Installing the Readout

Follow the readout installation instructions that are included with your
mounting arm bracket kit. The electrical specifications for the readout
are listed on pg. 28.

Installing the Scales

Please see the manual included with the scale for installation instructions.

Power Up

Press the switch on the back of the readout to power up the system. A
series of tests will check that the display, keypad, and memory are all
working properly.

If a problem is detected, an error code will appear on the screen. (Error
messages and solutions are listed on pgs. 26 - 27.) It is important to
note that the E1 message will appear every time you power up your
system and does not indicate a problem. It merely indicates that the
system had lost power. To acknowledge the message, press the CLEAR
key and proceed to the DRO mode.

Note:

If the E1 message appears at any other time during normal
operation, refer to pg. 26 for possible problems and solutions.

When the system is not used for more than 90 minutes, a decimal point
will “scroll” across the X-axis display, indicating that the display saver
has been activated. The display saver, like a screen saver on a computer
monitor, will help prolong the life of your readout.

If the display saver has been activated, press any key on the readout or
move any axis to return to the normal DRO view.

SETUP

There are five to six parameters that you can define on your system:

• Display resolution (diS)

• Linear error compensation (LEC)

• Scale resolution (rES)

• Scale count directions (Ct dir)

• Input 3 ON/OFF (InPUt 3) 2+ units only

• Position Recall (recall)

Establish each setting the first time you power up the system. You can
change the parameters later by returning to Setup and then using the
ENTER key to scroll to the appropriate category.

Anytime you change the linear error compensation, or count direction
for an axis, the absolute and incremental displays for that axis will be
reset to 0. If you change these settings, you’ll need to reestablish the
datum point.

When in the Setup mode, use the CLEAR key when you want to back­space, restore the previous value or access the previous parameter.

Parameter Setup

SETUP

The display resolution determines how detailed each scale’s position
will be displayed on the readout. Use the setting that best suits each job.

Display Resolution

To change the display resolution:

• Press the SETUP key. (“diS” will show on the display.)

• Press the

X or Z key for the display you want to change.

For 10µm scales, the display resolution will toggle between 0.01 mm
(0.0005”) and 0.02 mm (0.001”). For 5µm scales, it will toggle
between 0.005 mm (0.0002”) and 0.01 mm (0.0005”). For 1µm scales,
it will toggle between 0.001 mm (0.00005”) and 0.002 mm (0.0001”).

• After you complete setting your display resolution, press ENTER to
continue with setup or press ENTER then SETUP to return to the nor­mal DRO display.

SETUP

Linear Error Compensation

With 100S, you can compensate for machine tool wear. If you know the
linear error compensation (LEC) value in parts-per-million (PPM), you
can enter it directly.

If you don’t know the LEC, use the formula on the next page to determine
the value for each axis.

• Move to the “Linear Error Compensation” display in the Setup
mode. (Press SETUP and then the ENTER key until “LEC”
appears).

• Press the

X or Z key for the axis you want to change.

100S will display the current LEC value for that axis.

• Using the keypad, enter the linear error compensation factor
(in PPM), followed by the ± key for negative values. The number
must be within -9999 and 9999 (use whole numbers). The formula for
calculating the value is on the next page.

• After you complete setting your LEC, press ENTER to continue with
setup or press ENTER then SETUP to return to the normal DRO
display.

• In the DRO mode.

• Place a standard of known length on the machine. Make sure it’s
parallel with the axis being measured.

• Put the readout in the absolute display mode (

ABS/INCR key).

• Using an indicator, locate one end of the standard.

• Press the

ZERO key twice for the axis you are measuring.

“0” should appear on the display.

• Move the indicator along the axis until it reaches the opposite
end of the standard.

• Write down the length that is shown on the readout display for
that axis.

• Use the formula below to calculate the LEC for the axis you just
measured. Enter the result in the LEC parameter (previous page).

How to Determine the Linear Error Compensation

Follow this procedure for each axis:

• Move to the “Count Direction” display in the Setup mode. (Press
SETUP and then the ENTER key until “Ct dir” appears).

• Press the appropriate axis key (

X or Z). The current count direction

(1 or 2) will appear.

• After you complete setting your count direction, press ENTER to con­tinue with setup or press ENTER then SETUP to return to the normal
DRO display.

To change the count direction:

Count Direction

Use the count direction setting to define the positive counting direction
for each scale. The direction will be displayed as a “1” or a “2” (the
numbers are not assigned to a particular direction). You only need to
change the count direction if the scale is counting in the negative
direction during a positive move, or vice versa.

Refer to Conventions on pg. 32 for more guidelines.

SETUP

Scale Resolution

To ensure accurate readings, the scale resolution shown for each axis must
correspond with the resolution of the scales on your machine.

T

o change the scale resolution:

• If necessary, choose “Scale Resolution” from the Setup menu.
(Press SETUP and then the ENTER key until the screen appears).

• Press the appropriate axis key (X, Y or Z) until the appropriate resolu­tion appears. Choose 0.01 mm for 10µm (0.0005”) scales, 0.005 mm
for 5µm (0.0002”) and 0.001 mm for 1µm (0.00005”)scales.

• Repeat the procedure for each axis.

• Press

ENTER to continue with Setup.

Input 3 On/Off (2+ units only)

This parameter allows you to activate the third input. When this input
is enabled, Inputs 2 and 3 will be coupled on the Z-axis (both scales
will count on the Z-axis). The Input 3 scale must have the same scale
resolution as the Input 2 scale.

When Input 3 is enabled, additional parameters will need to be setup.
Refer to the procedures on pages 6-8 for setting up the Linear Error
Compensation and Count Direction Setup functions.

Position Recall

• Set this parameter to the ON position to store the last position
of each axis when power is turned off.

Testing the Scales

Follow these steps to confirm that the scale has been installed properly.
The Counting Test will confirm the scale’s electrical operation, and the
Repeatability Test will check the installation integrity.

Counting Test

• Move the table along each axis, one at a time. Check that the
readout correctly displays the table’s movement. If it doesn’t,
then the scale resolution you selected may not be accurate. Refer
to Scale Resolution, pg. 9.

Repeatability Test

• Locate a magnetic base and dial indicator on the end of the scale.
Zero the readout and the indicator.

• Move the axis through the full travel and return the dial to “0.”
The readout should also read 0 (±0.0005” for 10µm scales;
±0.0002” for 5µm scales; ±0.00005” for 1µm scales). If it
doesn’t, then the scale cable may be loose, or the scale, mounting
bracket, or reading head may need to be tightened or realigned.

• Repeat these steps for each scale.

100S Turning Reference Manual

OPERATION

Reference Mark Evaluation

ENC 125 encoders contain internal reference marks, approximately 4"

apart along the length of the encoder. These marks enable you to easily
re-locate your correct position after a power interruption. You relocate
your position, relative to the last established datums, by traversing across
one reference mark on each encoder. You must find a convenient refer­ence mark on each encoder prior to establishing your datums, and then
use those same marks during the evaluation procedure, after a power
interruption, to re-establish your position relative to your datums.

To perform Reference Mark Evaluation:

• Move near the appropriate reference mark.

• Press and hold the

DECIMAL key until the decimal points on the

displays start to flash

• Move slowly past the reference mark until the readout recalls its
position.

• Repeat for each axis.

Power On Position Recovery

With the 100S there are two means of position recovery, Position Recall
and Reference Mark Evaluation.

Position Recall

When this feature is active (see setup parameters) the last displayed posi­tion is stored in memory when power is lost or turned off. When power is
restored, the stored position is recalled and displayed.

Note:

Any movement that occurs while power is off will be lost.
Whenever power has been off it is recommended that you re­establish workpiece datums using the Reference Mark
Evaluation procedure below).

Radius and Diameter

Pressing the RAD/DIA key lets you view the X-axis dimension either as
a radius or as a diameter.

Display resolution is affected by the RAD/DIA key.

13

100S Turning Reference Manual

OPERATION

Setting the Datum (Absolute Zero)

100S allows you to measure both absolute and incremental dimensions.

A dimension measured from the point you define as the datum is an
absolute dimension. A dimension measured from any other point on
your print is an incremental dimension.

Datum, also known as absolute zero or workpiece zero, is the reference
point from which

100S will base all of your part’s coordinates. When

the readout is in the ABS mode, it is actually measuring the distance
from the datum to the machine axis’ current position.

You will need to establish a datum for every job. Your datum may
already be identified on your print; if it isn’t, then establish a datum that
allows you to measure most of your part’s dimensions directly, with the
least number of calculations.

All of the dimensions in the drawing below are based from the datum.

100S Turning Reference Manual

OPERATION

14

• Using the ABS/INCR key, select the absolute (ABS) mode. Also
check that the proper measurement (inch or mm) is selected.

• Using RAD/DIA key, select the Radius mode.

• Move the tool to a known point, i.e. the outside diameter of the
workpiece or the face of the workpiece.

• Press the ZERO key once for the axis (X or Z) for which you are
entering a dimension.

• Using the keypad, enter the distance from your tool’s current
location to the point you want to establish as the datum. Include a
decimal point (.) and minus (-) sign when necessary.

• Press the ZERO key for the other axis, or press ENTER to return
to the DRO display.

To set the datum using an offset:

To set the datum at the tool’s current position:

• Position the workpiece in the chuck. Move the tool until
it is positioned at the location where you would like to establish the
datum.

• Using the ABS/INCR key, select the absolute (ABS) mode.

• Press the X-axis

ZERO key twice to establish the current X-axis

position as the datum. Repeat for the Z-axis.

OPERATION

As we described earlier, incremental dimensions are measured from the
current tool position. If your tool is currently at 2” and you want to
move an additional 3.125”, you would select the incremental mode,
zero out the axis, and move the axis until the display reads 3.125.

An example of how to measure using incremental dimensions is shown
on the next page.

• Move the machine axis to the point from where you want to
measure an incremental distance.

• Use the ABS/INCR key to select the incremental (INCR) mode on
the readout. Also check that the proper measurement (inch or mm)
is selected.

• Press the

ZERO key below the axis(es) from which you are measur-

ing.

• Move the machine axis.

100S will display the machine

axis’ position in relation to the incremental “0” point(s) for the
axis(es) you chose.

After you have reached the position you want and have machined the
part, you can “zero” each axis again and then measure from that loca­tion to the next point on your workpiece or press ABS/INCR to return
to the absolute mode.

To use an incremental dimension

Example: Incremental Dimensions

Let’s say that your print looks like this:

1. Ensure you are in RAD mode (DIA LED
will be off).

2. Move the tool until the readout display

shows that the X-axis = 1.0000” and
the Z-axis = 2.0000” in the absolute mode.

3. Press the ABS/INCR key to switch to the

incremental mode.

4. Press the X-axis ZERO and the Z-axis

ZERO keys.

5. Begin cutting until the X-axis reads -0.1200”.

Using Incremental Zero

In order to cut a groove to a depth
of 0.120” from the 1” radius, it is
necessary to establish a zero at 1”.
This can be done using the incre­mental mode without changing the
Datum. Follow these steps:

Using Incremental Dimension Presets

In addition to setting incremental zero at the current
tool position, you can also preset the incremental
zero from the current tool position. Enter the dis­tance and direction you wish to move in relation to
your current position. Follow these steps:

1. Ensure the DIA LED is off

2. Move the tool until the readout display shows that the
X-axis = 1.000” and the Z-axis = 2.0000” in the absolute mode.

3. Press the ABS/INCR to switch to the incremental mode.

4. Press the X key ensure the INCR LED is lit and press the following

key sequence: - . 1 2 ENTER.
