Page 8: Unit Description
UNIT DESCRIPTION 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. FRONT PANEL display Each axis display has eight 14.1mm high LEDs and another one for the minus sign (-). - Page 9 INCH- This lamp stays on when working in inches and off when doing it in millimeters. To access it or quit it, press This lamp stays on during machine reference search . To access it or quit it, press key. TOOL- This lamp stays on when setting the tool.

REAR PANEL Dimensions of the Built-in model: On the back of the unit the following items may be found: 1.- Power switch. When the unit is turned off by this switch, the DRO no longer reads axis position. Therefore, it is recommended to use the at the front panel to turn the display off so the DRO continues keeping track of the axes position when they are moved. -

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: "FAGOR dro" if everything is OK and the error number if otherwise. See the appendix at the end of this manual. -
Page 15: Parameter Setting
PARAMETER SETTING 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. - Page 16 To end editing a parameter, follow one of these steps: . Press , to save the displayed value. ENTER . Press to 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.

Page 17: Parameters To Configure Axis Count And Display
PARAMETERS TO CONFIGURE AXIS COUNT AND DISPLAY The digits of digital parameters refer to the digits on the axis displays so digit "1" corresponds to the rightmost digit and "8" to the leftmost digit. PARA- METER FUNCTION PAR00 Feedback configuration, different for each axis. Binary type. Digit Direction of the coded Io (0 = Increasing, 1 = Decreasing) Pitch of the coded Io (0 = 20 mm, 1 = 100mm) - Page 18 Options: x4, x2, x1 and x0.5. 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...
- Page 19 PAR08 Indicates whether the alarms for feedrate, travel limits and feedback will be activated or not. Digit 8, 7, 6 Not being used at this time. Must be set to "0". Detect feedback signal weakness on NVxx1 models. Value for the feedback alarm contact (0=low, 1=high) Detect feedback alarm provided by the scale.
- Page 20 LED is off or on. PAR 14 To carry out the home search when the feedback device does NOT have reference marks "Io" (for example, FAGOR MKT scales), this parameter must be set to "1". This way it is possible to preset a home value in Machine Reference mode.

If an axis does not count, disconnect the feedback connectors one by one. If the DRO comes on, it indicates a fault in the feedback device. If the fault persists get in touch with Fagor Automation’s Customer Services Department about it. -
Page 22: Maintenance
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. - Page 23 FAGOR DRO NV-300T NV-301T OPERATION MANUAL Man: 9910 Soft: 2.xx...

Therefore, it is recommended to use the at the front panel to turn the display off so the DRO continues keeping track of the axes position when they are moved. - Page 29 WARNING Do not handle the connectors while the unit is under power. Before handling the connectors (mains, feedback, etc.) make sure that the unit is not under power. It is NOT enough to turn the display off by using the key at the keyboard.

Page 31: Incremental, Absolute And With Respect To Machine Reference Zero
For example: If a counting resolution of 0.005 mm was selected (taking into account the type of scale etc.) by the installation parameter PAR01, it could occur that it is enough for the operator to display every 0.010 mm (0.020, 0.030, etc.) so that the right- hand digit is not required (0.01, 0.02, 0.03, etc.). - Page 32 In Incremental (I), when the ABS and leds are off the distance from the present position of the axis to the previous position is displayed. Note: On this model, the incremental reading is linked to the absolute so when presetting a new part zero, the incremental zero will also change maintaining the previous distance relative to the part zero.
-
Page 33: Machine Reference Selection And Search
Standard FAGOR scales have a fixed reference mark (Io) every 50 mm along their travel. FAGOR also offers scales with a coded Io every 20 mm or every 100 mm (depending on the model) with which all you have to do is move the axis at most 20 mm or 100 mm from the present position in order to “find”... - Page 34 MACHINE REFERENCE (HOME) SEARCH FOR FEEDBACK WITHOUT REFERENCE MARKS When using feedback devices without reference marks (FAGOR MKT scales, for instance) a Home value may be preset or zeroed by pressing in that mode (led ON).

Page 35: Axis Coordinate Preset
AXIS COORDINATE PRESET To reset the axis display, just press: sequence: for "X", and for "Z". 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"... - Page 36 or... - Preset the axis with value 22.601 by pressing: 22.601 ENTER validate it. In case of a mistake, press to cancel it and leave it as it was. When pressing , the previously preset value is displayed. - 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.
-
Page 37: Special Operations
In absolute mode: Press until the ABS led comes on. To preset part zero: - Place the axis exactly over “0” and press: At any time, by pressing key , the DRO will display the present position with respect to the previous zero (ABS and leds off), to part zero (ABS led on) or with respect to home ( led on). -
Page 38: 3.2 Tool Preset
3.2 TOOL PRESET Up to ten tools may be preset on this DRO model (from "tool 0" to "tool 9"). The unit stores in its internal memory the relative offsets of all the tools with respect to that of "T0". Therefore, if "T0"... -
Page 39: Coordinate Freeze (Hold)
COORDINATE FREEZE (HOLD) It enables “freezing” the display of the counter while 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. For example, to change a tool at any known point of the part: - Press key and the display counting said axis “freezes”... -

Power outage or turned off by main switch without having saved the data. Error 02 The unit has been turned off without previously pushing the [ON/OFF] key. It will only lose the position count (will be reset to zero) and the status of the operating modes (inch, abs, etc.).
