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.

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.

2.5 Special operations
2.5.1 Scaling factor
It is possible to apply a scaling factor within ±9.999 for mold making
applications:
[factor]
The DRO will then show the axis position resulting from multiplying its real
position by the 'value' of the scaling factor.
2.5.2 To access the special functions (Hold, taper calculation, calculator)
Pressing [F] accesses the "special functions" menu.
This key may be used to display the various available options.
Pressing [ENTER] assumes the selected option.
Options: 1 - HOLD
2 - Angle calculation
3 - Calculator
Note:
A function may be directly accessed by pressing [F] and then the function
number. That is, [F] [1] to access HOLD directly or [F] [2] for angle
calculation.
2.5.3 Coordinate freeze (HOLD).
It enables “freezing” the display of the counter whilst inside it goes on reading
the real position of the axis. This comes about when it is necessary to change
the tool and preset the dimension of the new one.
Tool preset in HOLD mode.
It is possible to preset on the X axis the actual diameter value of the machined
part (measured with caliper or micrometer).
Procedure:
Having selected a tool:
• Machine the part to any diameter.
• Without removing the tool, set the X axis in HOLD mode.
• Remove the tool and measure the resulting diameter.
Value
• Preset the part diameter. That value will be preset as the offset of the
selected tool.
• Exit the HOLD mode.

Page 12
Tool change at any known point of the part:
α
- Touch the part with the tool.
- Go into HOLD mode. The reading for that axis freezes with the current
value.
- Remove the tool to be replaced and insert the new one.
- Approach the new tool to the “freezing” point and touch the part at that point.
- Press this key. The reading “unfreezes” and starts counting from the
previously “frozen” value.
If this key is pressed instead, the DRO will assume half the distance traveled
since [HOLD] was pressed. This is possible when "freezing" only one axis.
2.5.4 Taper (cone) calculation
This DRO calculates the taper angle (cone) of a part by simply touching two of
its points and using these keys.
To do this, follow this procedure:
- Move the tool until it touches the part at any point of the taper.
- Access the angle calculation mode.
- Touch the part with the tool at any other point of the taper.
- Press [ENTER] so the DRO calculates the angle or [C] to cancel the
operation.
The "X" axis display will show the angle in ten-thousandths of a degree
(0.0001º) and the "Z" axis display will do so in degrees, minutes and
seconds.
- Press any key to return to the regular display mode.

proper dissipation of the heat generated by the internal electronic circuits with
the consequent danger of overheating and DRO fault.
Accumulated dirt can also, in some cases, provide a conductive path for
electricity which could give rise to faults in the internal circuits of the
equipment, especially in high humidity conditions.
To clean the equipment nonabrasive dish-washing detergents are
recommended (in liquid, never powder form) or 75% isotropic alcohol with a
clean cloth. DO NOT USE aggressive solvents, (benzol, acetones, etc.)
which could damage the materials the equipment is made with.
Do not use high pressure compressed air to clean the item as this could give
rise to an accumulation of charges which in turn lead to electrostatic
discharges.
The plastics used in the front panel of the DRO stand up to:
• Grease and mineral oils.
• Alkalis and bleaches.
• Dissolved Detergents.
• Alcohol
Avoid the effect of solvents such as Chlorohydrocarbons, Benzol, Esters and
Ethers because these could damage the plastics with which the front of the
equipment is made.
If the DRO does not come on press the rear switch for starting, make sure it is
properly connected and being supplied with the proper mains voltage.
