2.1
OMP600 basics
Introduction
Welcome to OMP600, Renishaw’s optical probe that offers an unrivalled combination of size, reliability,
robustness and high-accuracy probing on medium and large machining centres.
Successfully combining patented RENGAGE™ strain gauge technology with the optical transmission
system of the OMP60, the OMP600 provides existing probe users with a simple upgrade to solid-state
strain gauge technology and all the associated benefits this brings:
• excellent 3D performance to allow probing of contoured surfaces;
• improved repeatability in all probing directions;
• a low triggering force combined with low pre-travel variation to provide high accuracy, even when
used with long styli;
• the elimination of reseat failures;
• high resistance to machine tool vibration;
• resistance to shock and false triggering through the use of solid-state accelerometers.
In addition to providing high-accuracy measurement on your machine tool, the OMP600 also offers:
• Faster calibration:
On complex 3D parts, it is common to measure in several different directions. Each direction
of a standard mechanical probe must be calibrated, to ensure that the pre-travel variation is
compensated in the measurement. Performing this calibration for every 3D direction can be
time-consuming.
The OMP600 has almost no pre-travel variation, so a single calibration value may be used for any
probing angle in 2D or 3D. This results in a vastly reduced calibration time. An additional benefit is a
corresponding reduction in errors introduced by environmental changes within the machine during
a long calibration cycle.
• The ability to be used in applications where axial and radial reorientations are used, enabled by the
use of solid-state accelerometers.
NOTE: The auto-reset function is required and recommendations should be followed for optimum
metrology performance (see “Auto-reset function” later in this section).

OMP600 installation guide
2.2
OMP600 basics
Getting started
Three multicolour probe LEDs provide a visual indication of the selected probe settings.
For example:
• switch-on and switch-off methods;
• probe status – triggered or seated;
• battery condition.
Batteries are inserted or removed as shown (see “Installing the batteries” in Section 3, “System
installation” for further information).
On insertion of the batteries, the LEDs will begin to flash (see “Reviewing the probe settings” in
Section 4, “Trigger Logic™”).
Modulated vs legacy optical transmission
The OMP600 can be operated in either modulated or legacy mode. Modulated mode has a higher
resistance to light interference. Certain forms of light interference can cause false triggers or mimic
a start signal and falsely activate the probe. These effects are much reduced when modulated
transmission is selected.
Modulated mode
When set to modulated mode, the probe will only function with the OMI-2, OMI-2T, OMI-2H and
OMI-2C interfaces, or with the OSI with OMM-2 interface system.
Legacy mode
When set to legacy mode, the probe will only function with an OMI or OMM with MI 12.
Multiple probe system
To operate a twin OMP600 probe system, one OMP600 probe needs to be set to PROBE 1 start and
the other to PROBE 2 start. In applications where a third OMP600 is to be used, this should be set to
PROBE 3 start. These settings are user configurable.
The Renishaw OMI-2T interface allows twin OMP600 applications. The Renishaw OSI with OMM-2
interface system allows up to three OMP600 probes to be used on the same machine tool.
NOTE: When used in conjunction with an OMI-2T, or with an OSI with OMM-2 interface system, the
OMP600 switch-on method must be set to “optical on” (standard).
Trigger Logic™
Trigger Logic™ (see Section 4, “Trigger Logic™”) is a method that allows the user to view and select
all available mode settings in order to customise a probe to suit a specific application. Trigger Logic is
activated by battery insertion and uses a sequence of stylus deflections (triggering) to systematically
lead the user through the available choices to allow selection of the required mode options.

2.3
OMP600 basics
A Probe Setup app is available that simplifies this process with clear, interactive instructions and
informative videos and is available for download on the following app stores.
or
Current probe settings can be reviewed by simply removing the batteries for a minimum of 5 seconds,
and then replacing them to activate the Trigger Logic review sequence.
Probe modes
The OMP600 probe can be set in one of three modes:
Standby mode: where the probe is awaiting a switch-on signal.
Operational mode: activated by one of the switch-on methods described later in this section. In this
mode the OMP600 is ready for use.
Configuration mode: where Trigger Logic may be used to configure the following probe settings.
Configurable settings
Switch-on delay
When the standard switch-on is selected, the probe will be operational in less than 0.8 seconds. After
being switched on, the OMP600 must remain operational for a minimum of 1 second before being
switched off.
A second switch-on mode is available whereby a 3 second delay is invoked after the probe start
signal is received. This feature is aimed at machines where “auto-start” is required, i.e. it will ensure
that when the probe receives a start signal during a tool change that it will switch on correctly in
the spindle. To ensure that the probe activates correctly, it is important that it is stationary when it is
switched on. If the probe is not stationary during a start sequence, there is a possibility that the strain
gauges could auto-zero in the incorrect position and produce a permanently triggered output. The
3 second delay ensures that the start sequence only occurs when the probe is safely located in the
machine spindle (this assumes that the tool change process is completed in less than 3 seconds).
NOTES: The probing program on the machine will need to take account of the 3 second delay.
The 3 second delay is not compatible with the OMI-2T or OMI-2H.
When used in conjunction with an OSI with OMM-2 interface system, the OSI should be set to single
probe mode.

NOTE: A visual indication of currently selected probe settings is provided, on battery insertion, by the
three multicoloured LEDs located within the probe’s window (see Section 4, “Trigger Logic™”).
NOTE: After being switched on, the OMP600 must be on for 1 second before being switched off.

2.5
OMP600 basics
Enhanced trigger filter
Probes subjected to high levels of vibration or shock loads may output signals without having
contacted any surface. The enhanced trigger filter improves the probe’s resistance to these effects.
When the filter is enabled, a constant 8 ms or 16 ms delay is introduced to the probe’s output. The
factory setting is 8 ms. If false triggering is noticed, consider increasing the filter delay to 16 ms.
Auto-reset function
In previous strain gauge products, the probe was required to be turned off during reorientation moves.
The auto-reset function in the OMP600 can compensate for stylus forces, resulting from changes in
probe orientation, that can cause the probe to trigger.
This feature is controlled by solid-state accelerometers and is suitable for applications where axial and
radial reorientation of the probe is applied.
To achieve optimum metrology performance when the auto-reset function is turned on, a dwell is
recommended before making a programmed move that follows any reorientation of the probe.
When using a stylus of up to 150 mm in length, a 0.2 second dwell is necessary. In most applications,
the machine response time will adequately provide this.
When using a 200 mm long stylus, or heavy stylus configurations, a 1 second dwell is required. This
will necessitate edits to the machine probing programme.
When in “auto-reset” mode, the probe will not trigger when moved below a speed of 3 mm/min.
NOTE: Speeds below 3 mm/min commonly occur when manually moving the probe using the
handwheel with a very ne feedrate.
Optical transmission modes
Probes subjected to particular forms of light interference may accept spurious start signals.
The OMP600 can be operated in either “Modulated” or “Legacy” optical transmission mode.
Modulated mode
The OMP600 becomes compatible for use with the OMI-2, OMI-2T, OMI-2H, OMI-2C and OSI with
OMM-2 interface sytem to provide substantially increased resistance to light interference.
Modulated transmission, in the OMP600, is capable of providing three different coded start signals.
This allows the use of two probes with an OMI-2T and up to three probes with an OSI with OMM-2
interface system, respectively.
Legacy mode
A start filter improves the probe’s resistance to spurious start signals.
When Legacy (start filter on) is enabled, an additional 1 second delay is introduced to the probe
activation (switch-on) time.
It may be necessary to revise the probe program software to allow for the increased activation time.

Twin or multiple probe system
To operate in a twin or multiple probe system, one probe needs to be set to PROBE 1 start and the
other to PROBE 2 start (OMI-2T or OSI with OMM-2 interface system) or PROBE 3 start (OSI with
OMM-2 interface system only). These settings are user configurable.
In a twin probe system, such as a spindle probe and an optical tool setting probe, the spindle probe
would be set to PROBE 1 start and the tool setter to PROBE 2 start.
In a multiple probe system, with two spindle probes and one optical tool setting probe, the two spindle
probes would be set to PROBE 1 and PROBE 2 start, respectively. The tool setter would be set to
PROBE 3 start.
Optical power
Where the separation between the receiver/interface is small, low optical power may be used. In this
setting, the optical transmission range will be reduced, as shown on the performance envelopes, so
battery life will be extended.
Dotted lines on the performance envelopes represent the OMP600 in low optical power.
Low optical power should be used whenever possible for increased battery life.
Maximum battery life is achieved when lithium- thionyl chloride (LTC) batteries are used in conjunction
with low power mode.
The probe is factory set to standard optical power.

Note 1 Performance specication is tested at a standard test velocity of 240 mm/min (9.45 in/min). Signicantly higher velocity
is possible depending on application requirements.
Note 2 Trigger force, which is critical in some applications, is the force exerted on the component by the stylus when the
probe triggers. The maximum force applied will occur after the trigger point (overtravel). The force value depends on
related variables including measuring speed and machine deceleration. RENGAGE™ equipped probes offer ultra-low
trigger forces.
Note 3 Stylus overtravel force in the XY plane typically occurs 126 μm after the trigger point and rises by 0.32 N/mm,
33 gf/mm (29.3 oz/in) until the machine tool stops (in the high force direction and using a carbon bre stylus).
Note 4 Stylus overtravel force in the +Z direction typically occurs 50 μm after the trigger point and rises by 2.95 N/mm,
301 gf/mm (270 oz/in) until the machine tool stops.

High-modulus carbon fibre styli are designed to minimise pre-travel and improve accuracy, as the stem
material is extremely stiff. This inherent stiffness makes the following styli the most suitable for strain
gauge applications.

Use of the solid carbon fibre styli featured above will guarantee the best possible measurement
performance from the OMP600.
It is possible that the recommended styli may not be suitable for every OMP600 application and it may
be necessary to select specialised styli configurations to meet specific application requirements.
In applications where specialised styli are to be used, it may be beneficial to reduce the speed of any
probing moves. It has been observed that, in certain circumstances, specialist styli configurations will
not exhibit the probing characteristics and performance that would have otherwise been expected and
achieved when using the recommended styli. Reducing the speed of the probing moves may, in some
instances, improve the performance of the probe.
When selecting components for an application-specific stylus, it is recommended that a configuration
with the least number of components is chosen. The stylus diameter should always be as large as
possible and the overall stylus length kept to a minimum. If a stem with a reduced diameter is required,
then it is recommended that an M4 stem of short length and reduced diameter is chosen.

Operating envelopes
When used with the OMI or the OMM with MI 12 or MI 12-B, the OMP600 uses legacy transmission.
When used with the OMI-2, OMI-2T, OMI-2H or with the OSI with OMM-2 interface system, the
OMP600 uses modulated transmission.
Natural reflective surfaces within the machine may increase the signal transmission range.
For best system performance, ensure that the OMI-2C is mounted in a position which is not directly in
front of a light source.
Coolant and swarf residue accumulating on the probe, interface or receiver windows will have a
detrimental effect on transmission performance. Wipe clean as often as is necessary to maintain
unrestricted transmission.
CAUTION: If two systems are operating in close proximity to each other, take care to ensure that the
signals transmitted from the OMP600 on one machine are not picked up by the receiver on the other
machine, and vice versa. When this is found to be the case, it is recommended that the OMP600 low
optical power setting is selected, along with the low range setting on the receiver.

Performance envelope when using the OMP600 with an OMI-2, OMI-2T, OMI-2H or OMM-2
(modulated transmission)
The diodes of the OMP600 and the OMI-2, OMI-2T, OMI-2H or OMM-2 must be in each other’s field
of view and within the performance envelope shown. The OMP600 performance envelope is based on
the optical centre line of the OMI-2, OMI-2T, OMI-2H or OMM-2 being at 0° and vice versa.
