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.

(4/32) - DRO description - Installation/Operation - 20i-T / 30i-T - V0612

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.

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 Φ 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).

Z axis as a single axis or combination of both (Z

1

and Z

2

). Only at the 30i-T:

To display the Z axis position, one or two feedback devices may be used. One for the cross slide (Z

1

)and the other one for the carriage (Z

2

).

When using two feedback devices, the "Z" axis display may show the position of Z

1 axes.

, that of Z

2

or the result from combining (adding) the positions of both

The rightmost digit of the third display shows a "1", a "2" or is off to indicate that the Z axis display (2nd one) corresponds to "Z

1

", "Z

2

" or to the combination of "Z

1

+Z

2

" respectively. This selection rotates by pressing this key. It also shows the text "tool" followed by the number of the active tool corresponding to the XZ coordinates shown on the other displays.

Axis feedrate. Only at the 30i-T:

The third axis (Zs) display shows the feedrate of the fastest moving axis in m/min or feet/min depending on the status of the "inch" LED. To activate or cancel this option, see PAR11 in the installation manual.

V0612 - 20i-T / 30i-T - Installation/Operation - DRO operation - (5/32)

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.

(6/32) - DRO operation - Installation/Operation - 20i-T / 30i-T - V0612

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.

15.000

25.000

22.600

-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:

[22.600

[22.600] -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.

[0.000] - 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.

ABS

[0.000] - 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.

Note:

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"

In absolute mode:

ABS

-Press this key until the ABS LED is turned 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.

V0612 - 20i-T / 30i-T - Installation/Operation - DRO operation - (9/32)

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

- 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.

Notes:

The presets done with any tool in incremental mode change the part zero for all the tools.

If a tool offset has been preset in Z

1

, Z

2

or Zs mode, that tool must be used in the same mode (Z

1

, Z

2

or Zs) when using it to machine the part.

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.

2.4.2 Deleting all tool offsets

To delete the offsets of ALL the tools. Press this keystroke sequence: It will show the text: " Delete?

",

Press [ENTER] to validate the operation or [C] to cancel it.

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.

Value

• Without removing the tool, set the X axis in HOLD mode.

• Remove the tool and measure the resulting diameter.

• Preset the part diameter. That value will be preset as the offset of the selected tool.

• Exit the HOLD mode.

V0612 - 20i-T / 30i-T - Installation/Operation - DRO operation - (11/32)

Tool change 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.

- 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.

Note:

If the feedback device is a steel tape type 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 installation parameters to configure it for a particular application.

The way these 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.

to

• If it is a general parameter, the X display will show the parameter number and the Z its current value; if there is only one axis, its number will appear on the X display and, after pressing , 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 of the display and [8] to the leftmost digit.

• Numeric values, usually with the corresponding axis resolution, they are entered as regular coordinate preset.

• Options; the value is changed by pressing this key which will make the various options appear in a cyclic way.

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.

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.

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.
