RMP400 basics
2.1
Introduction
The RMP400 offers an unrivalled combination
of size, accuracy, reliability and robustness
and, allows high-accuracy probing on small to
medium machining centres or other machines
where line-of-sight problems affect optical signal
transmission.
Successfully combining patented RENGAGE™
strain gauge technology with the patented
frequency hopping radio transmission system of
the RMP40, the RMP400 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;
Performing this calibration for every 3D
direction can be time-consuming.
The RMP400 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:
The auto-reset function is required and
recommendations should be followed for
optimum metrology performance.
Getting started
Three multicolour probe LEDs provide visual
indication of selected probe settings.
• a proven ten-fold improvement in life (10 million
triggers); ????
• 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 RMP400
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.
For example:
• Switch-on and switch-off methods
• Probe status – triggered or seated
• Battery condition
Batteries are inserted or removed as shown (see
page 3.5, “Installing the batteries”) for further
information).
On insertion of batteries, the LEDs will begin
to flash (see page 4.1, “Reviewing the probe
settings”).
Page 12
System interface
Draft 5 16/04/18
Configurable settings
The RMI and RMI-Q are integrated interfaces/
receivers used to communicate between the
RMP400 probe and the machine control.
RMP400 basics
2.2
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.
A Trigger Logic app is available that simplifies this
process with clear, interactive instructions and
informative videos and is available for download
on the following app stores.
Switch-on/switch-off methods
The following switch-on/switch-off options are
user-configurable.
• Radio on/Radio off
• Radio on/Timer off
• Spin on/Spin off
• Spin on/Timer off
or
Current probe settings can be reviewed by
simply removing the batteries for a minimum of
seconds, and then replacing them to activate
five
the Trigger Logic review sequence.
Pr
obe modes
The RMP400 probe can be in one of three modes:
Standb
signal.
NOTE: The RMP400 will enter hibernation mode
should the system interface be powered off or
out of range for a period of 30 seconds (only
applicable to “radio on” mode).
y mode – Probe is waiting for a switch-on
Operational mode – When activated by one of
the switch-on methods, the probe is switched on
and ready for use.
Configuration mode – Ready to change the
probe settings using Trigger Logic.

2.5 seconds. (The
probe must be
stationary for 2.5
seconds minimum
after it has stopped
spinning.)
NOTES:
In “radio on” mode, the switch-on time is user
selectable “fast” or “standard” when using
RMI-Q (selection is made in RMI-Q). Otherwise
1.7 seconds.
For more information on the user selectable
switch-on time when operating with RMI-Q, please
refer to the installation guide RMI-Q radio machine
interface (Renishaw part no. H-5687-8504).
In “radio on” mode, the switch-on time assumes
a good radio communication link. In a poor RF
environment this may rise to a maximum of
3.0 seconds.
In “spin on” mode, the one second starts from
the moment the spindle reaches 500 rev/min.
The RMP400 must be on for a minimum of
one second before being switched off.
Page 14
RMP400 installation guide
Draft 5 16/04/18
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.
RMP400 basics
2.4
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, then 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 RMP400
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 long,
a 0.2 second dwell is necessary. In most
applications the machine response time will
adequately provide this.
Up to four RMP400s can be used with a single
RMI-Q in “radio on/radio off” mode. For further
details of this functionality, please refer to the
installation guide RMI-Q radio machine interface
(Renishaw part no. H-5687-8504).
NOTES:
Multiple probe mode is a function of the RMP400,
as such, the option will not appear when the
“radio on” option has been selected.
RMP400 probes which are set to “multiple probe
mode on” can coexist alongside any number of
RMP400 probes set to “multiple probe mode off”.
To allow multiple radio probes to work in close
proximity, and with a single RMI or RMI-Q,
16 choices of “mode on” colours are available,
each representing a different machine tool
installation. (see page 4.2, “Multiple probe
settings”).
All probes operating with a single RMI or RMI-Q
must be set to the same “mode on” colour choice;
any multiple probes located on adjacent machines
must all be set to an alternative “mode on” colour
choice.
NOTE: Each probe per “mode on” colour choice
needs to be partnered with the RMI or RMI-Q.
By configuring multiple probes to a single “mode
on” colour choice, all probes using this “mode on”
colour choice will have the same identity.
When using a heavy stylus configuration, or a
stylus longer than 150 mm, it is recommended
that the RMP400 should be turned off during
reorientation moves.
Multiple probe mode
The RMP400 can be configured, using Trigger
Logic, to allow multiple radio probes in “spin on/
spin off” or “shank on/shank off” to be used with a
single RMI or RMI-Q.
The probe to be partnered is partnered after
selecting the multiple probe mode setting and
choosing the “mode on” option. (see page 4.4,
“Changing the probe settings”).
There is no limit to the number of probes that can
be used with a single RMI or RMI-Q so long as
they all have the same “mode on” colour choice.
All RMP400 probes are factory set to “mode off”.
The addition of any further probe(s) into a single
probe installation will require that all probes are
reconfigured to the same “mode on” colour choice
and that one of the probes is then repartnered
with the RMI or RMI-Q.
Page 15
The addition of any further probe(s), or
Draft 5 16/04/18
replacements, into a multi-probe installation can
be achieved simply through the reconfiguration of
the probe to the same “mode on” colour choice.
Acquisition mode
System set-up is achieved using Trigger Logic and
powering-on the RMI or RMI-Q.
Partnering is only required during initial system
set-up. Further partnering is only required if either
the RMP400 or RMI/RMI-Q is changed.
NOTES:
Systems using the RMI-Q can be partnered with
up to four RMP400s manually. Alternatively this
can be achieved by using ReniKey; a Renishaw
machine macro cycle which does not require the
RMI-Q to be power cycled.
RMP400 basics
2.5
For more information or to download ReniKey free
of charge visit:
www.renishaw.com/mtpsupport/renikey
Partnering by ReniKey is not available for RMI.
Partnering will not be lost by reconfiguration of
probe settings or when changing batteries, except
where multiple probe mode is selected.
Partnering can take place anywhere within the
operating envelope.

The featured range of solid carbon fibre styli
ensure the best possible performance of the
RMP400.
It is possible that the featured range of solid
carbon fibre styli may not be suitable for every
RMP400 application and that 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
probing moves. It has been seen in some cases
that specialist styli configurations do not exhibit
the probing characteristics and performance
that would have otherwise been expected and
achieved when using standard styli. Reducing the
speed of the probing move may, in some cases,
improve the performance of the probe.
A-5003-6510
Carbon fibre
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 with a short length
and reduced diameter is selected.

via reflected paths, and will pass through gaps
and machine tool windows. This allows easy
installation, either inside or outside the machine

The probe system should be positioned so that
the optimum range can be achieved over the full
travel of the machine’s axes. Always face the front
cover of the RMI or RMI-Q in the general direction
of the machining area and the tool magazine,
ensuring both are within the performance
envelope shown below. To assist in finding the
optimum position of the RMI or RMI-Q, the signal
quality is displayed on an RMI or RMI-Q signal
LED.
The RMP400 has a built-in hibernation mode
(battery-saving mode) that saves battery life
when the RMI or RMI-Q is unpowered in radio-on
(radio-off or timer-off) configurations. The RMP400
goes into hibernation mode 30 seconds after
the RMI or RMI-Q is unpowered (or the RMP400
is out of range). When in hibernation mode, the
RMP400 checks for a powered RMI or RMI-Q
every 30 seconds. If found, the RMP400 goes
from hibernation mode to standby mode, ready for
radio-on.
Performance envelope
The RMP400 and RMI or RMI-Q must be within
each other’s performance envelope, as shown
below. The performance envelope shows line-ofsight performance, however, this is not necessary
for the RMP400 radio transmission as it will
operate with any reflected radio path provided
that the reflected path length does not exceed the
15 m (49.2 ft) operating range.

Calibrating the RMP400
Draft 5 16/04/18
Why calibrate a probe?
A spindle probe is just one component of the
measurement system which communicates with
the machine tool. Each part of the system can
introduce a constant difference between the
position that the stylus touches and the position
that is reported to the machine. If the probe is
not calibrated, this difference will appear as an
inaccuracy in the measurement. Calibration of the
probe allows the probing software to compensate
for this difference.
Calibrating in a bored hole or on a turned diameter
Calibrating a probe, either in a bored hole or on
a turned diameter of known size, automatically
stores values for the offset of the stylus ball to
the spindle centre line. The stored values are
then used automatically in the measuring cycles.
Measured values are compensated by these
values so that they are relative to the true spindle
centre line.
Calibrating in a ring gauge or on a datum sphere
System
3.7
installation
During normal use, the difference between the
touch position and the reported position does
not change, but it is important that the probe is
calibrated in the following circumstances:
• when a probe system is to be used for the first
time;
• when the enhanced trigger filter delay is
changed;
• when a new stylus is fitted to the probe;
• when it is suspected that the stylus has
become distorted or that the probe has been
crashed;
• at regular intervals to compensate for
mechanical changes of your machine tool;
• if repeatability of relocation of the probe shank
is poor. In this case, the probe may need to be
recalibrated each time it is selected.
It is good practice to set the tip of the stylus oncentre, because this reduces the effect of any
variation in spindle and tool orientation (see page
3.6, “Stylus on-centre adjustment”). A small
amount of run-out is acceptable, and can be
compensated for as part of the normal calibration
process.
Calibrating a probe either in a ring gauge or
on a datum sphere with a known diameter
automatically stores one or more value for the
radius of the stylus ball. The stored values are
then used automatically by the measuring cycles
to give the true size of the feature. The values are
also used to give true positions of single surface
features.
NOTE: The stored radius values are based on the
true electronic trigger points. These values are
different from the physical sizes.
Calibrating the probe length
Calibrating a probe on a known reference surface
determines the length of the probe, based on
the electronic trigger point. The stored value for
length is different from the physical length of the
probe assembly. Additionally, the operation can
automatically compensate for machine and fixture
height errors by adjusting the probe length value
that is stored.
Three different operations are to be used when
calibrating a probe. They are:
• calibrating either in a bored hole or on a turned
diameter of known position;
• calibrating either in a ring gauge or on a datum
sphere;
• calibrating the probe length.

Master reset function
RMP400 features a master reset function to assist
user’s who have mistakenly changed the probe
settings into an unintended state.
The application of the master reset function will
clear all current probe settings and return the
probe to default settings.
The default settings are as follows:
• Radio switch-on
• Radio switch-off
• Auto-reset on, Enhanced trigger filter on 8 ms
• Hibernation mode on 30 s
• Multiple probe mode off
The default settings may not be representative of
the required probe settings. Further configuration
of RMP400 may subsequently be necessary to
achieve the required probe settings.
To reset the probe
1. First enter into the Trigger Logic™ menu and
ensure that the stylus is no longer deflected.
2. From within the Trigger Logic menu, hold the
stylus deflected for 20 seconds. After this
the status LEDs will proceed to flash yellow
eight times. A confirmation for master reset
is required, if nothing is done the probe will
timeout.
To confirm that a master reset is required,
release the stylus and then hold the stylus
deflected again until the eight yellow flash
sequence has ended. This action will clear
all probe settings and return the probe to
default settings. Following an LED check the
RMP400 will then go back into Trigger Logic
and will display “Switch-on method”.
3. Further configuration using Trigger Logic may
be necessary to achieve the required probe
settings.
1. Probe is in the Trigger Logic menu.
Ensure that the stylus is no longer deflected.

Whilst the status LEDs are flashing yellow to confirm that
a master reset is required, release the stylus and then
hold the stylus deflected again until the eight yellow flash
