1. UNITDESCRIPTION
This NV-300T / NV-301T DRO is designed for industrial environments,
especially on lathes
It can display the position of two axes or one axis and the combination of the
second axis with a third one.
1.1 FRONTPANEL
3rd display
Each axis display has eight 14.1mm high LEDs and another one for the minus
sign (-).
ABS-This lamp stays on when operating in absolute mode and off when in
incremental mode. To access or quit this mode, use the key.
ΦΦ
ΦΦ
Φ- This lamp 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
the key.
HOLD- This lamp comes on when "freezing" the axis position by
pressing and the axis key.

it or quit it, press key.
TOOL- This lamp stays on when setting the tool.
"PROBE" This lamp is not used on this model.
3er display The rightmost digit shows a "1", a "2" or is off to indicate that
the Z axis display (2nd one) corresponds to "Z1", "Z2" or to the
combination of "Z1+Z2" respectively.
This selection rotates by pressing . It also shows the text
"tool" followed by the number of the active tool corresponding
to the XZ coordinates shown on the other displays.
Keys to select the first or second axis respectively.
Key to select whether the 2nd display corresponds to "Z1", "Z2" or to
the combination of "Z1+Z2" respectively. Every time this key is pressed,
the rightmost digit of the 3rd display rotates from "1" to "2" and off
respectively.

2.2 POWERANDMACHINECONNECTION
This DRO can be connected to an AC voltage anywhere between 100V AC
and 264 V AC +10% -15% with a frequency between 45 Hz and 400 Hz
without having to select it depending on the country where they are installed
thanks to their universal power supply.
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 mm2).
2.3 TURNING THEUNITONAND OFF
Turning the unit ON
The unit is turned on by actuating on the power switch of the rear panel
The DRO runs a self-test and shows on the X axis display the text: "FAGORdro"
if everything is OK and the error number if otherwise. See the appendix at the
end of this manual.
Turning the unit OFF
If you press the DRO turns off the displays while maintaining the power
supply to the feedback systems and goes on reading the position of the axes
at all times. This is not the case when the equipment is switched off by means
of the switch on its rear panel.
To reset the displays, just press this key again, on condition that the DRO is
getting voltage (plugged in and with the switch on the rear panel on).
Notes:
- Before powering the DRO down with the switch on the rear panel or disconnecting
it from mains, it is a good idea to press the key in order to store the current
position of the axes permanently.
- If the unit is powered down with its rear panel switch or there is a power outage
without previously having pressed , the DRO will keep the last position of the
axes for at least 30 minutes.
- The unit will display ERROR 2 when powered back up if the position reading was
lost when turned off while the axes were moving or after the accidental backup
period has expired without having saved the current position by previously press-
ing .

3. PARAMETERSETTING
This DRO has a number of installation parameters to configure it for a
particular application.
The format for these parameters depends on whether they are general or
particular for each axis.
. If it affects the axes, the parameter number (PAR??) appears at each axis
and the corresponding axis key must be pressed to modify it.
. If it is a general parameter and there are more than one axis, the Xdisplay
will show the parameter number and the Zits current value; if there is only
one axis, its number will appear on the Xdisplay and, after pressing ,
its value.
There are several kinds of parameters depending on how to set them:
· With binary values. The value of each digit toggles between "0" and "1"
whenpressingitscorrespondingkeyfrom to where corresponds
to the rightmost digit and to the leftmost one.
· Numeric values, usually with the corresponding axis resolution, they are
entered as regular preset.
· Options, the value is changed by pressing +-which will make the various
options appear in a cyclic way.
To edit a parameter, the DRO displays must be on. Then press CON
OFF .
The X axis display shows the word "COdE". Then key in: 060496
Then, select the axis affected by this parameter.
Once in regular display mode, parameter PAR05 (scaling factor) may also
be recalled by pressing C, so the work mode may be changed
without having to go through all the parameters previous to the desired
one.
To go directly to a particular parameter without going through the
previous ones, (once in parameter editing mode) press:
[parameter Nr.] ENTER .

Installation Manual - Page: 15
NV-300T/301T Man: 9910 Soft: 2.xx
To end editing a parameter, follow one of these steps:
. Press ENTER , to save the displayed value.
. Press Cto cancel the change and recover the previous value or---
. Press the other axis key (if it is an axis parameter) to save the display
value and go on to the editing it for the other axis selected.
To modify a parameter, press ENTER to go on to the next one or 12to return
to the previous one. Then, select the axis affecting this parameter.
To quit the parameter editing mode:
Press C
To recover the factory set for the installation parameters:
While displaying parameter PAR00, press:

PAR01 Feedback resolution. Independent for each axis.
Possible values: from 0.1µm up to 1 mm (0.000005" to 0.03937").

The selection of these values rotates by pressing
The factory setting is: x4 and it is the one used for FAGOR scales.
When using encoders, it should be calculating according to the
number of pulses of the encoder, leadscrew pitch and the desired
resolution as per the formula:
Encoder (lines/turn)= Leadscrew pitch (mm/turn)
Resolution (mm/pulse) xF
Where "xF" would be the multiplying factor to be applied.
