ERRORS FOUND IN THE PROGRAMMING MANUAL (REF. 9701)

Page 64. Function G51.

When working in diameters, the "I" value in the table is in diameters and the value to be assigned to parameter
"I" in the G51 function must always be given in radius.

Section 12.4. (Chapter 12 page 133) Nesting levels.

The figure reads M02 ó M30
It should read: M02 or M30

ERRORS FOUND IN THE OPERATING MANUAL (REF. 9701)

Page 46. Last paragraphs.

It should say:

The CNC asks which is the source program number and which is the new program number, after keying each one
of them, press [ENTER].

If the number of the source program does not exist, or there is already a program in memory with the same number
as the new one or if there is not enough when copying the new program , the CNC will issue a message indicating
the cause.

ERRORS FOUNDS IN THE INSTALLATION MANUAL (REF. 9707)

Section 5.4 (chapter 5 page 7) Machine parameters for spindle control:

Parameter P606(3) is missing:

P606(3) Spindle counting direction

It sets the spindle counting direction. If correct, leave it as it is or change it if otherwise.
Possible values: "0" and "1".

MODIFICATIONS TO THE INSTALLATION MANUAL (REF. 9707)

Section 2.3.4 (chapter 2 page 9). Logic Outputs:

In the table, the following output is missing:

Output "C"
Row 1: (pin 3 I/O 1) M strobe
Row 2: (pin 5 I/O 2) output 3, decoded M function

Section 3.3.3 (chapter 3 page 11). P602(4). Another example:

Having a Fagor electronic handwheel (25 lines per turn) set as follows:

P602(1)=0 Millimeters P501=1 Resolution 0.001 mm. P602(4)=0 x4 Multiplication factor
Depending on the position of the MFO switch (Manual Feedrate Override), the selected axis will move:
Position 1 1 x 25 x 4 = 0.100 mm per turn
Position 10 10 x 25 x 4 = 1.000 mm per turn
Position 100 100 x 25 x 4 = 10.000 mm per turn

MODIFICATIONS TO THE LAN MANUAL (REF. 9701)

Section 2.2 (page 3). P616(7)

The first 2 paragraphs change. They should say:

If "P616(7)=0" the 8025 T CNC uses pin 15 of connector I/O1 as the input for the Feed-Hold, Transfer-Inhibit
and M-done signals as described in the Installation manual, chapter 1 section "Inputs of connector I/O 1"

If "P616(7)=1" the CNC behaves as follows:

* The Feed-Hold input will be "taken" .......

Version 7.1 (July 1996)

1. EXPANSION OF THE INTEGRATED PLC RESOURCES

1.1 INPUTS

1.1.1 TYPE OF FEEDRATE (G94/G95)

PLCI input I86 will show at all times the type of feedrate (F) selected a the CNC.

I86 = 0 G94. Feedrate in millimeters (inches) per minute.
I86 = 1 G95. Feedrate in millimeters (inches) per revolution.

1.1.2 TYPE OF CUTTING SPEED (G96/G97)

I87 = 0 G97. Constant tool center speed.
I87 = 1 G96. Constant cutting-edge speed

1.1.3 AXIS BEING HOMED (REFERENCED)

Input I88 indicates whether a home search is taking place and inputs I100, I101, I102, I103 and I104 indicates which
axis is being homed.

I88 Indicates whether any axis is being homed (0=No / 1=Yes)
I100 Indicates whether the X axis is being homed (0=No / 1=Yes)
I101 Indicates whether the 3rd axis is being homed (0=No / 1=Yes)
I102 Indicates whether the Z axis is being homed (0=No / 1=Yes)

1.1.4 AXIS MOVING DIRECTION

Inputs I42, I43, I44 and I45 will show, at all times, the moving direction of each axis.

I42 Indicates the moving direction of the X axis (0=Positive / 1=negative)
I43 Indicates the moving direction of the 3rd axis (0=Positive / 1=negative)
I44 Indicates the moving direction of the Z axis (0=Positive / 1=negative)
I45 Indicates the moving direction of the 4th axis (0=Positive / 1=negative)

1.2 OUTPUTS

1.2.1 ENABLING THE CYCLE-START KEY VIA PLCI

With this feature it is possible to set the treatment of the [CYCLE START] of the CNC via PLCI. Machine parameter
"P621(7)" indicates whether this feature is available or not.

P621(7) = 0 This feature is not available.
P621(7) = 1 This feature is available.

When using this feature, the way the CNC handles the [CYCLE START] key depends on the status of PLCI output O25
(CYCLE START ENABLE).

O25 = 0 The CNC ignores both the [CYCLE-START] key and the external [CYCLE-START] signal.
O25 = 1 The CNC takes into account both the [CYCLE-START] key and the external [CYCLE-START]
signal.

1.2.2 TRAVEL LIMITS SET VIA PLCI

With this feature, the travel limits of the axes may be set via PLCI. Machine parameter "P621(7)" indicates whether
this feature is available or not.

P621(7) = 0 This feature is not available.
P621(7) = 1 This feature is available.

To set the travel limits for each axis, use the following outputs:

O52 / O53 Positive / negative X axis limits
O54 / O55 Positive / negative 3rd axis limits
O56 / O57 Positive / negative Z axis limits
O58 / O59 Positive / negative 4th axis limits

When the PLCI activates one of this outputs while the axis is moving in the same direction, the CNC stops the axes and
the spindle and it displays an axis-travel-limit-overrun error.

1.2.3 DENYING ACCESS TO THE EDITOR MODE VIA PLCI

Machine parameter "P621(7)" indicates whether this feature is available or not.

P621(7) = 0 This feature is not available.
P621(7) = 1 This feature is available.

When using this feature, access to the editor mode at the CNC depends on the status of PLCI output O26, as well as
on the current conditions (protected memory, number of the program to be locked).

O26 = 0 Free access to the editor mode (it is protected by current conditions).
O26 = 1 Denied access to the editor mode.

1.2.4 SPINDLE CONTROLLED VIA CNC OR VIA PLCI

From this version on, the spindle analog output may be set either by the CNC or by the PLCI. Machine parameter
"P621(7)" indicates whether this feature is available or not.

P621(7) = 0 This feature is not available
P621(7) = 1 This feature is available

Setting the spindle analog output via PLCI

To do this, use the combination: M1956 - R156.
Register R156 sets the spindle analog output in units of 2.442 mV. (10 / 4095)

R156 = 0000 1111 1111 1111 (R1256=4095) = 10V.
R156 = 0001 1111 1111 1111 = -10V.
R156 = 0000 0000 0000 0001 (R1256=1) = 2.5 mV.
R156 = 0001 0000 0000 0001 = -2.5 mV.

In order for the CNC to assume the value allocated to register R156, one must activate mark M1956 as described
in the PLCI Manual (section 5.5.2. Writing internal CNC variables).

Spindle controlled either by the CNC or by the PLCI

The CNC may have two internal spindle analog outputs, that of the CNC itself and the one set by the PLCI.
Use PLCI output O27 to "tell" the CNC which one of them to output.

O27 = 0 Spindle analog output set by the CNC itself.
O27 = 1 Spindle analog output set by the PLCI (combination: M1956-R156).

1.3 READING INTERNAL CNC VARIABLES

From this version on, the PLCI and the PLC64 have access to more internal CNC information.
With the PLCI, there is no need to activate a mark to access this information. The CNC itself updates this information

at the beginning of each PLCI cycle scan.
With the PLC 64, the corresponding mark must be consulted every time a CNC variable is to be checked.
The CNC information now accessible is:

Real S in rpm (REG119 at the PLCI, M1919 at the PLC64)

Not to be mistaken with R112 which indicates the programmed Spindle speed (S).
It is given in rpm and in hexadecimal format. Example: S 2487 R119= 967

Number of the block in execution (REG120 at the PLCI, M1920 at the PLC64)

It is given in hexadecimal format. Example: N120 R120= 78

Code of the last key pressed (B0-7 REG121 at the PLCI, Not available at the PLC64)

Not to be mistaken with register R118 which also indicates the code corresponding to the last key pressed,

but—
When pressing a key, both registers have the same value; but the data in R121 is only kept there for one cycle

scan whereas R118 keeps its value until another key is pressed.

When pressing the same key several times, (for example: 1111):

R121 will show code "1" four times (once per cycle scan).
R118 will always show the same value, thus not being able to tell whether the "1" key has been pressed once
or more times.

The key codes are listed in the appendix of the PLCI manual.

- 5 -

Operating mode selected at the CNC (B8-11 REG121 at the PLCI, Not available at the PLC64)

Status of the miscellaneous "M" functions (REG122 at the PLCI, Not available at the PLC64)

The status of each one of these functions is given by a bit and will appear as a "1" when active and "0" when inactive.

2. 4TH AXIS NOW AVAILABLE ON 8025T MODELS

From this version on, this feature is now available on all these models:

CNC-8025T (not available until now) CNC-8025TG CNC-8025TS
CNC-8025TI(not available until now) CNC-8025TGI CNC-8025TSI

3. SPINDLE SPEED DISPLAY UNITS

Until now, the spindle speed was always displayed in rpm. From now on, the display units may be selected by means
of machine parameter "P621(6)".

P621(6) = 0 In rpm when operating in RPM and in m/min. (ft./min.) when at Constant Surface Speed.
P621(6) = 1 Always in rpm, even when operating at Constant Surface Speed.

4. SINGLE BLOCK TREATMENT

The CNC considers a "Single block" the group of blocks between a G47 and a G48.
After executing function G47, the CNC executes all the following blocks until executing a block containing function

G48 even when in Single Block mode.

If is pressed while executing a "single block" in Automatic or Single-Block mode, the CNC keeps executing
the rest of the blocks until it runs into a G48 and it, then, interrupts program execution.

While function G47 is active, the Manual Feedrate Override switch and the spindle speed override keys will be disabled,
thus the program will be executed at 100% of the programmed F and S values.

Functions G47 and G48 are modal and incompatible with each other.
On power-up, after executing an M02/M30, after an EMERGENCY or a RESET, the CNC assumes G48.

5. TWO ELECTRONIC HANDWHEELS ARE NOW POSSIBLE

From this version on, up 2 electronic handwheels may be used one for the X axis and another one for the Z axis. The
4th axis and the Live Tool will no longer be available. The feedback inputs will be used as follows:

A1 - X axis; A2 - Z axis handwheel; A3 - Z axis; A4 - 3rd axis or "C" axis; A5 - Spindle; A6 - X axis handwheel

The handwheels will be operative when selecting the JOG mode. One of the handwheel positions must also be selected
at the Manual Feedrate Override switch of the operator panel.

The possible positions are: 1, 10 and 100, which indicate the multiplying factor applied to the pulses coming from the
electronic handwheel.

P501 P622(2) P622(1) Resolution

1 0 0 0.001 mm 0.0001"
2 0 1 0.002 mm 0.0002"
5 1 0 0.005 mm 0.0005"

10 1 1 0.010 mm 0.0010"

This way and after applying the multiplying factor, one obtains the axis moving units. These units correspond to the
units used for the display format

Example: Handwheel Resolution : 250 lines per turn

When attempting to "crank" an axis faster than its maximum feedrate (machine parameters "P110, P310"), the CNC will
limit the actual axis feedrate to that parameter value ignoring the rest of the pulses supplied by the handwheel, thus
preventing a Following Error message from being issued.

5.1 MACHINE PARAMETERS FOR THE HANDWHEELS:

P622(6) = 0 There is no electronic handwheel associated with the Z axis
P622(6) = 1 There is electronic handwheel associated with the Z axis

P609(1) = 0 The electronic handwheel being used is not a FAGOR 100P model.
P609(1) = 1 The electronic handwheel being used is a FAGOR 100P model.

This parameter makes sense when using a single handwheel associated with the X axis. It indicates
whether or not it is a FAGOR 100P with axis selector button.

P500 Counting direction of the X axis handwheel (No / Yes)
P622(5) Counting direction of the Z axis handwheel (0 / 1)

P602(1) Feedback units of the X axis handwheel (0 = millimeters /1 = inches)
P622(3) Feedback units of the Z axis handwheel (0 = millimeters /1 = inches)

P501 Square-wave feedback resolution of the X axis handwheel.
P622(1,2) Square-wave feedback resolution of the Z axis handwheel.

P602(4) Multiplying factor for X axis handwheel feedback pulses (0= x4 / 1= x2)
P622(4) Multiplying factor for Z axis handwheel feedback pulses (0= x4 / 1= x2)

P621(2) = 0 Handwheel disabled for Manual Feedrate Override (MFO) switch positions other than the

handwheel positions.

P621(2) = 1 When the MFO is at a position other than those for the handwheel , the CNC takes it into account

and applies a "x1" multiplying factor.

Example: Having a Fagor electronic handwheel (25 lines per turn) set as follows:

P602(1)=0 Millimeters; P501=1 Resolution 0.001 mm.; P602(4)=0 x4 Multiplication factor
Depending on the position of the MFO switch (Manual Feedrate Override), the selected axis will move:
Position 1 1 x 25 x 4 = 0.100 mm per turn
Position 10 10 x 25 x 4 = 1.000 mm per turn
Position 100 100 x 25 x 4 = 10.000 mm per turn

5.2 USING ELECTRONIC HANDWHEELS

The machine uses one electronic handwheel

When using a single electronic handwheel, it must be connected to A6.
If the handwheel is a FAGOR 100P type, machine parameter "P609(1)" must be set to "1".
Once the desired handwheel position has been selected at the MFO switch, press one of the JOG keys of the axis

to be jogged. The selected axis appears highlighted.
When using a FAGOR handwheel with an axis selector button, the desired axis can also be selected as follows:
* Press the push-button on the rear of the handwheel. The CNC selects the first axis and it highlights it.
* By pressing the button again, the next axis is selected and so on, rolling over from the last axis to the first one.
* By keeping the button pressed for more than 2 seconds, the CNC de-selects the currently selected axis.
The selected axis will be jogged as the handwheel is turned, reversing directions when reversing the turning direction

of the handwheel.

MFO Switch position Distance per turn

1 0.250 mm or 0.0250 inch

10 2.500 mm or 0.2500 inch

100 25.000 mm or 2.5000 inches

- 7 -

When trying to move an axis faster than the maximum feedrate allowed (machine parameter "P110, P310"), the CNC
will limit the actual feedrate to that parameter value ignoring the additional pulses, thus, avoiding following error
messages.

The machine uses two electronic handwheels

Each axis will move as its associated handwheel is turned, reversing its direction as the handwheel turning direction
is reversed and according to the selected MFO switch position.

When trying to move an axis faster than the maximum feedrate allowed (machine parameter "P110, P310"), the
CNC will limit the actual feedrate to that parameter value ignoring the additional pulses, thus, avoiding following
error messages.

Version 7.2 (April 1997)

1. SCREEN SAVER

The screen saver function works as follows:

After 5 minutes without pressing a key or without the CNC refreshing the screen, the screen goes blank. Press any
key to restore the display.

Machine parameter "P619(5)" indicates whether this feature is to be used or not.

P619(5) = 0 This feature is not being used.
P619(5) = 1 This feature is being used.

2. JOGGING FEEDRATE

From this version on, machine parameter P812 sets the axis jogging feedrate selected by the CNC when accessing the
JOG mode.

If while in JOG mode, the conditional input (block skip), pin 18 of connector I/O1, the CNC does not allow entering
a new F value. Only the feedrate override (%) may be varied by means of the MFO switch.

3. RAPID TRAVERSE KEY IN JOG MODE

Whenever the conditional input (block skip), pin 18 of connector I/O1, the CNC will ignore the rapid traverse key

Version 7.4 (May 1999)

1. NEW MACHINE PARAMETER ASSOCIATED WITH THE M FUNCTIONS

Machine parameter "P620(8)" indicates when the M3, M4, M5 functions are sent out while accelerating or decelerating
the spindle.

2. CANCEL TOOL OFFSET DURING A TOOL CHANGE

From this version on, it is possible to execute a "T.0" type block inside the subroutine associated with the tool to cancel
the tool offset. This lets move to a particular position without the need for cumbersome calculations.

Only the tool offset may be canceled (T.0) or modified (T.xx). The tool cannot be changed (Txx.xx) inside the
subroutine associated with the tool.

3. DIVIDING FACTOR FOR FEEDBACK SIGNALS

Parameters P620(5), P620(6), P613(8) and P613(7) are used together with P602(6), P602(5), P612(5) and P614(5) which
indicate the multiplying factor to be applied to the feedback signals of the X, Z, 3rd and 4th axes respectively.

X axis Z axis 3rd axis 4th axis
P602(6) P602(5) P612(5) P614(5)
P620(5) P620(6) P613(8) P613(7)

Indicate whether the feedback signals are divided (=1) or not (=0).

P620(5)=0, P620(6)=0, P613(8)=0 y P613(7)=0 They are not divided
P620(5)=1, P620(6)=1, P613(8)=1 y P613(7)=1 They are divided by two.

Example: We wish to obtain a resolution of 0.01 mm with a squarewave encoders mounted on the X axis with 5mm

pitch ballscrew.

Nr of pulses = ballscrew pitch / (Multiplying factor x Resolution)

With P602(6)=0 & P620(5)=0 x4 multiplying factor Nr of pulses = 125
With P602(6)=1 & P620(5)=0 x2 multiplying factor Nr of pulses = 250
With P602(6)=0 & P620(5)=1 x2 multiplying factor Nr of pulses = 250
With P602(6)=1 & P620(5)=1 x1 multiplying factor Nr of pulses = 500

Version 7.6 (July 2001)

1. G75 AFFECTED BY FEEDRATE OVERRIDE

From this version on, there is a new machine parameter indicating whether G75 is affected by the feedrate override or
not.

P623(1) = 0Not affected. It is always at 100%, like in previous versions.
P623(1) = 1It is affected by the Feedrate override.

2. FEEDBACK FACTOR.

From this version on, there is a new machine parameter to set the resolution of an axis having an encoder and a leadscrew.

P819 Feedback factor for the X axis P820 Feedback factor for the 3rd axis

P821 Feedback factor for the Z axis P822 Feedback factor for the 4th axis
Values between 0 and 65534. The “0” value indicates that this feature is not being used.
Use the following formula to calculate the “Feedback Factor” :

Feedback factor = (Gear Ratio x Leadscrew pitch / Number of Encoder pulses) x 8.192

Examples: Gear Ratio 1 1 2 1

Leadscrew pitch 5000 6000 6000 8000 (microns)
Encoder 2500 2500 2500 2500 (pulses/turn)
Feedback factor 16384 19660.8 39321.6 26214.4

The machine parameters only admit integer values and sometimes the “Feedback Factor” has decimals. In those cases,
assign the integer part to the machine parameter and use the leadscrew compensation table to make up for the decimal
part.

The values to be entered in the table are calculated with the following formula:

Leadscrew position = Leadscrew Error (microns) x Integer of feedback factor / decimals of the feedback factor

For example: Gear ratio = 1 Leadscrew pitch = 6000 Encoder = 2500

Feedback factor = 19660.8 Machine parameter = 19660
For a leadscrew error of 20 microns Leadscrew position = 20 x 19660 / 0.8 = 491520
Going on with the calculation, we come up with the following table.

Leadscrew position Leadscrew error
P0 = -1966.000 P1 = -0.080
P2 = -1474.500 P3 = -0.060
P4 = -983.000 P5 = -0.040
P6 = -491.500 P7 = -0.020
P8 = 0 P9 = 0
P10 = 491.500 P11 = 0.020
P12 = 983.000 P13 = 0.040
P14 = 1472.500 P15 = 0.060
P16 = 1966.000 P17 = 0.080

3. NEW MODEL

From this version on, the new model TLI is now available.
It offers the same features as the TGI model and it is sold together with the motors and ACS drives..

3.2.6. Selection of a program

Same as section 3.6.6. in EDITING mode (6).

8025/8030 CNC OPERATING MANUAL 23

3.2.7. Creating a program

The creation of a program in PLAY BACK mode is the same as in EDITING mode except
that the axes can be moved by means of the JOG keys. The axis coordinate values are displayed
at the bottom of the screen.

In a block which only contains the coordinates of one point, after using the JOG keys to move
the axes, press ENTER and the coordinates of the point will be stored in the memory. Every
time the ENTER key is pressed, the coordinates of the point according to the 3 active axes at
that moment will be stored in memory.

In order to activate an axis which is not active at that time, the key of the corresponding axis
(X,Y,Z,W,V) must be pressed.

If in addition to the coordinates of a point it is desired to write into the block further information
such as G,S,M,T functions etc., each time the key of the corresponding axis is pressed the CNC
will take as the value of the axis the coordinate at which the machine is at that moment.This
method of editing is highly practical when creating a program for copying a part using functions
G08 and G09.

When G08 has been written into a block requiring it, use the JOG keys to move the machine
to the end point of the tangent arc to the previous path, then press ENTER and the block will
be stored in the memory.

When G09 has been written into a block which requires it, use the JOG keys to move the
machine to an intermediate point on the arc and press the ENTER key. The CNC will take the
coordinates as those of the intermediate point on the arc. Then move the machine to the end
point of the arc and once the ENTER key has been pressed the block will be stored in the
memory.

3.5.6. Measurement and loading of the tool dimensions in the offset table.

Once the JOG mode has been chosen, the tool dimensions can be measured and introduced into
the table, by using a part with known dimensions. For this, machine parameter P806 will be
assigned a value of 0. The sequence to be executed is as follows:

. Press the function key [TOOL MEASUREMENT]
. Press X.
. Key in the dimension of the part according to the X axis. This value will be in radii or

diameters, depending on how the machine is working.

. Press ENTER.
. Press Z.
. Key in the part dimension according to the Z axis.
. Press ENTER.
. Key in the desired tool number (T2.2).
. Press START.
. Move the X axis with the manual controls, until the part is touched.
. Press X.
. Press [LOAD]. At that moment the new X dimension of the tool calculated by the control

becomes active, due to which the dimension displayed on the X axis must be the same as the
one introduced as the radius or diameter of the part.

. Move the Z axis with the manual controls, until the part is touched.
. Press Z.
. Press [LOAD]. At that moment the new Z dimension of the tool calculated by the control

becomes active, due to which the dimension displayed on the Z axis must be the same as the
one introduced as the radius or diameter of the part.

. If you want to do the same with another tool, it is necessary to begin once more by keying

in the new tool (T2.2); the rest of the operation is the same as the first tool.

. To go on to work in the normal way in the MANUAL mode, the [TOOL MEASUREMENT]

key must be pressed.

8025/8030 CNC OPERATING MANUAL 35

3.5.7. Operation of the CNC as a readout

Once the JOG operating mode is selected, if the external MANUAL input is activated, the
CNC acts as a readout. In this case, the machine has to be moved by means of external
controls and the analog signals must be generated outside the CNC.The S and M functions
may be entered in this form of operation. If when operating in this mode, the software
travel limits (set via machine-parameters) are overrun, the CNC will send the relevant
error code and will only allow the machine to be moved to bring it back to the permitted
zone.

3.5.8. Change of measuring units

Every time the key I is pressed the measuring units change from mm to inches and vice­versa.

3.5.9. CNC Reset

Once the JOG mode is selected, when is pressed, the CNC returns to the initial
conditions.

36 8025/8030 CNC OPERATING MANUAL

3.5.10. Handwheel operation

When an electronic handwheel is fitted, with this option the axes can, one at a time, be
moved manually. For this:

- Select the JOG operation mode.

- Turn the front knob to one of the positions.

- Press any of the two JOG keys which correspond to the axis to be moved by the
Handwheel. If a FAGOR Handwheel (mod 100 P) is used, the axis can also be selected
by means of the built-in selector button; the relevant axis will be highlighted on the
CRT.

- Turn the Handwheel, the axis will move according to the setting of the relevant machine­parameter multiplied by the factor selected with the switch (X1,X10,X100).

It should be borne in mind that if we wish to move an axis at a speed of over G00
corresponding to this axis, the CNC will assume this as maximum, ignoring additional
pulses. In this way the generation of following errors is avoided.

To change the axis being jogged:

- Press any of the two JOG keys of the new axis or the axis selector button if a FAGOR
Handwheel (mod 100 P) is used.

- Turn the Handwheel.

To end the Handwheel operation.

- Turn the M.F.O. switch to any other position or press the STOP key or keep the axis
selector button pressed until the CRT stops displaying (blinking) the selected axis, if a
FAGOR Handwheel (mod 100 P) is used.

8025/8030 CNC OPERATING MANUAL 37

3.5.11. Measuring and loading of tool offsets with a probe.

As long as the machine parameter P806 is assigned a value different from zero the CNC permits
that, in the JOG mode, the tool dimensions can be quickly measured and loaded with a probe.
To do this, a tool measuring probe must be installed with its sides parallel to the axes and in
an established position on the machine.

The values on the sides of the probe on each axis and with respect to the machine reference zero
must be entered in the following parameters:

P902 minimum (X1) value according to X axis (in radii)
P903 maximum (X2) value according to X axis (in radii)
P904 minimum (Z1) value according to Z axis
P905 maximum (Z2) value according to Z axis

Probe

The sequence to be followed is:

1- Press the [TOOL MEASUREMENT] key.
2- Select the tool to be measured by keying in: Txx.xx START.
3- Move the tool with the JOG keys up to a position close to the probe side to be touched.
4- Press the key of the axis to be measured (X or Z).
5- Press the JOG key that indicates in which direction the axis must be moved to carry out

the probing movement. The feedrate is established by P806.

6- Once the probing is done, the machine stops and the CNC loads in the corresponding

position of the tool offset table the X or Z value measured; setting to zero the K value.

7- Repeat from step 3 to measure and load the length of the tool in the other axis.
8 - Once the tool has been removed, repeat from point 2 for the measurement and loading of

the tools.

The FEEDRATE override knob has no effect during the probing movements and is set to
100%

The radius values of the R plate and the F shape factor of the tool are introduced manually by
means of mode o operation 8 or by means of programming the G50 function.

To go back to the JOG mode, press the [TOOL MEASUREMENT] key.

3.10. GRAPHICS

CNC 8030 model TS or TG have GRAPHIC REPRESENTATION and by means of this
feature the tool path can be displayed on the CRT, as the program is being executed.

This feature can be applied in one of the following modes: AUTOMATIC, SINGLE
BLOCK, TEACH IN, DRY RUN.

In DRY RUN mode, if THEORETICAL PATH (4) is selected, the system checks the
program and displays the theoretical tool- center’s path in solid lines, ignoring its
dimensions.

Nevertheless, if mode 0 or 1 is selected in the same operating mode (DRY RUN), the tool
center’s path will be displayed in dotted lines.

If, when executing a program in DRY RUN operation in modes 0,1 or 4, there is a block
involving movement plus the function (Tx.x) the relevant path will not be displayed unless
the machine is a machining center.

In the remaining modes, the tool’s real path is displayed in dotted lines. The distance
between dots varies according to the value of F.

8025/8030 CNC OPERATING MANUAL 63

3.10.1. Display area definition

Prior to the representation of graphics on the CRT, the display area must be defined before
the program is run. To do this, after selecting the desired operation mode.

- Press the [GRAPHICS] key.

- Press the [DEFINE AREA-V] key.
Next, the values of the coordinates X, Z must be keyed in from the point at which it is

required that it appear in the center of the screen and the value of the width we want it to
represent. After keying in each value, the ENTER key must be pressed.

The definition of the display area must be made every time the CNC is switched on, if it
is required to use the graphic representation feature.

Then, execute the program; the position and size of the graphic will depend on the values
given to the center point and width. The coordinate values of the point being displayed are
shown at the top of the CRT. The value of the width is displayed at the bottom.

When a program is being run in the DRY RUN operating mode, it is possible to vary the
speed the diagram is drawn on the screen, by means of the FEED RATE switch.

64 8025/8030 CNC OPERATING MANUAL

3.10.2. Zooming (windowing)

The CNC has a ZOOM function by which entire graphics or parts of them can be enlarged
or reduced by this feature. To use this ZOOM function the program must be either
interrupted or completed.

Press the key which corresponds to the view in which the zooming is desired. Then press
[ZOOM] and a rectangle identifying the window will be displayed over the existing
graphic.

Its dimensions can be altered pressing or on the front panel and its position
by using cursor moving keys.

The coordinate values of the window’s center and the width and the percentage are
displayed on the CRT. The display of values can be useful to check the coordinate values
of a particular point (by placing the center of the window over it) and also to measure
distances between two points.

If [EXECUTE] is pressed, the windowed area will fill the CRT.
Using the FEEDRATE override knob, the graphic drawing speed can be altered.
To repeat the whole ZOOM sequence, start by pressing [ZOOM] as before.
To exit the ZOOM mode and continue, press [END].

3.10.3. Redefinition of the display area by the ZOOM function

With the ZOOM function active after pressing [ZOOM], if ENTER is pressed
[EXECUTE] the position and width of the rectangle override the previous values given
to the display area when it has been defined.

The position and the size of the graphic can thus be altered.

Atention:

It is recommended that a sufficiently large width be assigned to the
display area the first time it is defined to guarantee that the complete
graphic will be displayed on the screen and then ZOOM in to center it and
enlarge it.

When the ZOOM function is used, it is necessary to bear in mind that the
CNC will keep information on approximately the last 500 blocks with
movement which have been executed, therefore, if the programme has
more blocks with movement, only those retained will appear in the new
diagram.

8025/8030 CNC OPERATING MANUAL 65

3.10.4. Deletion of graphics

Press DELETE to erase the graphic displayed, once the program has been executed or
interrupted.

3.10.5 Graphic representation in colour (CNC 8030 TS)

Whenever only one of the 4 views possible have been selected, every time the Tool (T2)
is changed, the path will be drawn in a different color (3 colors).

> When the first character of the block to be executed is not an "N".
> When while BACKGROUND editing, the program in execution calls a subroutine located in the pro-

gram being edited or in a later program.
The order in which the part-programs are stored in memory are shown in the part-program directory.

If during the execution of a program, a new one is edited, this new one will be placed at the end of

the list.
002 Too many digits when defining a function in general.
003 A negative value has been assigned to a function which does not accept the (-) sign or an incorrect value

has been given to a canned cycle parameter.
004 A canned cycle has been defined while function G02, G03 or G33 was active.
005 Parametric block programmed wrong.
006 There are more than 10 parameters affected in a block.
007 Division by zero.
008 Square root of a negative number.

does not exist.
017 This error is issued in the following cases:

> Negative or too large thread pitch value.

> Synchronization factor K of the synchronized tool too large.
018 Error in blocks where the points are defined by means of angle-angle or angle-coordinate.

028 An attempt has been made to select a tool offset at the tool table or a non-existent external tool (the

number of tools is set by machine parameter).
029 Too large a value assigned to a function.

This error is often issued when programming an F value in mm/min (inch/min) and, then, switching to

work in mm/rev (inch/rev) without changing the F value.
030 The programmed G function does not exist.
031 Tool radius value too large.

032 Tool radius value too large.

is required.

> If the tangential entry is to be applied to an arc (G02, G03), The tangential entry must be defined in

a linear block.

042 This error is issued when programming a tangential exit as in the following cases:

> There is no room to perform the tangential exit. A clearance of twice the rounding radius or greater is

required.

> If the tangential exit is to be applied to an arc (G02, G03), The tangential exit must be defined in a

linear block.
043 Polar origin coordinates (G93) defined incorrectly.
044 Function M45 S programmed wrong (speed of the live tool).
045 Function G36, G37, G38 or G39 programmed incorrectly.

> If function G76 (block content) has been programmed without having programmed G76 P5 or G76 N5

before.
> If in a G76 P5 or G76 N5 type function does not contain the 5 digits of the program number.
> If while a program is being generated (G76 P5 or G76 N5), its program number is changed without

cancelling the previous one.
> If while executing a G76 P5 type block, the program referred to is not the one edited. In other words,

that another one has been edited later or that a G76 P5 type block is executed while a program is being

leadscrew error compensation tables from the EEPROM memory.

Atention:

The ERRORS indicated with "*" behave as follows:

They stop the axis feed and the spindle rotation by cancelling
the Enable signals and the analog outputs of the CNC.

They interrupt the execution of the part-program of the CNC if
it was being executed.

The ERRORS indicated with "**" besides behaving as those with an
"*", they activate the INTERNAL EMERGENCY OUTPUT.
