1.2 Turning the unit on and off
It turns on automatically when applying vo ltage or afte r pressing the on /off
key.
It shows Fagor dro or the corresponding error code. See the error table and
PAR11 for more options.
Turns the DRO on or off.
Precautions
Before disconnecting this un it from mains, press this key so it sa ves the
current position.
If the unit is turned off or there is a power outage, the DRO will try to save the
current position. If it does not have enough time to safe all the data, it will
display ERROR 2 when turned back on.

2 DRO operation
2.1 Display modes
MM / INCH conversion
To display the position of the axes either in millimeters or inches by pressing
this key depending on whether the INCH led is off or on respectively.
Fine / coarse resolution
To turn off the last decimal digit (coarse resolution) for cases in which fine
resolution is excessive, simply by pressing this key.
Number of decimals
This keystroke seq uence accesses pa rameter PAR53. The first digit
corresponds to the number of decimals to be displayed in mm and the second
digit in inches.
Decimal degrees / Degrees.Minutes.Seconds
This key toggles the display format for the rotary axis [PAR00(4)=1] between
decimal degrees and Degrees.Minutes.Seconds.
Radius / Diameter
When these mode ls are used for measurin g radii or dia meters, one can
display twice the real displacement of the axis (diameter) by pressing this key.
The Φled will t urn on or off to indicate the double or actual reading
respectively.
Notes: - This works in th is way if bit 2 of installation para meter PAR04
(radius/diameter) of the axis has been preset as “1” (commutated).
Hysteresis or minimum position value
When carrying out certain operations such as drilling hard material, EDM, etc.
the position display may fluctuate annoyingly.
In these cases, the operato r can eliminate this oscillation by selecting the
"hysteresis" mode or the "minimum coo rdinate" mode just by p ressing this
keystroke sequence to toggle from one mode to the other.
Note: To have this option available, installation parameters PAR2 0 and PAR25
must be set accordingly.
Minimum, Maximum, Difference (10iE only)
To toggle between the following display modes: Min, Max, Dif and Normal.
Min. It displays the minimum position reached by the axis.
Max. It displays the maximum position reached by the axis.
Dif. It displays the difference between the maximum and the minimum position.
Normal. It displays the current position of the axis.

(6/35) - DRO operation - Installation/Operation - 10iE-20iE - (Soft: 01.xx)
2.2 Incremental, absolute and with respect to Machine Reference Zero
A coordinate DRO displays the present coordinate of one (10iE)
or two axes (20iE).
Coordinate means the distance from one point or position with respect with
another chosen as reference.
These DROs can display the position of the axes in incremental or absolute
mode or referring to home.
The next figure shows the different position display modes:
•In Home mode, it displays the distance from the current position of the axis
to the home point chosen in the feedback system (linear or encoder).
Press this sequence to access the Home Search mode.
(ABS) •In Absolute (ABS), when th e ABS led is on , it displays the distance from
the present position of the axis to part zero (D).
(I) •In Incremental, when the ABS and "home" LEDs are off the distance from
the present position of the axis to the previous position is displayed.
Toggles between the ABS and incremental modes.
On the 20iE model, it could occur that the installation parameter PAR11(1)
has been set to “0” for this key to independently affect each axis so that one
axis can display its position in incremental mode while the other does this in
absolute. In this case, to change the display mode for a particular axis, press
one of these two sequences.

(Soft: 01.xx) - 10iE-20iE - Installation/Operation - DRO operation - (7/35)
2.3 Machine Reference selection and search
Although it is not absolutely necessary, it is recommende d to use the
reference marks (Io) of the feedback system in ord er to set a machine zero
point.
This allows th e user to refe rence the mach ine axes and re store the work
coordinates after having turned the dro off, moved the machine while the dro
was off, for safety or for any other reason.
Fagor linear encoders have reference marks every 50 mm all along its length.
In order to use these marks properly, choose an area on the axis, for example
in the middle of the measuring length or at one end. Approach this area and
carry out the home sea rch. Once the reference mark has be en found, mark
this area with a marker or sticker in order to carry out the home search in the
same area in la ter occasions and make sure that you are using the same
machine zero point (home).
Fagor also offers encoders with distance-coded reference marks every 20, 40
or 100 mm. When using these distance-coded reference marks, there is no
need to move to the 0 position to find the references, simply move a distance
equal to the gap between marks (20, 40 or 100 mm depe nding on the linear
encoder)
When using an absolute encoder, there is no need to search for the reference
marks (home).
The dro stores in its internal memory work coordinates such as machine zero,
absolute and incremental.
2.3.1 Home search sequence
For encoders with regular reference marks, move the axis to the home area.
Access or exit the home search mode.
The axis displays blink showing " r " if the axis has not been homed or
" r on" if it has found the references (home).
Select the axis to be referenced (homed)
The selected axis blinks until a reference mark is de tected. The reference
signal presets the axis display au tomatically with the value of PAR10, 0.000
mm by default.
If the encoder does not have a reference mark, move the axis to the desired
position and press this key.

2.4 Operating with tools
It is possible to define a tool and later compensate for its length while
machining.
2.4.1 Entering tool length
The Y axis blinks waiting for the tool value to be entered.
It requests the tool length.
Enter this value pressing this keystroke sequence.
Note: Since only the length of a tool may be stored, when changing a tool, its length
must be entered again.
2.4.2 Absolute and incremental mode
We will drill the holes of the following part as moving examples in incremental
and absolute modes.

2.5 Special operations
2.5.1 Scaling factor
It is possible to apply a scaling fact or within ±9.999 for mold making
applications:
The DRO will th en show the axis position resulting from multiplying its real
position by the 'value' of the scaling factor.
2.5.2 Part centering
Note: This feature is available when none of the axes have installation
parameter PAR04(2)=1 (radius/diameter commutable).
Part centering can be done as follows:
- Set the dro in absolute mode.
- Touch one side of the part with the tool.
- Set the readin g to zero pressing for an axis [ CLEAR] [X] for one axis or
[CLEAR] [Y/Z] for the other one (20iE).
- Take the tool to the other side of the part and touch this with it.
- Press the sequence [1/2] [X] for one axis or [1/2] [Y/Z] for the other (20iE).
The DRO will display half of the distance covered by the tool.
- Retract the axes until the displays read 0.000 0, the tool can be placed
exactly at the center of the part.

3.5 Easy setup
The "Easy Setup" may be used to set up the feedback of the DRO and to
verify that the installation is correct and no feedback pulses are missed.
It sets up the encoder resolu tion and the kind of reference marks being used
as well as the positive counting (reading) direction.
3.5.1 Accessing the "Easy Setup" mode
Press [CLEAR] [OFF]
And, instead of entering the parameters accessing code, key in: 555
The axes displays will show “Setup” meaning that the feedback is not set up
yet.
CODE: 555

(20/35) - DRO installation - Installation/Operation - 10iE-20iE - (Soft: 01.xx)
3.5.2 Operating mode.
• Move the axis to the origin or zero point and press the axis key.
The display shows “START”.
• Move the axis in the positive direction all the way to the end of the travel so
the DRO can read as many reference marks as possible.
•Press [ENTER] to finish. The moving direction used will be assumed as the
positive direction.
The axis status will then switch to one of the following:
Ready Correct feedback setup
Repeat Wrong feedback setup, the process should be repeated.
Error Error in the feedback system.
Note: If the feedback device is a steel tape t ype linear encoder, press [F] before
pressing [ENTER] so it is properly detected.
3.5.3 Power and machine connection
Always mount it vertically so its keyboard is within operator's reach and its
digits are easily visible (at operator's eye level).
Do not connect or disconnect the DRO connectors while it is under power.
Connect all metallic parts to a common point on the machine tool and it to the
general ground point. Use cables of enough gage (no thinner than 8 mm 2 )
for this connection.
3.6 Installation parameters
These DROs have a number of insta llation parameters to configure it for a
particular application.
The way th ese parameters are displayed depends on whether they are
general or particular for each axis.
• If it affects the axes, the parameter number (PAR??) appears on each axis
display and the corresponding axis key must be pressed to modify it.
• If it is a general parameter and there are more than one axis (20iE, 20iE-B) ,
the X display will show the parameter number and the Y its current value; if
there is only one axis, its numb er will appea r on the X displa y and, after
pressing this key, its value.
There are several kinds of parameters depending on how to set them:
• With binary values, it only takes values of 0 or 1 for each digit. The value is
changed by pressing the key with the relevant digit between [1] and [8].
Where [1] corresponds to the rightmost digit o f the display a nd [8] to the
leftmost digit.
• Numeric values, usually with the corresponding axis reso lution, they are
entered as regular coordinate preset.
