1.1 Front panel
Each axis display has eight 14.1mm high LEDs and another one for the minus
sign (-).
Description of LED's and keys:
ABS It stays on when operating in absolute mode and off when in incremental
mode. To access it or quit it, press this key.
Φ It stays on when operating in diameter mode. In this mode, the DRO displays
twice the actual axis movement. To access it or quit it, use this key if allowed
by installation parameter PAR04.
INCH It stays on when working in inches and off when doing it in millimeters. To
access it or quit it, press this key.
To get into and out of home search mode.
Selection of the current tool.
There are 20 tools that may be set for the part when using absolute
coordinates. The possible reference points (datum points) are from 0 to 19.
The 20i-T model shows the active reference on the display at all times,
whereas the 30i-T model only shows it when it is selected, after pressing the
reference key.
To select the axis or preset it with a certain value.
To zero the axis when the "quick zeroing" mode has been activated (see

1.2 Turning the unit on and off
It turns on automatically when applying voltage or after 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 unit from mains, press this key so it saves 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.

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 sequence accesses parameter PAR53. The first digit
corresponds to the number of decimals to be displayed in mm and the second
digit in inches.
Radius / Diameter
When these models are used for measuring radii or diameters, one can
display twice the real displacement of the axis (diameter) by pressing this key.
The Φled will turn on or off to indicate the double or actual reading

2.2 Incremental, absolute and with respect to Machine Reference Zero
This DRO shows the current position of two or three axes (20i-T / 30i-T).
Coordinate means the distance from one point or position with respect with
another chosen as reference.
These DRO's can show the position of the axes in incremental or absolute
mode.
•In Home mode, it displays the distance from the current position of the axis
to the home point chosen in the feedback system.
Press this sequence to access the Home mode (only to search home).
(ABS) •In Absolute (ABS), when the 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.
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, press one of these two sequences.

2.2.1 Example
In incremental
mode:
Using the lower figure, let us imagine we wish to make a part in which three
holes have to be drilled with the coordinates stated. It is clear that the
blueprint will only reflect the incremental coordinates (I) or the absolute ones
(ABS) referring to the part zero (point "0" in the figure) although the DRO also
shows them with respect to home (Io).
After referencing the axes, as was described in the previous section, we can
make this part in incremental or absolute mode according to whether we
chose a type of dimensions (I) or (ABS) of the blue-print.

-Press this key until the ABS LED is turned off.
-Move the axis up to the face of the part to set it as part zero.
At this point, one can proceed in two ways:
-Preset the axis with a zero value by pressing this keystroke sequence:
-Move the axis towards the first position until the DRO reads: 22.600.
or...
-Preset the axis with a value of 22.600 by pressing this keystroke sequence.
In case of a mistake, press this key to cancel it and leave it as it was.
Pressing this key displays the previous preset value.
- Move the axis towards the first position until the DRO reads: 0.000.
This last method turns out to be more practical as after selecting the
destination coordinate one only has to remember to move the axis until the
DRO reads zero.

- Once this turning operation has concluded, one can go to the next position,
after having preset the next coordinate (25.000), by moving the axis until the
display reads 0.000.
- And so on until all the turning operations are concluded.
By pressing this key until the ABS LED lights up, the DRO will show the real
position of the axis with respect to part zero "0"
-Press this key until the ABS LED is turned on.
-To preset part zero:
-Place the axis exactly over “0” and press:
At any time, by pressing this key, the DRO will display the present position
with respect with the previous zero (ABS led on).

2.3 Machine Reference selection and search
Although it is not absolutely necessary, it is recommended to use the
reference marks (Io) of the feedback system in order to set a machine zero
point.
This allows the user to reference the machine axes and restore 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 search. Once the reference mark has been found, mark
this area with a marker or sticker in order to carry out the home search in the
same area in later 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 depending 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 been homed.
Select the axis to be referenced (homed)
The selected axis blinks until a reference mark is detected. The reference
signal presets the axis display automatically 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 Operation with tools
2.4.1 Tool Preset
Up to 20 tools may be preset on this DRO model (from "tool 0" to "tool 19").
The unit stores in its internal memory the relative offsets of all the tools with
respect to that of "T0".
Therefore, if "T0" has been preset in ABS mode (on X and Z) and, then, the
rest of the tools, it will suffice to just preset "T0" again (on Z) to make a new
part. The DRO will then automatically recalculate all the offsets of the rest of
the tools without having to preset them for each part.
To preset a tool, just follow this procedure:
ABS
Notes: The presets done with any tool in incremental mode change the part zero for
- Place a part of known diameter in the chuck in absolute mode (ABS led on).
- Move the tool to be preset until it touches the part.
- Press this key. The 3rd display shows the word "tool" followed by the
number of the active tool.
- Enter the tool number.
- Press [ENTER] to validate this operation or [C] to cancel it.
- Preset the part diameter.
These tool presets are kept in memory even when the unit is powered off up
to a maximum of 10 years.

If a tool offset has been preset in Z

The tool offsets are referred to the machine zero found at the time. When
turning the DRO on, it is necessary to find the same reference mark.
The calculator function can also be used to preset an axis with the result of
the calculation. See section 2.5.5 Calculator.
