System performance
System performance
RMP60 and RMP60M have identical user options and radio performance
Operating envelope
Radio transmission does not require line-of sight
and will pass through very small gaps and
machine tool windows. This allows easy
installation, either inside or outside the machine
enclosure.
Coolant and swarf residue accumulating on the
RMP60/M and RMI may have a detrimental
effect on transmission performance. Wipe clean
as often as is necessary to maintain unrestricted
transmission.
When operating, do not touch either the RMI
cover or the probe glass window with your hand,
as this will affect the performance.
Operation in extremes of temperature will result
in some reduction in range.
RMI position
The probe system should be positioned so that
the optimum range can be achieved over the full
travel of the machine axes. Always face the front
cover of the RMI in the general direction of the
machining area and the tool magazine, ensuring
both are within the operating envelope.
To assist in finding the optimum position of the
RMI, the signal quality is displayed on an RMI
signal LED.
Note: RMP60/M in radio-on configuration
The RMP60/M has a built-in hibernate mode
(battery saving mode) that saves battery life
when the RMI is unpowered in radio-on
(radio-off or time-off) configurations.
The RMP60/M goes into hibernate 30 seconds
after the RMI is unpowered (or the RMP60 is
out of range).
When in hibernate, the RMP60/M checks for a
powered RMI every 30 seconds. If found, the
RMP60/M goes from hibernate to standby,
ready for radio-on.

Multiple probe mode
Multiple probe mode
RMP60 can be user configured using trigger
logic to allow multiple RMP60s to be used
with a single RMI.
Note:
Radio turn on cannot be used in multiple probe
mode.
To allow multiple probes/single RMI in close
proximity, 16 choices of ‘mode-on’ colours are
available – each representing a different
machine tool installation. The choices are
shown on the next page and in ‘Changing
probe settings’.
All probes on a single RMI machine should be
set to the same ‘mode-on’ colour choice; any
multiple probes on adjacent machines should
all be set to an alternative ‘mode-on’ colour
choice. Multiple probe mode will not appear in
the configuration of the probe if radio turn on
has been selected.
Only one of the multiple probes per machine
will need partnering as, by configuring multiple
probes to a single ‘mode-on’ choice, all probes
have the same identification. The probe to be
partnered, is par tnered after selection of
multiple probe on in ‘Changing probe settings’.
There is no limit to the number of probes that
can be used with a single RMI as long as they
all have the same ‘mode-on’ colour choice.
All RMP60s are factory-set to ‘mode off’.
The addition of further probe(s) into a single
probe installation requires all probes to be
re-configured to the same multiple probe
‘mode-on’ choice and the repartnering of
one of the probes to the installed RMI.
The addition of further probes (or replacements)
into a multi probe installation is achieved simply
by reconfiguration to the same ‘mode-on’
colour choice.
Note:
Any number of RMP60s set to ‘mode-off ’ can
be used alongside RMP60s set to ‘Multiple
probe mode’.

RMP60-RMI partnership
RMP60-RMI partnership
System setup is achieved using trigger logic and
powering on the RMI.
Trigger logic is a method that allows user
configuration of the options available in the
RMP60. Trigger logic uses a sequence of
RMP60 triggering and battery inser tion followed
by further RMP60 triggering.
This leads the user through a series of choices,
allowing selection of the required options.
Reviewing of choices can be made by battery
insertion alone. See Reviewing probe settings.
To par tner an RMP60 and RMI
Partnering is only required during initial system
set-up. Further partnering is only required if
either the RMP60 or RMI is changed.
Partnering will not be lost by reconfiguration
of probe settings or when changing batteries.
Partnering can take place anywhere within the
operating envelope.
1. Use trigger logic to access the RMP60
configuration mode.
2. Configure the turn on method (if not
configured).
3. Configure the turn off method (if not
configured).
4. Enter the acquisition mode by deflecting
the stylus.
5. Remain in ‘Acquisition Mode Off’ by not
releasing the stylus. This allows time to get
the RMI ready for partnering.
6. Power on the RMI.
7. Watch the RMI signal LED; after a couple
of seconds the LED will repeatedly flash on
and off green. This is the start of a 10
second interval in which the RMI is in
acquisition mode.
continued on next page
RMP60-RMI partnership
23
8. Release the RMP60 stylus and trigger it a
couple of times. This causes the RMP60 to
go into (and out of) acquisition mode.
9. The RMI signal LED will change to
repeatedly flashing red and yellow (for the
remainder of the 10 second interval),
indicating a successful partnering.
10. Leave the RMP60 for 20 seconds to go
into standby.
11. The system is ready to use.
Note
To check that turn on and off settings have not
accidentally been changed, remove and insert
batteries to review the current probe settings.
Note
When holding the RMP60, do NOT wrap a
hand, or anything else, around the glass
window.
Note
When the RMP60 and RMI become partners
the RMI records the RMP60 identity. It is not
possible for an RMI to be partnered with more
than one RMP60 in ‘Standard Mode’ - see
Multiple Probe Mode.
It is possible for an RMP60 to be partnered
with more than one RMI, but the system will
not function correctly.

RMP60 batteries
RMP60 batteries
Replacing batteries
Only use specified batteries.
Clean and dry the RMP60 with a cloth or paper
towel before removing the battery cover. Where
the RMP60 has been exposed to coolant, it is
recommended that the area around the battery
cover is cleaned.
To access the RMP60 batteries, remove the
battery cover by rotating the securing screw 30°
anticlockwise and withdraw the battery cassette.
Take care to avoid damaging the cover gasket.
When inserting the batteries, ensure they are
loaded as shown (see next page).
If one or more batteries are incorrectly loaded
the probe will not respond.
Do not mix new and used batteries or battery
types, as this will result in reduced life and
damage to the batteries.
Always ensure that the cover gasket and mating
surfaces are clean and free from damage before
reassembly.

Battery specification
The RMP60 requires two identical AA size
batteries, individually rated at a voltage of
between 1.2 V and 3.6 V.
The standard batteries are AA alkaline.
Alternative batteries are lithium thionyl
chloride (3.6 V), Nickel Cadmium (NiCd) or
Nickel Metal Hydride (NiMh).
Rechargeable batteries: either Nickel Metal
Hydride (NiMh) or Nickel Cadmium (NiCd)
can be used. Expect a battery life of
approximately 50% of alkaline figures.
For applications requiring maximum battery
life, a high capacity lithium thionyl chloride
type is essential.

probe relative to the shank, in the X or Y
direction, as pressure is applied.
Tighten individually, backing off after each
movement.
8. When the stylus tip run-out is less than
20 µm, fully tighten screws B to 6 - 8 Nm
(4.4 - 5.9 lbf.ft).
9. For final centering, use screws A to move
the RMP60, progressively slackening on one
side and tightening the opposite screw, as
the final setting is approached, using two
hexagon keys.
Tip run out of 5 µm (0.0002 in) should be
achievable.
10. It is important that all four screws A are tight
or tightened to 1.5 - 3.5 Nm (1.1 - 2.6 lbf.ft)
once the final setting has been achieved.

Stylus trigger force and adjustment
Stylus trigger force and adjustment
Spring force within the probe causes the stylus to sit in a unique
position, and return to this position following each stylus deflection.
Stylus trigger force is set by Renishaw. The user should only
adjust the trigger force in special circumstances, e.g. excessive
machine vibration or insufficient force to support the stylus weight.
To adjust the trigger force, turn the adjusting screw anticlockwise
to reduce force (more sensitive) or clockwise to increase
force (less sensitive). A stop prevents damage, which
could be caused by over-tightening the adjusting screw.
Stylus trigger force
Z direction
5.30 N / 530 gf (18.69 ozf)
X/Y direction (50 mm stylus)
X/Y trigger forces vary, depending on trigger direction.
There are 3 high force and 3 low force X/Y directions:
Factory setting for low force direction = 0.75 N / 75 gf (2.6 ozf)
Factory setting for high force direction = 1.4 N / 140 gf (4.9 ozf)
Maximum setting for low force direction = 2 N / 200 gf (7.0 ozf)
Maximum setting for high force direction = 3.5 N / 350 gf (12.3 ozf)
Minimum setting for low force direction = 0.5N / 50 gf (1.7 ozf)
Minimum setting for high force direction = 0.9 N / 90 gf (3.2 ozf)

RMP60 DIAPHRAGMS
The probe mechanism is protected from coolant
and debris by two diaphragms. These provide
adequate protection under normal working
conditions.
The user should periodically check the outer
diaphragm for signs of damage. If this is evident,
replace the outer diaphragm.
The user must not remove the inner diaphragm.
If damaged, return the probe to your supplier.
OUTER DIAPHRAGM INSPECTION
1. Remove the stylus.
2. Undo the three M3 front cover screws and
remove the front cover.
3. Inspect the outer diaphragm for damage.
4. To remove the outer diaphragm, grip by the
outer edge and pull off.
INNER DIAPHRAGM INSPECTION
5. Inspect the inner diaphragm for damage.
If damaged return the probe to your supplier.
DO NOT REMOVE THE INNER DIAPHRAGM
AS THE WARRANTY WILL BE VOID.

OUTER DIAPHRAGM REPLACEMENT
6. Fit the new diaphragm over centre.
7. Locate the outer edge of the diaphragm to
8. Refit the front cover and the M3 screws.
9. Refit the stylus and re-calibrate the probe.
