Important Details
Secure all the cables to prevent the connectors from dropping into hazardous positions (for
example the oor or coolant tray) when they are unplugged.
Route all cables to prevent them from being caught on moving parts.
The NMS300 is grounded to the machine, using the braided grounding lead provided, before
the machine supply is turned on.
The power has been disconnected, before the encoder(s) are connected.
The NMS300 is only compatible with Newall Spherosyn 300 and Microsyn 300 encoders.
It is important to ensure that:
Do not connect this unit directly to the mains supply.
If an encoder connected to the NMS300 travels over 3.2m an error code (20000) will be displayed in the X
axis and the other axes will go blank. See the trouble shooting guide for further details on page 34.

Error Compensation
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, DRO system error, or a com-
bination 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 Newall 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.
Setting up the unit

11
Error Compensation Continued
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 Newall reader head. It is
absolutely critical that the readings are taken directly from the Newall 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.
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 difference 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. If the error is not linear, use segmented error compensation.
Types of Machine Error
There are many types of machine error, including pitch, roll, yaw, atness, straightness, and
Abbé error. The diagrams below demonstrate these errors.
Error compensation
5-5

Way errors
Abbé error
There are three settings for each axis:
Press the Select Key next to the ‘X’, ‘Y’ or ‘z’ 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 ‘Err SEt’.
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

Linear Error Compensation
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.
Linear Error Compensation Setup
This setting allows the setup of compensation factors for linear errors. There are two methods of entering
compensation values Teach mode and Program mode.
Teach Mode
Teach mode is an easier way of calculating linear errors by using the NMS300 to automatically calculate
the error. This is achieved by comparing the actual measurement and the physical movement.
The procedure to do this is shown below.
Navigate to the Error compensation selection screen

Program Mode
Program mode allows the linear compensation to be calculated manually and then entered as a PPM val-
ue into the NMS300 display.
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
To enter this value into the display:
Navigate to the Error compensation selection screen

Segmented Error Compensation
The scale travel is broken down into as many as 200 user-dened segments, each with their own correc-
tion factor, measured against a high-accuracy standard. The following parameters need to be identied:
Each Correction Point is measured with respect to the Starting Point - zero - which is usually set close to
one end of the scale. The Reference Point can be set anywhere along the scale, and does not need to
coincide with either the absolute datum or any of the correction points.
However, it may be convenient to make the absolute datum and the reference point the same.
Always approach the Starting Point, Correction Points and Reference Point from the same direction. If
not, then the size of the tool or probe will render the measurement inaccurate.
