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.

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.

Page 25 of 46

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.

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.

Oscilloscope

function

Page 26 of 46

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.

31 TC model. Execute a part-program

After accessing the list of stored part-programs and selecting the
program to be executed from the left column, it is possible to:

Execute the whole part-program.

1.

(Start)

Position, on the left column, over the desired program and press
(Start).

Subroutine 9998 is executed before the part-program and
subroutine 9999 after the part-program.

Execute a portion of the part-program.

2.

Select the program from the left column and the operation (on the
right column) from which to begin executing the part program and
press the (Start) key.

In this case, the initial 9998 subroutine is not executed, only the
part-program and the 9999 subroutine are execute.

Execute the part-program starting at the first operation.

3.

Select the program from the left column and the first operation
from the right column and press the (Start) key.

Subroutine 9998 is executed before the part-program and
subroutine 9999 after the part-program.

Note:

Programs created in ISO mode do not have subroutines
9998 and 9999.

32 TC model. Maintain F, S y Smax on power up

8040 CNC

MAINTASF (P162)

This g.m.p indicates whether on CNC power-up, the F, S and Smax
values are maintained or initialized.

0 They are initialize with the values of F=0, S=0 and Smax=0
1 F, S and Smax maintain the values they had in the last

machining operation.

With “MAINTASF (P162)=1”, the CNC acts as follows:

It assumes the G94/G95 feedrate set by g.m.p. "IFEED (P14)",

•

but it restores the F in mm/min (G94) and the F in mm/rev (G95)
programmed last.

It maintains the feedrate type G96/G97 used last, but it restores

•

the S in rev/min (G97) and the S in m/min (G96) programmed
last.

entered to define the number of entries. It is an optional parameter
that goes at the end of the cycle and if not programmed or
programmed with a "0" value, it means that the thread only has one
entry. The syntax of the ISO instructions is now:

40 TC model. Modifications in the profile cycle

Minimize the machining time in XC and ZC profile cycles

Until this version, after each roughing pass, the tool withdrew to the
safety position.

From this version on, this movement does not take place, thus
minimizing the execution time.

Starting point coordinates in XC and ZC profile cycles

From this version on, the CNC does not request the coordinates of
the starting point (X, C) because it assumes the first point of the
profile as the starting point of the cycle.

Finishing stock in XC and ZC profile cycles

When the finishing operation is carried out with tool compensation,
the following data must be defined:

Depth stock (δx) or (δz).

•

Side stock (δ) and the number of passes (N) to remove that stock

•

It is machined as follows:

Roughing operation leaving the indicated side stock (δ) and

Cards with software versions older than V7.11

3 Smooth stop in probing move (G75/G76)

From this version on, a smooth stop may be defined for probing
moves. When the probe pulse is detected, the following error is not
reset, thus making the probe stop more smoothly.

selects the selected type of stop.

1 Smooth stop.

By default 0

When setting the smooth stop, a.m.p "DERGAIN (P25)" and s.m.p.
"FFGAIN (P25)" should be set to zero. This may be done by setting
the range of gains through g.m.p. "ACTGAIN2 (P108)" with the bit

how to machine the corner where the tool offset is being changed.
This corner may be machined in square corner (sharp) or rounded.

This parameter is only taken into consideration when working in
round corner. When working in square corner, the corner is always
machined in square corner mode.

We recommend to set axis parameter POSINREF=NO. Otherwise,
it generates a movement to the position defined by axis parameter
REFVALUE.

• The parameters related to the counting of pulses (feedback) are
at the drive. At FAGOR drives, the parameters are:

GP10 Feedback2Type

7 Leadscrew error compensation in both directions

Bidirectional leadscrew error compensation

From this version on, it is possible to define a different leadscrew
compensation for each moving direction.

This is defined in the leadscrew compensation tables. Each row of
the table contains the following data:

• The position of the axis to be compensated.

• The amount of error of the axis at that point. In the positive

direction.

• The amount of error of the axis at that point. In the negative
direction.

For each axis position, define the amount of error to compensate in
both directions. If the error in the negative direction has a zero value
in all positions, it is assumed that the error defined for the positive
direction is valid for both directions.

New management

coded reference

mark (I0)

Likewise, the compensation defined in a single direction or for both,
the compensation error at the reference point does not need to be
zero.

• When updating from a version older than V8.11.
It maintains the values of the error in the positive direction of the

tables and assigns a zero error in the negative direction to all the
points.

• When changing to a version older than V8.11.
It maintains the error values in the tables in the positive direction, but

it loses the ones in the negative direction.

TC work mode

1.2 GENERAL

It has all the performance features of the T model plus the specific features of the TC mode.
For example, the setting of the numerical Control must be done in "T" mode.
In the TC operating mode the programs P900000 to P999999 are reserved for the CNC itself, that is,

these cannot be used as part-programs by the user as they have a special significance.
Furthermore, to be able to work in TC mode, the CNC has to have in its memory programs P999997

and P999998, which are supplied by Fagor Automation.
Every time the CNC detects a new software version, updates these programs automatically and makes

a backup copy of the old ones in the "Memkey Card" (CARD A).
Also routines 0000 a 8999 are free for use and routines 9000 to 9999 are reserved for the CNC itself.
Some of the programs reserved for the CNC itself have the following meaning:

Warning: Programs P999997 and P999998 are associated with the software version.

Fagor Automation shall not be held responsible of any possible malfunction if
programs P999997 and P999998 have been deleted from memory or do not
correspond to the software version.

Some of the routines reserved for the CNC itself have the following meaning:

9998 Routine to be executed by the CNC at the beginning of each part-program.
9999 Routine to be executed by the CNC at the end of each part-program.

Every time a new part-program is edited the CNC adds a call to the corresponding
routine at the beginning and end of each program.

Warning Both subroutines must be defined by the machine manufacturer even if no operation

is to be carried out at the beginning or at the end of the part-program.
Otherwise, the CNC will issue an error when attempting to run a part-program.

Example of how to define subroutine 9998.
(SUB 9998) ; Definition of subroutine 9998.

; Programmed blocks defined by the machine manufacturer

(RET) ; End of subroutine

Chapter 1 - page 2

1. General Concepts

1.2 General

Some of the programs reserved for the CNC itself have the following meaning:

P999998 This is a routines program used by the CNC for interpreting the programs edited in TC

format and executing these afterwards.

Warning

No modifications of this program are allowed. If this program is
modified, Fagor Automation will not be held responsible for the
performance of the CNC.

If the manufacturer needs to create his own subroutines (home

search subroutine, tool change, etc. ...) as well as subroutines

9998 and 9999 should be included in another program, for
example P999999.

P999997 This is a text program which contains:

All the phrases and texts displayed on the different screens in the TC mode.
The help texts for the icons in work cycles shown at the bottom left side of the screen.
The messages (MSG) and errors (ERR) to be issued at the TC model.

All these texts, messages and errors may be translated into the desired language.
Points to consider:

All the lines of the program have to start with the character ";"
If a line starts with ";;", the CNC will understand that the whole line is a program
comment.
The format of a line is as follows:

";Nr. of text - explanatory remark (not displayed) - $Text to be displayed"

Examples

;; General text ...............................The CNC treats this as a remark

;;44 Feedrate $M/MIN .................The CNC treats this as a remark.

;44 $M/MIN ..................................This is message 44 and the text "M/MIN" is

displayed

;;44 Feedrate $M/MIN .................This is message 44, and has the explanatory

remark "Feedrate" which is not displayed and the
text

"M/MIN" is shown.
Notes regarding messages:
The format must be respected. Only the text after "SAVEMSG:" may be translated

Example:
Original: N9500(MSG"SAVEMSG: TURNING CYLE")
Translated: N9500(MSG"SAVEMSG: ZILINDRAKETA ZIKLOA")

Notes regarding errors:
The format must be respected. Only the text between quotes( "xxxx") may be

translated
Example:
Original: N9000(ERROR"Cycle with neither roughing nor finishing operation")
Translated: N9000(ERROR"Arbastatu eta Akabatu gabeko zikloa")

Warning

When modifying program 999997, it is recommended to make a
backup copy because the CNC replaces it every time another
language is selected or the software version is updated.

P998000 ... P998999 These are user-defined profile part-programs. In TC mode the user defines

them with 3 digits, (from 0 to 999) and the CNC saves these internally as P 998xxx.

1.2.1 System of coordinates

TC work mode

1.2.1 MANAGEMENT OF TEXT PROGRAM P999997

On power-up, the CNC copies the texts of program P999997 into the system memory.

It checks if program P999997 is in the user memory. If it is not, it looks in "CARD A", if it is not
there either, it assumes the ones provided by default and it copies them into the P999997 program
of the user memory.

If the mainland Chinese language is selected, program P999997 is ignored. It always assumes the
ones provided by default.

If when switching from M mode to MC or MCO mode, program P999997 cannot be found, because
it has been erased, it is re-initialized like after power-up.

After modifying the texts of program P999997, turn the CNC off and back on to assume the new texts.
When changing a language, software version or adding conversational modes MC, MCO (new

software features) the CNC carries out the following operations:

The texts that were being used are saved into "CARD A" as program P999993.
Program P999997 is erased from "CARD A"
The new default texts are assumed and are copied into program P999997 of the user memory.

When changing the texts, turn the CNC off and back on after modifying program P999997 so it
assumes the new texts.

1.6 HANDLING THE CYCLE-START KEY

In order to avoid unwanted executions when keying sequences not supported in the TC mode, the
CNC changes the color of the "CYCLE START" icon located at the top of the window from green
to grey and it shows a message indicating that it is an invalid action.

For example, if while a part-program is selected, "M3 Start" is pressed, (sequence not supported by
the TC model), the CNC displays a warning message and prevents the part-program from running
when detecting the "cycle start" key.

2.4 Jogging the axes

2.4.1 Continuous jog

TC work mode

2.4 JOGGING THE AXES

The axes of the machine can be moved in the following ways:

- [X] [target position] or [Z] [target position]

- continuous jog

- incremental jog

- jogging with an electronic handwheel

2.4.1 CONTINUOUS JOG

Place the left-hand switch in position and on the right-hand switch select the percentage (0%
to 120%) of the feedrate selected to be applied.

Continuous movement should be done axis to axis. To do this press the JOG
key for the direction of the axis to be moved.

The axis moves with a feedrate equal to the percentage (0% to 120%) of the «F»
feedrate selected.

If during movement the key is pressed the maximum feedrate possible is carried out, as is stated
in the “G00FEED” axis machine parameter. This feedrate will be applied as long as said key is

pressed, and when released the previous feedrate will be resumed.
Depending on the state of the “LATCHM” general logic input the movement will be made in the

following way:

* If the PLC sets this mark at a low logic level (0V), the axis will only move while the relevant
JOG key is pressed.

* If the PLC sets this mark at a high logic level (24V), the axis will start to move when the JOG
key is pressed and will not stop until said JOG key or another JOG key is pressed again, and in
this case the movement is transferred to what is indicated by the next key pressed.

When operating with feedrate "F" in millimeters/revolution the following cases may arise:
a) The spindle is started. or

The CNC moves the axes to the F programmed.

b) The spindle is stopped but there is a spindle speed S selected.

The CNC calculates the feedrate in millimeters/minute corresponding to the theoretical "S" and
moves the axis.
For example, if «F 2.000» and «S 500»:

Feedrate = F (mm/rev.) x S (rev/min)= 2 x 500 = 1000 mm/min
The axis moves at a feedrate of 1000 in millimeters/minute.

c) The spindle is stationary and there is no spindle speed S selected.

If feedrate F has value 0, the CNC moves the axes at rapid feedrate.
If feedrate F has any other value, the axes will only be able to be moved if key is pressed

and the key for one axis. The CNC moves the axis at fast feedrate.

2.4.2 INCREMENTAL JOG

Place the left-hand switch in one of the positions

Incremental movement must be done axis to axis. To do this press the JOG key for the direction of
the axis to be moved.

Each time a key is pressed, the corresponding axis moves the amount set by the switch. This
movement effects the «F» feedrate selected.

2.4 Jogging the axes

2.4.3 Jogging with an electronic handwheel

2.4.3 JOGGING WITH AN ELECTRONIC HANDWHEEL

The various handwheel configurations are:

General handwheel It can be used to jog any axis one by one.

Select the axis and turn the handwheel to move it.

Individual handwheel: It replaces the mechanical handwheels.

Up to 3 handwheels can be used (one per axis).
It only moves the axis it is associated with.

To move any of them, turn the switch to any of the handwheel positions.

Positions 1, 10 and 100 indicate the multiplying
factor being applied besides the internal x4 to
the feedback pulses supplied by the electronic
handwheel.
For example, if the manufacturer has set a
distance of 0.100 mm or 0.0100 inches per
handwheel turn, thus:

TC work mode

Switch position Distance per turn

1 0.100 mm or 0.0100 inch

10 1.000 mm or 0.1000 inch

100 10.000 mm or 1.0000 inch

Warning:

When operating with individual handwheels and depending on how fast the handwheel is
turned and on the selected handwheel switch position, the CNC might be demanded to
move the axis faster than the maximum permitted. In that case, the CNC will move the axis
the indicated distance but it will limit the axis speed to that maximum value.

There are 3 operating modes with handwheels:
Standard handwheel:

With the general handwheel, select the axis to be moved and turn the
handwheel.
With individual handwheels, turn the handwheel associated with the axis to be
moved.

Path handwheel: For chamfering and rounding corners.

2 axes are moved along a selected path (chamfer or rounding) by moving a
single handwheel.
This feature must be activated via PLC.
The general handwheel is assumed as the "path handwheel" or the individual
handwheel associated with the Z axis.

Feed handwheel To control the feedrate of the machine.

Chapter 2 - page 10

This feature must be activated via PLC.

2.4.3.1 STANDARD HANDWHEEL MODE

With the general handwheel proceed as follows:

1.- Select the axis to be jogged.
Press one of the JOG keys of the axis to be jogged. The selected axis will be highlighted.

When using a FAGOR handwheel with an axis selector button, the axis may be selected as
follows:

Push the button on the back of the handwheel. The CNC select the first axis and it highlights it.
When pressing the button again, the CNC selects the next axis and so on in a rotary fashion.
To deselect the axis, hold the button pressed for more than 2 seconds.

2.- Jog the axis
Once the axis has been selected, it will move as the handwheel is being turned and in the direction

indicated by it.

2.4 Jogging the axes

2.4.3 Jogging with an electronic handwheel

With individual handwheels:

Each axis will move as the corresponding handwheel is being turned according to the switch position
and in the direction indicated by it.

With several simultaneous handwheels:

The machine may have a general handwheel and up to 3 individual handwheels associated with each
axis.
The individual handwheels have priority over the general handwheel. So, if an individual handwheel
is moving, the general handwheel will be ignored.

2.4.3.2 PATH HANDWHEEL MODE

With this feature, it is possible to jog two axes at the same time along a linear path (chamfer) or circular
path (rounding) with a single handwheel.

The CNC assumes as the path handwheel the general handwheel or, when this one is missing, the one
associated with the Z axis.

This feature must be handled by the manufacturer of the machine.
While in handwheel mode and selecting the “path handwheel”, the CNC shows the following data:

When choosing a linear jog (upper drawing) , the angle of the path must be indicated and when
choosing a circular jog (lower drawing), the arc center coordinates must be indicated in radius.

To define these variables, press the [F] and, then, one of these keys:

Example: The [O2] key is used to activate or deactivate the "path handwheel" mode and the [O3] key

to indicate the type of movement.

DFU B29 R561 = CPL M5054 Activate / deactivate the "path handwheel" mode
DFU B31 R561 = CPL M5053 Selects the type of movement, along a straight line or an arc

2.4.5 Master Handwheel

2.4.3.3 FEED HANDWHEEL MODE

Usually, when making a part for the first time, the machine feedrate is controlled by means of the
feedrate override switch.

From this version on, it is also possible to use the machine handwheels to control that feedrate. This
way, the machining feedrate will depend on how fast the handwheel is turned.

To do this, proceed as follows:

Inhibit all the feedrate override switch positions from the PLC.
Detect how far the handwheel is turned (reading of pulses received)
Set the corresponding feedrate from the PLC depending on the pulses received from the
handwheel.

The following CNC variables return the number of pulses the handwheel has turned.

HANPF shows the number of pulses of the 1st handwheel.
HANPS shows the number of pulses of the 2nd handwheel.
HANPT shows the number of pulses of the 3rd handwheel.
HANPFO shows the number of pulses of the 4th handwheel.

To use this feature, the handwheel must be associated with one of the axes of the machine. General

machine parameters “AXIS1....8” or “HANDWHE1....4” set with values: “21....29”

Example: The machine has a button to activate and deactivate this feature (feed handwheel) and the

feedrate control is carried out with the second handwheel.

If the program is in execution ....................OPMODA bit 0 = 1

Therefore (IF ((CYCEXE NE 0) AND (OPMODA AND $1) EQ 1) there is movement.
The subroutine associated with the tools can contain the following information:

(SUB 55)

(P100 = NBTOOL) ; Assigns the No. of tool requested to P100
(P101 = MS3) ; If spindle clockwise P101=1

2.5.1 Variable tool change point

TC work mode

2.5.1.1 VARIABLE TOOL CHANGE POINT

If the manufacturer wishes the user can be allowed to define the tool change point at all times. This
feature logically depends on the type of machine and type of changer.

This feature allows the tool change to be made beside the part, thus avoiding movements to a change
point farther away from the same.

To allow this:

Define text 47 of the program 999997 for the CNC to request the coordinates on X and Z of the
change point.
For example: ;47 $CHANGE POSITION

These coordinates should always refer to machine reference zero (home), for the zero offsets not
to affect the tool change point.

For this reason, the CNC can display, along with coordinates X, Z and in small characters, the
coordinates for the axes referring to home.

For the CNC to show the coordinates of the axes referring to home text 33 of program 999997
has to be defined. For example: ;33 $REFERENCE ZERO (HOME)

Since the tool change point can be modified by the operator at any time, the subroutine associated
with the tools must take these values into account.

Arithmetical parameters P290 and P291 contain the values set by the operator as change position on
X, Z.

Arithmetical parameter P290

Change position on X

Arithmetical parameter P291

Change position on Z

In subroutine 55 of the previous section, the line fixing the movement to the change point must be
modified:

Where it says: G0 G53 XP??? ZP??? ; Movement to the change point.
It should say: G0 G53 XP290 ZP291 ; Movement to the change point defined by the user.

Define the coordinates of the change point (X, Z)

Press to select the "T" . Then press key for the relevant axis or:

After moving over the coordinates for the axis to be defined, one can:

a) Enter the value manually. Key in the value required and press

b) Assign the present position of the machine.

Move the axis, by means of the handwheel or the JOG keys, up to the point required.
Press . The CNC assigns said coordinate to the field selected.

When the machine uses a live tool, the following considerations must be born in mind:

Set one of the general machine parameters P0 through P9 to "13"
The location code (shape) of the live tool must be "10", "20" or "30".
It is up to the PLC to manage the keys for the live tool.

Every time one of these keys is pressed, the CNC updates the corresponding register bit.

Bit 7 of Register 561 (B7 R561) indicates the status of the key.

Bit 3 of Register 562 (B3 R562) indicates the status of the key.

Bit 5 of the Register 562 (B5 R562) indicates the status of the key

Here is an example of the section of the PLC program in charge of managing the live tool:

( ) = CNCRD (TOOL, R101, M1)

Assigns the number of the active tool to register R101.

= CNCRD (TOF R101, R102, M1)

Assigns the location code (shape) of the active tool to register R102.

2.6.2 CONSTANT SURFACE SPEED

In Constant surface speed mode the user sets the tangential speed that there must be at all times
between the tool tip and the part.

The spindle revolutions therefore depend on the position taken by the tool tip with respect to the
turning axis. If the tool tip moves away from the turning axis, the spindle revolutions thus go down,
and if it gets closer, they go up.

When Constant Surface Speed is selected the CNC displays the following information.

1.- Actual spindle speed in rpm.

2.6.2.1 OPERATING AT CONSTANT SURFACE SPEED (CSS)

When Constant Surface Speed operating mode is selected (CSS), the CNC assumes the spindle range
selected at present.

In this operating mode, when a new constant surface speed is selected, the following cases may arise:

a) The spindle is stopped

The CNC selects the new speed but does not apply this until the spindle moves.

b) The spindle is started

The CNC, depending on the position of the axis, calculates and makes the spindle turn at the
corresponding rpm. speed for the Constant Surface Speed to be as defined.

As the axes move, when working at Constant Surface Speed, the following cases may arise:

a) The spindle is started

The CNC moves the axes to the F programmed.
As the X axis is moved, the CNC makes the spindle speed (rpm.) match to maintain the constant

surface speed selected.
If the tool tip moves away from the turning axis the spindle revolutions therefore go down, and

if it gets nearer, they go up.
The CNC limits the spindle revolutions to the maximum speed set «SMAX».

b) The spindle is stopped but a spindle speed S is selected

The CNC calculates, in millimeters/minute, the feedrate corresponding to the last programmed
"S" and moves the axis.

For example, if «F 2.000» and «CSS 500»:

F (mm/min) = F (mm/min.) x S (rev/min) = 2 x 500 = 1000 mm/min
The axis moves at a feedrate of 1000 millimeters/minute

c) The spindle is stationary and there is no spindle speed S selected.

If feedrate F has value 0, the CNC moves the axes at fast feedrate.

If feedrate F has any other value, the axes will only be able to be moved if key is pressed
and the key for one axis. The CNC moves the axis at fast feedrate.

2.7 CONTROL OF EXTERNAL DEVICES

The CNC allows up to 6 external devices to be activated and deactivated from the keyboard. One of
these is the cooling fluid.

The activation and deactivation of the devices must be carried out by the machine manufacturer by
means of the PLC program.

The CNC will inform the PLC of the status of each one of the keys. The relevant Register bit will have
value 1 when the key is pressed and value 0 when this is not pressed.

The Register bit for each one of the keys is as follows:

The status of the light for each one of these keys must be controlled by the machine manufacturer
by means of the PLC program, with the TCLED* input variables shown in the figure being available
for this purpose.

Examples:

Control of the coolant: DFU B28R561 = CPL TCLED1

= CPL O33

Control of the tail-stock (O1). To activate or deactivate the tail-stock a number of conditions must

be satisfied such as spindle stopped, ....
