INSTALLATION MANUAL

Ref. 9707 (in)

ABOUT THE INFORMATION IN THIS MANUAL

This manual is addressed to the machine manufacturer.
It includes the necessary information for new users as well as advanced subjects for

those who are already familiar with the 8025 CNC.
It may not be necessary to read this whole manual. Consult the list of "New Features

and Modifications" and the appendix related to the machine parameters. Practically
all of them are cross referenced indicating the chapter and section of the manual
where they are described.

This manual explains all the functions of the 8025 CNC family. Consult the
Comparison Table for the models in order to find the specific ones offered by your
CNC.

To install the CNC onto your machine, we suggest that you consult the appendix
regarding the enclosures required to mount the CNC as well as chapter 1 (CNC
configuration) which indicates the CNC dimensions and details the pin-out of its
connectors.

If your CNC has an integrated PLC (PLCI), the I/O pin-out is different. Therefore,
the PLCI manual must also be consulted.

Chapter 2 (Power and Machine Interface) shows how to connect the CNC to A.C.
power (Mains) and to the electrical cabinet.

To adapt the CNC to the machine, set the CNC machine parameters. Consult chapters
3, 4 and 5 as well as the appendix concerning machine parameters.

There are 2 appendices; one where the parameters are ordered by subject and the
other one where the parameters are in numerical order.

Both appendices offer cross references indicating the section of the manual describing
each parameter.

When explaining each parameter in detail, chapters 3, 4 and 5, they sometimes refer
to chapter 6 (Concepts) where some of them are dealt with in further detail indicating
how to perform various adjustments of the CNC-machine interface.

Once all machine parameters are set, we suggest that you write their settings down
on the charts provided for this purpose in the appendix on "Machine Parameter Setting
Chart".

There is also an appendix on error codes which indicates some of the probable reasons
which could cause each one of them.

Also, if you wish this CNC to communicate with other FAGOR products, you must
use the Fagor Local Area Network (LAN). To do that, refer to the manual on FAGOR
LAN.

Notes

: The information described in this manual may be subject to variations due

to technical modifications.

SUGGESTIONS FOR THE RS232C INTERFACE

* Connect/disconnect peripheral.

The CNC must be powered off when connecting or disconnecting
any peripheral through this connector.

* Cable length. EIA RS232C standards specify that the capacitance of the cable

must not exceed 2500pF; therefore, since average cables have a capacitance between
130pF and 170pF per meter, the maximum length of the cable should not be greater
than 15m (49ft).

For greater distances, it is suggested to intercalate RS232C-to-RS422A signal
converters (and vice-versa). Contact the corresponding distributor.

Shielded cable with twisted-pair wires should be used to avoid communication
interference when using long cables.

Use shielded 7-conductor cable of 7*0.14mm² section.

* Transmission speed (baudrate). The baudrate normally used with peripherals is

9600 baud.
All unused wires should be grounded to avoid erroneous control and data signals.

* Ground connection. It is suggested to reference all control and data signals to the

same ground cable (pin 7 GND) thus, avoiding reference points at different voltages
especially in long cables.

RECOMMENDED CONNECTIONS FOR THE RS232C INTERFACE
* Complete connection

* Simplified connection

To be used when the peripheral or the computer meets one of the following
requirements:

- It does not have the RTS signal.

- It is connected via DNC.

- The receiver can receive data at the selected baudrate.

Nevertheless, it is suggested to refer to the technical manuals of the peripheral
equipment in case there should be any discrepancy.

1.3.6.1 INPUTS OF CONNECTOR I/O 1

X AXIS HOME SWITCH Pin 10

This INPUT must be high (24V) as long as the machine reference switch for the
X axis is pressed.

"C" OR 3rd AXIS HOME SWITCH Pin 11

This INPUT must be high (24V) as long as the machine reference switch for the
"C" or 3rd axis is pressed.

Z AXIS HOME SWITCH Pin 12

This INPUT must be high (24V) as long as the machine reference switch for the
Z axis is pressed.

4th AXIS HOME SWITCH / Activate the emergency subroutine Pin 13

When the machine has a 4th axis, P614(1)=1, this input corresponds to the home
switch for this axis. This input must be high (24V) as long as the machine reference
switch for the 4th axis is pressed.

When the machine does not have a 4th axis, P614(1)=0, and an emergency
subroutine has been programmed, P716<>0, the CNC will activate such subroutine
every time this input is set low (0V).

EMERGENCY STOP Pin 14

This INPUT must be normally high (24V).
When set low (0V), the CNC deactivates the axis enables and analog voltages, it

interrupts the part program execution and it displays ERROR 64 on the CRT.
It does not imply an emergency output (pin 5 of this connector).

CONNECTOR I/O1

(inputs)

FEED HOLD / TRANSFER INHIBIT / M-DONE Pin 15

This INPUT must be normally high (24V) and its meaning depends on the type
of block or function being executed at the time.

* If while moving the axes this signal (FEED-HOLD) is set low (0V), the CNC

maintains the spindle turning and stops the axes bringing their analog voltages
to 0V while maintaining their enables active.

When this input is brought back high (24V), the axes will resume their
movements.

* If while executing a motionless block this signal (TRANSFER INHIBIT) is set

low (0V), the CNC interrupts the program execution at the end of the block
currently in execution.

When this signal is brought back high, the CNC resumes program execution.

* The "M-DONE" signal is used when machine parameter "P602(7)" is set

to "1".
The CNC waits for the electrical cabinet to execute the requested

miscellaneous M function. In other words, it waits for the "M-done" input
to be set high (24V).

STOP/ Activate the emergency subroutine Pin 16

This INPUT must be normally high (24V) and its meaning depends on the the
system configuration.

* If the machine has a 4th axis, "P614(1)=1", and there is an emergency subroutine

(P716<>0), the CNC will activate the emergency subroutine whose number is
indicated by "P716" every time this input is set low.

* If the machine has neither a 4th axis, "P614(1)=0", nor an emergency subroutine

(P716=0), the CNC considers this input as (Cycle Stop) and acts as follows:
When this input is set low (0V), the CNC interrupts the program execution

just as if the key were pressed at the OPERATOR PANEL.
To resume program execution, it is necessary to bring this input back high

(24V) and press the key at the OPERATOR PANEL.

START Pin 17

This INPUT must be normally low (0V) and its meaning depends on the type of
operation selected.

While inactive, this input must be connected to 0V through a 10KOhm resistor.

When an up-flank (leading edge or low-to-high transition) of this signal (START)
is detected, the CNC considers that the external CYCLE START key is pressed
and it behaves as if the key were pressed at the OPERATOR PANEL.

However, to disable the key of the OPERATOR PANEL in order to only
use this input, set machine parameter P601(5) to "1".

BLOCK SKIP (Conditional input) Pin 18

Every time the CNC executes the miscellaneous function M01 (conditional stop),
it analyzes the status of this input. If high (24V), the CNC will interrupt the execution
of the program.

By the same token, every time the CNC must execute a conditional block, it will
analyze the status of this input and it will execute the block if this input is high
(24V).

DRO (DRO mode) Pin 19

If this input is set high (24V) while in the JOG mode, the CNC acts as a DRO.

Outputs M15 / Spindle lock / "C" axis Enable Pin 22

This OUTPUT provides the value of bit 15 of the decoded M table corresponding
to the selected M function.

When the spindle is working in closed loop (M19), this output is used as the spindle
lock. That is, it will be set to "0" when the spindle has to move and it will return
to "1" when the spindle has reached its programmed position (within the in-position
or dead-band zone).

When the machine has a 3rd axis, "P612(1)=1" working as a "C" axis, "P613(5)=1",
this output will be used as "C" axis Enable.

Care must be taken, when having this option, not to use the bit of the decoded M
table corresponding to this output M15 since the CNC will activate it in both cases.

Outputs M14 / G00 Pin 23

This OUTPUT provides the value of bit 14 of the decoded M table corresponding
to the selected M function.

If machine parameter P604(3) is set to "1" so the CNC provides the status of the
G00 signal, this OUTPUT will be set high (24V) whenever the CNC is executing
a rapid positioning move (G00).

If machine parameter "P609(6)=1", this OUTPUT is set high whenever the turret
turns in the positive direction.

For example, if a 12-tool turret is used and the current tool is number 2, the value
of this output will depend on the next tool being selected:

* When selecting tool 4 (positive direction 2, 3, 4), this output will be set high.
* When selecting tool 10 (negative direction: 2, 1, 12, 11, 10).

This OUTPUT provides the value of bit 12 of the decoded M table corresponding
to the selected M function.

When the machine has a 3rd axis "P612(1)=1", this OUTPUT is used as the 3rd

Atention:

Power switch

This power switch must be mounted in such a way that it is esaily
accessed and at a distance between 0.7 meters (27.5 inches) and 1.7
meters (5.5 ft) off the floor.

Intall this unit in the proper place

It is recommended to install the CNC away from coolants, chemical
products, possible blows etc. which could damage it.

2.1 POWER INTERFACE

The rear of the 8025 CNC has a three-prong connector for AC and ground connection.
This connection must be done through an independent shielded 110VA transformer

with an AC output voltage between 100V and 240V +10% -15%.
The power outlet to connect the equipment must be near it and easily accessible.
In case of overload or overvoltage, it is recommended to wait for 3 minutes before

powering the unit back up in order to prevent any possible damage to the power
supply.

2.1.1 INTERNAL POWER SUPPLY

Inside the 8025 CNC there is a power supply providing the required voltages.
Besides the 2 outside AC power fuses (one per line), it has a 5 Amp. fuse inside to

protect it against overcurrent.

2.2 MACHINE INTERFACE

2.2.1 GENERAL CONSIDERATIONS

The machine tool must have decoupled all those elements capable of generating
interference (relay coils, contactors, motors, etc.).

* D.C. Relay coils.

Diode type 1N4000.

* A.C. relay coils

RC connected as close as possible to the coils. Their approximate values should
be:

R 220 Ohms/1W
C 0,2 µF/600V

* A.C. motors.

RC connected between phases with values:

R 300 Ohms/6W
C 0,47µF/600V

Ground connection.

It is imperative to carry out a proper ground connection in order to achieve:
* Protection of anybody against electrical shocks caused by a malfunction.
* Protection of the electronic equipment against interference generated by the

proper machine or by other electronic equipment near by which could cause
erratic equipment behavior.

Therefore, it is crucial to install one or two ground points where the above
mentioned elements must be connected.

Use large section cables for this purpose in order to obtain low impedance and
efficiently avoid any interference. This way, all parts of the installation will have
the same voltage reference.

Even when a proper ground connection reduces the effects of electrical
interference (noise), the signal cables require additional protection.
This is generally achieved by using twisted-pair cables which are also covered
with anti-static shielding mesh-wire. This shield must be connected to a specific
point avoiding ground loops that could cause undesired effects. This connection
is usually done at one of the CNC's ground points.

POWER AND MACHINE INTERFACE

Section:Chapter: 2

MACHINE INTERFACE

Each element of the machine-tool/CNC interface must be connected to ground
via the established main points. These points will be conveniently set close to
the machine-tool and properly connected to the general ground (of the building).

When a second point is necessary, it is recommended to join both points with a
cable whose section is not smaller than 8 mm².

Verify that the impedance between the central point of each connector housing
and the main ground point is less than 1 Ohm.

DIGITAL INPUTS/OUTPUTS

2.2.4 ANALOG OUTPUTS.

The CNC has 6 analog outputs which could be used to command servo drives, spindle
drives and other devices.

The electrical characteristics of these outputs are:

Analog voltage range: ±10V.
Minimum impedance of the connected drive: 10 KOhm.
Maximum cable length without shield: 75 mm.

It is highly recommended to use the shielded cable connecting the shield to the
corresponding pin of the connector.

Atention:

It is recommended to adjust the servo drives so their maximum feedrate
(G00) is obtained at ±9.5 V.

2.2.5 FEEDBACK INPUTS

The feedback inputs are used to receive sine-wave, single-ended and double-ended
square-wave signals coming from linear or rotary transducers (encoders).

Connector A1 is used for the X axis feedback signals and it accepts sine-wave and
double-ended (differential) square-wave signals.

Connector A2 is used for the feedback signals from the 4th axis or the synchronized
tool and it accepts sine-wave and double-ended (differential) square-wave signals.

Connector A3 is used for the Z axis feedback signals and it accepts sine-wave and
double-ended (differential) square-wave signals.

Connector A4 is used for the feedback signals from the 3rd or "C" axis and it accepts
sine-wave and double-ended (differential) square-wave signals.

Connector A5 is used for the spindle feedback signals and it accepts double-ended
(differential) square-wave signals.

Connector A6 is used for the feedback signals from the probe and the electronic
handwheel or the synchronized tool. It accepts single-ended (not differential) square­wave signals.

The electrical characteristics of these inputs are:
Sine-wave signals Supply voltage ±5V.±5%

Maximum counting frequency 25KHz.

Square-wave signals Supply voltage ±5V.±5%

Maximum counting frequency 200KHz.

It is recommended to use shielded cables for their connection connecting the shield
to the corresponding pin of the connector.

2.3 SET-UP

2.3.1 GENERAL CONSIDERATIONS

Inspect the whole electrical cabinet verifying the ground connections BEFORE
powering it up.

This ground connection must be done at a single machine point (Main Ground Point)
and all other ground points must be connected to this point.

Verify that the 24V external power supply used for the digital inputs and outputs is
REGULATED and that its 0V are connected to the Main Ground Point.

Verify the connection of the feedback system cables to the CNC.
DO NOT connect or disconnect these cables to/from the CNC when the CNC is on.
Look for short-circuits in all connectors (inputs, outputs, axes, feedback, etc.) BEFORE

supplying power to them.

2.3.2 PRECAUTIONS

It is recommended to reduce the axis travel installing the limit switches closer to
each other or detaching the motor from the axis until they are under control.

Verify that there is no power going from the servo drives to the motors.
Verify that the connectors for the digital inputs and outputs are disconnected.
Verify that the feedback dip-switches for each axis are set according to the type of

feedback signal being used.
Verify that the E-STOP button is pressed.

It is possible to have several outputs active at the same time providing 24V at
their corresponding pins.

Once the INPUT/OUTPUT test is completed, disconnect the electrical cabinet and,
then, connect the input/output connectors as well as the feedback systems of the
axes to the CNC.

Then, connect the electrical cabinet and the CNC to AC power and activate the servo
drives.

2.4 EMERGENCY INPUT/OUTPUT CONNECTION

The Emergency Input of the CNC is called EMERGENCY STOP (E-STOP) and
corresponds to pin 14 of connector I/O1. This input must normally have 24V DC.

The CNC processes this signal directly, therefore, whenever these 24V disappear, it
will issue EXTERNAL EMERGENCY ERROR (Error 64), it will deactivate the
axes enables and cancel the analog voltages for all the axes and the spindle.
It does NOT imply the emergency output (pin5).

The electrical cabinet interface must take into account all the external elements that
could cause this error.

For example, some of these elements may be:
* The E-Stop button has been pressed.
* An axis travel limit switch has been pressed.
* An axis servo drive is not ready.

On the other hand, whenever a CNC detects an internal emergency error, it will
activate the EMERGENCY OUTPUT at pin 5 of connector I/O1.

This output will be normally high or low depending on the setting of machine parameter
P605(8).

There are some of the internal causes that can activate this output:
* An excessive axis following error has occurred.
* An axis feedback error has occurred.
* There is erroneous data on the machine parameter table.

3. MACHINE PARAMETERS

Atention:

All unused machine parameters must be set to "0" to guarantee the proper
functioning of the 8025T CNC.

It is recommended to save the machine parameters of the CNC at a
peripheral device or computer in order to be able to recover them after
their accidental loss.

Please note that some of the machine parameters mentioned here are
described in greater detail in the chapter on "CONCEPTS" in this manual.

3.1 INTRODUCTION

On power-up, the CNC performs a system hardware test. When completed, it displays
the model name and the message: "GENERAL TEST PASSED" when successful
and the corresponding error message if otherwise.

In order for the machine-tool to be able to properly execute the programmed
instructions and recognize the interconnected elements, the CNC must "know" the
specific data for the machine such as feedrates, acceleration ramps, feedback devices,
etc.

This data is determined by the machine manufacturer and may be input via keyboard
or via the RS232C serial line by setting the machine parameters.

To lock or unlock access to machine parameters, decoded "M" function table and to
the leadscrew error compensation tables, proceed as follows:

* Press the [OP MODE] key.
* Press [6] to select the Editing mode.
* Press the softkey for [LOCK/UNLOCK]. The screen will show the word: "CODE:"

(password).

* Key in "PKAI1" and press [ENTER] to lock the access or key in "PKAI0" and

press [ENTER] to unlock the access.

When access to machine parameters is locked, only
communications via RS232C may be changed.

CAUTION when using a CNC with an integrated PLC (CNC+PLCI)

When using this access locking code, the machine parameters, the decoded "M"
function table and the leadscrew error compensation tables are stored in EEPROM
memory.

When using the access unlocking code, it recovers these previously stored tables
from the EEPROM memory.

Therefore, one must be careful and lock these tables before

unlocking them.

Otherwise, the factory set values or other prelocked values, may be restored overwriting
the ones the manufacturer entered but did not lock.

To enter the machine parameter values via the keyboard, press the following keystroke
sequence:

3.2 OPERATION WITH PARAMETER TABLES

Once the machine parameter table has been selected, the operator may view the
following or previous pages by means of the up and down arrow keys.

To view a particular parameter, key in the desired parameter number and press
[RECALL]. The CNC will display the page corresponding to that parameter.

To EDIT a parameter, key in the desired number, press [=] and key in the value to
be assigned to that parameter.

Depending on the type of machine parameter selected, it could be assigned one of
the following types of values:

* A number P111 = 30000
* A group of 8 bits P602 = 00001111
* A character P105 = Y

Once the value of the parameter has been keyed in, press [ENTER] so it is entered
on the table.

If when pressing [=], the parameter being edited disappears from the screen, it means
that the machine parameters are locked, therefore protected against modifications.

Once all the desired parameters have been set, either press [RESET] or power the
CNC off and back on so the CNC assumes the new values.

Every time a parameter bit is mentioned while describing the different machine
parameters, refer to this nomenclature:

P602 = 0 0 00 1 11 1

It indicates the number of the program to be protected against being read or
edited.

It is given by an integer between 0 and 9999. If "0" is assigned, the CNC will
interpret that no program is to be protected.

It is recommended to use this parameter to protect a program which contains the
subroutines which should remain unseen by the operator.

The protected program will not be listed on the program directory and when
requesting a subroutine defined in this program, the CNC will show the text:
“P????”.

P612(1), P614(1) The machine has a 3rd, 4th axis

0 = The machine does not have a 3rd or a 4th axis.
1 = The machine has a 3rd or a 4th axis.

P613(5) The 3rd axis is the "C" axis

P613(3), P615(3) The 3rd, 4th axis as a DRO axis

Indicates whether the CNC treats the corresponding axis as a normal axis or as
DRO axis.

0 = Normal axis.
1 = DRO axis.

P613(1), P615(1) The 3rd, 4th axis is rotary

It indicates whether the axis is linear or rotary.
The position of a rotary axis is shown in degrees. Therefore, it is not affected by

the mm/inch unit change. It does not admit tool radius compensation or circular

interpolation.

0 = Linear axis.
1 = Rotary axis.

P613(2), P615(2) The 3rd, 4th axis is rotary ROLLOVER

This parameter is used when the axis is set as rotary, “P613(1)=1, P615(1)=1”
and the count is to roll over to 0° when reaching 360°.

0 = It is not ROLLOVER.
1 = It is ROLLOVER.

P613(6), P615(5) The 3rd, 4th axis is rotary rollover via shortest path

This parameter is used when the axis is set as rotary rollover and the programmed
movements are to be carried out via the shortest path.

0 = It is not positioned via the shortest path.
1 = It is positioned via the shortest path.

P616(8) Connector A6 shared by the handwheel and the synchronized tool

This parameter must be set to "1" when the machine has a 4th axis, synchronized
tool and electronic handwheel (all three).

A2 must be the feedback connector for the 4th axis, A6 must then be shared by
the synchronized tool and the electronic handwheel.

Pin 21 of connector I/O1 (output indicating JOG mode selected) may be used to
switch both feedbacks (synchronized tool and electronic handwheel) since the
electronic handwheel can only be used in JOG mode.

0 = Connector A6 is not shared.

FOR AXES

CONFIGURATION

3.3.2 I/O PARAMETERS

P604(4) Normal status of the Emergency output (pin 5 connector I/O 1)

It determines whether the emergency output is normally low or high.

0 = Normally low (0V). An emergency situation will set this output high

(24V).

1 = Normally high (24V). An emergency situation will set this output low

(0V).

P609(6) Pin 24 of connector I/O 2 indicates turret rotating direction

It determines whether pin 24 of connector I/O 2 is used to indicate the turrret
rotating direction or not.

0 = It is output 13 of the decoded M functions.
1 = It is the output indicating the turret rotating direction and output 13 of

the decoded M functions.

If this machine parameter is set to "1", this OUTPUT is set high (24V) whenever
the turret turns in the positive direction.

For example, if a 12-tool turret is used and the current tool is number 2, the
value of this output will depend on the next tool being selected:

* When selecting tool 4 (positive direction 2, 3, 4), this output will be set high.
* When selecting tool 10 (negative direction: 2, 1, 12, 11, 10).
Care must be taken, when having one of these options, not to use the bit of the

decoded M table corresponding to this output M13 since the CNC will activate
it in both cases.

P604(3) G00 mode indicating output at pin 23 of connector I/O 2

It determines whether pin 23 of connector I/O 2 is used to indicate the G00 mode
or not.

0 = It is output 14 of the decoded M functions.
1 = It is the G00 output and output 14 of the decoded M functions.

This output will stay active (24V) while the CNC is performing a G00 move
(rapid traverse).

It must be borne in mind that the CNC uses the same pin to indicate both concepts
(G00 and M14 output). Therefore, if it is to be used as an indicator for G00, this
bit must not be used when setting decoded M functions.

P605(4) Pin 6 of connector I/O 1 as THREADING-ON or CYCLE-ON indicator

0 = This output will be active (24V) when a THREADING cycle is being

executed.

1 = This output will be active (24V) when a program block is being executed

(CYCLE ON) is being executed or when a "BEGIN-START", "END­START" type command is being executed.

P606(7) M function not output in BCD

When executing an M function which has been decoded at the M function table,
the CNC will activate and/or deactivate the corresponding outputs at connector
I/O 2.

This parameter determines whether or not besides activating the outputs set on
the table, the CNC also activates the BCD outputs: "MST01" thru "MST80" (pins
20 thru 27 of connector I/O 1) corresponding to that M function.

0 = The M function is also sent out in BCD.
1 = The M function is not sent out in BCD

P602(7) The CNC waits for a down flank (trailing edge) of the M-done signal.

It indicates whether it is necessary or not to wait for the down flank (change
from 24V to 0V) of the M-DONE signal (at pin 15 of connector I/O 1) in response
to an "S STROBE", "T STROBE" or "M STROBE" so the CNC resumes the
execution of such functions.

“P602(7)=0”

The CNC will send out to the electrical cabinet the BCD signals corresponding
to the M S or T code for a period of 200 milliseconds. Then, if the "M-DONE"
signal is low (0V), it will wait for it to be set high (24V) in order to consider
the M, S or T function done.

Page

MACHINE PARAMETERS

Section:Chapter: 3

I/O PARAMETERS

“P602(7)=1”

50 milliseconds after having sent the M, S or T BCD signals out to the electrical
cabinet, it sends out the corresponding "Strobe" signal.

Then and if the "M-DONE" is high (24V), it waits for it to be set low (0V).
Once the "M-DONE" signal is set low, the CNC maintains the "Strobe" signal

active for another 100 milliseconds.
After deactivating the Strobe signal, the M, S or T BCD signals are kept active

for another 50 milliseconds.
After that time and if the "M-DONE" signal is low, the CNC will wait until

it becomes high so it can consider the auxiliary function M, S or T completed.

P603(4), P603(3), P603(2), P603(1), P608(1)

Cancellation of feedback alarm for connectors: A1, A2, A3, A4 and A5

The CNC will issue a feedback alarm for an axis when its corresponding feedback
signals are not received properly.

This parameter indicates whether this alarm is to be active or cancelled.

0 = Alarm active.
1 = Alarm cancelled.

This parameter must be set to "1" when the feedback system installed uses
only three square-wave signals (A, B, Io).

5 = Resolution of 0.005 mm, 0.0005 inch
10= Resolution of 0.010 mm, 0.0010 inch

P602(4) Multiplying factor for the feedback signals from the handwheel

It indicates the x2 or x4 multiplying factor to be applied to the feedback signals
supplied by the handwheel.

0 = x4.
1 = x2.

Example:

If the handwheel is set as follows:

P602(1) = 0 Millimeters

3.3.4 TOUCH PROBE PARAMETERS

P606(6) Pulse type of the touch probe

It indicates whether the probe functions of the CNC are active high (positive
pulse) or low (negative pulse) with the probe signal received at connector A6.

0 = Negative pulse (0V.).
1 = Positive pulse (5V. or 24V.).

P710 M function associated with the probing movement (G75)

It indicates the M function that is executed when a probing move is carried out
(G75).

It is defined by an integer between 0 and 99. If set to "0", no miscellaneous M
function will be executed.

The CNC executes the selected M function before starting the execution of G75.
The selected M function may be used, for example, to activate an infrared-based

probe.

P806 Probing feedrate in JOG mode

It indicates the probing feedrate used when calibrating and loading the tool length
by means of a touch probe in JOG mode.

PROBE PARAMETERS

3.3.5 TOOL PARAMETERS

The section on "tools " in the chapter on "concepts" of this manual describes
how these parameters may be used.

P700 Number of tools

It is given by an integer between 0 and 32.

P730 Subroutine associated with the T function

It indicates the standard subroutine (not parametric) that will be executed when
the block in execution contains a T function. In other words, every time a tool
is selected in the part-program.

It is defined by an integer between 0 and 99. If set to "0", no subroutine will be
executed.

This way, it will be possible to define the corresponding standard subroutine to
select the desired tool.

Atention:

When associating a subroutine to the T function, the T function must be
the last programmed item on the block. Otherwise, the CNC will issue
the corresponding error code.

P617(2) The associated subroutine is executed before the T function

It determines whether the subroutine associated with the T function is executed
before or after the T function.

0 = It is executed after the T function.
1 = It is executed before the T function.

When the subroutine is executed before the T function, remember the following
considerations:

* The T function must be programmed alone in the block.
* If the T function is executed in the JOG or TEACH-IN modes, the CNC will

not execute the associated subroutine.

P604(5) The tool offset values are effective after executing M06

It indicates whether the tool offset is applied right after the T2.2 function is
executed or after M06 is executed.

0 = Tool offset effective after T2.2
1 = Tool offset effective after M06

For example: If every time a new tool is selected, the machine must make some
movements prior to the tool change; it is recommended to set this parameter to
"1" and program an M06 right after the tool change in the subroutine associated
to the T function.

MACHINE PARAMETERS

TOOL PARAMETERS

PageChapter: 3 Section:

P609(3) The theoretical position corresponds to the tool tip or tool base

It indicates whether the CNC ignores the tool dimensions or not when displaying
the theoretical position. That is, whether the displayed position corresponds to
the tool tip or to the tool base.

0 = The displayed theoretical position value corresponds to the tool tip.
1 = The displayed theoretical position value corresponds to the tool base.

When setting this parameter to "0", the CNC will update the displayed position
after the tool change showing the new position corresponding to the tip of the
new tool.

This way, if an incremental move (G91) is programmed after a tool change, the
target position will be referred to the tip of the new tool.

On the other hand, when setting this parameter to "1", the CNC will not update
the displayed position and if an incremental move (G91) is programmed after a
tool change, the target position will be referred to the last programmed position.

3.3.6 PARAMETERS RELATED TO THE EMERGENCY SUBROUTINE

P716 EMERGENCY subroutine

It indicates the number of the standard subroutine (not parametric) that will be
executed when activating the EMERGENCY SUBROUTINE input (pin 13 or16
of connector I/O1).

It is defined by an integer between 0 and 99. If set to "0", no emergency subroutine
will be executed.

P616(2) The Emergency subroutine executes M00

It indicates whether the CNC must execute an M00 after the Emergency subroutine
or not.

Function M00 interrupts program execution and is not output.

0 = M00 is executed.
1 = M00 is not executed.

P616(1) Coordinate assignment to arithmetic parameter in Emergency

subroutine

It indicates the coordinates to be assigned to an arithmetic parameter when
executing a "P0=X" type block in the emergency subroutine.

0 = It assigns the coordinates of the beginning point of the block interrupted

by the emergency.

1 = It assigns the coordinates of the point where the emergency input was

activated.

If at the beginning of the emergency subroutine we program the block: “P0=X
P2=Z”, and after performing all the emergency operations we program, inside
the emergency subroutine, a block with movement to point "XP0 ZP2", the tool
will return to the point of program interruption or to the beginning point of the
interrupted block.

the settings of machine parameters P0, P1, P2 and P3.

P605(6)=0 Communication with a FAGOR Cassette reader reader/recorder.

The CNC ignores the setting of parameters P0, P1, P2 and P3 and
it uses the following internal setting for the FAGOR Cassette
reader/recorder:

Baudrate = 13,714 Baud
Number of data bits = 7 bits

* More than 30 seconds elapse without receiving a character while in the reception

mode.

* More than 3 incorrect acknowledgments or non-acknowledgments occur in a

row while in transmission mode.

This parameter can be used in order to be able to debug a user communications
program without the CNC aborting the communication.

jog key is pressed or it keeps moving until either the key or another JOG
key is pressed.

N = Continuous mode. The axis starts moving when its corresponding

JOG key is pressed and it stops when the key or any other
JOG key is pressed. When pressing the jog key for another axis,
this new axis will begin to move in the chosen direction until
or another JOG key is pressed.

P601(7) Recover initial conditions when returning to the standard work mode.

It determines whether or not the CNC must recover the initial conditions set by
machine parameters (spindle status, feedrates, etc.) every time the standard work
mode is accessed.

The standard work mode is accessed in the following cases:
* On CNC power-up, after pressing any key.
* When quitting the tool table.
* When quitting any of the auxiliary modes, general parameters, decoded M

functions, leadscrew compensation table, peripherals or the lock/unlock option.

0 = No, it does not recover the initial conditions.

P601(5) Inhibiting the START key.

It indicates whether the key from the front panel is ignored by the CNC
or not.

0 = It is not ignored. Not inhibited.
1 = It is ignored. Inhibited.

P619(6) Spindle inhibit via PLC.

To stop the spindle via PLC, it is possible to:
* Cancel (disable) the drive enable.

* Send the M05 code out to the CNC.
* Use the O43 signal of the PLCI or the M11 signal of the PLC64 to disable

or re-enable the Spindle.

This machine parameter, P619(6), indicates whether or not O43 (at the PLCI) or
M11 (at the PLC64) are used to enable or disable the spindle.

0 = They are not used.
1 = They are used.

When the CNC receives the spindle inhibiting signal, (O43 =1) or (M11=1), it
outputs an analog voltage of 0V; but it does not change the current spindle
conditions such as selected gear, rotating direction, etc.

When the spindle is re-enabled, (O43 =0) or (M11=0), the CNC outputs the
corresponding spindle analog voltage again.

P600(3) Maximum % value of the Feedrate Override Switch applied by the

CNC

It determines the maximum % value to be selected with The Feedrate Override
Switch.

zero offset.

0 = G59 as normal zero offset.
1 = G59 as additive zero offset.

When setting this parameter to "1", additive, every time a G54-G58 type function
is executed, the CNC applies on to each axis a zero offset equal to the sum of the
programmed offset value plus that of G59.

P609(5) Arithmetic parameters P150 through P254 as read-only

It indicates whether arithmetic parameters P150 through P254 are read/write or
read-only when the machine parameters are locked (code: PKAI1).

0 = Always read/write.

P621(4) Synchronization with independent axis

It indicates whether the independent axis (G65) is synchronized or not with the
next block.

0 = It is not synchronized.
1 = It is synchronized.

For example, When programming: N100 G65 X32

N110 G01 Z100
N120 G01 Z20

Depending on the setting of this machine parameter, the CNC will behave as
follows:

P621(4)=0 The CNC starts executing block N100 and, then, block N110. Once

block N110 is in position, the CNC continues executing the program
regardless of whether Block N100 has reached position or not.

P621(4)=1 The CNC starts executing block N100 and, then, block N110. Once

block N110 is in position, the CNC waits until block N100 reaches
position before going on to execute the rest of the program.

with sine-wave feedback

When using sine-wave feedback signals, the CNC considers these parameters as
well as P103, P203, P303, and P403 to set the axis resolution.

Possible values for P103, P203, P303, and P403 with P619(1), P619(2), P619(3),

P604(2), P604(1), P612(3), P614(3) Binary encoder on X, Z, 3rd, 4th axis

It indicates whether the corresponding axis has a BINARY encoder (1024/2048
lines per turn) or not.

0 = It is a binary encoder.
1 = It is not a binary encoder.

P604(7), P604(6), P612(4), P614(4) Equivalence of the binary encoder used

for the X, Z, 3rd and 4th axes.

These parameters are used when having binary rotary encoders (of 1024 or 2048
lines /rev.) and the desired resolution requires either 1000, 1250, 2000 or 2500
counts/rev.

These parameters are to be set when using a binary encoder (1024 or 2048 pulses)
in place of one with 1000 or 1250 lines to obtain the desired resolution.

By setting this parameter, the CNC will adapt the encoder pulse-count as follows:

0 = It will treat the 1024-count binary encoder as a 1250-count and the 2048-

count binary encoder as a 2500-count encoder.

1 = It will treat the 1024-count binary encoder as a 1000-count and the 2048-

count binary encoder as a 2000-count encoder.

To calculate the axis resolution (P103, P203, P303, P403, P503) use the equivalent
number of pulses selected here (1000, 1250, 2000, 2500).

The usefulness of the binary encoders is obvious since the same encoder can be
utilized on two different types of leadscrews (for example 4-pitch and 5-pitch)
without having to stock two different encoder models.

Leadscrew pitch 1/4 inch/turn

Encoder = = = 1250 pulses/turn

Multiplying factor x Resolution x4 x 0.0001 inch/pulse

Leadscrew pitch 1/5 inch/turn

4.2 MACHINE PARAMETERS FOR AXIS ANALOG OUTPUTS

The section on "Adjustment of the axes" in the chapter on "concepts" of this
manual describes how these parameters may be used.

P117, P317, P217, P417 Minimum analog output for the X, Z, 3rd and 4th
axes

It is given by an integer value between 1 and 255.

Value of 1 = 2.5 mV.
Value of 10 = 25.0 mV. (10 x 2.5)
Value of 255 = 637.5 mV. (255 x 2.5)

P104, P304, P204, P404 Delay between Enable and Analog output for the

X, Z, 3rd and 4th axes

They determine whether a 400 msec. delay must be applied from the time the
Enable signal is activated to the instant the analog output is generated.

N = There is no delay between the two signals
Y = There is a 400 msec. delay between the two signals.

These parameters are to be used when there is no continuous control of the axes.
therefore the 400 msec. delay could be used to deactivate possible axis holding
devices (holding brake and so forth).

P118, P318, P218, P418 In-position zone for the X, Z, 3rd and 4th axes (dead

band)

The In-position zone is the positioning tolerance area around the programmed
position (coordinate) where the CNC considers an axis to be in position.

This area is expressed in microns regardless of the selected work units.

Value range: 0 thru 255 microns.

P105, P305, P205, P405 Continuous control of the X, Z, 3rd and 4th axes

They determine whether there is a continuous control of the axis or not once it
has reached position. That is: whether the Enable signal remains on or not when
the axis is in position.

N = The Enable signal disappears.
Y = The Enable signal is maintained (Continuous control).

The CNC keeps the axes in position when set as continuously controlled axis.

P108, P308, P208, P408 Negative travel limit for the X, Z, 3rd and 4th axes

They determine the positive and negative travel limits for the axes. Each one
must indicate the distance from Machine Reference Zero to each travel limit.

Value ranges: ± 8388.607 millimeters or degrees

± 330.2599 inches.

If both limits are set with the same value (for example "0"), the axis will not be
able to move.

For safety reasons, it is only possible to move the axes up to 100 microns from
the travel limits set by these parameters.

movement.

4.4.1 LEADSCREW BACKLASH

P109, P309, P209, P409 Amount of leadscrew backlash for the X, Z, 3rd and

4th axes

When using linear scales, set this parameter to 0.
It is always expressed in microns regardless of the selected work units.

Defines the sign of the backlash compensation value set in parameters P109,
P209, P309 and P409.

0 = Positive sign.
1 = Negative sign.

P113, P313, P213, P413 Additional analog pulse for X, Z, 3rd and 4th axis

backlash

Additional 40msec. analog pulse to recover the possible backlash of the leadscrew
when reversing movement direction.

It is given by an integer between 0 and 255.

Value of 0 = No additional pulse being applied.
Value of 1 = 2.5 mV.
Value of 10 = 25.0 mV. (10 x 2.5)
Value of 255 = 637.5 mV. (255 x 2.5)

Every time the movement is reversed, the CNC will apply to this axis its
corresponding analog voltage plus the additional pulse indicated by this parameter.
This additional pulse will last for 40 milliseconds.

When using rotary encoders, set this parameter to "0".

4.4.2 LEADSCREW ERROR

There are 2 leadscrew compensation tables with 30 points each; one for the X axis
and another one for the Z axis.

For each point, it is required to define the position of the axis and the amount of
error at that point.

To access these tables, press the following keystroke sequence:

[OP MODE] Display of the various operating modes.
[9] Access to special modes.
[3] Access leadscrew error compensation tables.

The operator may view the following or previous pages by using the up and down
arrow keys.

To view a particular parameter, key in its number and press [RECALL]. The CNC
will show the page corresponding to that parameter.

To clear the table by setting all the parameters to 0, key in the following sequence:
[K] [J] [I] [ENTER].

Each parameter pair of this table represents:
Even parameter The position of the error point on the leadscrew. This position is

referred to Machine Reference Zero (home).
Value range: ±8388.607 millimeters

±330.2599 inches

Odd parameter The amount of leadscrew error at that point.

Value range: ±32.766 millimeters

±1.2900 inches

When defining the compensation points on the table, the following rules must be
observed:

* The even parameters are ordered according to their position along the axis. The

first pair of parameters (P0 or P60) must be set for the most negative (least positive)

point of the axis to be compensated.
* If all 30 points of the table are not required, set the unused ones to 0.
* For those sections outside the compensation area, the CNC will apply the

compensation defined for the nearest point.
* The Machine Reference Zero point (home) must be set with an error of 0.
* The maximum difference between the error values of two consecutive

compensation points must be within: ±0.127 mm (±0.0050 inches)
* The inclination of the error graph between two consecutive points cannot be

greater than 3%.
