The Encoder resolution settings available should match the resolution of the encoder being used with the
NMS100 digital unit. If this resolution is set incorrectly the display measurement provided on the display
will be incorrect, usually by a large amount.
It is important that the inch/mm setting corresponds to the resolution that is required to be used, if the
resolution of the encoder is metric the mm setting will need to be in use. The inch/mm setting can be
changed while in the encoder resolution setup menu.

The digital readout (DRO) system helps to improve productivity. It decreases the number of scrapped
parts, as there is no concern about making mistakes related to counting the revolutions on the dials. The
DRO system also helps to eliminate some errors related to ball-screw backlash.
The DRO system will operate to its published accuracy, provided all components are in working order and
properly installed. Field calibration is not necessary.
Accuracy problems with machined parts may be caused by machine error, installation inaccuracies, or
a combination of both. The rst step in determining the source of error is to check the DRO system. To
do this compare the movement of the reader head to the position reading shown on the display. A high
accuracy standard, such as a laser interferometer is required. A dial indicator can be used to check short
distances, but a laser provides the best results. If a dial indicator must be used, be sure it is the highest
available accuracy.
To check the accuracy of the DRO system:
1. Place the target of the laser or the needle of the dial indicator directly on the reader head. It is abso-
lutely critical that the readings are taken directly from the reader head. If a dial indicator must be used, be
sure that the needle of the indicator is perpendicular to the reader head and not angled. If readings are
taken anywhere else on the machine, machine errors may distort the results.
2. When the reader head moves, the movement registers on the laser / indicator and DRO display.
3. Set the laser / dial indicator and DRO position displays to 0.
4. Make a series of movements and compare the position readings between the laser / dial indicator and
the DRO display. If the readings match within the accuracy specied, it proves that the DRO system is op-
erating properly. If this is the case, proceed to the next step: evaluating the machine errors. If the readings
do not match, the DRO system must be repaired before proceeding with error compensation.

Error Compensation Continued
Types of Machine Error
Linear Error Compensation
To evaluate machine errors:
1. Put the laser target / dial indicator on the part of the machine where the machining is done.
2. Make a series of movements and compare the position readings between the laser / dial indicator and
the DRO display. The di󰀨erence between the laser / dial indicator reading and the reading on the DRO
display is the machine error.
3. Plot the machine error along the entire axis of travel to determine the nature of the error. If it is a linear
error, use linear error compensation.
There are many types of machine error, including pitch, roll, yaw, atness, straightness, and
Abbé error. The diagrams below demonstrate these errors.
Error compensation

Way errors
Abbé error
There are three settings for each axis:
Press the Select Key next to the ‘XX’, ‘YY’ or ‘zz’ to cycle through
these settings.
Once you have set the error compensation you want to use on
all the axes, press the down navigation key. The middle display
changes to ‘EErrrrSSEEtt’.
If you set one or more axes to Segmented Error
Compensation, or Linear Error Compensation, then your
next set up option is to configure the compensation for each of
those axes.
If you apply Error Compensation, then you must ensure that it
is absolutely correct. If it is not correct, then errors could be
increased rather than reduced.
Once you have set up the Error Compensation, we advise you
to check its effect in normal operation.
Segmented error compensation
In this mode, you can break down the scale travel for each axis
into as many as 99 user-defined segments, with each segment
having its own correction factor. The correction factors are

In this mode, a single constant correction factor is applied for each axis for all displayed measurements.
Calculate the correction factor, and specify it in parts per million (ppm).
When following the procedure ensure that a stepped standard is used, and approach each edge from the
same direction; or if each edge must be approached from opposite directions, then subtract the width of
the tool or measuring probe from the value displayed on the NMS300.

Program mode allows the linear compensation to be calculated manually and then entered as a PPM val-

The procedure to do this is shown below:
To illustrate the calculation an example is being used where the standard distance is 500.000mm and the
measured distance is 500.200mm.
Correction factor = error / actual x 1,000,000
Correction factor = (500.000 - 500.200) / 500.000 x 1,000,000
Correction factor = -400 PPM
