I
Operating Modes
The VUE has two operating modes: Distance-To-Go (incremental), and Actual Value (absolute). The Distance-To-Go feature enables an approach to nominal positions by traversing to display value zero.
When working within the incremental mode, enter nominal coordinates as either incremental, or absolute dimensions. The Actual
Value feature always displays the current actual position of the tool, relative to the active datum. In this mode, all moves are made by traveling until the display matches the nominal position that is required.
While in the absolute (Actual Value) mode, if the VUE is configured for
Milling applications, only the tool length offsets are active. Both the diameter, and length offsets are used in the incremental (Distance-To-
Go) mode to calculate the amount of “distance-to-go” required to get to the desired nominal position relative to the edge of the tool that will be doing the cutting.
If the VUE is configured for turning, all tool offsets are used in both the absolute, and incremental modes.
U
Press the ABS/INC hard key to toggle between these two modes.
To view other soft key functions in either absolute, or incremental mode, use the LEFT/RIGHT arrow keys.
The turning application provides a quick method for coupling the Z
axes position on a 3 axis system. For more information, see "Coupling" on page 30.
Reference Mark Evaluation
The VUE reference mark evaluation feature automatically reestablishes the relationship between axis slide positions, and display values that were last defined by setting the datum.
For each axis with an encoder that has reference marks, the REF indicator will flash for that axis. After crossing over the reference marks, the indicator will stop flashing, and change to a non-flashing
“REF”.
VUE 3
4
Working without reference mark evaluation
The VUE can also be used without crossing over the reference marks.
U Press the NO REF soft key to exit the reference mark evaluation routine, and continue.
The reference marks can still be crossed over at a later time if it becomes necessary to define a datum that can be re-established after a power interruption.
U Press the ENABLE REF soft key to activate the position recovery routine.
If an encoder is setup without reference marks, then the
REF indicator will not be displayed, and a datum set from any axis will be lost once power is turned off.
ENABLE/DISABLE REF function
The ENABLE/DISABLE soft key, that is present during the position recovery routine, allows the operator to select a specific reference mark on an encoder. This is important when using encoders with Fixed
Reference Marks (instead of ones with Position-Trac™ feature). When the DISABLE REF soft key is pressed, the recovery routine is paused, and any reference marks that are crossed during encoder movement are ignored. When the ENABLE REF soft key is then pressed, the recovery routine once again becomes active, and the next crossed reference mark will be selected.
Only cross over the reference marks of all the encoders that are needed.
U Once reference marks for all desired axes are established, press NO
REF soft key to cancel out of routine. If all reference marks have been found, the VUE will return to the DRO display screen automatically.

Units
The Units form is used to specify the preferred display units, and format. The unit of measure can also be selected by pressing the
INCH/MM soft key in either Actual Value, or Distance-To-Go mode.
Scale Factor
The scale factor may be used to scale the part up, or down. A scale factor of 1.0 creates a part with the exact size as dimensioned on the print. A scale factor >1 “grows” the part, and <1 “shrinks” the part.
U
The numeric keys are used to enter a number greater than zero. The number range is 0.1000 to 10.000. A negative value may also be entered.
U The scale factor settings will be retained on a power cycle.
U
When the scale factor is a value other than 1, the scaling symbol is shown on the axis display.
U The ON/OFF soft key is used to disable the current scale factors.
Mirror
A scale factor of -1.00 will produce a mirror image of the part. A part can be both mirror, and scaled at the same time.

Console Adjustment
The LCD’s contrast can be adjusted either by using the soft keys in this form, or by using the UP/DOWN arrow keys on the keypad in either operating mode. The contrast may need to be adjusted due to variations in ambient lighting, and operator preference. This form is also used to set the display saver’s idle time-out. The display saver setting is the amount of time the system is idle before the LCD switches to screen saver mode. The idle time may be set from 30 to
120 minutes. The display saver can be disabled during the current power cycle.
Language
The VUE supports multiple languages. To change the language selection:
U Press the LANGUAGE soft key until the desired language selection appears on the soft key, and the form.
U Press ENTER to confirm the selection.

Job, and Installation Setup parameters can be imported, or exported over the “Regular Type B” USB port.
U Press the IMPORT/EXPORT soft key in the Setup screen.
U Press IMPORT to download operating parameters from a PC.
U Press EXPORT to upload the current operating parameters to a PC.
U To exit, press the C key.
Set/Zero Soft Key
The SET/ZERO soft key is a key that determines the effect of pressing an Axis key. This key is a toggle key, switching the functionality between Set, and Zero. The current state is indicated in the Status Bar.
When the state is Set, and the VUE is in Actual Value mode, selecting an Axis key opens the Datum form for the selected axis. If the VUE is in Distance-To-Go mode, a Preset form opens.
When the state is Zero, and the VUE is in Actual Value mode, selecting an Axis key sets the current datum for that axis to zero at the current position. If it is in Distance-To-Go mode, the current Distance-To-Go value is set to zero.
If the VUE is in Actual Value mode, and the state of Set/
Zero is zero, pressing any Axis key resets the current datum to zero at the current location for that axis.

I – 2 Milling Specific Operations
This section discusses operations, and soft key functions specific to milling applications only.
Key Functions Detailed
Tool Hard Key
This hard key opens the tool table, and provides access to the Tool form for entering a tool’s parameters (a soft key is used on a one axis readout). The VUE can store up to 16 tools within the tool table.
Tool Table
The VUE tool table provides a convenient way to store diameter, and length offset information for each of the tools commonly use. Up to
16 tools can be entered.
The following soft keys are also available while in the Tool Table form, or in the individual tool data form:
Function
This key allows the operator to select which axis all the tool length offsets will affect. The tool’s diameter values will subsequently be used to offset the remaining two axes.
Soft key
Press to automatically enter the tool offset length. Only available in Tool Length field.
This will open the Tool Types form for selection. Only available in TYPE field.
Tool Compensation
VUE has tool compensation. This allows workpiece dimensions to be entered directly from the drawing. The displayed distance to go is then automatically lengthened (R+), or shortened (R–) by the value of the
tool radius. for more information see "Presets" on page 12.
The length offset may be entered as a known value, or the VUE may determine the offset automatically. The tool length is the difference in length
Δ
L between the tool, and the reference tool. The length difference is indicated with the “
Δ
“ symbol. The reference tool is indicated by T1.
I
Sign for the length difference
Δ
L
If the tool is longer than the reference tool:
Δ
L > 0 (+).
If the tool is shorter than the reference tool:
Δ
L < 0 (–).
As indicated above it is also possible to have the VUE determine a tool’s length offset. This method involves touching the tip of each tool to a common reference surface. This allows the VUE to determine the difference between the length of each tool.
Move the tool until its tip is touching the reference surface. Press the
TEACH LENGTH soft key. The VUE will calculate an offset relative to this surface. Repeat the procedure for each additional tool using the same reference surface.
Only the tools set using the same reference surface may be changed without having to reset the datum.
Calling the Tool from the Tool Table
U To call a tool, press the TOOL hard key.
U Use the UP/DOWN arrow keys to Cursor through the selection of tools (1-16). Highlight the tool wanted.
U Verify the proper tool has been called, and press the tool, or C key to exit.
VUE 9
Datum Setting
Datum settings define the relationships between the axis positions, and the display values.
Setting datum points can be done by using the VUE probing functions with a tool.
Datum points are set by touching the edges of the workpiece, one after the other with a tool, and manually entering the tool positions as datum points.
10 I
Datum Setting with a Tool
Using a tool to set datum points can still use the VUE probing functions.
The following probing soft key functions are available:
Workpiece edge as datum: EDGE soft key
Centerline between two workpiece edges: CENTER LINE soft key.
Center of a hole, or cylinder: CIRCLE CENTER soft key.
In all probing functions, VUE takes into account the current tool’s entered tip diameter.
To abort the probing function while it is active, press the C key.
Example: Probe workpiece edge, and set edge as datum
U Preparation: Set the active tool to the tool that will be used to set the datum.
Datum axis: X =0
Tool diameter D = 0.25”
U Press DATUM hard key.
U Press the DOWN arrow key until the X axis field is highlighted.
U Press PROBE soft key.
U Press EDGE soft key.
U Touch workpiece edge.
U Press the TEACH soft key to store the current absolute value while the tool is in contact with the workpiece edge. The location for the touched edge will take into account the diameter of the tool in use
(T:1, 2...), and the last direction the tool was moved prior to pressing the TEACH soft key.
U Retract the tool from the workpiece, enter 0”, and then press
ENTER.
VUE 11
Presets
The Preset function allows the operator to indicate the nominal (target) position for the next move. Once the new nominal position information is entered the display will switch to Distance-To-Go mode, and show the distance between the current position, and the nominal position. The operator now only needs to move the table until the display is zero, and he will be at the required nominal position. The information for the location of the nominal position can be entered as an absolute move from the current datum zero, or as an incremental move from the current nominal position.
Presetting also allows the operator to indicate which side of the tool will be doing the machining at the nominal position. The R+/- soft key in the Preset form defines the offset that will be in effect during the move. R+ indicates that the center line of the current tool is in a more positive direction than the edge of the tool. R- indicates that the center line is in a more negative direction than the edge of the current tool.
Using R+/- offsets automatically adjusts the distance-to-go value to account for the diameter of the tool.
Absolute Distance Preset
Example: Milling a shoulder by traversing to display value zero using absolute position
The coordinates are entered as absolute dimensions; the datum is the workpiece zero.
Corner 1: X = 0 / Y = 1
Corner 2: X = 1.50 / Y = 1
Corner 3: X = 1.50 / Y = 2.50
Corner 4: X = 3.00 / Y = 2.50
Pressing an axis key recalls the last entered preset value for that axis.
12 I
Preparation:
U Select the tool with the appropriate tool data.
U Pre-position the tool to an appropriate location (such as X = Y = -1”).
U Move the tool to milling depth.
U Press the SET/ZERO soft key so that the DRO is still in Set mode.
U Press the Y axis key.
U Enter nominal position value for corner point 1: Y = 1”, and select tool radius compensation R + with R+/- soft key. Press until R+ is shown next to axis form.
U Press ENTER.
U Traverse the Y axis until the display value is zero. The square in the near zero warning is now centered between the two triangular marks.
U Press the SET/ZERO soft key so that the DRO is still in Set mode.
U Press the X axis key.
U Enter nominal position value for corner point 2: X = +1.5”, select tool radius compensation R – with R+/- soft key. Press twice until R- is shown next to axis form.
U Press ENTER.
U Traverse the X axis until the display value is zero. The square in the near zero warning is now centered between the two triangular marks.
U Presets can be entered in the same manner for corners 3, and 4.
VUE 13
Incremental Distance Preset
Example: Drilling by traversing to display value zero with incremental positioning.
Enter the coordinates in incremental dimensions. These are indicated in the following (and, on the screen) with a preceding I (Incremental). The datum is the workpiece zero.

I – 3 Turning Specific Operations
This section discusses operations specific to turning applications only.
Tool Table
The VUE can store the dimensional offsets for up to 16 tools. When changing a workpiece, and establish a new datum, all tools are automatically referenced from the new datum.
Before a tool can be used, enter its offset (the cutting edge position).
Tool offsets can be set using the Tool/Set, or Lock Axis features. See the following examples for instructions on Tool Offsetting.
Tool Display Icon
The
∅ icon is used to indicate that the displayed value is a diameter value. No icon visible indicates that the display is a radius value.
Setting Tool Offsets with Tool/Set
Example 1: Using Tool/Set
The Tool/Set operation can be used to set a tool’s offset using a tool when the diameter of the workpiece is known.
U
Touch the known diameter in the X axis (1).
U Press the TOOL hard key.
U
Scroll to the desired tool.
U Press the ENTER key.
U
Select the X axis key.
U Enter the position of the tool tip, for example, X= .100. Remember to ensure the VUE is in diameter display mode (Ø) if a diameter value is used.
U
Touch the workpiece face with the tool.
U Cursor to the Z axis (2), then set the position display for the tool tip to zero, Z=0.
U
Press ENTER.
22 I
Setting Tool Offsets with Lock Axis Function
Example 2: LOCK AXIS
The LOCK AXIS function can be used to set a tool’s offset when a tool is under load, and the diameter of the workpiece is not known.
The LOCK AXIS function is useful when determining tool data by touching the workpiece. To avoid losing the position value when the tool is retracted to measure the workpiece, this value can be stored by pressing LOCK AXIS.
To use the LOCK AXIS function:
U Press the TOOL hard key.
U Select tool, and press ENTER.
U Press the X axis key.
U Turn a diameter in the X axis.
U Press the LOCK AXIS soft key while the tool is still cutting.
U Retract from the current position.
U Turn the spindle off, and measure the workpiece diameter.
U Enter the measured diameter, or radius, and press ENTER.
Remember to ensure the VUE is in diameter display mode (Ø).
Calling a Tool from the Tool Table
U To call a tool, press the TOOL hard key.
U Use the UP/DOWN arrow keys to Cursor through the selection of tools (1-16). Highlight the tool wanted.
U Verify the proper tool has been called, and press either the use the
TOOL soft key, or the C key to exit.
VUE 23
Datum Setting
See "Datum Setting" on page 10 for basic information. Datum settings
define the relationships between the axis positions, and the display values. for most lathe operations there is only one X-axis datum, the center of the chuck, but it may be helpful to define additional datums for the Z-axis. The table can hold up to 10 datum points. The easiest way to set datum points is to touch a workpiece at a known diameter, or location, then enter that dimension as the value that the display should be showing
Example: Setting a workpiece datum
U Call the tool data by selecting the tool which being used to touch the workpiece.
U Press the DATUM hard key. The Cursor will be in the Datum
Number field.
U Enter the datum number, and press the DOWN ARROW key to go to the X-axis field.
U Touch the workpiece at point 1.
U Enter the radius, or diameter of the workpiece at that point.
Remember to ensure the VUE is in diameter display mode (Ø) if a diameter value is used.
U Press the DOWN ARROW key to advance to the Z axis.
U Touch the workpiece surface at point 2.
U Enter the position of the tool tip (Z= 0) for the Z coordinate of the datum.
U Press ENTER.
24 I
Setting Datums using LOCK AXIS Function
The Lock Axis function is useful for setting a datum when a tool is under load, and the diameter of the workpiece is not known.
To use the Lock Axis function:
U Press the DATUM hard key. The Cursor will be in the Datum
Number field.
U Enter the datum number, and press the DOWN ARROW key to go to the X axis field.
U Turn a diameter in the X axis.
U Press the LOCK AXIS soft key while the tool is still cutting.
U Retract from the current position.
U Turn the spindle off, and measure the workpiece diameter.
U Enter the measured diameter, for example, 1.5”, and press ENTER.
VUE 25
Taper Calculator Hard Key
Use the taper calculator to caculate taper angle.
Calculate tapers either by entering dimensions from a print, or by touching a tapered workpiece with a tool, or indicator.
Entry values:
For the taper ratio, calculation requires:
Length of the taper
Change in the radius of the taper.
For taper calculation using both diameters (D1, D2), and length requires:
Starting diameter
End diameter
Length of the taper
Using Taper Calculator
U Press the CALC hard key: The soft key selection now changes to include the taper calculator funtions.
U To calculate the taper angle using two diameters, and length between, press the taper: di/D2/l soft keys.
U First taper point, diameter 1, either enter a point using the numeic keys, and press enter, or touch the tool to one point, and press note.
U Repeat this for the diameter 2 field. When using the NOTE key, the taper angle is automatically calculated. When entering data numerically, enter data into the length field, and press ENTER: The taper angle will appear in the angle field.
U To calculate angles using the ratio of the diameter, change to length, and press the taper: RATIO soft key.
U Using the numeric keys, enter data into the ENTRY 1, and ENTRY 2 fields.
U Press ENTER after each selection: The calculated ratio, and the angle will appear in their respective fields.
26 I
Presets
The functionality has been explained previously in this manual (See
"Presets" on page 12). The explanation, and examples on those pages
are based on a mill application. The basics of those explanations are the same for turning applications with two exceptions; Tool Diameter
Offsets (R+/-), and Radius vs. Diameter inputs.
Tool diameter offsets have no applications with turning tools, so this functionality is not available while doing turning presets.
Input values can be either radius, or diameter values. It is important to be sure the units being entered for the preset agree with the state that the display is currently using. A diameter value is shown with a (Ø) symbol. The state of the display can be changed using the RAD/DIA soft key (available in both operating modes).
RADIUS/DIAMETER Soft Key
Drawings for lathe parts usually give diameter values. VUE can display either the radius, or the diameter. When the diameter is being displayed, the diameter symbol (Ø) is shown next to the position value.
Example:
Radius display, position 1, X = .50
Diameter display, position 1, X = Ø 1.0
U Press the RAD/DIA soft key to switch between radius display, and diameter display.
VUE 27
Vectoring
Vectoring breaks down the movement of the compound axis into the crossfeed, or longitudinal axes. When turning threads for example, vectoring provides the diameter of the thread in the X-axis display, even though the cutting tool is moving with the compound axis handwheel. With vectoring enabled, the desired radius, or diameter in the X-axis can be preset, allowing “machine to zero”.
When vectoring is used, the top slide (compound) axis encoder must be assigned to the bottom display axis. The crossfeed component of movement of the axis will then be shown in the top display axis. The longitudinal component of movement of the axis will be shown in the middle display axis.
U Press the VECTORING hard key.
U Press the ON soft key to enable the vectoring feature.
U Arrow down to the Angle field to enter the angle between the longitudinal slide, and top slide with 0° indicating the top slide is moving parallel to the longitudinal slide.
U Press ENTER.

II – 1 Installation Setup
Installation Setup Parameters
Installation Setup is accessed by pressing the SETUP soft key, which brings up INSTALL. SETUP soft key.
Installation Setup parameters are established during the initial installation, and most likely, will not often change. For this reason, the installation setup parameters are protected by the passcode.
See "Readout Parameter Access Code" on page v.
After entering the Access Code, the cursor will default to the Encoder
Setup field upon opening Installation Setup.
Encoder Setup
The Encoder Setup form is used to set the encoder resolution, and type (linear, rotary), count direction, reference mark type.
U Press ENTER. This opens a list of possible encoder inputs.
U Scroll to the encoder to be changed, and press ENTER.
U Cursor will be in the Encoder Type field. Select the encoder type by pressing the LINEAR/ROTARY soft key.
U For linear encoders, cursor to the Resolution field and use the
COARSER, or FINER soft keys to select the encoder’s resolution (in
µm 10, 5, 2, 1, 0.5). The exact resolution can also be entered using the numeric key pad. For rotary encoders, enter the number of counts per revolution.
U In the Reference Mark field, toggling the REF MARK soft key selects whether the encoder has no reference signal with NONE, single reference mark with the SINGLE or with the P-TRAC soft key for encoders with the Position-Trac™ feature.
U In the Count Direction field, select the count direction by pressing the POSITIVE, or NEGATIVE soft key. If the encoder’s count direction matches the user’s count direction, select positive. If the directions do not match, select negative.
VUE 29

180°, ± infinity, or RPM.
Coupling
U Press the numeric keys associated with the encoder input on the back of the unit. Press the + or - soft keys to couple a second input with the first. The input numbers are displayed next to the axis label indicating that the position is a coupled position (i.e. “2 + 3”).
30
Z Coupling (turning applications only)
The VUE Turning application provides a quick method for coupling the
Z0, and Z axis position on a 3 axis system. The display can be coupled in either the Z, or Z0 displays.
Enabling Z Coupling
U To couple the Z0, and Z axis, and have the result displayed on the Z0 display, press and hold the Z0 key approximately 2 seconds. The sum of the Z positions will be displayed on the Z0 display, and the Z display will be blanked.
U To couple the Z0, and Z axis, and have the result displayed on the Z display, press and hold the Z key for approximately 2 seconds. The sum of the Z positions will be displayed on the Z display, and the Z0 display will be blanked. The coupling is preserved in between power cycles.
Moving either Z0, or Z inputs will update the coupled Z position.
When a position is coupled, the reference mark for both encoders must be found in order to recall the previous datum.
Disabling Z Coupling
U To disable Z Coupling, press the axis key of the display that is blank.
The individual Z0, and Z display positions will be restored.
VUE 31
Error Compensation
The distance a cutting tool travels, measured by an encoder, can in certain cases, differ from the actual tool travel. This error can occur due to ball screw pitch error or deflection and tilting of axes. This error can either be linear, or non-linear. These errors can be determined with a reference measurement system, ex. gauge blocks, laser, etc. From an analysis of the error, it can be determined which form of compensation is required, linear, or non-linear error.
The VUE provides the opportunity to compensate for these errors, and each axis can be programmed separately with the appropriate compensation.
Error compensation is only available when using linear encoders.
Linear Error Compensation
Linear error compensation can be applied, if the results of the comparison with a reference standard show a linear deviation over the whole measuring length. In this case the error can be compensated by the calculation of a single correction factor.
To calculate the linear error compensation use this formula:
Correction factor LEC = (S – M) x 10
6
ppm with
S
M
measured length with reference standard measured length with device at axis
Example:
If the length of the standard used is 500 mm, and the measured length along the X-axis is 499.95, then the LEC for the X-axis is 100 parts per million (ppm).
LEC = (500 – 499.95) x 10
6
ppm = 100 ppm (rounded to the nearest
whole number).
U
Once determined, the encoder’s error information is entered directly. Press the TYPE soft key to select LINEAR compensation.
U Enter the compensation factor in parts per million (ppm) and press the ENTER key.
32
Non-Linear Error Compensation
Non-linear error compensation should be applied, if the results of the comparison with a reference standard show an alternating or oscillating deviation. The required correction values are calculated and entered in a table. VUE supports up to 200 points per axis. The error value between two entered adjacent correction points is calculated with linear interpolation.
Non-linear error compensation is only available on scales with reference marks. If non-linear error compensation has been defined, no error compensation will be applied until the reference marks have been crossed.
Starting a Non-linear Error Compensation Table
U Select Non-linear by pressing the TYPE soft key.
U To start a new error compensation table, first press the EDIT TABLE soft key.
U All correction points (up to 200) are equally spaced from the start point. Enter the distance between each of the correction points.
Press the DOWN arrow key.
U Enter the table’s start point. The start point is measured from the scale’s reference point. If this distance is not known, move to the location of the start point, and press TEACH POSITION. Press
ENTER.
Configuring the Compensation Table
U Press the EDIT TABLE soft key to view the table entries.
U Use the Up or Down arrow keys or the numeric keys to move the cursor to the correction point to be added or changed. Press ENTER.
U Enter the known error which exists at this point. Press ENTER.
U When completed, press C key to exit the table and return to the
Error Compensation form.
Reading the Graph
The error compensation table may be viewed in table or graphical formats. The graph shows a plot of a translation error vs. measured value. The graph has a fixed scale. As the cursor is moved through the form, the location of the point on the graph is indicated with a vertical line.
VUE 33
Viewing the Compensation Table
U Press the EDIT TABLE soft key.
U To switch between the table and graph views, press the VIEW soft key.
U Press the Up or Down arrow keys or the numeric keys to move the cursor within the table.
The error compensation table data may be saved to or loaded from a
PC via the USB port.
Exporting the Current Compensation Table
U Press the EDIT TABLE soft key
U Press the IMPORT/EXPORT soft key.
U Press the EXPORT TABLE soft key.
Importing a New Compensation Table
U Press the EDIT TABLE soft key.
U Press the IMPORT/EXPORT soft key.
U Press the IMPORT TABLE soft key.
Backlash Compensation
When using a rotary encoder with a lead screw, a change in direction of the table might cause an error in the displayed position due to clearances within the lead screw assembly. This clearance is referred to as backlash. This error can be compensated for by inputting the amount of backlash within the lead screw into the Backlash
Compensation feature.
If the rotary encoder is ahead of the table (displayed value is greater than the table’s true position), this is called positive backlash and the value entered should be the positive value of the amount of error.
No Backlash Compensation is 0.000.
34
Counter Settings
The Counter Settings feature is the parameter where the operator defines the user application for the readout. The choices are for milling or turning applications.
A FACTORY DEFAULT soft key appears in the Counter Settings choice of options. When pressed, the configuration parameters (based on either mill or turn) will be reset to factory defaults. The operator will be prompted to press YES to set parameters to factory default settings or NO to cancel and return to previous menu screen.
The Number of Axes field sets the number of axes needed. A 1, 2, or
3 soft key will appear to choose between either 1, 2 or 3 axes.
The Position Recall feature, when it is “ON”, will store the last position of each axis when power was turned off and then redisplay that position once power is turned back on.
Note that any movement that occurs while power is off will be lost. Whenever power has been off it is recommended to re-establish workpiece datums using the
Reference Mark Evaluation procedure. See "Reference
