MILLVISION was designed and built with à modular concept. The
chassis assembly, the video unit, the axis modules and the central The modular
processing unit (CPU) are modular units. The axis modules and ihe CONCEept
CPU module are slide-in boards. The module slots are designed so
that onty the corresponding module can go into each sio.
The viewing screen (CAT) and chassis assembly are not intended
to be maintained in the field. The unit should be retumed to me
distributor if there are problems wilh the screen, on/off switch, con-
trast, or keypad.
MILLVISION was designed to make board replacement and in-
stallation of additional options (boards) possible on the Job site.
It should be noted, however, that changing modular boards is
the only level of maintenance authorized by ACU-RITE. If the pro-
blem is not a board-related malfunction, the entire unit must be
returned for service.
The standard 2-axis MILLVISION can be upgraded 10 4-axis by Ihe
addition of an axis module (PN 387802-6000) 10 one of tha ap- Additional axes
propriate expansion siots (Figure 2).

The standard MILLVISION can be expanded to a "fulloption”' VRO ñ
by adding the option module (Part Number 3878004060) into an ex- Option module
pansion slot. A full-option MILLVISION has the following capabilities:
* RS-232C Serial Communications
* Electronic Edge Finder Input
* Communication For Program Storage
* Parallel Printer Communications Output
* Foot Switch Input
Insta lling/removi ng To remove an axis module or a CPU module, proceed as follows:

N any of the above steps cannot be completed or if any of the screens
differ trom the above descriptions, contact your ACU-RITE distributor
or OEM,
Location is an important consideration for prôper installation. The
following points should be kept In mind when selecting a safe and
convenient location:
1) Ease of operator reach,
2) Approximate aye level to the operator.
3) Avoid moving components or tools, and coolant splash.
4) Operating environment must be 05 10 40° C. with à non-
condensing relative humidity of 25-85%.
5) MILLVISION's CAT, like all CRTs, can be adversely af-
fected by a strong magnetic field. Therefore, it should be
mounted away from any source of magnetism and magnetic
base holders should never be set on top of MILLVISION
6) To avoid overheating, MILLVISION should have adequate
airflow around and under the unit. Access to the filter
assembly 15 also needed for periodic maintenance,
For further information refer to the Troubleshooting ‘“Ven-
tilation system” section in the APPENDICES (page 72).
ACU-RITE has developed specific mounting kits for MILLVISION
which are applicable to masi common mounting configurations. The
kits are available from your ACU-RITE Distributor and come com-
plate with hardware and mounting Instructions.
Careful consideration should be given when fabricating a suppor
device for MILLYISION, it should be large and strong enough to ac-
commodate the readout and any other devices thal may be placed
on top (printer, etc).

MILLVISION has seven operational modes. The first mode (5 the
Power-Up mode, automatically entered when MILL VISION is turned
on or when thers has been a power interruption. The other six modes
are selected from the keyboard using the lactile mode keys along
the bottom of MILLVISION's keypad. The six user modes are as
follows:
Set System Mode - used 10 sel parameters lor the incom-
ing encoder information and to display i to the operator.
The encoder parameters should be entered into the uni
during ths installation of the system as explained on page
15.
Programming Mode - the operator can create programs
for machining repetitive parts This mode has routines 10
create, view, edit, run and learn programs (see the "PRO-
GRAM OPERATION" tab section)
Set Tool Mode - used to enter and store tool offset dimen-
sions. MILL VISION can retain information for up lo 99 tools
with offsets in three axes (see page 48).
DRO Mode - the ‘’workhorse” mode within MILLVISIÓN.
Standard machining (without a program) is done in the DRO
mode (see the “STANDARD MACHINING PRO-
CEDURES" tab section).
Calculator Mode - gives access to a four-tunction
calculator, taper calculator, and RPM calculator. The stan-
dard calculator allows the operator to do calculations us-
Ing Information directly from the preset register, and add
the calculation result! back into the preseal register (see page

To select one of these values, use the menu keys Finer” and
“Coarser until the correct value is shown for "Res (microns). To
accommodate English-uted linear encoders and linear encoders with
resolutions not listed, direct keyboard entry can be used to define
the resolution.
Clear me current resolution by using the CLEAR key and enter the
scale resolution in microns by using the numenc keys on the keypad
Note: All entries (English or Metric ruled encoders) must
be entered in microns {.001 mm). For example, to enter a
0005" resolution encoder, multiply .0005"" by 25.400
microns/inch. This translates to a metric resolution 12.7
microns which Is then keyed in as the scale resolution.
Standard resolutions for angular motion in ¿counts per revolution
(cntirev,) are as follows:
36,000.000 1,800,000 72,000 3.600
18,000.000 720,000 36,000 1,800
7.200.000 350,000 18,000 720
3,600,000 180,000 7.200 350
Note: If keyboard entry is necessary for an angular encoder,
it must be entered in counts per revolution
"FTO" refers to a signal pulse generated when a fiducial (reference)
mark on a scale is sensed by the scale reading head. This reference
mark can be used to automatically reset the readout display to zero.
Il an ACU-RITE linear encoder has FTO signals, it will be indicated
on the label as “ABSOLUTE ZERO" or "ABSOLUTE ZERO IM. The
FTO parameter isa YES or NO selection.
**Count Direction” refars 10 assigning a positive or negallve value
10 axis motion. This assignment is the preference of the end-user
or shop. Some shops feel that if the workpiece is maving 10 the left
of the tool it represents a negative movement while other shops refer
to this as a positive movement.
To sel the count direction
1) Press mode key.
2) Move the axis in question, observing Ihe motion polarity (display
becoming more negative indicates a negative count direction,
display becoming more positive indicates a positive count
direction),
I! this count direction is in agreement with shop standards, no
change for that axis Is necessary,
If the count direction is opposite from shop standards, proceed
to me following steps:
3) Press the mode key.
4) Press the "Jump to where SET SYS was left" menu key, This
should return the display to the AXIS PARAMETERS screen.

5) Make sure the axis being worked on is indicated at the top of
the screen; If not. press the correct axis key.
6) Use the "'down' arrow key to move to the "Count Direction”
parameter and then press Me opposite Status.
7} Repeal the above procedure to ensure the axis motion ls now
in agreement with shop standards.
With ACU-RITE ABSOLUTE ZERO linear encoders, FTO reterence
marks can bé used to easily locate the workpiece zero. The FTO
reference marks are ling patterns on ACU-RITE scales which are
placed at regular intervals along the scale. Every time MILLVISION
is turned off, or power is Interrupted, all axis positon information |5
lest. The readout cannot tell if the encoder has moved while the power
is off. When power is restored, MILLVISION resets all axes to 0.0
tor both the incremental and absolute displays. Therefore, the cur-
rent positions of the axes, relative lo the mounted workpiece, are
lost until the axes positions are reset. It is very important to find
the same home reference point every time MILLVISION is
powered up.
To find the home reference point proceed as follows:
1) Press the [1a] key.
2) Press the "SET REF. POINT menu key.
3) Press the corresponding axis key for the axis Ihe home reference
point (X, Y, Z. Wi.
Only axes for which parameters were set indicating they have
FTOS are now listed as available for setting home reference
points.
4) Move the axis close to an FTO mark on the scale and press the
“Ready” menu key.
5) Move slowly through the FTO mark on the scale in the positive
count direction.
The FTO mark will only be sensed if the axis is moving in a
positive count direction, Once the reading head has passed over
an FTO mark on the linear encoder, MILLVISION will indicate
the home reference point has been found.

All machine tools, new or did, contain some error in the accuracy
of indicated motion when compared 10 a standard which Is known
io be true. MILLVISION helps compensate for this form of error
To properly program for error compensation, please read this
entire section.
Machine error ls caused by al least one of the following machine
tool deficiencies:
A. The ft between mating surfaces is loose, because of either
manufacturing lolerances, subsequent wear, of impropar gib
adjustment.
B. The ways ara not scraped straight or are nol aligned perfectly
at assembly.
C. Driving and cutting forces cause deflechons {since no material
Is completely rigid).
D. Temperature gradenis can distort machine geometry.
E. Abbe’ error - daflections in he machine tool structure, caused
by gravity, particularly when a heavy workpiece is placed on a
machine with overhanging table or ways (see Figure 16).

Errors caused by C and D (above), must be compensated by using
correct machining practices and maintaming the machine in à
temperature-stable environment
Machine Inaccuracies caused by А, В and E (above), can be
significantly compensated for by programming MILLVISION's error
compensation. Since machine tool error is a constant error, It can
be measured and graphed. Error compensation values can then be
programmed into MILL VISION.

Errer Analysis (Example 1)
Error Analysis (Example 1) - Incremental moves were made along
the entire length of an axis. For each move, the readout display was
compared with the distance moved by using certified gage blocks
or by using a laser interferometer, Both the actual travel and thé travel
displayed on the readout were recorded. Tha readout measurements
were then sublracled from the actual measurements 10 represent
the error values.
The error values were plotted against Ine distance traveled. A line
was drawn representing the “best-iming” straight line among the
ploted points (Ihe lime should pass through the 0. 0 point). From the
char! and plot (Figures 17a & 17D). it can be seen that error is in-
creasing al a near constan! rate as we move along the axis. This
is an example ol single interval arror compensation.

Error Analysis (Example 2) (See next page)
The same procedure was followed for a second axis (Figures 188
& 18b). From the plot of this axis, If can be seen that the error does
not increase in the same manner as the first axis. This plot has
several different error rales as indicated by the lines with different
slopes. № Is important when “best-fitting" straight ines are developed
for these graphs, that thay are based on a number of points spread
over a significant interval, not just two or three points close together.
It this concept of the ‘’best-fitting" straight line is not used, true er-
ror slopes will not be shown.
Points close together can appear lo have a large error for he amount
of distance traveled. This is especially true for scales with relatively
course resolutions. The scale measurement! between close points
can easily be off by one resolution, This apparent error occurs
because of the digital nature of the scale, |.e. the readoul can incre-
ment two units, after moving just slightly more than one full unit
Figure 17b. Error Graph (Example 1).

Example Requirements
As shown by examples 1 4 7, error compensation can demand dit-
ferent solutions. The first axis requires a constant error correction
lactor 0f 67 counts par millon tá correct for the measurement
displayed. The second axis requires several different error correc-
tion factors in each of the different intervals 10 compensate lor the
Arrors.
MILLVISION has the capability to handie both types of emor com-
pensation. Single interval (linear) error compensation would be re-
quired to add in the constant correction factor over the entire length
of the axis for example 1. Multiple interval error compensation would
be best for example 2. With MILLVISION, eight intervals of correc-
tion factors can be used for each axis.
Methods for checking and measuring machine error

1) Set up the step gage on the table al a height and position that
coincides with that of a typical workpiece.
2) Inserta dial indicator imo the spindle and lower it until tha in-
dicator can contact the first reference surface of the gage.

If the error analysis plot has a single best-fit straight line on the graph,
single interval error compensation is the best choice for that axis
If the error analysis plol has more than one best-fit straight line, then
multiple interval error compensation is the best choice to help com-

Determining error
MILLVISION automatically calculates error correction values through
correction values MVS a ¿ais e ас
found manually, Using error plots and mathematics. While MILLVI-
SION 's automatic routines are much quicker and easier to use, in
s0me Cases, the accuracy oblained is less than what can be obtam-
ed using a manual error analysis.
The following routine is the manual method to find error values for
both single and multiple mienrval compensation, For single interval,
the mathematics are done once for each axis being compensated.
For multiple interval compensation, the same mathemalical pro-
cedure will have to be done for 2ach interval being used within an
axis. The mathematics lor both the manual and the automatic method
involves finding the slope of each compensation interval and
translating that value mio parts per millon (PPM). This value can
than be used 10 adjust the display to compensate for machine

Establishing the
home reference
point
Establishing a home reference point is the first step in implament-
wi multiple migrval error compensation. Thé home reference point
allows MILLVISION to define the same intervals for error compern-
sation every lime the uni is turned on (see below or page 17 for
establishing à home reference point).
When MILLVISION is turned off, or power is los! due lo a power
outage, all axes position information is los! and the readout cannol
tell 1 the encoder has moved, This loss ol positional memory has
a major effect on two areas within lhe unit.
The first area of impact is position information regarding the
workplece already mounted when power was interrupted. When
power is restored, MILLVISION resets all axes to 0.0 lor both the
incremental and absolute displays. Therefore, the current positions
of the axes, relative to the mounted workpiece, are lost until the axes
positions are reset. This can be done by using the SET REF. POINT
routing for each axis or by positioning Ihe axes of the machine to
known locations and manually presétting positions.
The other area that is affected by loss of posifional memary is mult
ple interval error compensation. Specific segments of the scale,
representing specific segments of travel on the machine, can each
be given arror compensation values. This specific relationship bet-
wean the scale and actual machine positions requires a home
reference point be found every time MILLVISION ts turned on. The
home reference point must be the same point which was defined
prior to establishing the intervals lor multigte interval compensation
The point must be relocated lo re-establish the correct retatiónship
between the definad intervals in MILLVISION's memory and the ac-
tual position of the machine. To find the home reference point pro-
ceed as follows:
1) Press the [3a] key
2) Press the "SET REF. POINT" menu key.
3) Press the corresponding axis key for the axis the home reference
point Is to be set
4) Move the axis close lo an FTO mark on the scale and press the
Ready" menu key.
5) Slowly move through the FTO mark on the scale in the positive
coun direccion.
The FTO mark will only be sensed if the axis is moving in a
positive count direction. Once the reading head has passed over
an FTO mark on the linear encoder, MILLVISION's screen will
indicate the nome reference point has been found.
6) Press the "Finished menu key or press the "Wrong Reference
Point” menu key to select a different point,
7) Once the reference point Is acceptable, it is extramely impor-
tant to place a mark on the scale casing al the approximate loca-
tion of the reference point (FTO), This will aid in locating the same
FTO reference point quickly each lime there 5 à need to find
Me home reference poinl
26
I IE US ES ED E SE
These FTO relerence marks and their purpose must be
understood by the machine operalor.
Repeal the above procedure for each axis requinng a home
referencé point
Once a home reference point has been established, the individual
intervals for multiple interval error compensation can be sel Alter
intervals have been established along an axis, the corresponding
error compensation values can then be anlered.
Before entering multiple interval error compensation values, it is
necessary to define interval boundaries or end points and how they
can be found. The boundanes for intervals are referenced within the
readout as 1 through 8. Each interval’s boundary location is referanc-
ed from the home reference point which has been selected for that
axis. The beginning of boundary 1 must be the mos! negative posi-
tion physically possible on the axis. With the beginning of boundary
1 established, all other interval boundary locations are determined
by entering the end points for each interval The end point of each
mierval is he beginning of the next interval
When using a manual technique to determine error values, the in-
terval and points should correspond 10 the crossing points of the
average error lines (best-fit straight lines). These positions can De
determined from the graph in relationship to the actual distance mov-
ed along the machine bed. The positions mus! be entered into the
error compensation table within the SET SYS mode, ERROR COM-
PENSATION Menu, of MILLVISION.
The following procedure is one easy way 10 establish boundaries tor
intervals based on the FTO home reference point position. This pro-
cedure results m the direct comelation between the position from gage
blocks and the prosition from the FTO.
1) Press the “SET SYSTEM" menu key
2) Press the "SET REF. POINT” menu key and find the home
reference point (refer 10 page 17 or 28 10 find the home reference
point).
3) Once the reference point is found, press thé “FINISHED” menu
key.
4) Press the |wæe| key.
The axis’ incremental register now displays position in relation
ship lo the home reference point (readoul position 0.000 being
the home reterénce point).
5) Move the axis until the incremental dispiay is 0.0000. Press the

MILLVISION
Wher using the automatic compensation routine, il is necessary 16
initially establish the approximate locations tor each interval into
which the axis is 10 be divided. These selected intervals (up to eight
intervals tor each axis) can be of any length It is assumed thar the
axis has a consistent error factor wilhin the specified area. Normal:
by, the area(s) where the majority of machining is done will be divid-
éd mto more mtervals than the unused areas. Approximaile locations
are required so the calibrated standard can be roughly centered on
each interval prior to being measured The actual interval boundaries,
as established by the auto amor compensation routing, are establish-
ed lor each interval at one-hall of the distance from the center of
ihe calibrated standard to the center of the calibrated standard as
localed and measured, in the adjacent interval.
In the auto compensation routing, a calibrated standard is measured
within each selected interval along the axis. For greater accuracy,
the calibrated standard should be no less than 15 of the length of
thar interval. The auto error routing will indicate the distance
measured (moved), and “ask” lor the aclual (calibrated) distance
moved. These numbers are used to calculate the error factor and
boundaries for a particular interval. The standard is then moved to
the center of the next interval and the procedure is repeated
To sat multiple interval error compensation, using either the manually
determined values or using the auto compensation feature, follow
these steps
1) In the SET SYS mode, press the “SET AXES” menu key
2) Enter password.
3) Press the "ERROR COMPENSATION" menu key.
4) Select the axis lo be programmed, by pressing an Axis key.
Note: The axis selected must have had a home reference
point previously established (see page 17 or 2B).
To place the interval boundaries and related error correction factors
(found through the error analysis described on page 20) directly into
the table through the EDIT routine. proceed as follows:
ba) Press the “EDIT” menu key.
6a) Starting with interval #1, prass the [| key
fa) Enter the end point location of interval #1 using Ing numeric
keys. The end point location = referenced from the home
reference point (FTO), Following example 23b, the end point
location {= 1.2310) is the position on the “Position Relative to
Home Reference Point’ line, where the first interval ends (the
dotted line Intersects the FTO line)
Ba) Using the arrow keys, move to the "PEM Comp” column and

and software copyright information. in addition, every time MILL VI-
SION is wmed on, a start-up routine is automatically executed which
checks information within its memory, checks HAM (Random Access
Memory) for successful battery backup and checks the expansion
slol module configuration for changes:
If MILLVISION's battery backup has tailed, it will perform some in-
ternal housekeeping in preparation for functioning. This preparation
defaults all software parameters to the factory default values (page

The upper 75% of the screen contains the following information:
ITEM A - individual Axis Label
MILLVISION is capabie of displaying up lo 4 axes of mo-
tion. These axes are labeled X,Y, Z, W.
ITEM B - Primary Axis Position, Incremental/Absolute
The axis position displayed In the primary display position
(larger numbers) can be either the incremental or absolute.
The relalive positions of the Iwo pieces of display infor-
mation are as indicated by Item K. The relative position
of the display (incremental/absolute) can be changed by
pressing the menu key opposite Item К.
MILLVISION
37
ITEM C - Secondary Axis Position, Incremental/ Absolute
The display in this position is eflfher incremental or absolute
information, depending où which is in the pnmary posi-
hon (see Пет В).
ABSOLUTE vs INCREMENTAL
MILLVISION axis information is displayed in two positional formats,
absolute and incremental
Absolute position represents the distance from the current tool poss-
tion to the workpiece zero position. Workpiece zero Is usually set
once at the star of machining a piece and not changed.
Incremental position represents the distance from the current too!
position to a desired tool position (point to point). Incremental posi-
tion is relative to values the operator presets into the display. These
presets can be the amount of movement required to go to the next
desired point, or may be the amount of distance Iraveled since the
incremental position was last reset to zero
ITEM D - individual Axis Status Display
This area contains information corresponding specitically
10 thal particular axis. It notes if the axis has been frozen,
etc. The different messages will be explained and expana-
ed upon as they are needed.
Items A, B, C, and D are the same for all axes being displayed on
the screen, The number of axes displayed depends on how the umi
is contigured in Setting the DRO display mode which is covered on
page 40
The size of the leners and numbers making up the information for
items A, B. C. and D is controlled by the number of axes beng
displayed If! three or less axes are being displayed, the information
will be in a large size format. If four axes are being displayed, the
information will be in a medium size formal. A typical three-axis and

The size of ina three-axis display 15 approximately 33% larger than
Me four-axts display. In both the larger and smaller formats. the
display consists of eight lull digits with the decimal points vertically
aligned for all axes on the screen. The common decimal pont posi-
hon is located 50 the axis with the highest resolution has all of its
decimal digits displayed to the right of the decimal point. If a number
is larger than can be displayed with the common decimal point, the
decimal point, for Inhalt axis only, shifts (0 the right. This will decrease
the axis resolution, but increases the magnitude of the number thai
can be shown
The lower portion of the DRO mode display contains general readout
status information:
ITEM E - Current DRO Mode & Current Program Step Number
The DRO mode that is currently selected — DRO mode
1 or DRO mode 2, This area also gives the current pro-
gram step number while a program is being “run” or
“Igared”.
ITEM F - Current Measurement Units
This section shows the current unit of measurement for
the displayed axis or axes. This information pertains fo
both angular ang non-angular axes. INCH or MM will be
displayed for non-angular axes. DMS (degrees, minutes,
seconds) or DEG (degrees) will be displayed for angular
axes
ITEM G - Current Active Tool Number
This display indicates the selected or current tool number
and Offset sion. This tool number comesponds to a specific
(col offset in MILLVISION memory. This information is us-
ed to computé movement compensation factors relative
to tool geomelry. The tool offset Sign indicates which side
of the point of cut the 100! center is located.

ITEM K - DRO Menu Key
MILLVISION
39
ITEM L - DRO Menu Key
lems K and L are the lwo menu keys available in the DRO mode
Their labeis change depending on the special DRO function currently
active
MILLVISION supplies two user-defined display modes: DRO display
mode 1 and DRO display moda 2 With two modes, the operator can The DRO mode
design two different display formats for machining, The operator
chooses information to be displayed and eliminates information that
is not needed. Each display mode is configured separately and can
have diferent resolutions, near zerg points, couplings, and number
ol axes.
The current DRO display mode is noted on the screen in the DRO
status area (Figure 27, Item E). To change the mode, press the DRO
key. This key toggles between the two DRO modes.
Note: If an axis is not being displayed, incoming information from
the encoder is still processed and maintained internally. There
is no loss of position information,
By setting different display resolutions for mode 1 and mode 2, the
operator car work in one display mode using a coarse resolution tor
rough cutting and the other display mode using a finer resolution
tor finish machining
The near zero feature gives the operator a visible indication of ap-
proaching zero. Whan the encoder moves into the programmed near Near zero display
zeró region, the axis label flashes until the incremental display Indicator
reaches zero, moves through zero, or the encoder leaves the near
zero region. The near zero feature is reactivated and reset when the
incremental display value is outside ot the near zero “boundary
The near zero region is valid for approaches made from either direc-
tion. The near zero warming is set while configuring the DRO display
modes as explained below
The DRO display modes are configured In the DRO mode and SET (
SYS mode with the special function keys and the menu keys. The Setting the DRO
areas thal must be configured are the axes to be displayed, display display modes

Multiple Scale Coupling (MSC) allows the capability of mathematically
combining the signals from two parallel linear encoders. The two en-
coder signals are electronically added, subtracted, or averaged to
display one resultant motion, relative to the workpiece
MILLVISION has three ways of performing Multiple Scale Coupling
between axes. Coupling can be done using the Set System mode,
the DRO mode, and/or the PROG mode.
Coupling established in the SET 5YS mode (SET DRO DISPLAYS
routine) can be displayed in any position of the DRO display. This
method of MSC remains in existence until changed in the SET DRO
DISPLAYS routine. The coupling can be added, subiracted, or
averaged.
MILLVISION
To establish multiple scale couplings in the SET DRO DISPLAYS
routine, proceed as follows:
Note: The following routing can ba programmed while setting
the DRO DISPLAYS modas, slep 4 on page 40
1) From tha SET SYS mode; press the “SET DRO DISPLAYS”
menu key.
2) Select the DRO display mode (1 or 2) in which coupling is to be
displayed.
3) Use the arrow keys to highlight the axis position selected to
display coupling. Press the [oe] key.
4) Press the =) key.

MILLVISION
Immediate coupling ls established with the AXIS CPLE key while
in the DRO and PROG Modes. An advantage of this method is
that coupling can be established and discontinued easily within
the DRO and PROG modes. Immediate mode coupling remains
visible only for the present DRO or PROG Mode. The coupling
is erased if the display is changed to another mode (including
another DRO mode). The coupling is nol erased when the HELP
mode is accessed.
Immediate multiple scale couplings include tha following limitations:
1. Only two axes may be coupled together.
2 The coupling musi be either addition or subtraction
3. Only one immediate mode coupling can be operational at a ime
An immediate mode coupling is displayed in the last axis position
in the DRO and PROG Mode screens. H there are four axes being
displayed, the coupling will override the fourth axis. The fourth axis
remains active and will reappear when the coupling is removed.
To establish immediate mode couplings, using the AXIS CPLE key,
proceed as follows:
1) From the DRO mode, or PROG RUN/LEARN, press Ihe | AE

2) Use me axis keys to select the first axis to be coupled.
3) Using the menu keys (ADD, SUBTRACT), select the coupling

4) Select me second axis 10 be coupled.
The immediate mode coupling can be erased al any time by chang-
ing the DRO display mode. leaving the DRO mode, or by pressing
the AXIS CPLE key. When the coupling is erased, the display con-
figuration (as it appeared prior to the coupling) will return. While pro-
gramming immediate coupling, the sequence can be aborted by
pressing the AXIS CPLE key.
With either method ol MSC, a coupling cannot be identified as a unk
que axis for presetting, edge finding or zero reselling. Presets,
however, made on an axis which is included in the coupling will af-
fect the coupling position
Mear zero indication capabilities remain active while axes are coup
ed. The near zero boundary for a coupled axes display, established
n the SET DRO DISPLAYS routine, is sel as pari ol that routine
The near zero boundary lor immediate mode couplings is sel lo zero

The display resolution for permanent couplings is set in the SET DRO
DISPLAY routine. The display resolution for immediate mode coupi-
ings is defined as the coarsest resolution of the axes being coupled

2) Select the "Multipliers" menu key
3) Highligh the desired axis with the arrow keys.
4) Erase the existing value with [ous key.
5) Enter the new value with the numeric keys
All displayed axes MUST have a multiplier. During normal
machining, the multiplier will be “1. No axis should have a value
of 0.
Multipliers are in eftect tor DRO display modes 1 and 2, but the PROG
mode requires multipliers be entered as part of the program (sée

MILLVISION was developed win a specific machining principle: Mach ini ng
always machining lo zero. By machining to zero, thé operator does
not have to remember a long number at which lo stop the cut. When to Zero
MILLVISION's incremental display reads zero, the movement has
pean completed.
MILLVISION makes machining to zerc possible by presetting the axis
displays. There are four different types of axis presefting: Absolute,
Incremental, Reference, and Zero Reset.
Absolute presetting changes "he absolute display to the entered value Absolute
and zéros the incrementa! display, Absolute presetting specifies the
distance from the current tool position to workpiece zero. In stan- presetting
dard machining, most operations are performed relative to workpiece
zero. Therefore, If it Is changed and nol indicated on the work print,
il could create confusion for the operator.

Axis presetting
procedures
Hetlerence presetting sets he mcremental display lo ie distance re-
quired to get 10 a position relative to the workpiece zero, rather than
trom the current position. Reference presetting automatically sub-
tracts the desired posilion from the current tool position. Example:
Assume the log! position in the X-axis i= located 6 inches in the
positive direction from workpiece zero, and the operator wants to
move it 50 that it is positive 8 inches from workpiece zero. The
operator would enter X (he axis key), 8 (the preset value) and REF.
Initially, the X-axis incremental display would read ’—2 inches”,
Hence, the X-axis table slide, must be moved in the positive direc-
tion to get to zero. When the move has been made, the incremental
display for the X-axis will read “zero” and the absolute display will
show “+8 inches’. When a REF preset is entered, the value of
the incremental axis is changed to show the distance needed
to achieve the reference preset position (the absolute axis is
unaffected).
The ZERO RESET key is a special key used with various presetting
functions. It is only used to preset the value of zero in the display.
Zero Resel 1s always used with either the absolute or the incremen-
tal preset function.
Zero Reset, when used with the incremental function, zeros Ihe in-
cremental display, but does not affec! the absolute display.
Zero Reset, when used with the absolute function, zeros both the
incremental and absolute displays at the same lime. Zero Resetting
the absolute display Is normally done only once on any workpiece
because It moves the position of workpiece zero.
Presetúng is a three step operation: an axis selection, presetfing a
value, and presetting a function. Amy of the following keystroke se-
quences can be used 10 preset an axis (or axés)
1) AXIS SELECTION, PRESET VALUE, PRESET FUNCTION
2) PRESET VALUE, AXIS SELECTION, PRESET FUNCTION
3) PRESET VALUE, PRESET FUNCTION, AXIS SELECTION
4) PRESET FUNCTION, PRESET VALUE, AXIS SELECTION
If axis selection 1s specified first in the sequence, the axis label will
appear in the axis presel area. If, however, the preset function is
specified first, its name (REF, ABS, INCA) will appear in the axis
presel area.
The preset value consists of up to eight digits (len spaces including
Ihe decimal point and sign) and may be entered with a maximum
of six decimal places, No more than one zero preceding the decimal
point may be used. The degree of accuracy of Ihe preset value (as
indicated by the number of digits to the right of the decimal point)
cannot be greater than the programmed resolution entered into the
SET SYS mode, SET PARAMETERS table at time of installation, If
a greater precision value is entered, it will be rounded off 10 match
the linear encoder or display resolution. Rounding oft will be deter-
mined and made lor each axis when using mulliple presets
MILLVISION
45
Orily one preset value and preset function can be used for any one
preset operabion, bul mora than one as can be selected. Each ans
selected lór a particular presetting function has its label displayed
Mm the axis preset area Multiple axis presets can be done while us-
ing sequences 1 and 2 (Seg axis presefting procedures on page 45),
when the axis selection lá not the last lem in the sequence. The
CLEAR key can be used to remove Ihe entire contents ol the preser
register,
When a number is entered info the preset register, 1! remains there
until another number is entered or If is cleared by the CLEAR key.
This means thal the last preset value may he reused (for example,
several holes located an equal distance apan) in subsequent preset
operations without having lo re-enter the value.
An angular preset can be made in DEG (degrees) or DMS (degrees,
minutes, seconds), I a single decimal point is used, it is assumed
10 be DEG (degrees); this is the standard input method. If the DRO
mode is in DMS units, a DMS preset can be made using multiple
decimal points
Example: 123.42.18 = 123° 42° 187
If only one decimal point is used It is assumed to be DEG input.
Example: 123.42 = 123° 25" 12"
The FREEZE function is used only mn conjunction with absolute
pressiting and zero resetting. The "FREEZE" menu key becomes The FREEZE
available whenever a preset operation is staned. This feature par- feature
mis the operator to select one or more axes and freeze” the cur-
rent display values, This is especially useful if the operator wants
to write down the current values on Ihe display without the risk of
changing them by bumping the table. It is also useful if the operator
wants to move the table cul ol the way to measure a cul and com-
pare it with the displayed value. When the freeze function is active,
it will maintain the frozen axes’ displays on the screen even if the
axes are moved. If the axes are moved, the information is not lost;
и is recorded and Ihe display is updated once the freeze has been
“thawed”, “cancelled", or a presel has been completed. When a
dispiay has been “frozen”, the "THAW" menu key will cancel the
operation. Incremental and reference presels can also be made to
frozen axes. but their net effect is as il it hadn't been frozen
An example of the FREEZE fealure with the absolute preset hunc-
ton is when an operator takes a trial cut and wants to sel tha X ab-
solute display to establish the initial dimension, Before moving the
tool away from the part, the operator would press the X-axis key,
then the "FREEZE" menu key. The X-axis would freeze its display,
thereby allowing the operator to pull the tool back without losing the
cutling position, Next, the operator would measure the part, enter
the dimension as a preset value, and press the ABS function key
The displayed position at which the "FREEZE" menu key was press-
ed, would be replaced by me entered preset dimension and the
display would become “unfrozen”. The lool would no longer be al
the culting position, but the current 100 position would be displayed,
considering the new location of workpiecs zero just entered
MILLVISION

The MIDPOINT
feature
е У 2 =
The MIDPOINT leature provides the operator with the means lo deler-
mine the midpoint or center of à particular part. In simple terms, it
presets the selected axis to one half of its current displayed value.
A manual edge hinder, lealer gage, or skim cutting operation can be
used to accomplish this. The readout does not require an electronic
edge hnder lor this feature
The MIDPOINT feature may be used to perform two forms of center
preselting; incremental and absolute. In the case of incremental mid-
points, only the incremental display is affected. With any absolute
preset, however, the absolute midpoint preset will affect both the in-
cremental and absolute displays. In either case, the affected displays
will read zero after successful completion of the MIDPOINT opera-
tion when the 1001 15 placed at the center,
To find the midpoint of lwo locations proceed as follows:
1) Move to the first point on the midpoint line.
2) Press the desired axis key,
3) Press the = key.
4) Press either the [mn] or [rss] key, This will zero the display al

For machinery operalions using various tools, it Is helptul to have
à means of referencing lool culting edges to a common tool point, Tool offsets
orto each other, for gach axis This reférencing process, called lool
offsets, can be used 10 update the unit lor a tool change. Updating
maintains the true position of the cutting surface in relation ho he
workpiece
The SET TOOL mode provides a quick and easy means to compen-
sale for the difference in dimensions of the tools to be used during
à particular machining operation Storing tool offsets in MILLVISION
frees the operator from manually presetting à compensation value
lor the selected tool. Tool offsets are nof cumulative — the effects
of tool offsets are always removed before being replaced by those
of a new tool.
Tool offset values are sat In the SET TOOL mode. To enter tool off-
sets proceed as follows:
1) Press the [fa] key
2) Use the “Edit Tool Offsets” menu key.
3) Usa the arrow keys to select the wal number and dimensión
(diameter and length). To jump to a tool number use the [*7]
key. There are 99 different tocl numbers available.
NOTE: Tool #0 is a default tool and always has dimensions of
zero. It cannot be assigned lool dimensions. There mus! always
be an active tool. However, the effects of tool offsetting can be remov-
ed by selecting tool #0,

The offset sign indicales which side of the point of cut the tool
cenler is located. Therefore, the loflowng question musi be
ansered to determine the offset sign: When machining at each
point, Is the center of the tool in the im the + or — direction or
centered, in relation to the edge of the cut which is being machin-
ed? See Figure 32.

MILLVISION's edge lind function provides the toflowing capabilities:
1) Standard Edge Find Function
2) Workpiece Positioning
3) Two Point Calculations
Please read the following notes pertaining to all three of the edge
find functions.
The edge find functions only work for one axis at a time. All other
axes maintain normal counting functions and are unaffected by
the edge find operation.
All edge find functions use tha ball radius and the length of the
edge finder as tool offsets”. It is very important, therefore, to
enter this information in the SET TOOL mode (see page 51)
The selection of a function, not related to the edge lind function,
Will cancel the edge find operation. The “CANCEL” menu key
also cancels the edge find operation
The edge find operation can be aborted at any time by pressing
the EDGE FIND kéy
The X and Y tool offset signs are automatically updated ac-
cording to the direction the edge finder was moving when
the touch occured. The offset signs can be edited at any time
during the edge find operation. If the ‘Manual Touch”
method is used, the offset signs mus! be selected manually.
By manually entering the offsets, the position displayed is
at the edge of the ball (not the center).
i All edge find functions use the ball radius and the langth of the edge
Entering edge finder as "tool offsets”. This information must be entered in the SET
finder offsets TOOL mode
To enter edge finder offsets, proceed as follows:
1) Press the [=] Kay.
2) Press the “Edit Edge Finder Offsets” menu key.
3) Enter the ball diameter. This value can beé either mchas or

MILLVISIONs program capabdites offer the abdity to machine
repetitive parts easily and efficiently A program displays the infor.
mation the operator requires to machine a part without relermng back
to a print. Program memory can hold 8 programs with a total of 250
steps.
Programming is comprisad ol 3 functions:
Programming - contains routmés to enter new programs, view
entered programs, edit existmg programs, and erase old programs.
Running a Program - Enlered programs are run in [he PROG mode.
While running a program, every step involves the operator machin-
ing lo zero
Learning a Program - allows the operator to enter a program by
machining a part. Subsequent paris can then be machined with the
learned program by running the program (above).
All presets applicable to an operation, conform to the philosophy of
machining 10 zero. With this idea, the machining opération is not com-
plate until the displays read zero, This eliminates the possibility of
Ihe machinist getting lost during an operation — the constant known
destination is always zero.
When crealing a program, each axis is programmed with 8 multiplier.
This is useful whan machining mirror images or allowing for differ-
ing expansion and contraction factors. All real numbers {positive or
negative), up to six digits to the right of the decimal point, can be
used as a multiplier. It is important that The multiplier value |s never
Zero.
Examples:
1) When working from a full size, scaled drawing, a multiplier of
“1” must be used.
2) When machining a mirror Image part, a multiplier of ” — 1” would
be used.
3) To machine a part one hall the size of the drawing, a multiplier
of “5" is used.
ZW coupling is a feature thal couples (mathematically combines)
the Z and W axes while running or learning a program. The operator
no longer needs to preset each axis to make a combined movement.
To set Z'W coupling while creating a program, proceed as follows:
1) Press the [roc] key.
2) Move the highlight bar to the desired program (or create a new
program) and press the “EDIT NAMED PROGRAM" menu key.
3) Move the highlight bar to the “ZW Coupling:"' function, Press
the desired function — "OFF", “"Z+W", or "Z-W".
To cancel the ZW coupling, the operator mus! edit the program and
repeal the steps above. The function must be "OFF".

While using Z/W coupling there are a few things to note:
While running or learning & program, the 7 ana W axes will not have
individual axis displays
A manual MSC can be used in addition to the ZW coupling (see page
43)
While learning a program.
All presets are recorded as the couplings absolute position and
IS learned as a Z presel,
The near zero value ls Sello zero. and the display resolution Ls
sel to the coársesl of Me Z and W encoder resolutions.
While running a program:
Na preser is made to either the 2 axis or W axis, IT will affect
tha coupled display:
The near zero and display resolution values are laken from the
last Z or W preset in the program step
Each program step contains seven arsas ol information:
Axis - Each slap can be programmed for two axes, each with a
separate preset, function, round off value, and near zero flashing
point. However, only axes which are lo be machined with the same
too! can be used in the same step.
Preset - A presel is a machined dimension from the work print (draw-
ing) thal is programmed into memory. YWhen incorporating into a pro-
gram, presets operate the same as in the DRO modes 1 and 2. In
a step, however, a presal may refer Io Ihe previous step (1.e currant
tool position) or 10 any previous step in the program.
Function - Function refers to the ABS. INCA, and REF function keys.
These keys represent the type of move the preset value represents.
ABS refers to an absolute preset which moves workpiece zero.
Absolute presets can be made In a program, but usually
it is nol advised because of the loss of the original
Wworkp-ece zero.
INCA ls an incremental move which represents the distance
from the present locatien 10 the next desired point,
REF is a relerence move which is the distance from the end
point of the reference step indicated, to the next desired
point. It REF function is used, ne step 4 of the referenc»
ed point must be indicated. A reference step to workpiece
zero is indicated as REF O
NOTE: Zero Reset incremental can be used to remove
incremental tolerance build-up on the display. At the
same time, however, it bullds up tolerances on the
part.

Round Off - The round off value Ihe resolulion displayed for this
step. The displayed resolution, however, should never be finer than
the encoder resolution. A round off value is defined lor each axis
in the step
Flashing - Flashing indicates the near zero value. This value sers
the boundaries for tha near zero display indicator (see page 40). Each
axis 1s assigned à value
Auto Step - Auto step links the next step with the current step. This
makes It possible to display four axes of molion on the screen
simultaneously. When auto step is active, the linked second step
overwriles all previous information from the first step, except for dit-
ferent axes and display variables (presel, function. round oli, flash).
It Ils important that the linked steps use Ihe same tool number. Be
careful that the same axis is nol programmed in both Steps, because
the second programmed presel will overwrite the first preset
Tool Number - This is used fo reference the tool numbers as pro-
grammed in Ihe Tool Offset Table (see page 45). The too! number
must also indicate and offset sign (=, —. +). To determine the off-
sel sign, the following question must be answered: When machin-
ing al each point, is the center of the tool in the + or — direction,
or centered in relation to the edge of the cut which is being
machined?
Thé default offset sign is =* indicating the tool is centered. This oft-
sel is used when drilling holes. To change the offset sign press the
+/— key to toggle between =, -, and +.
The step presets are modified by the too! offsets. Make sure ofisets
have been programmed in the SET TOOL Mode for the mois chosen
in a step.

isting program, thal program must be highlighted in the PRO-
GRAM DIRECTORY.
Highlight he desired program name
Press the "RUN OR LEARN PROGRAM" menu key.
Highlight the word “LEARN” (menu key).
Toleam a program, the operator machines a pan using presets
to set the displays. Each time a machining operation is com
pleted, the NEXT STEP key should be pressed. MILLVISION
automatically enters the distance between the culling surface’s
current position and the workpiece zero location for each axis
(for all the axes that have moved). The values are used to create
program reference presets for each step. The presets are entered
inte the program step as reference presets (referenced from the
absolute zero of gach axis) Al the same time the presets are
entered into memory, the current tool number is also entered,
with the current measurement units. Only axes that have mov-
ed will be used to create a new step.
Note: I! the operator wishes to display axes which are not
part of the current step he must move the axis and retum
it to where it was, so MILLVISION records a movement made
with that axis. H more than two axes have changed since the
last step entry, the first two axes which showed movement
will be used to create the next program step. The remainder
of axes indicating movement within that display will be us-
ed to create a subsequent step. This activates the Auto Step
feature to link the two steps. The same tool number will be
used for both steps.
Once the NEXT STEP key has been pressed, the operator is
ready to begin the next machining operation. Continue his pro-
cess until the pan is completely machined.
Iris recommended that absolule presets and absolule zero resers
not be used. These presets move workpiece zero which may
cause improper execution of subsequent learned steps.
Exit the "LEARN" routine by selecting "RUN" or pressing a
mode key.
Once a program is leamed in the "LEARN" rouline, It can be
run, viewed, edited, or deleted (see pages 63-64).

with the printer, computer or remote storage device connected Pro. Sett ng p otocols
locois define the handshaking and the way data 5 exchanged bel
ween MILLYISION and the external device, To sel these prolocols,
follow the procedure below:
1) Press the SET SYS key and then the "OPTION-MODULE CON-
FIGURATION™ manu key.
2) Press the “RS-232 PROTOCOLS" menu key
3) Press (he desired port — “Port 1” or “Port 2",
4) Use the arrow keys to move through the protocols and make the
appropriate choice for each handshaking field An explanation
of each protocol s described below. To exit he "RS-232 PRO-
TOCOLS" screen, press a mode key.
Baud Rate
Baud rate is the speed al which information will travel over He com:
munitation link. Although MILLVISION allows very asi baud rales
(up to 19,200 bits/second) there is à point which the system
throughput will no longer increase with faster baud rates — faster
is not always better.
MILLVISION can process information at a relatively fixed rate, If
MILLVISION cannot process the information as fast as Il is coming
in, one of two things will occur
1, М по handshaking is used, input bulter overfiow will occur,
and MILLVISION will produce a System Error
2. If handshaking is used, MILLVISION will tell” IHe other
device to stop sending data until it can catch up.
For most applications, MILLVISION's optimum baud rate is 1,200
bits/secand. Speeds higher than this will nor significantly improve
performance. The chosen baud rate must be the same as the device
interfaced.
Parity
Party is a form of error checking on the received data. When data
is transmitted, an additonal bit of Information is attached. This bit
is checked at the receiver, and if it is incorrect, an error condition
is flagged. MILLVISION can be configured lor three ot the most com-
mon forms of parity (even, odd, of none). The chosen type of parity
mus! be the same as the device interfaced,
Data bits
Since ASCII information is being transterred, only seven data bits
are required. Some devices, however, require eight data bits
Therefore, MILLVISION is configurable for either, The chosen
number of data bits must be the same as the device interfaced.
Stop bits
Stop bits signity the end ol a piece of data Only one is required,
with MILLVISION, unless the interfaced device requires two. Both
devices must be configured lor the same number of stop bits

XON/XOFF
XONIXOFF is à form of software handshaking Handshaking is a
method of controlling the flow ol information so the receiving device
will be ready for incoming information when it arrives. If the receiv-
ing device is not ready, it must tell the transmitting device not 1o send
anything for a while. This is accomplished with the XONIXOFF pro-
tocol, If a device is nol ready to receive, it sends an XOFF character
to tell the other device nol to send any data. When it is ready to pro-
cess more information, il sends an XON character to tell the other
device "it is ok to send now”.
If this protocol is enabled, both devices must be capable ol transmit-
ting and responding 10 the XON/XOFF characters.
Hardware Handshaking Signals
Pins 4, 6, 7, and 6 on each serial por are hardware handshaking
signal ines. Hardware handshaking performs the same task as soft-
ware handshaking, but in a different manner,
The signals on pins 4 and & are handshake signals that allow each
device to tell the other device it is available for communications. Pin
4 is an output for MILLVISION thal, when active {logical "0", + 12V),
signals the remote device thar MILLVISION is available for com-
munication. The signal on pin 6 is an input to MILLVISION that, when
active (logica! “0”. + 12W, indicates to MILLVISION that a remote
device is connected to the other end of the serial cable and that the
remote device is ready 10 communicate.
Note: MILLVISION requires an active (logical "0", + 12V), signal
on pin 6 to enable It to communicate with another device. If the
attached device does not provide such a signal, it will be
necessary to wire pin 4 to pin 6 on the MILLVISION end of the
serial cable. This jumper will provide the necessary signal on
pin 6 to allow communications.
The signal on pin 7 is an output trom MILL VISIÓN that can be describ-
ed as “ready lo receive". When this outpul is active [logical "0",
+ 12V). it signifies that MILLVISION is ready for incoming informa-
tion When MILLVISION cannol accepl more data, il sets this out-
put inactive (logical “1”, —12V).
The signal on pin 8 is an inpul to MILLVISION. When the signal is
active (logical "0". + 12V), MILLVISION knows that it can send data.
when the signal is inactive (logical “1"", — 12V), It tells MILLVISION
lo “shut up". The handshake signal is ignored if "CTS" Is designated
as inactive in the protocols for that port in “SET SYS", "RS-232
PROTOCOLS".
Hardware vs software handshaking
Both types of handshaking address the same problem: regulation
of data flow. Using both hardware and software handshaking is
redundant, but the system will work with both (assuming the other
device supports both methods). At low baud rates, handshaking may
not be required al all. Al higher baud rates, the system will fail unless
some form of handshaking is used.
MILLVISION
The form of handshaking the operator chooses, depends on the
device mierfaced. Some devices are only capable of one form of
handshaking, either hardware or software. MILLVISION's oplion
module was designed lor flexibiliy, allowing either form of handshak-
ing. MILLVISION must be configured to the same form of handshak-
ing as the device interfaced. Il the interlaced device does nol sup-
port either form of handshaking, slower baud rates must be used.

The following pin outs are examples of interfacing PCs with a S-pin

NOTE: THE MILLVISION CHASSIS COVER SHOULD NEVER BE i
REMOVED FROM THE UNIT — THERE IS NOTHING WITHIN THE T roubleshooting
CHASSIS THAT CAN BE FIELD SERVICED.
MILLVISION is equipped with an electricaly powered exhaust fan i 7
lor the dissipation of internally generated heal, and features a Ventilation
passive, fillered, fresh air Intake, Adequate airflow to the intake SYSTEM
should be allowed lor, as well as accessibility to replace the filter
assembly, | necessary.
It MILLVISION's infernal temperature rises above a presei imi, a
message will appear on the screen (when in the DRO mode). This
message will direct the operator to select the HELP screen for
remedial action,
WARNING - Whatever the reason for the diagnostic filter
message, It is Imperative that the unit be shut down and the
fault rectified as soon as possibie (the immediate machin-
ing operation may be completed).
“Check Filter" Faults and Remedies
1) Inadequate airflow to the filtered intake - Make sure paper,
wipes, or debris are not restricting air circulation around and
under the unir.
2) Plugged Filter - The fan filter is easily removed for cleaning or
replacement. Simply unsnap the protective culer quard from the
main fan assembly. Clean the filter with soap 4 water (let dry
belore reinstalling). Replacement filters are available from ACU-
RITE Factory Service (1-800-832-3222).
3) Work area temperature too high - MILLYISION is designed to
function in a temperature range of 0° to 40° C (32% to 104" F)
with 25-85% relative humidity, non condensing. If the work area
temperature ls too high, it is recommended that MILLVISION be
shut down until temperatures retum to the normal operating
range.
4) Exhaust fan does not operate at high temperatures - The ех-
haust fan only runs when internal temperatures are high, If the
“Check Filter” warning is present, indicating high internal
temperatures, and the fan is not wing do nol continue to
operate: MILLVISION, Excessive internal temperatures can
damage the electronic components, Contact your ACU-RITE
Distributor/OEM or the Factory Service Department

follows
1} Press the SET SYS mode key
2) Press the "MISCELLANEOUS" menu key.
3) Press the “TESTS” menu key.
4) Press the "HARDWARE IDENTIFICATION” menu key
The module revision numbers will be useful when discussing a pro-

I! a problem arises within MILLVISION, error messages and help to
recover Irom Ihe error appear on the screen,
Possible errors in dala transmission from one module to another and
encoder performance include:
ERR T1 - Module (axis) transmitting invalid dala
ERR T2 - CPU Module transmitting invalid data
ERR T3 - Previously identified module falls to communicate
ERR T4 - Invalid data request
ERR C1 - Invalid pulse counting
ERR C2 - Encoder output signal is out of spec
ERR C3 -Invalid encoder input signal, lor inose axes with differen
tial input option
"T™ Errors are sell-corecting (up to a certain level), The system will
attempt to remedy the condition several limes before prompting tha
operator,
ERR T1 and ERR T2 wrap errors from partial communicalion hard-
ware breakdowns and from cernain communication soliware errors.
If a bit gets dropped during a data transfer, or if an axis board {ails
to recognize a dala request code, the error message results.
ERA T3 appears if the module is removed while the unit is operating
or if there is a communication hardware failure. This error will also
appear Il the software fails to interface with the communication
hardware,
**C"" Errors involve the axis board encoder pulse circuitry and sofl-
ware, These errors are no! self-correcting and must be ramedied by
the operator (through an error recovery routine) or an ACU-RITE
serviceman,
ERR C1 is a soliware error “trap”. H occurs II the axis board
microprocessor is unable to access the pulse counting circuitry (keep-
ing current encoder position), or if tha circuitry fails 1o count correct
ly. This error may be corrected by resetting the axis board In ques-
tion. It should, however, be interpreted as a serous error and the
axis board serviced or replaced.
MILIVISION

ERR C2 i= a hardware error generated by the axis board encoder
Input circuitry. This electronic circuit constantly monitors the integri-
ty ol the encoder signal lor slew spaeds greater than the unit can
accommodate. Incorrect pulse train sequence or electro-magnetic
interference (noise) will make the unit count incorrectly, These pro-
biems are outsidé the readout and require the operator to first cor-
rect Me external problem and then resell tha axis board.
Error messages note the error Type, the slot location of the devianl
module, and the particular axis the error has occurred.
Most error codes can be réset by restarting the axis board in ques- Resetting
lion. This is done through the "ERROR RECOVERY" menu key
which becomes active in the DRO display once an error has occurred. EFTOr COdes
Press Ihe “ERROR RECOVERY" menu key lo restan an axis board.
À screen indicating the axis board and encoder connection in error,
possible reasons Ihe error occurred, steps to recover from the armor,
and requirements are displayed.
Press the “FIX AXIS" menu key to restart the axis in question. A
note will appear indicating il he error was removed successiully or
unsuecessfuly. Il {he error was removed sucocessiully, the axis board
is resel and the problem is no longer present. If the error was not
removed successfully, the problem is sill present and further
troubleshooting must continue, The problem may be a faully module
af in the linear encoders.
Note: If a home reference point is used (FTO or Absolute Zero
scales), "C'' type errors require that it be found again.
If 2 hardware faull is suspected (axis board, CFU board of power
