P621(4). DIVIDING FACTOR FOR ELECTRONIC HANDWHEEL FEEDBACK
SIGNALS
Machine parameter P621(4) is used with P602(4) and P621(5) which indicate the multiplying factor for the electronic handwheel feedback
signals for the 1st and 2nd axis respectively.
Machine parameter P627(1) indicates whether all handwheel feedback signals are to be divided or not.
P621(4)=0
They are not divided.
P621(4)=1
All handwheel feedback signals are divided by two.
Examples for the X axis so the CNC assumes 100 pulses/turn with 25, 50 and 100 line handwheels:
25 line Fagor handwheel:
50 line Fagor handwheel:
100 line Fagor handwheel:
P602(4)=0 and P621(4)=0
P602(4)=1 and P621(4)=0
P602(4)=1 and P621(4)=1

JOG WITH MASTER HANDWHEEL
With this feature it is possible to jog the machine with the Master Handwheel once the path has been defined.
Requirements:
The control of the "Jog with Master Handwheel" is carried out with the Second Handwheel. Therefore, the machine must have
two electronic handwheels and none mechanical.
Parameter setting:
Machine parameter "P622(6)" indicates whether this feature is being used or not.
P622(6) = 0
"Jog with Master handwheel" is not available.
P622(6) = 1
"Jog with Master handwheel" is available.
As stated above, the control of the "Jog with Master Handwheel" is carried out with the Second Handwheel. Therefore, the
machine must have two electronic handwheels and none mechanical. This means that:
P621(7)=1
The machine does not use mechanical handwheels.
P622(3)=0
It uses two electronic handwheels.
P609(1)=0
The first handwheel is not a FAGOR 100P model.
The Master handwheel is connected via connector "A4". It admits both sine-wave and square-wave differential signals.
This implies setting the following machine parameters as follows:
P621(6)
Counting direction of the "Master Handwheel".
P621(3)
Feedback units of the "Master Handwheel".
P621(1,2)
Feedback resolution of the "Master Handwheel".
P621(5)
Feedback multiplying factor for the "Master Handwheel".
Selection:
a) CNC Models: 800TI and 800TGI. From the PLCI.
Once all machine parameters have been set, PLCI output O39 must be used to enable or disable the "Jog with Master Handwheel"
feature.

Basic Operation. (P622(6)=1, O39=1)
a) When the machine is stopped.
Only the first handwheel is enabled, the second one (Master) is disabled.
Therefore, only the X axis may be jogged with the handwheels.
b) When the machine is running (CNC in Execution).
The axes do not start moving until the Master Handwheel is turned.
The axis feedrate depends on the turning speed of the Master Handwheel. If it stops, the axes also stop.
If the Master Handwheel is turned in the opposite direction, the axes also invert their moving direction (Return Function for one
block only).
c) The "Jog with Master Handwheel" feature may be used with any type of execution, be it a cycle, an ISO-coded program, a
Chamfer, etc.
Usually, with the CNC in execution, the first handwheel is disabled, except for the semi-automatic mode of the automatic operations:
"Taper Turning" and "Rounding".
On both Semi-automatic operations, the Master Handwheel controls the feedrate of the tool path and the First Handwheel will
move the X axis.
"Jog with Master Handwheel" feature disabled. (P622(6)=1, O39=0)
When this feature is disabled, PLC output O39 is set to "0" and the handwheels operate like until now (as on previous versions).
2.
DYNAMIC GRAPHICS WHILE IN EXECUTION
Until now, with the 800T CNC, a part program could be simulated (verified) graphically before running it.
From now on, it is also possible to display dynamic graphics of the machining path while in execution.
Requirements:
This application requires a 800TG or 800TGI CNC model (G for graphics).
Operation:
When running an Automatic Operation, a Part program, the ISO-coded program in Automatic or Single Block mode, it is now
possible to display the machining path dynamically in the execution stage.
To do this, once the execution has started, the following keys may be pressed:
[4]
The CNC displays the graphics screen.
[3]
The CNC shows the "Command, Actual and To-go" coordinates of the axes and, at the top of the screen, the values
of the Arithmetic parameters.
[2]
The CNC displays the Following Error (axis lag) in large characters.
[1]
The CNC displays the actual axis position in large characters.
[0]
The CNC returns to the standard display.
3.
WORK ZONE / EXCLUSION ZONE
With this feature it is possible to select a predefined zone as work zone or exclusion zone from the PLCI.
Requirements:
This application requires an 800TI or 800TGI CNC model since one must use outputs O46 and O47 of the PLCI to set the zone
as work zone or exclusion zone.
Parameter setting:
Machine parameter "P622(5)" indicates whether the CNC allows setting a work zone or an exclusion zone.
P622(5) = 0
This feature is not available.
P622(5) = 1
This feature is available.
When using this feature "P622(5)=1" the following machine parameters
must also be set to define the zone to be considered either as work zone
or exclusion zone.
P902 Most positive X coordinate
P903 Least positive X coordinate
P904 Most positive Z coordinate
P905 Least positive Z coordinate
The CNC must be turned off and back on in order for the new parameter
values to be assumed.
-3-
Selection:
Once all machine parameters have been set, PLCI outputs O46 and O47 must be used to select the predefined zone either as a
work zone or as an exclusion zone.

Zone enabled as Exclusion Zone (No-entry zone)
O46 = 1
O47 = 1
Feature disabled
Basic operation. "P622(5)=1"
On power-up, the CNC assumes the zone set by machine parameters "P902, P903, P904 and P905".
Nevertheless, the zone boundaries may be changed via part-program by allocating the new values to the following arithmetic
parameters:
P206
Most positive X coordinate
P207
Least positive X coordinate
P208
Most positive Z coordinate
P209
Least positive Z coordinate
The CNC will then assume these new values; but it will not modify the actual settings of machine parameters "P902, P903, P904
and P905".
On the other hand, it must be kept in mind that, on power-up, the CNC will reset these zone boundaries to the values set by machine
parameters.
As described earlier, this predefined zone may be enabled either as a work zone (no-exit) or as an exclusion zone (no-entry) from
the PLCI by means of outputs O46 and O47.
When set as a work zone, the CNC acts as follows:
• The axes cannot be jogged out of this zone by using the jog keys or the handwheels.
• If attempted to do so during execution, the CNC will issue error 67: «X, Z Limit Error»
When set as an exclusion zone, the CNC acts as follows:
• The axes cannot be jogged into this zone by using the jog keys or the handwheels.
• If attempted to do so during execution, the CNC will issue error 67: «X, Z Limit Error»
4. MANUAL SPINDLE GEAR CHANGERS
Operation on previous versions
To manually change the spindle speed range (gear), machine parameter "P601(1)" had to be set to "0".
When the new selected spindle speed "S" involved a gear change, the CNC displayed a message indicating which
range had to be selected.
The operator had to proceed as follows:
1st- Stop the spindle
2nd- Manually change gears
3rd- Restore spindle rotation
4th- Press [ENTER]
The CNC resumed program execution.
Operation on current and future versions
To manually change the spindle speed range (gear), machine parameter "P601(1)" must set to "0".
When the new selected spindle speed "S" involves a gear change, the CNC displays a message indicating which range
has to be selected.
The operator must proceed as follows:
1st- Manually change gears
2nd- Press [ENTER]
The CNC restores spindle rotation and resumes program execution.

5.
VARIABLE BACKLASH COMPENSATION
Until now, the 800T CNC allowed for a single leadscrew backlash compensation.
From now on, it is also possible to compensate for motion-reversal backlash depending on the particular backlash areas of the
axes.
Requirements:
The leadscrew error compensation tables are now used for leadscrew error compensation and for this "Variable Backlash
Compensation" (at the same time).
Parameter setting:
Machine parameters "P622(7)" and "P622(8)" indicate whether this feature is available or not.
P622(7) = 0
Not available for the Z axis.
P622(7) = 1
Available for the Z axis.
P622(8) = 0
Not available for the X axis.
P622(8) = 1
Available for the X axis.
In order to use "Variable Backlash Compensation", regular leadscrew compensation must also be activated.
P605(2) = 0
X axis Leadscrew error compensation (0= No, 1= Yes)
P605(1) = 0
Z axis Leadscrew error compensation (0= No, 1= Yes)
Operation:
The first 15 points of the table are for the positive direction and the other 15 for the negative direction.
When compensating for leadscrew error, the amount of backlash is the difference between both graphs.
When leadscrew error compensation is not to be used, all the values of one of the tables must be set to "0"; thus, the other graph
will correspond to the leadscrew backlash.
Notes:
• Both graphs must meet all the requirements of the leadscrew error compensation tables.
• One of these requirements states that the Machine Reference Zero (home) must be assigned an error of "0".
• If the leadscrew has some backlash at this Machine Reference Zero point, that amount of backlash must be allocated
to machine parameter P109 or P309 (Backlash for the X axis or Z axis) and all the remaining points of the table must
be offset by that amount.
Example:
Operation:
When using "Variable Backlash Compensation", the CNC operates with leadscrew error compensation and, therefore, it applies
at all times the backlash compensation set in the table for that point and in the machining direction.
When the axis movement is reversed, the CNC swaps graphs restoring or applying the amount of backlash compensation and
direction corresponding to that point.

(July 1996)
WORK ZONE / EXCLUSION ZONE DETECTION
When using this feature, the CNC prevents the axes from exiting or entering this zone while jogging them with either the jog keys or
the electronic handwheel.
The operator might suspect a malfunction since the CNC does not issue any message. From this version on, in these cases, the CNC
will behave as follows:
* When the zone has been set as a Work Zone, the CNC will set PLCI input I46 high when trying to exit the selected zone.
* When the zone has been set as a Work Zone, the CNC will set PLCI input I46 high when trying to enter the selected zone.
2.
RESUME EXECUTION AT MID-PROGRAM
If while a part, the program is interrupted (due to a power failure, etc.), it is now possible to resume execution from the interrupted program
on. This way, there is no longer need to repeat the whole program, thus saving considerable amount of time.
To resume program execution, follow these steps:
1st Select the DRO mode, the one appearing on CNC power-up after the "General Test Passed".
In this mode, no cycle appears selected.
2nd Press [RECALL] to open the part-programs window.
3rd Select the part that was running. Use the up and down arrow keys to position over the desired part program and press
[RECALL].
4th Use the up and down arrow keys to select the operation being interrupted and press
The CNC will executed the selected operation and it will resume the part-program running it to the end.

MODIFICATIONS ON THE OPERATION WITH A MASTER HANDWHEEL
The operation with the master handwheel is now as follows:
a) When the machine is stopped.
Only the first handwheel is enabled, the second one (master) does not work.
Therefore, only the X axis can be jogged with a handwheel.
b) When the machine is running (CNC in Execution).
Only the Master handwheel is enabled, the first handwheel does not work.
The axes start moving when turning the Master Handwheel.
The feedrate of the axes depend on the turning speed of the Master Handwheel
When the handwheel stops, the machine also stops.
When the Master Handwheel is turned in the opposite direction, the CNC also reverses the moving direction (Retrace Function
of a single block).
c) Semiautomatic Rounding Operation
The Semiautomatic Rounding operation starts when turning the Master Handwheel.
When stopping the Master Handwheel, the execution is interrupted.
When turning the Master handwheel again, execution is resumed. The turning direction of the handwheel cannot be changed.
When the operation is over, the CNC ignores the turning of the Master Handwheel for 1.4 seconds. Thus preventing another
operation from being started.
After this time, when the Master Handwheel is turned, the CNC starts executing a new operation in the indicated direction.
-6-
d) Semiautomatic Taper Turning Operation
The Semiautomatic Taper Turning Operation starts when turning the Master Handwheel.
When stopping the Master Handwheel, the execution is interrupted.
When turning the Master handwheel again, execution is resumed.
When turning the Master Handwheel in the opposite direction, the operation is over. A new turn of the Master Handwheel in
any direction implies the execution of a new operation in the indicated direction.

SOFTWARE VERSION OF THE CNC
From this version on, when accessing the EPROM checksum screen,
[Auxiliary Modes] [Special Modes] [8]
The CNC will show the checksum of each EPROM and the Software version of the CNC. For example: Version 6.1

TOOL CHANGE INDICATOR FOR THE PLC (I97)
On machines with a manual tool changer, when the CNC detects that the tool must be changed, it interrupts the execution and it displays
a message for the operator to proceed with the tool change.
Certain precautions must be taken sometimes when changing tools. Those conditions must be handled by the PLC.
Therefore, from this version on, when the CNC displays the tool change warning message, it also activates the PLC input I97 and
it cancels it when the message is removed.

Scale offset or Home position (Machine Reference: M) with
respect to the Scale "zero" point. X, Z axes.
Linear transducers (scales) with coded Io have a graduated
scale with their own Scale "zero" point. Therefore, a 20 mm or

to the Scale "zero" point.
Reference point.
When the feedback system has a coded Io, this point is only used when leadscrew error compensation is needed. The leadscrew
error on this point must be "0".
Scale offset setting
The scale offset must be adjusted on one axis at a time. The following procedure is recommended:
* Indicate by parameters "P600(7) & P600(6)" the up or down flank of the marker pulse (Io) of the feedback system.
* Indicate by parameters "P618(8) & P618(7)" the home searching direction for the axes.
* Set parameters "P807 and P808" with the home searching feedrate for the axes.
* Set parameters " P908 and P909" to "0" (scale offset).
Position the axis at the right position and execute the home search command for that axis..
[X] or [Z], [up arrow] keys and
When done with the home search, the CNC will display the axis position with respect to the scale's Zero point.
-7-
* After moving the axis to Machine Reference Zero point (home) or up to a known position with respect to home, Jot down the
position reading of the CNC for that known position.
The value to allocate to the machine parameter setting the scale's offset must be calculated with the following formula:
Value = CNC reading at that point - Home coordinate of that point
Example for the X axis: If the known position is physically located at 230 mm from Machine Reference Zero (home) and the
CNC shows that its position is 423.5 mm, the scale offset will be:
Machine parameter P908 = 423.5 - 230 = 193.5 mm.
* After setting the machine parameter with this value, press the [RESET] key so that value is assumed by the CNC.
* A new home search must be carried out for the proper values to be assumed for that axis.
2.
THREADING WITH CONSTANT PENETRATION PASSES
From this version on, the penetration of each pass will depend on the sign assigned to parameter ∆
When ∆ positive, the penetration of each pass depends on the corresponding pass (∆ n)
With ∆ negative, the penetration passes remain constant with the absolute value of parameter ∆
3.
GENERATING AN ISO-CODED PROGRAM
With this CNC, the ISO code (low level) for an operation or a part-program may be generated.
To use this feature, machine parameter "P623(2)" must be set to "1".
This ISO program always has the number: 99996 and can be stored either at the CNC or at a PC.
Program 99996 is a special user program in ISO code and can be:
Generated from an operation or a part-program.
Edited at the CNC itself via menu option: "Auxiliary Modes - Edit program 99996"
Loaded into the CNC after being generated at a PC.
Generating the ISO program (99996) at the CNC.
This CNC has 7 K of memory space to store program 99996. If the generated program is larger than that, the CNC will issue the
relevant error message.
To generate program 99996, proceed as follows:
* If it is an operation, select or define the desired operation.
* If it is a part-program, select the desired one in the part-program directory and place the cursor on its header ("PART 01435".
A listing of the operations it consists of must appear).
* Press the keystroke sequence: [AUX] [7]. The CNC will show the graphic simulation screen.
* Press
. The CNC starts simulating the part and generating its ISO-coded program 99996.
* When done with the simulation, program 99996 stored in CNC memory will contain all simulated blocks in ISO code.
Generating the ISO program (99996) at a PC
Usually, the 99996 program generated from a part-program exceeds the available memory space of the CNC.
By using "DNC30", this program may be generated at a PC.
To do this, proceed as follows:
* Activate DNC communications and execute the DNC30 program at the PC.
* Select at the PC the menu option: "Program Management - Receive Digitizing".
* At the CNC, select the operation or place the cursor on the part-program header ("PART 01435"). A listing of the operations
it consists of must appear).
* Press [AUX] [8]. The CNC will display the graphic simulation screen.
* Press
. The CNC starts simulating the part and generating program 99996.
* When done with the simulation, the 99996 program generated at the PC will contain all the blocks simulated by the CNC in
ISO code.
This program can be executed at the CNC through the menu option: "Execute infinite program" of the DNC30.

P623(7) Adapts the X axis feedback encoder (0=No, 1=Yes)
P623(8) Adapts the Z axis feedback encoder (0=No, 1=Yes)
A typical case: Having a 1000 line for a 5 mm pitch ballscrew .
The calculations necessary to set the axis resolution will be made with the selected pulses (1000 or 1250)
3.
CROSS COMPENSATION
Cross compensation is used for compensating the measuring error suffered by the X axis when moving the Z axis.
P623(6) Cross compensation applied on to the X axis (0=No, 1=Yes)
When using cross compensation, no leadscrew compensation may be applied on the X axis (only on to the Z axis) since its
corresponding table is being used for cross compensation with the following values:
P00 = X:
?????.???
P01 = DX: ????.???
in order to properly apply cross compensation, set: P605(2)=1 and P623(6)=1.
Note: The cross compensation table must meet the same requirements as those for the leadscrew error compensation. See section
3.8.4 of the installation manual.

CANCEL TOOL OFFSET DURING TOOL CHANGE
From this version on, it is possible to execute, within a subroutine associated with the tool, a "T.0" type block to cancel the tool offset.
This allows to move to a specific position without having to do cumbersome calculations.
It is only possible to cancel (T.0) or change (T.xx) the tool offset. The tool cannot be changed (Txx.xx) within the subroutine associated
with the tool.

Machine parameters P620(5) and P620(6) are used together with P602(6) and P602(5) which indicate the multiplying factor of the
feedback pulses for the X and Z axes respectively.
They indicate whether x1 factor is applied to the feedback pulses (=1) or not (=0).
P620(5)=0 and P620(6)=0
P620(5)=1 and P620(6)=1
the x1 factor is NOT applied
the x1 factor is applied
Example: We would like to obtain a 0.01 mm resolution with a square signal encoder mounted on the X axis having a leadscrew pitch
of 5mm/turn.
Number of Encoder pulses = leadscrew pitch / (multiplying factor x Resolution)
Con P602(6)=0 and P620(5)=0
Con P602(6)=1 and P620(5)=0
Con P602(6)=0 and P620(5)=1
Con P602(6)=1 and P620(5)=1

(March 2002)
FEEDBACK FACTOR.
The resolution of the axis is determined by the leadscrew pitch and the number of pulses of the encoder mounted on the motor.
Sometimes, the resolution resulting from the available leadscrew / encoder combination does not match any of the resolution values
allowed for the machine parameters (1, 2, 5, 10 microns or ten-thousandths of an inch).
Example: With a 6 mm/turn leadscrew pitch and a 2500 line encoder, the resulting resolution values are:
Resolution = Leadscrew pitch / ( Nr of encoder pulses x multiplying factor).
With x1 multiplying factor 2.4 micron resolution
With x2 multiplying factor 1.2 micron resolution
With a x4 multiplying factor
0.6 micron resolution
A new axis machine parameter is now available to solve these cases and it is referred to as Feedback Factor in order to adapt the resulting
resolution to the existing setup.
P819 Feedback factor for the X axis P820 Feedback factor for the Y axis P821 Feedback factor for the Z axis
Values between 0 and 65534, a "0" value means that this feature is not being used.
Use the following formula to calculate the "Feedback factor":
Feedback Factor = (Gear ratio x Leadscrew Pitch / Encoder pulses) x 8.192
Examples:
Gear ratio
Leadscrew Pitch
Encoder
Feedback factor
1
4000

13,107.2

2500
39,321.6
1
8000
2500
26,214.4
(microns)
(pulses/turn)
The machine parameters only admit integers, but the Feedback Factor sometimes may have decimals. In those cases, set the machine
parameter to the integer part of that value and use the leadscrew error compensation table to make up for the decimal part.
The values for this table are calculated using the following formula:
Leadscrew position = Leadscrew error (microns) x Integer portion of feedback factor /Decimal portion of feedback factor
In this case: Gear ratio = 1 Pitch = 6000 Encoder = 2500
Feedback factor = 19,660.8 Machine parameter = 19660
For leadscrew error of 20 microns Leadscrew position = 20 x 19,660 / 0.8 = 491,520
The following table is obtained by using this calculation.
Leadscrew position
Amount of error at that position
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

FAGOR 800T CNC
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 800T CNC product.
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 800T 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.
Chapter 2 (Power and machine interface) shows how to connect the CNC to power A.C.
(Mains) and to the electrical cabinet.
Chapter 3 "Auxiliary Functions" shows how to access special operating modes.
To adapt the CNC to the machine, set the CNC machine parameters. We suggest that you
consult chapters 4, 5, 6 and the appendices related to the machine parameters listed in
numerical order.
Both appendices offer cross references indicating the section of the manual describing each
parameter.
When explaining each parameter in detail, chapters 4, 5 and 6, they sometimes refer to
chapter 7 (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.
Notes: The information described in this manual may be subject to variations due to
technical modifications.
FAGOR AUTOMATION, S.Coop. Ltda. reserves the right to modify the contents
of the manual without prior notice.

SUGGESTIONS FOR RS232C INTERFACE
*
Connecting and disconnecting the peripheral device
The CNC must be powered off when connecting or disconnecting
any peripheral device via this connector.
*
Cable length
The EIA RS232C standards specify that the capacity of the cable must not exceed
2500pF, thus, since the cables usually have a capacity between 130 and 170 pF/
m, their maximum length will be limited to 15 meters (50 feet).
It is suggested to use shielded cables and/or twisted-pair wires in order to minimize
interference between cables thus avoiding faulty communications over lengthy
cables.
It is recommended to use 7-conductor cables with a minimum section of 0.14 mm²
and overall shielding.
* Transmission speed (baudrate)
The most common baudrate used with peripherals is 9600 baud; but the CNC can
operate at up to 19200 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 wire
(pin 7 -GND-) thus avoiding reference points at different voltage levels since there
could be different voltages between both ends of long cables.

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.
* Work as FEED-HOLD. If this input is set low (0V) while moving the axes, the
CNC keeps the spindle on and stops the movement of the axes by cancelling
their analog outputs (0V) but keeping their enables activated.
When returning this signal high, the CNC will resume the axes movement.
* Work as TRANSFER INHIBIT. If this input is set low while executing a
motionless block, The CNC interrupts the execution of the program at the end
of the current block.
When returning this signal high, the CNC will resume the execution of the
program.
* The "M-DONE" signal will be used when machine parameter "P602" bit 7 has
been set to "1".
The CNC waits for the electrical cabinet to execute the requested M function
and return the "M-DONE" signal by setting this input high (24V).

Outputs M01 / Coolant Pin 3
This output besides providing the value of bit 1 of the selected decoded M function
of the table, acts as output for the COOLANT.
When using this option, be careful not to use this bit for both functions since the CNC
will activate it in both cases.
However, the CNC maintains this output active as long as the coolant is selected even
when executing an M function which would deactivate this output.
WORK Pin 21
The CNC activates this OUTPUT on CNC power-up and it deactivates only when
accessing the tool table (by the operator) or the auxiliary modes (with OEM password).
This output becomes active again when returning to the standard work mode.

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
On the back of the CENTRAL UNIT of the 800T CNC there is a three-prong connector
to be connected to AC power and to ground..
The AC power must be supplied via an independent 110VA shielded transformer with an
output voltage between 100V AC and 240V AC +10% and -15%.
The power outlet for the equipment must be near it and with easy access to it.
In the case of a power surge or voltage overload it is recommended to wait for about 3
minutes before connecting it back in order to avoid any damage to the power supply.
The MONITOR of the 800T CNC must be connected to 220V AC.
2.1.1
INTERNAL POWER SUPPLY
Inside the CENTRAL UNIT there is a power supply that provides the different required
voltages.
Besides the two outside fuses for AC input protection (one per line), it has an inside 5A. fuse
for protection against overvoltage.

GENERAL CONSIDERATIONS
The machine tool must have all interference generating elements decoupled (relay coils,
contactors, motors, etc.).
* DC relay coils.
1N4000 type diodes.
* AC relay coils.
RC connected as close to the coils as possible with approximate values such as:
R 220 Ohm/1W
C 0,2 µF/600V
* A.C Motors.
RC connected between phases with values:
R 300 Ohm/6W
C 0,47µF/600V
Ground connection.
A proper ground connection in an electrical installation is essential in order to achieve:
*
The protection of people against electrical discharges caused by any malfunction.
*
The protection of electronic equipment against interference generated at the machine
itself or by other electronic equipment near by which could cause erratic malfunctioning
of the equipment.
Thus, all metallic parts must be connected to the same point and this, in turn, to ground. It
is essential to establish one or two main points in the installation where the elements
mentioned above will be connected.
Cables with sufficient section must be used in order to obtain an impedance as low as
possible and an effective interference suppression maintaining all installation components
at the same voltage level with respect to ground.

Chapter: 2
Section:
MACHINE AND POWER INTERFACE
MACHINE INTERFACE
Besides the proper grounding of the installation, the signal cables must be shielded and
twisted-pairs for greater necessary protection. The shield must be connected to a specific
point avoiding ground loops which could cause undesirable effects. This grounding of the
shield is done at the CNC’s ground terminal.
Each element of the machine-tool/CNC installation must be connected to ground through
the established main ground points. They will be conveniently set at a point close to the
machine-tool itself and properly connected to the Main Ground Point.
When a second ground point is required, it is recommended to join both points by a cable
with a section of 8 mm2 or greater (or two 4 mm2).
It must be verified that the resistance measured between each connector housing and ground
is less than 1 Ohm.

SET-UP
2.3.1
GENERAL CONSIDERATIONS
Inspect the whole electrical cabinet verifying the ground connections BEFORE powering
it.
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 power supply used for the digital inputs and outputs of the PLC 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 dip-switches for each feedback device are set properly according to the type
of feedback signals being used.
Verify that the E-STOP button is pressed.

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 to all the axes and the spindle.
It does NOT imply the emergency output.
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/O 1.
This output will be normally high or low depending on the setting of machine parameter
P604(4). High if P604(4) = 1, low if P604(4) = 0.
These 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.

2.5 ACTIVATION / DEACTIVATION OF EXTERNAL DEVICES
With this CNC it is possible to activate and deactivate up to 4 external devices including the
coolant. The other devices depend on the type of machine available.
To do this, the following four keys are available:
All these keys have a lamp to indicate whether the device is currently activated (lamp on)
or deactivated (lamp off)
If it is selected (lamp on) pin 3 of connector I/O2 stays high (24V).
When it is not selected, (lamp off) pin 3 of connector I/O2 stays low (0V)
When this device (O1) is selected, the CNC sends the M10 function out to activate
it and an M11 to deactivate it.
When this device (O2) is selected, the CNC sends the M12 function out to activate
it and an M13 to deactivate it.
When this device (O3) is selected, the CNC sends the M14 function out to activate
it and an M15 to deactivate it.
The coolant may be activated or deactivated at any time but the other devices (O1, O2 and
O3) must be activated or deactivated only when the axes of the machine are in position.

When selecting this option, it is possible to access the tool table or to calibrate the
tools.
3.4.1 TOOL TABLE
When selecting this option, the CNC shows the values assigned to each tool offset,
that is, the dimensions of each tool being used to machine the parts.
Once the tool offset table has been selected, the operator will be able to move the
cursor over the screen one line at a time by means of the up and down arrow keys.
Each tool offset has a series of fields defining the tool dimensions. These fields are:
*
Tool length along the X axis.
It will be given in radius and in the work units currently selected. Its value range
is:
X ±8,388.607 mm
*
or
X ±330.2599 inches.
Tool length along the Z axis.
It will be given in the work units currently selected. Its value range is:
Z ±8,388.607 mm
*
or
Z ±330.2599 inches.
Tool radius.
It will be given in the work units currently selected. Its maximum value is:
R 1000.000 mm
or
R 39.3700 inches.
The CNC will use this "R" value and the tool location code "F" (shape code)
when applying tool compensation on the finishing passes while machining the
programmed profile.
*
Type of tool (location code "F").
To indicate the type of tool being used, the CNC offers 10 different location
codes (F0 thru F9).
This factor depends on the shape of the tool being used and on the sides of the
cutter used to machine with.

To activate the BCD outputs "MST01" thru "MST80" (pins 20 thru 27 of connector
I/O 1) besides, the decoded ones, machine parameter "P606 bit 7" must be set to
"0".
Bit 16 of the bottom row indicates whether the "M" function is executed at the
beginning (0) of the block or at the end (1) once the programmed movements have
been executed
Bit 17 of the bottom row determines whether the CNC must wait for confirmation
from the electrical cabinet indicating that the execution of the M function has been
completed (M-done) or not before resuming the execution of the program.
This confirmation is carried out by means of the "M-DONE" input at pin 15 of
connector I/O 1. This bit may be set as follows:
0 The CNC waits for the "M-DONE" confirmation signal from the electrical
cabinet.
1 The CNC does not wait for the "M-DONE" confirmation signal from
the electrical cabinet.
Up to 32 M functions may be set. All those empty M-table positions are indicated
as M??.
Whenever a previously defined M function is redefined, the new setting replaces the
old one.

M FUNCTIONS SENT OUT IN BCD
The CNC generates a series of M functions to indicate to the electrical cabinet that
a certain event has taken place.
The CNC activates the BCD outputs corresponding to the generated "M" function
(pins 20 thru 27 of connector I/O 1).
If besides activating these BCD outputs, the decoded outputs are also to be activated
(pins 3 thru 13 and 22 thru 25 of connector I/O 2), the corresponding M functions
must be defined at the decoded M-function table.
The CNC generates the following M-functions in BCD:
M00 At the end of the execution of each step of the selected operation while in
"SINGLE" mode.
M03 When pressing the key to start the spindle clockwise.
M04 When pressing the key to start the spindle counter-clockwise.
M05 When pressing the key to stop the spindle.
M10 When pressing the key to turn on the external device O1.
M11 When pressing the key to turn off the external device O1.
M12 When pressing the key to turn on the external device O2.
M13 When pressing the key to turn off the external device O2.
M14 When pressing the key to turn on the external device O3.
M15 When pressing the key to turn off the external device O3.
M20 To indicate that the part execution has ended.
For example, on a machine with a bar feeder, the PLC could control the
machining of several parts in a row by using this function.
M30 When pressing the RESET key of the CNC.
M41 When selecting the first spindle speed range.
M42 When selecting the second spindle speed range.
M43 When selecting the third spindle speed range.

3.8.4 LEADSCREW ERROR COMPENSATION
To select this option, press [AUX], select the "Special Modes" option of the "Auxiliary
Modes" menu, key in the password (0101) and press the key corresponding to
"LEADSCREW ERROR COMPENSATION".
The CNC will display the Leadscrew Error Compensation table.
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:
[R] [P] [N] [ENTER].
There are up 30 parameter pairs for each axis. Parameters P0 thru P59 for the X axis
and P60 thru P119 for the Z axis.
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:
Odd parameter
±8388.607 millimeters
±330.2599 inches
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%.
Examples: If the distance between two consecutive points is 3 mm. the maximum
difference of their relevant error values can be 0.090 mm.
If the error difference between two consecutive points is the maximum
(0.127mm), the distance between them cannot be smaller than
4.233mm.

MACHINE PARAMETERS
Atention:
All unused machine parameters must be set to "0" to guarantee the proper
functioning of the 800T CNC.
It is recommended to save the machine parameters of the CNC at a peripheral

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 the access to the machine parameters, to the decoded M function
table and to the leadscrew error compensation table, proceed as follows:
*
Press [AUX] and after selecting the "Lock/Unlock" option of the of the "Auxiliary
Modes" menu...
*
Key in: "P1111" and press [ENTER] to lock the access or: "P0000" [ENTER]

4.3.1 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).
P604(3)

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.

ON) is being executed or when a "BEGIN-START", "END-START"
type command is being executed.
P606(7)
M function output also 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.

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.
“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.

4.3.4 TOOL PARAMETERS
P700 Number of tools
It is given by an integer between 0 and 32.
P900 X coordinate for the tool change position
P901 Z coordinate for the tool change position
When performing a tool change, it is recommended to use a position away from
the part to do it, especially when running repetitive parts.
This tool change position may be established by machine parameter "P900" for
the X axis coordinate and "P901" for the Z axis coordinate. Every time a tool has
to be changed, the machine will move to this position automatically.
Range or values:
± 8388.607 millimeters.
± 330.2599 inches.
Also, when calibrating a tool, the CNC will ignore the "P900" and "P901" position
values and the tool change will be done at the point where it is requested.
If parameters P900 and P901are set to "0", the CNC acts as follows:
* If while executing a part-program, a tool change is required, it will take place
at the starting point of the part-program execution.
* If the tool change is required while being in any other mode, the CNC will not
move the axes and the tool change will be carried out right where it was requested.
P617(3)

P730
Subroutine associated with the T function
The CNC takes this parameter into consideration when executing the ISO-coded
user program 99996.
It indicates the number of the standard (non-parametric) subroutine to be executed
by the CNC whenever a tool is selected in the execution of program 99996.
It is defined by an integer between 0 and 99. If set to "0", no associated subroutine
will be executed.
Atention:
If a subroutine is associated to the T function, nothing else must be
programmed after the T. Otherwise, the CNC will issue the corresponding
error message.
The subroutine is executed before the T function. That is, it executes
the subroutine first and, then, it assumes the new T.
The associated subroutine to the T function must be defined in one of
the special ISO-coded user programs, P99994 and P99996.
When setting "P730=0" and not using an automatic tool changer,
"P617(3)=0", the CNC displays the message: "TOOL CHANGE" (in
English for all languages) and interrupts program execution.

signal is activated to the instant the analog output is generated.
0 (NO) = There is no delay between the two signals
1 (YES) = 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).

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.
0 (NO) = The Enable signal disappears.
1 (YES) = The Enable signal is maintained (Continuous control).

With the Feed-forward gain, which is proportional to the feedrate, it is possible to
improve the positioning loop minimizing the amount of following error. However it
is not recommended when acceleration/deceleration ramps are not being used.
These parameters define the % of analog voltage due to the programmed feedrate. It
is given by an integer between 0 and 255.
The value which will be added to the following error is (Kf x F/6) where F is the
programmed feedrate and Kf is:
* The value of this parameter when using linear acc/dec.
For example, for the X axis: "Kf = P720"
* 1/8 of the value assigned to this parameter when using bell-shaped acc/dec.
For example, for the X axis: "Kf = P720/8"
The CNC will apply the proportional gain (K1 and K2) to the value resulting from the
addition of the following error plus the value selected by means of the feed-Forward
gain.
When the value resulting from the addition is smaller than the value assigned to the
gain break-point, the CNC will apply the following formula:
Analog = K1 x [Following error + (Kf x F/6)]
And when the value resulting from the addition is greater than the value of the gain
break-point:
Analog = (K1 x Ep) + {K2 x [Following error + (Kf x F/6) - Ep]}
Where "Ep" is the gain break-point value assigned to the corresponding parameter.

For example: P112 =10000 sets a homing feedrate of 100m/min. or

Examples to calculate resolution with P606(1)=1:
Example 1:
Resolution in “mm” with square-wave encoder
We want to obtain a 0.01mm resolution with a square-wave encoder mounted on the X axis whose
leadscrew has a 5mm/turn pitch.
Since the multiplying factor applied by the CNC may be either x2 or x4 (depending on machine
parameter setting). The resulting encoder line count will be:
Leadscrew pitch
Number of pulses =
Multiplying Factor x Resolution
For a factor of x4:
5 mm
Number of pulses =
= 125 pulses/rev.
4 x 0.01m
P103= 1 P602(3)=0 P106=0 P602(6)=0
For a factor of x2:
5mm
Number of pulses =
= 250 pulses/rev.
2 x 0.01 mm
P103= 1 P602(3)=0 P106=0 P602(6)=1
Resolution in “inches” with square-wave encoder
Example 2:
We would like to obtain a 0.001 inch resolution with a square-wave encoder mounted on to the X axis
which has a 4-pitch leadscrew (4 turns per inch or 0.25 inch/turn).
Since the CNC always applies a multiplying factor of either x2 or x4 (selected by machine parameter),
the required encoder line count (pulses per rev) in each case will be:
Leadscrew pitch
Number of pulses =
Multiplying factor x Resolution
With a x4 factor:
0.25
Number of pulses =
= 62.5* pulses/turn
4 x 0.001
* A gear reduction will be required to achieve this line count per turn.
P103= 1 P602(3)=1 P106=0 P602(6)=1
With a x2 factor:
0.25
Number of pulses =
= 125 pulses/turn
2 x 0.001

For example: P112 =10000 sets a homing feedrate of 1m/min. or
0.1 inch/min.
Examples to calculate resolution with P609(7)=1:
Example 1:
Resolution in “mm” with square-wave encoder
We want to obtain a 0.0001mm resolution with a square-wave encoder mounted on the X axis whose
leadscrew has a 5mm/turn pitch.
Since the multiplying factor applied by the CNC may be either x2 or x4 (depending on machine
parameter setting). The resulting encoder line count will be:
Leadscrew pitch
Number of pulses =
Multiplying Factor x Resolution
For a factor of x4:
5 mm
Number of pulses =
= 12500 pulses/rev.
4 x 0.0001m
P103= 1 P602(3)=0 P106=0 P602(6)=0
For a factor of x2:
5mm
Number of pulses =
= 25000 pulses/rev.
2 x 0.0001 mm
P103= 1 P602(3)=0 P106=0 P602(6)=1
Resolution in “inches” with square-wave encoder
Example 2:
We would like to obtain a 0.001 inch resolution with a square-wave encoder mounted on to the X axis
which has a 4-pitch leadscrew (4 turns per inch or 0.25 inch/turn).
Since the CNC always applies a multiplying factor of either x2 or x4 (selected by machine parameter),
the required encoder line count (pulses per rev) in each case will be:
Leadscrew pitch
Number of pulses =
Multiplying factor x Resolution
With a x4 factor:
0.25
Number of pulses =
= 6250 pulses/turn
4 x 0.00001
P103= 1 P602(3)=1 P106=0 P602(6)=1
With a x2 factor:
0.25
Number of pulses =
= 12500 pulses/turn
2 x 0.00001
P103= 1 P602(3)=1 P106=0 P602(6)=1

6.4 MACHINE PARAMETERS FOR SPINDLE CONTROL
It is necessary to have a spindle feedback encoder installed in order to perform the
following operations:
* Automatic threading operation
* Spindle orientation
When working with spindle orientation, the spindle must be in closed loop; in other
words, the CNC must be controlling the actual spindle speed at all times providing
the electrical cabinet with the analog voltage so the spindle turns at the selected
speed.
The section on "Spindle " in the chapter on "concepts" of this manual describes
how these parameters may be used.
P800
Number of pulses of the spindle encoder.
It indicates the number of pulses per revolution (line count) of the rotary encoder
for the spindle.
It is given by an integer between 0 and 9999.
If this parameter is set to "0", the CNC will assume that the spindle has no encoder.
P603(8)
Active monitoring of actual spindle speed.
Besides simply displaying the real spindle speed, it is also possible to have a
certain control over it as follows:
* When the real spindle speed is less than 50% of the programmed S speed, the
CNC generates an internal Feed-Hold in order to provide more time for the
spindle to reach that speed.
* When the real spindle speed is greater than 150% of the programmed S speed,
the CNC activates the emergency output and it issues the corresponding error
code.

M3 / M4 confirmation by detecting feedback direction reversal
It indicates whether or not the CNC waits for M3 / M4 confirmation by detecting
that the spindle feedback has changed direction when programming a reversal of
spindle direction (M3 to M4 or vice-versa).
0 = It does not wait for confirmation. It considers the command executed
instantaneously.

P707 In-position zone (dead band) for spindle orientation
It establishes the width of the in-position zone to both sides of the programmed
coordinate so the CNC considers the spindle to be in position.
It is expressed by the number of encoder pulses between 0 and 255.
Remember that the CNC internally multiplies by 4 the number of pulses provided
by the encoder.
Therefore, if the spindle encoder provides 1000 pulses per turn and P707 = 100,

7.1.1 COUNTING FREQUENCY LIMITS
Sine-wave signals
The maximum counting frequency for sine-wave feedback signals is 25KHz (25,000
pulses/sec.).
Therefore, the maximum feedrate for each linear axis will depend upon the selected
resolution (machine parameters "P103 and P303") and the period of the feedback
signal being used.
The maximum feedrate for each rotary axis will depend upon the number of pulses
per revolution.
Example 1:
When using a linear scale with a 20µm, the maximum feedrate for an axis with 1µm
resolution will be:
20 µm/pulse x 25,000 pulses/sec = 500 mm/sec = 30 m/min.
Square-wave signals
The maximum counting frequency for differential square-wave signals is
200 KHz (200,000 pulses/sec.), with a 450nsec. separation between flanks (that is 90º
±20º phase shift).
Therefore, the maximum feedrate for each linear axis will depend upon the selected
resolution (machine parameters "P103 and P303") and the period of the feedback
signal being used.
When using FAGOR linear scales, the maximum feedrate is limited by its own
characteristics to 60m/min (2362 inches/min).
When using FAGOR rotary encoders, the limitation is set by the maximum number
of pulses delivered by the encoder; which is 200KHz.

7.1.2 RESOLUTION OF X AND Z AXES
The CNC has a series of machine parameters to set the resolution of each axis.
The resolution used on each axis indicates the minimum variation distinguishable by the
feedback device. It is given in microns or 0.0001 inch units.
The machine parameters used to define the axis resolution are the following:
P103, P303
They set the counting resolution for each axis.
P602(3), P602(2)
They set the measuring units for each axis feedback signal (mm
or inches).
P106, P306
They set the type of feedback signal being used (square-wave or
sine-wave) for each axis.
P602(6), P602(5)
They indicate the multiplying factor, x2 or x4 to be applied to the
feedback signals of each axis.
P619(1), P619(2)
They indicate the special multiplying factor to be applied to the
sine-wave feedback signals of each axis (besides the normal x5).
Example 1:
Resolution in "mm" with square-wave encoder
We want to obtain a 2µm resolution with a square-wave encoder mounted on the X
axis whose leadscrew has a 5mm/turn pitch.
Since the multiplying factor applied by the CNC may be either x2 or x4 (depending
on machine parameter setting). The resulting encoder line count will be:
Leadscrew pitch
Number of pulses =
Multiplying Factor x Resolution
for a factor of x4:
5000 µm
Number of pulses =
= 625 pulses/rev.
4 x 2 µm
P103= 2 P602(3)=0 P106=0 P602(6)=0

Number of pulses =
= 1250 pulses/rev.

P103= 2 P602(3)=0 P106=0 P602(6)=1
Chapter: 7

CONCEPTS
FEEDBACK SYSTEMS

If a FAGOR encoder is chosen, its pulse output frequency is limited to 200KHz
(although the CNC admits square-wave pulses with a frequency of up to 200KHz).
Therefore, the maximum feedrate for this axis will be:
When using a x4 multiplying factor:
200,000 pulses/sec.
Max. Feed =
x 5 mm/rev. = 1600 mm/sec. = 96 m/min.
625 pulses/rev.
When using a x2 multiplying factor:
200,000 pulses/sec.
Max. Feed =
x 5 mm/rev. = 800 mm/sec. = 48 m/min.
1250 pulses/rev.
Example 2:
Resolution in "mm" with sine-wave encoder
We want to calculate the multiplying factor required to obtain a resolution of 2µm
with a sine-wave encoder mounted on to the X axis which has a 5mm/turn
leadscrew pitch.
Leadscrew pitch
Multiplying factor =
5000 µm
=
number of pulses x Resolution
= 10
250 x 2 µm
Since the CNC always applies a x5 multiplying factor to the sine-wave feedback
signals, we will need an extra x2 factor. Thus:
P103= 2 P602(3)=0 P106=1 P602(6)=1 P619(1)=0
Even when choosing a FAGOR encoder which outputs up to 200KHz, the actual
usable frequency is this time limited by the CNC to 25KHz for sine-wave signals.
Therefore, the maximum feedrate for this example will be:
25,000 pulses/sec.
Max. Feed =
x 5 mm/rev. = 500 mm/sec. = 30 m/min.
250 pulses/rev.

Chapter: 7
Section:
CONCEPTS
FEEDBACK SYSTEMS
Example 3:
Resolution in "mm" with square-wave linear scale
Considering that the CNC applies either a x2 or x4 multiplying factor (set by machine
parameter), a linear scale must be chosen whose pitch is 2 or 4 times the desired
resolution.
When using FAGOR linear transducers (scales) with 20µm pitch, the following
resolutions may be obtained: 5µm (20/4), 10µm (20/2).
Thus:
Scale pitch
20µm

P103 P602(3)

10
P106 P602(6)

Since the counting frequency of the CNC is limited to 200KHz for square-wave
signals, the maximum feedrate obtainable with a 20µm-pitch scale is:
Max. Feed = 20 µm/pulse x 200,000 pulses/sec. = 4000 mm/sec. = 240 m/min.
However, if FAGOR linear scales are used, the maximum feedrate is limited (by
the scales) to 30m/min. (1181 inches/min.)
Example 4:
Resolution in "mm" with sine-wave linear scales
A sine-wave linear scale is being used with a 20µm pitch and 1µm resolution.
We need to calculate the multiplying factor required for the desired resolution.
Scale pitch
Multiplying factor =
20 µm
=
Resolution
= 20
1 µm
Since the CNC always applies a x5 factor to sine-wave feedback signals, we will need
an additional x4 factor. Therefore:
P103= 1 P602(3)=0 P106=1 P602(6)=0 P619(1)=0
Since the counting frequency is limited (by the CNC) to 25KHz for sine-wave signals,
the maximum feedrate for this axis will be:
Max. Feed = 20 µm/pulse x 25,000 pulses/sec. = 500 mm/sec. = 30 m/min.
However, if FAGOR linear scales are used, the maximum feedrate is limited (by
the scales) to 60m/min. (2362 inches/min.)

We would like to obtain a 0.0001 inch resolution with a square-wave encoder

0.25 inch/turn).
Since the CNC always applies a multiplying factor of either x2 or x4 (selected by
machine parameter), the required encoder line count (pulses per rev) in each case will
be:
Leadscrew pitch
Number of pulses =

With a x4 factor:

Example 6: Resolution in "inches" with sine-wave encoder
We would like to obtain a 0.0001 inch resolution with a 250-line sine-wave encoder on

We must calculate the multiplying factor required for that resolution:

7.2 ADJUSTMENT OF X AND Z AXES
In order to carry out this adjustment, it is necessary to have the feedback devices connected
to the CNC.
Before starting this adjustment of the axes it is a good idea to move each one of them to
the center of its travel and set the mechanical travel limits (stops), controlled by the
electrical cabinet, near that center point in order to avoid possible collisions.
Verify that the axes are not under CONTINUOUS CONTROL (machine parameters
P105 and P305 must be set to "N"). This means that once the axis is in position, its
enable signal to the servo drive is deactivated.
Also, verify that machine parameters P104 and P304 are set to "Y" indicating that there
must be a delay between the activation of the axis enable signal and the output of its analog
voltage.
Once these parameter settings have been verified, proceed with the axis adjustment as
follows:
*
The axes will be adjusted one at a time.
*
Connect the power output of the servo drive corresponding to the axis to be adjusted.
*
Jog the axis being adjusted by using the jog keys.
If the axis runs away, the CNC will issue a Following Error message. Change the
setting of the machine parameter for the sign of the analog voltage (P100 for the X axis
and P300 for the Z axis) and press RESET to assume the new value.
*
If the axis does no longer run away, but it does not count in the desired direction,
modify the setting of the parameter corresponding to the COUNTING DIRECTION
(P101 for X and P301 for Z) as well as the value of the parameter corresponding to
the SIGN OF THE ANALOG VOLTAGE (P100 for X and P300 for Z). Press RESET
to assume the new values.
*
If the counting direction is correct, but it jogs in the wrong direction, change the setting
of the machine parameter corresponding to the JOGGING DIRECTION (P102 for X
and P302 for Z).

7.2.1 OFFSET AND MAXIMUM FEEDRATE ADJUSTMENT
These adjustments will be made on the axis servo drives and on the spindle drive.
Offset adjustment
This adjustment will be carried out in two steps:
Pre-adjustment of the drive offset
* Disconnect the analog input and short-circuit it with a wire jumper.
* Turn the offset potentiometer of the drive until the output voltage of the tacho
reads 0V. This voltage should be measured with a volt-meter set on the 200mV
DC scale.
* Remove the wire jumper of the analog input.
Critical drive-offset Adjustment
* Execute a program in the "point-to-point movement" mode
which moves
the axis continuously back and forth. A sample program for the Z axis may be the
following:
P0 X0 Z100
P1 X0 Z-100
P2 X0 Z100
P3 X0 Z-100
...........
...........
P19 X0 Z-100
P20 X0 Z100
While the axis is moving back and forth, monitor the amounts of following error
of the axis in both directions and make them the same by turning the offset
potentiometer of the drive. Not at the CNC.
Maximum feedrate adjustment
It is recommended to adjust the servo drives in such a way that the maximum speed
is obtained with 9.5V of analog voltage.
Also, this maximum axis speed (feedrate) must be assigned to the corresponding
machine parameter (P111 for X and P311 for Z).
The calculation of the axis maximum feedrate depends on the maximum rpm of the
axis motor, the gear reduction and the type of leadscrew being used.
Chapter: 7
Section:
CONCEPTS
ADJUSTMENT X, Z AXES
Page
9
Example for the Z axis:
Having a motor whose maximum rpm is 3000 and the pitch of the leadscrew is
5mm/revolution.
Maximum feedrate = r.p.m. of leadscrew x leadscrew pitch
P311 = 3000 r.p.m. x 5mm/rev. = 15000 mm/minute
Once these values are assigned to the corresponding parameters, it is recommended
to proceed with the adjustment of the drive.
To do this, execute a program in the "point-to-point movement" mode
which moves the axis continuously back and forth. A sample program for the Z
axis may be the following:
P0 X0 Z100
P1 X0 Z-100
P2 X0 Z100
P3 X0 Z-100
...........
...........
P19 X0 Z-100
P20 X0 Z100
Before running this program, assign to machine parameter P310 the value of P311
and select "F0" as active feedrate. The
key lamp must be OFF.
While the axis is moving, set the analog voltage going into the servo drive to 9.5V by
turning the gain potentiometer of the drive and NOT at the CNC.

7.2.2 GAIN ADJUSTMENT FOR X AND Z AXES
It is necessary to properly adjust the different gains for each axis in order to optimize the
response of the whole system to the programmed movements.
It is recommended to use an oscilloscope in order to obtain a finer adjustment of the axes
by monitoring the signals provided by the tacho or the analog voltage in case the system
becomes somewhat unstable.
The CNC has a series of machine parameters which permit adjusting the proportional gain
for each axis. These parameters are:
*
PROPORTIONAL GAIN K1. Set by machine parameters P114 and P314.
*
PROPORTIONAL GAIN K2. Set by machine parameters P116 and P316.
*
GAIN BREAK-POINT value. Set by machine parameters P115 and P315.

ADJUSTMENT X, Z AXES

7.2.2.1 PROPORTIONAL GAIN ADJUSTMENT
The analog voltage supplied by the CNC to control the axis is, at all times, a function of
the amount of following error; that is, the difference between the theoretical position and
the real (actual) position of the axis.
2.5mV
Analog output = Proportional gain x following error (microns) x
64
On start-up and slow-down, the following error of the axis is very small. Therefore, the
proportional gain must be great in order for the axis to respond properly.
On the other hand, once the axis reaches its programmed speed, the following error is
maintained practically constant and it is necessary to apply a smaller gain in order to keep
the system stable.
The FAGOR 800T CNC offers two proportional gains K1 and K2 to better adjust the
system as well as another parameter referred to as Gain Break-point which defines the
active area for each one of these gains.
The CNC applies the proportional gain K1 whenever the amount of following error for the
axis is smaller than the value assigned to the machine parameter corresponding to the gain
break-point.
When the amount of following error exceeds the gain break-point value, the CNC applies
the K2 value.
Analog = (K1 x Ep) + [K2 x (Following error - Ep)]
Where "Ep" is the value assigned to the gain break-point and it is given in microns
Page
12
Chapter: 7
Section:
CONCEPTS
ADJUSTMENT X, Z AXES
When adjusting the proportional gain, it must be borne in mind that:
*
When the amount of following error exceeds 32mm (1.2598 inches) the CNC will
issue a Following error message for the corresponding axis.
*
The amount of following error will decrease as the gain value increases, but the system
will tend to be more unstable.
*
In practice, most machines seem to respond well to what is called a unity gain (or gain
of 1) which represents a following error of 1mm at a feedrate of 1m/minute or a
following error of 0.001 inch at a feedrate of 1 inch/min.
Therefore, this could be used as a practical starting point for the gain calculation
described next. After analyzing the behavior of the machine for this gain, its value
may be changed in order to optimize it.

7.2.2.2 CALCULATION OF K1, K2 AND GAIN BREAK-POINT
The value K1 represents the analog voltage corresponding to 1 micron of following error.
It is given by an integer between 0 and 255.
Analog (mV) = K1 x Following error x Kcnc
Where: In metric: Following error in microns and Kcnc = 0.039
In inches: Following error in thousandths of an inch and Kcnc = 0.993
The amount of following error corresponding to the GAIN BREAK-POINT is given in
microns or in ten-thousandths of an inch by parameter P115 for the X axis and P315 for
the Z axis. It is recommended to set it to a value slightly greater than the following error
corresponding to the maximum machining feedrate F (P110 and P310) (not positioning
feedrate, G00: P111 and P311).
The machine parameter for K2 gain sets the analog voltage for 1 micron of following error
being applied from the gain break-point on.
It is also given by an integer between 0 and 255 and it is typically set to a value between
50% and 70% of K1 in order to avoid abrupt analog voltage changes when switching to
slow machining feedrates.
METRIC example for K1 and gain break-point:
The maximum positioning feedrate (G00) for the Z axis (P311) is 15m/min. the
maximum machining feedrate (programmable F) is to be limited to 3m/min and the
desired following error for 1m/min is 1 micron (unity gain). The servo drive has been
adjusted to obtain 15m/min at 9.5V.
Thus, the analog voltage corresponding to 1m/min would be:
Analog =
9500mV
-------------- x 1m/min = 633mV
15m/min
And the K1 value corresponding to a gain of 1 would be:
Analog (for 1m/min)
K1 = ---------------------------------F.E. (for 1m/min) x Kcnc
633mV
= ------------------------------------ = 16.2048
1000 microns x 0.039
The integer value to be assigned to K1 could be 16.
If K1 has been set for a gain of 1 (K1=16 for this example) and the maximum
machining feedrate (F) is 3000 mm/min (P310). At this feedrate, the following error
should be about 3000 microns. Thus, the gain break-point value should be slightly
larger than 3000 microns; for example: P315 = 3100 microns.
Thus: P310=3000; P311=15000; P314=16; P315=3100; P316=50% - 70% of K1
Example in INCHES for K1 and gain break point:
The maximum positioning feedrate (G00) for the Z axis (P311) is 600 inches/min. the
maximum machining feedrate (programmable F) is to be limited to 120 inches/min
and the desired system gain (Kv) should be equal to one (unity gain). The servo drive
has been adjusted to obtain 600 inches/min at 9.5V.
Page

Chapter: 7
Section:
CONCEPTS
ADJUSTMENT X, Z AXES
The following error corresponding to 1 inch/min for this unity gain would be:
Following Error = FE =
Feedrate
1 inch/min
-------------------------- = ----------------- = 0.001"
Kvgain x 1000
1 x 1000
The analog voltage corresponding to 1 inch/min would be:
Analog =
9500mV
-------------- x 1"/min = 15.8333mV
600"/min
And the K1 value corresponding to a gain of 1 would be:
Analog (for 1"/min)
15.8333mV
K1 = ---------------------------------- = ------------------------------------ = 15.94
F.E. (for 1"/min) x Kcnc
1 (thousandth) x 0.993
The integer value to be assigned to K1 could be 16.
If K1 has been set for a gain of 1 (K1=16 for this example) and the maximum
machining feedrate (F) is 120 inch/min (P310). At this feedrate, the following error
should be about 0.1200 inches. Thus, the gain break-point value should be slightly
larger than 1200 ten-thousandths of an inch; for example: P315 = 1250.
Thus: P310=120; P311=600; P314=16; P315=1250; P316=50% - 70% of K1
To perform a practical axis adjustment at the machine:
it is recommended to first set K1 = K2 and run a program in "point-to-point
movement" mode
continuously moving the axis back and forth.
A program of this sort, for the Z axis, may be the following:
P0 X0 Z100
P1 X0 Z-100
P2 X0 Z100
P3 X0 Z-100
...........
...........
P19 X0 Z-100
P20 X0 Z100
Atention:
Once each axis has been adjusted separately. Both axes should be adjusted
together in such a way that their following errors for the same feedrate are the
same in order to achieve proper interpolations between both axes in the K1
area.
Watch the amount of following error reached at maximum machining feedrate and
assign that value or one slightly larger to the gain break-point.
Once K1 and the gain break-point have been set, change the value of K2 to one between
50% and 70% of K1.

7.3 REFERENCE POINTS FOR X AND Z AXES
A CNC machine must have the following reference points established:
*
Machine Reference Zero or origin point of the machine. It is set by the machine
manufacturer as the origin of the coordinate system of the machine.
*
Part Zero or origin point for the part. It is the origin point set to program the
measurements of the part. It can be chosen freely by the programmer and its reference
to the machine reference zero is set by means of a zero offset.
*
Machine Reference Point. It is the physical location of the marker pulse or reference
pulse (Io) used as home to synchronize the whole machine coordinate system. The
axis moves to this point when being "homed" and the CNC assumes the reference
values set at machine parameter "P119" or "P319" accordingly.

7.3.1 MACHINE REFERENCE SEARCH (HOME)
With this CNC it is possible to search home on each axis ([X] [up arrow] and [Z]
[up arrow]) as follows:
1.- The CNC starts moving the axis in the direction set by machine parameter P618(8)
for X and P618(7) for Z at the feedrate set by machine parameter P112 for X and P312
for Z until the home switch is pressed.
If the selected axis has no home switch (parameters "P600(5), P600(4)"), the CNC
will consider it to be pressed and it will go on with paragraph 2.
2.- Once the home switch is pressed, the CNC will continue moving the axis at the
feedrate selected by machine parameters P807 for X and P808 for Z until the reference
pulse (marker, Io) of the feedback device is found.
Once the home search is completed, the CNC will cancel the selected zero offset and it
will display the coordinates of the machine reference point indicated by machine
parameter P119 for X and P319 for Z.

7.3.2 CONSIDERATIONS
*
If at the instant the home search is initiated, the home switch is pressed, the axis will
withdraw (in the opposite direction to that set by “P618(8), P618(7)”) until releasing
the home switch before starting the actual home search.
*
If the axis is out of the soft travel limits (set by P107,P108 for X and P307,P308 for
Z), it has to be jogged into the work area (within limits) and, then, positioned at the
correct side from home before starting the actual home search.
*
Care must be taken when placing the home switch and when setting the home
searching feedrates (P112, P807 for X and P312, P808 for Z) to prevent any
overshooting.
*
Set machine parameter P600(7) for X and P600(6) for Z to indicate the type of marker
pulse (Io) being used.
FAGOR linear transducers (scales) have a negative marker pulse (Io) every 50 mm
(about 2 inches) and FAGOR rotary encoders output a positive marker pulse (Io) per
revolution.
*
The home switch will be mounted in such a way that the marker pulse "Io" is always
found in the area corresponding to the second home searching feedrate (set by P807
and P808).
*
If there is no room for that, the first home searching feedrate (set by P112 and P312)
must be reduced. This might be the case with those rotary encoders where the marker
pulses are very close to each other.

7.3.3 ADJUSTMENT OF THE VALUE CORRESPONDING TO THE
MACHINE REFERENCE POINT (HOME)
Before making this adjustment, place the mechanical travel limits (stops) where they are
supposed to go.
One of the procedures that can be followed is this:
1.- Define the machine parameters related to home.
Set P600(5) and P600(4) to 1 indicating that both axes have home switches.
Set parameters “P600(7)” and “P600(6)” indicating the type of marker pulse used by
the feedback device when searching home. Fagor scales have one negative marker
pulse (Io) every 50mm and Fagor rotary encoders have one positive marker pulse per
revolution.
Also, set parameters “P618(8)” and “P618(7)” to indicate the direction the axes must
move when searching home.
Besides, set parameters "P112" and "P312" to indicate the home switch approaching
feedrate (1st home searching feedrate) as well as parameters P807 and P808 to
indicate the marker pulse approaching feedrate (2nd home searching feedrate).
Assign a value of "0" to the machine reference point. Parameters P119 and P319.
2.- Position the axis in the proper area for home search and execute the home search
command.
Press [X] or [Z] and then, [up arrow] followed by
The CNC will carry out the home search and when done, it will assign a value of zero
to that point.
3.- Move the axis to the physical location where machine zero point will be (or to a
position whose distance to machine zero is known), write down the position value
displayed by the CNC at that point.
The value to be assigned to parameter P119 or P319 will be:
Machine coordinate of the measured point - CNC value at that point.
Example for the Z axis:
If the point of known dimensions is 230mm from the machine zero and the CNC
shows "-123.5mm", the value to be assigned to P319 will be:
“P319” = 230 - (-123.5) = 353.5 mm.
4.- Assign this new value to the machine parameter and press
or power the
CNC down and back up in order for the CNC to assume this new value.
5.- Perform a new home search in order for the CNC to assume the correct reference
values.

7.3.4 AXIS SOFTWARE TRAVEL LIMITS
Once the home search has been done on all the axes, proceed with the setting of the
software travel limits for each axis.
This procedure is to be done one axis at a time and can be done as follows:
*
Move the axis in the positive direction up to a point close to the mechanical stop
keeping a safety distance from it.
*
Assign to P107 or P307 (as it corresponds) the position value displayed by the CNC
for that point.
*
Repeat those two actions in the negative direction and assigned the new displayed
value to parameter P108 or P308 (as it corresponds).
*
Once this procedure is completed for all the axes, press [RESET] or power the CNC
down and back up in order for the new values to be assumed by the CNC.

7.4 ACCELERATION/DECELERATION
In order to avoid abrupt start-ups and slow-downs of the axes, this CNC offers two ACC./
DEC. control systems.
One of them, acts only on linear interpolations while the other one acts on all types of
movements.
It is possible to use the Feed-forward gain in either case in order to improve the positioning
loop of the axes, thus minimizing the amount of following error. This gain must be used
only when working with ACC/DEC. control.
7.4.1 CALCULATION OF FEED-FORWARD GAIN
The feed-Forward gain is proportional to the feedrate and is set by machine parameters
P720 and P721 which indicate the % of analog voltage that is due to the programmed
feedrate.
The value added to the following error is (Kf x F/6) where Kf is the value of Feed-Forward
selected by machine parameter and F is the programmed feedrate.
The CNC will apply the proportional gain (K1 and K2) to the value resulting from adding
the following error of the machine plus the value selected by the feed-Forward.
When the result of the addition is smaller than the value of the gain break-point, the CNC
will apply the formula:
Analog voltage = K1 x [Following error + (Kf x F/6)]
And when the result of the addition is greater than the value of the gain break-point, the
CNC will apply the formula:
Analog voltage = (K1 x Ep) + {K2 x [Following error + (Kf x F/6) - Ep]}
Where "Ep" is the value of the gain break-point.

7.4.2 ACCELERATION/DECELERATION ON LINEAR INTERPOLATIONS
When working with this type of acceleration, it is necessary to define by parameters P712
and P713 the acceleration period or time required by each axis to reach the positioning
feedrate (indicated by parameters P111 and P311).
This time is also valid for the deceleration ramp.
When performing a linear interpolation, the CNC applies to the resulting path the greater
of the two acc/dec periods assigned to the axes involved in such interpolation.
It is also possible to apply this type of acc./dec. on all linear interpolations when
"P609(4)=1" or only when those movements are carried out at the maximum programmable
feedrate (set by parameter P110) when P609(4)=0.
On the other hand, when no acc/dec. is to be applied on G05 block transitions, parameter
P616(6) must be set to "1".
7.4.3 ACCELERATION/DECELERATION ON ALL TYPES OF
MOVEMENTS
This type of acc./dec. is used on high speed machines.
It is activated by setting parameter P621(8) to "1". This cancels the other type of
acc./dec. described earlier.
When working with type of acc./dec., it is necessary to define by parameter P731 the ramp
period or time required by an axis to reach the selected feedrate (acceleration). This time
is the same for the deceleration ramp and common to all the axes.

HANDWHEEL MOVEMENTS
The axes may be moved from the CNC, by means of mechanical handwheels or by means
of electronic handwheels.
The available options are:
* The machine only has mechanical handwheels. With this option, no electronic
handwheels can be used.
* The machine has one electronic handwheel. With this option, no mechanical handwheels
can be used.
* The machine has two electronic handwheels, one for each axis. With this option no
mechanical handwheels can be used
7.5.1 THE MACHINE HAS MECHANICAL HANDWHEELS
The following machine parameters must be set:
P621(7)=0
P105=0
P305=0
The machine has mechanical handwheels
The X axis is not continuously controlled when in position
The Z axis is not continuously controlled when in position
This way, when the axes reach position their enables are cancelled so they can be moved
by means of the mechanical handwheels.
7.5.2 THE MACHINE HAS A SINGLE ELECTRONIC HANDWHEEL
When the machine has an electronic handwheel, no mechanical handhweel can be used.
When using a FAGOR 100P handwheel, both axes may be governed one at a time. To do
this, press the axis selector button on the back of the handwheel as described later on.
Machine parameters P105 and P305 must be set to "1 (YES)", so there is continuous
control of the axes. This means that once an axis is in position, its enable signal remains
on. (the CNC holds them in position)
Besides, the following parameters must be properly set:
P621(7)=1
P622(3)=1
P609(1)=1

To move the axes with the electronic handwheel, select the
positions on the
Feedrate Override Switch. The available positions are 1, 10 and 100 which indicate the
multiplying factor being applied to the pulses supplied by the electronic handwheel.
Then, press any JOG key corresponding to the axis to be moved. The CNC will highlight
the selected axis. If only one single electronic handwheel is used and it is a FAGOR 100P
model, the desired axis can also be selected by pressing the button on the back of the
handwheel.
Turn the electronic handwheel. The distance the axis will move depends on the position
selected at the Feedrate Override Switch and the values assigned to the corresponding
machine parameters.
Example:
The machine parameters for the electronic handwheel have been set as follows:
P602(1) = 0
P501
=1
P602(4) = 0
Millimeters
Resolution 0.001 mm.
x4
The Feedrate Override switch is at position "x100".
The selected axis will move 0.001mm x4 x100 = 0.4 mm for each pulse received.
When turning the electronic handwheel very fast, the CNC may be forced to move the axis
faster than the maximum allowed feedrate (parameters P111 and P311). In this case, the
CNC will limit its speed to the maximum feedrate allowed, ignoring the additional pulses
and, therefore, avoiding the possible following error messages that otherwise would have
been issued.
To select another axis, just press any of the JOG keys corresponding to the other axis. The
CNC will now highlight the new selected axis. If only one single electronic handwheel is
used and it is a FAGOR 100P model, the desired axis can also be selected by pressing the
button on the back of the handwheel.
To quit this operating mode (with electronic handwheel), select any other position of the
Feedrate Override Switch. When using a FAGOR 100P handwheel, this mode can also be
quit by holding the axis selector button on its back for a few seconds.
Whenever the Feed-hold input is active (pin 15 of connector I/O 1) or one of the software
travel limits (set by parameters P107, P108, P307 and P308) has been overrun, the CNC
will ignore the electronic handwheel and, therefore, will not move the machine. It will
have to be moved by means of the mechanical handwheels.
The handwheel will also be ignored when a CNC error occurs (emergency, etc.).

7.5.3 THE MACHINE HAS TWO ELECTRONIC HANDWHEELS
When having two electronic handwheels, it will not be possible to use the mechanical
handwheels of the machine at the same time. They may be used only when the CNC is
turned into a DRO by activating its manual input (pin 19 of connector I/O 1) which will
deactivate the electronic handwheels. Each electronic handwheel controls only one axis;
therefore, the axis selector button of the FAGOR 100P handwheel will have no effect.
The first handwheel will control the X axis and the second one will be associated with the
Z axis.
Machine parameters P105 and P305 must be set to "1" (YES), indicating that when the axis
is in position its enable signal is maintained.
Besides, the following parameters must be properly set:
P609(1)=0
The first electronic handwheel is not working as a FAGOR
100P model.
P621(7)=1
The machine has no mechanical handwheels
P500, P621(6)
Counting direction of the electronic handwheels (1st and 2nd).
P602(1), P621(3) Measuring units of the electronic handwheel feedback signals
(1st and 2nd).
P501, P621(1,2) Counting resolution of the electronic handwheels (1st and
2nd).
P602(4), P621(5) Multiplying factor for electronic handwheel feedback signals
(1st and 2nd).
The axes can be moved in all FOS (feedrate override switch) positions and the CNC will
apply the corresponding multiplying factor indicated at the handwheel positions and a
"x1" factor for any of the other FOS positions.
The distance the axis will move depends on the position selected at the Feedrate Override
Switch (FOS) and the values assigned to the corresponding machine parameters.
Example for the 1st handwheel:
The machine parameters for the electronic handwheel have been set as follows:
P602(1) = 0
P501
=1
P602(4) = 0

The Feedrate Override switch is at position "x100".
The selected axis will move 0.001mm x4 x100 = 0.4 mm for each pulse received.

When turning the electronic handwheel very fast, the CNC may be forced to move the axis
faster than the maximum allowed feedrate (parameters P111 and P311). In this case, the
CNC will limit its speed to the maximum feedrate allowed, ignoring the additional pulses
and, therefore, avoiding the possible following error messages that otherwise would have
been issued.
Atention:
Even when the Feed-hold input is active (pin 15 of connector I/O 1) or one
of the software travel limits (set by parameters P107, P108, P307 and P308)
has been overrun, the CNC will be governed by the electronic handwheel
and, therefore, it will move the machine.
The handwheel will be ignored when a CNC error occurs (emergency, etc.)
and when a part or cycle is being executed.

7.6 SPINDLE
Depending on the setting of machine parameters P601(3) and P601(2), the CNC provides
one of the following spindle speed outputs:
* Analog voltage (±10V) via pins 36 and 37 of connector I/O1.
* 2-digit BCD coded output via pins 20 thru 27 of connector I/O1.
* 4-digit BCD coded output via pins 20 thru 27 of connector I/O1.
Analog voltage
To use the CNC's analog voltage for the spindle drive, set P601(3) and P601(2) to "0".
The CNC will generate the analog voltage corresponding to the programmed spindle
speed within ±10V.
When a unipolar analog voltage is desired (either 0 to +10V or 0 to -10V), machine
parameter P607(4) must be set to "1". The sign of this analog voltage will be set by
machine parameter P601(4).
When the machine has an automatic spindle range changer, machine parameter
P601(1) must be set to "1". Then, whenever a new spindle speed is selected which
involves a range change, the CNC will automatically generate the M function
associated with the new spindle speed range M41, M42, M43 or M44.
BCD Output
When desiring a BCD coded output for spindle speed control, machine parameters
P601(3) and P601(2) must be set as follows:
For 2-digit BCD outputP601(3)=1 and P601(2)=0
For 4-digit BCD outputP601(3)=0 and P601(2)=1
The CNC will issue the code corresponding to the programmed spindle speed at the
BCD outputs (pins 20 thru 27 of I/O 1).
It will also activate the "S Strobe" output to indicate to the electrical cabinet that the
required auxiliary function must be executed and it will wait for the "M-DONE"
signal from the electrical cabinet in order to consider the data transfer has concluded.
When using a 2-digit BCD code, P601(3)=1 and P601(2)=0, The CNC will indicate
the selected spindle speed according to the following conversion table:

7.6.1 SPINDLE SPEED RANGE CHANGE
With this CNC, the machine can have a gear box in order to adapt the speeds and torques
of the spindle motor to the various machining requirements.
Up to 4 spindle ranges may be set by means of machine parameters P7, P8, P9 and P10
specifying the maximum spindle rpm value for each one of them.
The value assigned to P7 must correspond to the lowest range (RANGE 1) and the one
assigned to P10 to the highest range (RANGE 4).
When not using all 4 ranges, start the speed assignment from the lowest range up and set
the unused ranges to the highest speed being used.
7.6.1.1 MANUAL SPINDLE RANGE CHANGE
To be able to perform the spindle speed range change manually, machine parameter
P601(1) must be set to "0".
When the new selected spindle speed involves a range change, the CNC will display a
message indicating the range to be selected.
Once this range has been selected, press [ENTER] for the CNC to output the new spindle
analog voltage.
Then, the CNC will automatically generate the M function associated with the new spindle
range: M41, M42, M43 or M44.

Chapter: 7
Section:
CONCEPTS
SPINDLE
7.6.1.2 AUTOMATIC SPINDLE RANGE CHANGE
To be able to automatically change the spindle speed range, machine parameter
P601(1) must be set to "1".
When the new spindle speed selected requires a range change, the CNC will execute
the auxiliary M function corresponding to the new range.
The CNC uses the auxiliary functions: M41, M42, M43 and M44 to indicate to the
electrical cabinet which range must be selected: RANGE 1, RANGE 2, RANGE 3 or
RANGE 4).
Also, in order to facilitate the range change, the CNC offers the possibility to use a
residual analog output during a range change. Machine parameter for the spindle:
P601(6).
The value of this residual analog voltage is defined by machine parameter P701 and
the oscillation period for this residual analog voltage is set by machine parameter
P702.
The automatic range change is carried out as follows:
1.- Once the range change is detected, the CNC outputs the BCD value of the
corresponding M function: M41, M42, M43 or M44, via pins 20 thru 27 of
connector I/O 1.
50 milliseconds later, it activates the "M Strobe" output to indicate to the
electrical cabinet to execute the required M function. This signal is maintained
active for 100 milliseconds.
2.- When the electrical cabinet detects the "M Strobe" signal, must deactivate the "MDONE" input of the CNC to "tell" it that the execution of the corresponding M
function has begun.
3.- The electrical cabinet will execute the required M function using the BCD outputs of
the CNC (pins 20 thru 27 of connector I/O 1).
Chapter: 7
Section:
CONCEPTS
SPINDLE
Page
31
4.- After keeping the BCD outputs active for 200 milliseconds, the CNC will output the
residual analog output indicated by parameter P701 if so established by parameter
P601(6).
The oscillation period for this residual analog voltage is determined by machine
parameter P702.
5.- Once the range change is completed, the electrical cabinet must activate the M-DONE
input of the CNC to "tell" it that the requested M function has been executed.
When the electrical cabinet has some device needing the BCD and "M Strobe" signals
from the CNC active for a longer period of time, machine parameter P602(7) must be set
"1" (the CNC waits for the down flank of the M-Done signal).

* Automatic threading operation.
* Spindle orientation.
The machine parameters to be set are:
P800
P606(3)
Number of pulses (line count) of the spindle encoder.
Counting direction of the spindle.
Also, to work with "spindle orientation", the following parameters must be set:
P601(4)

P600(8)
P706
P707
P708

Spindle proportional gain in spindle orientation.
Minimum spindle analog output in spindle orientation.
To orient the spindle, key in the following keystroke sequence:
*
[S]
, the bottom of the screen will display: "S POS =".
*
Key in the desired orientation angle value. for example: S20 or S35.006
*
press
.
Every time the spindle is being oriented after working in open loop (in regular rpm mode),
the CNC will slow down the spindle speed below the value indicated by parameter P706
(if it was turning); it will home it (search for the marker pulse of the spindle encoder) and
it will finally position (orient) it to the specified angle (S POS=).
This spindle position will be displayed in whole degrees and in large characters as:
S320 °
The spindle will only be homed prior to being oriented whenever it is switched from
operating in open loop to doing it in closed loop (orientation).
When changing back from closed loop to open loop, the display will show the spindle rpm
by replacing the "°" symbol with "RPM" characters.
The spindle will switch to open loop when pressing
gency or on power-up.

P901
P617(3)
Number of tools
X coordinate for tool change position
Z coordinate for tool change position

7.7.1 MACHINE WITH AN AUTOMATIC TOOL CHANGER
To select a new tool, press [TOOL] followed by the tool number and press
The CNC informs the electrical cabinet of the selected tool number via the BCD outputs
(pins 20 thru 27 of I/O 1) and it activates the "T Strobe" output to "tell" the electrical
cabinet that it must change the tool.
Once the tool change is completed, the CNC assumes the values assigned to the tool offset
of the same number and it applies those values (tool length and radius) in all the operations
performed with this new tool.
7.7.2 MACHINE WITHOUT AN AUTOMATIC TOOL CHANGER
The CNC must know at all times which tool is being used in a machining operation.
To do this, every time a new tool is selected and changed, press [TOOL] followed by
the new tool number and press
The CNC assumes the values assigned to the tool offset of the same number and it applies
those values (tool length and radius) in all the operations performed with this new tool.
If while executing a cycle or part previously programmed, a tool must be selected, the
CNC will display a message indicating the number of the new tool which must be selected.
It also interrupts the execution of the program until the operator changes the tool and
presses [ENTER].

Section:
CONCEPTS
TOOLS
7.7.3 TOOL CHANGE POSITION
It is recommended to use a location away from the workpiece to perform the tool change,
especially when making repetitive parts.
With this CNC, it is possible to establish this location by means of machine parameters
P900 and P901. These parameter values are absolute X and Z coordinates referred to
Machine Reference Zero (home) and the axes will move to this position for a tool change.
This way, every time the operator requests a new tool or the CNC itself needs to change
the tool to execute a cycle or a programmed part, the axes will move to this tool change
position indicated by parameters P900 and P901.
If both parameters are set to "0", the CNC will act as follows:
*
When the operator requests a tool change, the CNC will not move the axes and the tool
change will take place at the current position of the axes.
*
To execute a programmed cycle with another tool, the CNC will change the tool
before starting to execute it, right where the cycle was called upon
*
During the execution of a part, the CNC assumes as tool change position the starting
point of the part execution. Therefore, whenever a tool change is required, the CNC
will move the axes to that point.
The CNC will ignore the values indicated in parameters P900 and P901 when calibrating
a tool and it will change tools where the change has been requested.

7.8 FEED-HOLD AND M-DONE SIGNAL PROCESSING
The CNC has one single input (pin 15 of connector I/O 1) to process both signals.
This input must be normally high and these signals are processed as follows:
FEED HOLD
This signal may interrupt the execution of a block.
If while the axes are moving, this input is set low, the CNC maintains the spindle
rotating and stops the axes by bringing their analog voltages to "0V" and keeping their
enable signals on.
When this input is set back high, the CNC resumes the movement of the axes.
M-DONE or CONFIRMATION FROM ELECTRICAL CABINET
This signal is used as confirmation from the electrical cabinet that the execution of the
requested M, S or T function has been completed.
When the CNC sends to the electrical cabinet the BCD output signals corresponding
to the M, S or T function, the electrical cabinet must set this M-DONE input low.
The CNC will wait for the electrical cabinet to finish the execution of such function
and set this M-DONE input back high. This will "tell" the CNC that the execution of
the corresponding auxiliary function has been completed.

7.9 M, S, T FUNCTION TRANSFER
M function transfer:
When sending the auxiliary M functions to the electrical cabinet, the CNC uses the
BCD outputs (pins 20 thru 27 of connector I/O 1) and it activates the "M Strobe"
output to "tell" the electrical cabinet to execute them.
Depending on how they are defined on the table, the CNC must wait or not for the "MDONE" signal to consider it executed.
If an M function is executed which is not defined on the M function table, the CNC
will wait for the "M-DONE" signal before resuming the execution of the program.
S function transfer (BCD format):
When a new spindle speed (S) is programmed, the CNC issues the corresponding
BCD code (via pins 20 thru 27 of connector I/O 1) and it activates the "S Strobe"
output to "tell" the electrical cabinet to execute it.
The CNC will wait for the "M-DONE" signal to consider it executed.
If the new selected "S" involves a range change, the CNC executes first the M
functions corresponding to the range change and then, it transfers the new selected
spindle speed.
T function transfer:
When selecting a new tool "T", the CNC issues the corresponding BCD code (via pins
20 thru 27 of I/O 1) and it will activate the "T Strobe" to "tell" the electrical cabinet
to execute it.
The CNC will wait for the "M-DONE" signal to consider it executed.

7.9.1 M, S, T FUNCTION TRANSFER USING THE M-DONE SIGNAL
When parameter P602(7) is set to "0", the CNC maintains the BCD outputs and the
corresponding Strobe signal (M, S, T) active for 100 milliseconds.
When the electrical cabinet has a device requiring the BCD signals to be active for a longer
time, machine parameter P602(7) must be set to "1".
In each case, the CNC acts as follows:
“P602(7)=0”
1.- The CNC transfers the BCD value of the selected function via pins 20 thru 27 of
connector I/O 1.
50 milliseconds later, the "M Strobe" output is activated to "tell" the electrical cabinet
to execute the M function.
2.- When the electrical cabinet detects the activation of the "M Strobe" signal, it must start
the execution of the corresponding function.
3.- The CNC will maintain the "M Strobe" signal for 100 milliseconds and the BCD
signals for another 50 milliseconds.
After this time period, it will wait for the M-DONE signal provided by the electrical
cabinet indicating to the CNC that the executiong of the "M" function is completed.

TRANSFER
“P602(7)=1”
This type of transfer is used when the electrical cabinet has a device which requires
the BCD outputs from the CNC to be active for a longer period of time.
1.- The CNC sends the BCD value of the selected function via pins 20 thru 27 of
connector I/O 1.
50 milliseconds later, it activates the corresponding Strobe output to "tell" the
electrical cabinet to execute the required auxiliary function.
2.- When the electrical cabinet detects the activation of one of the Strobe signals, it
must begin the execution of the corresponding function deactivating the
M-DONE signal to let the CNC know that this M function execution has begun.
Once the data from the CNC is read and processed, the electrical cabinet
deactivates the M-DONE input to "tell" the CNC that the execution of the
corresponding function has begun.
3.- The CNC will maintain the Strobe signal for another 100 milliseconds and the
BCD outputs for another 150 milliseconds.
After this time period, it will wait for the electrical cabinet to reactivate the
M-DONE input "telling" the CNC that the processing of the required function has
concluded.

7.9.2 M FUNCTION TRANSFER WITHOUT M-DONE SIGNAL
This type of transfer is done when the corresponding M function is defined on the decoded
M function table and its 17th bit is set in such a way that the CNC does not wait for the
M-DONE signal for the execution of the M function to be considered completed.
1.- The CNC transfers the BCD value of the selected function via pins 20 thru 27 of
connector I/O 1.
50 milliseconds later, the "M Strobe" output is activated to "tell" the electrical cabinet
to execute the M function.
2.- When the electrical cabinet detects the activation of the "M Strobe" signal, it must start
the execution of the corresponding function.
3.- The CNC will maintain the "M Strobe" signal for another 100 milliseconds and the
BCD signals for another 150 milliseconds.
After this time period, it will resume the execution of the program regardless of
whether the function has been completely executed or not by the electrical cabinet.

MAINTENANCE
Cleaning:
The accumulated dirt inside the unit may act as a screen preventing the proper dissipation of the
heat generated by the internal circuitry which could result in a harmful overheating of the CNC
and, consequently, possible malfunctions.
On the other hand, accumulated dirt can sometimes act as an electrical conductor and shortcircuit
the internal circuitry, especially under high humidity conditions.
To clean the operator panel and the monitor, a smooth cloth should be used which has been
dipped into de-ionized water and /or non abrasive dish-washer soap (liquid, never powder) or
75º alcohol.
Do not use highly compressed air to clean the unit because it could generate electrostatic
discharges.
The plastics used on the front panel of the CNC are resistant to :
1.- Grease and mineral oils
2.- Bases and bleach
3.- Dissolved detergents
4.- Alcohol
Avoid the action of solvents such as Chlorine hydrocarbons , Benzole , Esters
and Ether which can damage the plastics used to make the unit’s front panel.
Preventive Inspection:
If the CNC does not turn on when actuating the start-up switch, verify that the monitor fuse as
well as that of the power supply module of the Central Unit are in good condition and that they
are the right ones.
The Central Unit has two 3,15Amp./250V fast fuses (F), one per AC line.
See the label on the Monitor since it depends on the model.
21
To check the fuses, first disconnect the power to the CNC.
Do not manipulate inside this unit.
Only personnel authorized by Fagor Automation may manipulate inside
this module.
Do not manipulate the connectors with the unit connected to main AC
power.
Before manipulating these connectors, make sure that the unit is not
connected to main AC power.
Note :
Fagor Automation shall not be held responsible for any material or
physical damage derived from the violation of these basic safety
requirements.

> Too many nesting levels.
020
More than one spindle range have been defined in the same block.
021
This error will be issued in the following cases:
> There is no block at the address defined by the parameter assigned to F18, F19, F20, F21, F22.
> The corresponding axis has not been defined in the addressed block
022
An axis is repeated when programming G74.
023
K has not been programmed after G04.
025
Error in a definition block or subroutine call, or when defining either conditional or unconditional jumps.
026
This error is issued in the following cases:
> Memory overflow.
> Not enough free tape or CNC memory to store the part-program.
027
I//K has not been defined for a circular interpolation or thread.
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.
033
A movement of over 8388 mm or 330.26 inches has been programmed.
Example:
Being the Z axis position Z-5000, if we want to move it to point Z5000, the CNC will issue error
33 when programming the block N10 Z5000 since the programmed move will be:
Z5000 - Z-5000 = 10000 mm.
In order to make this move without issuing this error, it must be carried out in two stages as
indicated below:
N10 Z0
N10 Z5000
; 5000 mm move
; 5000 mm move
034
S or F value too large.
035
Not enough information for corner rounding, chamfering or compensation.
036
Repeated subroutine.
037
Function M19 programmed incorrectly.
038
Function G72 programmed incorrectly.
It must be borne in mind that if G72 is applied only to one axis, this axis must be positioned at part zero (0
value) at the time the scaling factor is applied.
039
This error occurs in the following cases:
> More than 15 nesting levels when calling subroutines.
> A block has been programmed which contains a jump to itself. Example: N120 G25 N120.
040
The programmed arc does not go through the defined end point (tolerance 0.01mm) or there is no arc that goes
through the points defined by G08 or G09.
041
This error is issued when programming a tangential entry as in the following cases:
> There is no room to perform the tangential entry. A clearance of twice the rounding radius or greater 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

The memory contents will be kept for 10 more days (with the CNC off) from the moment this error occurs.
The whole battery module located on the back must be replaced. Consult with the Technical Service
Department.
Atention:
Due to danger of explosion or combustion: do not try to recharge the battery, do not expose it to
temperatures higher than 100°C (232°F) and do not short the battery leads.
064 * External emergency input (pin 14 of connector I/O1) is activated.
065 * This error comes up if, while probing (G75), the programmed position is reached without receiving the probe
signal.
066 * X axis travel limit overrun.
It is generated either because the machine is beyond limit or because a block has been programmed which
would force the machine to go beyond limits.
068 * Z axis travel limit overrun.
It is generated either because the machine is beyond limit or because a block has been programmed which
would force the machine to go beyond limits.
070 ** X axis following error.

> A block number has more than 4 characters.
> Strange characters in memory.
106 ** Inside temperature limit exceeded.
108 ** Error in Z axis leadscrew error compensation parameters.
110 ** Error in X axis leadscrew error compensation parameters.
111 * FAGOR LAN line error. Hardware installed incorrectly.
112 * FAGOR LAN error. It comes up in the following instances:
> When the configuration of the LAN nodes is incorrect.
> The LAN configuration has been changed. One of the nodes is no longer present (active).
When this error occurs, access the LAN mode, editing or monitoring, before executing a program block.
113 * FAGOR LAN error. A node is not ready to work in the LAN. For example:
> The PLC64 program is not compiled.
>A G52 type block has been sent to an 82CNC while it was in execution.
114 *
FAGOR LAN error. An incorrect command has been sent out to a node.
115 * Watch-dog error in the periodic module.
This error occurs when the periodic module takes longer than 5 milliseconds.
116 * Watch-dog error in the main module.
This error occurs when the main module takes longer than half the time indicated in machine parameter
"P729".
117 * The internal CNC information requested by activating marks M1901 thru M1949 is not available.
118 * An attempt has been made to modify an unavailable internal CNC variable by means of marks M1950 thru
M1964.
119
Error when writing machine parameters, the decoded M function table and the leadscrew error compensation
tables into the EEPROM memory.
This error may occur when after locking the machine parameters, the decoded M function table and the
leadscrew error compensation tables, one tries to save this information into the EEPROM memory.
120
Checksum error when recovering (restoring) the machine parameters, the decoded M function table and
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.
