Connection details
Important Details
The NMS100 is only compatible with Newall Spherosyn Serial and Microsyn Serial encoders. During the install it is important to ensure that:
- Secure all the cables to prevent the connectors from dropping into hazardous positions (for example the floor or coolant tray) when they are unplugged.
- Route all cables to prevent them from being caught on moving parts.
- The NMS100 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. Do not connect this unit directly to the mains supply.

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,
installation inaccuracies, or a combination of both. The first 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.
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 specified, 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, flatness, straightness, and Abbé error. The diagrams below demonstrate these errors.
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.

RS232 Output Data Format
The output data for the RS232 is as follows;
The current axis data for the axes available on the system in transmitted.
The data Packet structures of 12 characters is defined as follows:
The Axes ID is the representation of the axis at the time of printing. This will be shown by the legend set for the axis at the time.
Trouble shooting guide
Symptom | Solution |
---|---|
The display is blank | • The NMS100 may be in sleep mode. Press any key to exit |
sleep mode
• Check that the power supply is correctly connected to a working mains outlet
• Check that the power supply cables are not damaged
• Check that the power supply voltage is 15 – 24Vdc ±10%
The display works, but resets from time to time without any keys being
pressed.| Either the supply voltage is too low, or the power supply or mains
supply has an intermittent fau
• Check that the power supply voltage is 15 – 24Vdc ±10%.
• Check that all the connections are secure.
The display works, but gives erratic readings, the last digit jitters or the
measurements jump to new figures unexpectedly.| There may be a poor earth
(ground) connection. Both the NMS100, and the machine on which installed, must
have proper earth (ground) connections.
There may be a problem with the encoder.
The unit does not respond to any key presses.| Disconnect the NMS100 from its
power supply, wait 15 seconds and then reconnect.
‘NO Sig’ / ‘SIG FAIL’ or ‘1.x’ appears in the display.| This indicates that
the unit is not receiving a proper signal from the encoder.
• Check that the encoder connections are secure.
• Check that there is no damage to the connectors or to the encoder.
• Switch the NMS100 off and back on again.
| Readings are incorrect.
• Check the Encoder Type to ensure it is correct.
• Check the Radius / Diameter setting. The Diameter setting causes the axis to
read double.
• Check the Error Compensation factors.
• If using the Segmented Error Compensation, verify the datum position.
• Check that there is no damage to the encoder or its cable.
• Check that the encoder is fixed firmly and aligned correctly, as described
in the Spherosyn /Microsyn Installation manual.
• Check that there is no binding on the scale. With the scale brackets
slightly loosened, you sho be able to slide the scale back and forth with
minimal resistance.
• If a Spherosyn scale is in use, check that the scale is not bent, by
removing it and rolling it on a flat surface.
If the solutions suggested above do not solve the problem, contact Newall for further instruction.
To swap encoders to trace a fault:
1. Check that the axis is set to the correct encoder types.
2. Disconnect the NMS100 power supply.
3. Disconnect the encoder from the malfunctioning axis and move to a working
axis.
4. Reconnect the NMS100 power supply and turn on.
If the fault stays with the same encoder, then the encoder is at fault. If the
fault does not follow with the encoder the NMS100 is at fault.
Providing the machine has not been moved more than 6.3mm (0.25”) for a
Spherosyn encoder or 2.5mm (0.1”) for a Microsyn encoder,
switching the power off and back on again does not lose the datum position.
