, the value (V1 and V2) of the signal in the

•

position of each cursor and the difference between them (∆v).

The position, in milliseconds, of each cursor (C1 and C2) and the

•

time difference between them (∆t)

To select the first or second cursor, use the teclas [Ï] [Ð] keys to
place the focus in the "C1" or "C2" fields respectively. Then use the
[Í] [Î] keys or [page up] [page down] to move the signal or press
one of these keys:

[F] To show the beginning of the trace (First)
[T] To show the trigger zone
[S] To show the final portion of the trace (Second)
[X] for the CNC to scale it automatically.

To select another portion of the sample use the [Ï] [Ð] keys to place
the focus in the "Win" field. Then use the [Í] [Î] keys or [page up]
[page down] to move the signal or press one of these keys:

[F] To show the beginning of the trace (First)
[T] To show the trigger zone
[S] To show the final portion of the trace (Second)
[X] for the CNC to scale it automatically.

30.4 Parameters

Holding the [Í] [Î] keys pressed accelerates the movement.

Oscilloscope

function

To assign new values to the machine parameters of the CNC and
drive that have been defined in the "Configuration-Parameters"
screen.

8040 CNC

The machine parameters of the axis or the spindle are updated
according to the criteria defined in the previous tables, the rest of the
parameters are updated according to the general criteria:

// It is necessary to press the keystroke sequence: "Shift -

Reset" or turn the CNC off and back on.

/ Just press Reset.

The rest of the parameters (those unmarked) will be updated
automatically, only by changing them.

If the password to the machine parameters has been defined
(SETUPPSW), it will be requested when modifying a parameter for
the first time. If entered correctly, it is stored in memory and it is not
requested again unless the CNC is turned off. If the password is
wrong, the parameter cannot be modified and it will be requested
again the next time.

When a parameter is changed, the CNC machine parameter table
and the drive's work parameters are updated. The [Save
Parameters] softkey is also activated on the "Configuration ­Parameters" screen.

We suggest to access that screen and press the [Save Parameters]
softkey to save the parameter tables that have been changed, those
of the CNC into the CARDA and those of the drive in its FLASH. If
only the CNC parameters have been changed, the drive tables
remain unchanged and vice versa.

Once the values saved are the same as the ones edited last, the
softkey disappears until a new modification is made.

30.5 Actions

It is available on the following screens: "Parameter Editing",
"Analysis" and "Scales /Offsets".

It is very useful when not having an alpha-numeric keyboard (TC or
TCO operator panels) because it shows several softkeys to change
the data of each field (amplitude of the signals, vertical movement,
time base, position of the cursors, etc.)

30.6 Begin

It is available on the following screens: "Parameter Editing",
"Analysis" and "Scales /Offsets".

It captures data according to the conditions set on the
"Configuration" screen and enables the following softkeys:

[Stop]

interrupts the capture and shows the data collected until then.

[Continuous Stop]

available when the capture is continuous. It interrupts the
capture and shows the last full trace.

Once data capture has ended, or has been interrupted, it is possible
to analyze the signals and modify the parameters that have been
previously selected, in order to improve the machining conditions.

Capture data, analyze it and modify the parameters again until
achieving the best machining conditions.
