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.
V1911 - 30iE - Installation/Operation - (5/48)
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 sequence accesses parameter 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/Diameters
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  led will turn on or off to indicate the double or actual reading
respectively.
Notes: - This works in this way if bit 2 of installation parameter 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 operator can eliminate this oscillation by selecting the
"hysteresis" mode or the "minimum coordinate" mode just by pressing this
keystroke sequence to toggle from one mode to the other.
Note: To have this option available, installation parameters PAR20 and PAR25
must be set accordingly.
Part references (datum points)
There are 20 references or datum points that may be set for the part when
using absolute coordinates. The possible reference points (datum points) are
from 0 to 19. The 20i-M model shows the active reference on the display at all
times, whereas the 30i-M model only shows it when it is selected, after
pressing the reference key.
Selects the current reference. It will show the text "Select ref".
[Ref number]
Key in the desired reference number and press [ENTER].
V1911 - 30iE - Installation/Operation - (6/48)
2.2 Incremental, absolute and with respect to Machine Reference Zero
A coordinate DRO displays the present coordinate of one or several axes.
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 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 for a particular axis, press one of these
sequences:
V1911 - 30iE - Installation/Operation - (7/48)
2.2.1
Sample
We will drill the holes of the following part as moving examples in incremental
and absolute modes.
First, set the datum point on the part to be machined as described in the
section "Datum point (part zero) to work with tool compensation" on page 12.
The axis must be positioned without tool compensation (canceled) because
the hole coordinates are referred to the center and no tool radius
compensation is needed.

The calculator function can also be used to preset an axis with the result of
the calculation. See section 2.7.3 Calculator.
V1911 - 30iE - Installation/Operation - (9/48)
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 found the references (home).
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 Operating with tools
It is possible to define a tool and later compensate for its dimensions while
machining.
2.4.1
Entering tool dimensions
The Y axis blinks waiting for the tool value to be entered.
20i-M.- It requests the tool diameter.
30i-M.- It requests the diameter on the Y axis and the length on the Z axis.
[Value]
Enter this value pressing this keystroke sequence.
Note: Since only the diameter of a tool may be stored, when changing a tool, its
dimensions must be entered again.
2.4.2
Tool dimension compensation while machining
To properly machine the part, the tool diameter must be compensated
depending on the machining direction.
Tool This led turns on when activating any of the compensations.
Cancels tool compensation and turns the Tool led off.
V1911 - 30iE - Installation/Operation - (11/48)
2.4.3

In the example of the figure, the sequence would be:
For the X axis, move the tool and touch it on the left side and press this key.
To preset this side to 0. See note.
For the Y axis, move the tool and touch it on the lower side and press this key.
To preset this side to 0. See note.
Notes: If installation parameter PAR11=1, just press the axis key, [X] [Y] or [Z], to
zero it.
The tool diameter value must be previous entered in order to set the datum
(zero) point correctly.

PAR45 (for output O6); to access them directly:
The dro displays must be on, reading mode and press the following keys:
CODE: 060496 The X axis display shows the word "COdE". 060496
The displays of the DRO show PAR00.
Once in regular display mode, parameters PAR40 through PAR45 (output
levels) may also be recalled by pressing this keystroke sequence, so the work
mode may be changed without having to go through all the previous steps.
2.5.1.2 Deactivate the outputs:
Deactivates the digital outputs. The screen will blink the text “OUTS OFF”.
See parameter 65 to activate this function.
V1911 - 30iE - Installation/Operation - (14/48)
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 reading to zero pressing for an axis [CLEAR] [X] for one axis or
[CLEAR] [Y] for the other one.
- 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] for the other. The DRO
will display half of the distance covered by the tool.
- Retract the axes until the displays read 0.0000, the tool can be placed
exactly at the center of the part.
2.6 Examples of how to operate with tool compensation
The following illustration displays the typical application of tool compensation
to make both an inside and outside pocket.
Tool compensation is applied by pressing either [6], [4], [8] or [2] and
canceled by pressing [5].
After presetting the tool diameter, as was described in the previous section, it
is advisable to know how to apply the compensation before making said
movement.

2.7.2
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.
Example: To change a tool at any known point of the part:
- Touch the part with the tool.
- Go into HOLD mode. The reading for that axis freezes with the current
value.
- Select the axis.
- 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.

If any message other than the first two from the table were to come up, the
equipment should be switched off and on again until one of the first two are
seen.
After pressing this key to access the counting mode, check the parameters.
If any of the errors shown as (Service Department) are often repeated, ask
Fagor Automation's Customer Services Department about this.
If the display of any axis shows all its dots; for example: 1.4.3.6.5.7.2.5. means
that the axis has moved at a greater speed than what is required for its reading
(>200 kHz or 60 m/min with 1 µm resolution). This error will be displayed if the
alarm activation parameter for the axis PAR08(1)=1.
To clear the display, press this key.
If the axis value is flashing, this means that one of the travel limits established
by machine parameter has been exceeded. This error will be displayed if the
alarm activation parameter for the axis PAR08(2)=1.
If the DRO does not come on or goes out while running, check that the
voltage and ground outlets are as they should be. If there are OK, disconnect
the feedback connectors one by one. If the dro comes on, it means a
feedback failure. If the fault persists get in touch with Fagor Automation’s
Customer Services Department about it.

4.4 Maintenance
Cleaning: An accumulation of dirt in the equipment can act as a screen preventing
proper dissipation of the heat generated by the internal electronic circuits with
the consequent danger of overheating and DRO fault.
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 unit, we recommend to use non-abrasive dishwasher detergent
(gel, never powder) or isotropic alcohol at 75% with a clean cloth. DO NOT
USE aggressive solvents, (benzol, acetones, etc.) which could damage the
materials the equipment is made with.
Never use air compressed at high pressure to clean the unit because it could
cause the accumulation of electrostatic charges that could result in
electrostatic shocks.
The plastics used in the front panel of the DRO stand up to:
• Grease and mineral oils.
• Bases and bleach.
• 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.
Preventive inspection
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.
