Modes of operation
Modes of operation
The RMP60 probe can be in one of three modes:
1. Stand-by mode - The RMP60 is waiting for
a switch-on signal .
2. Operating mode - Activated by one of the
switch on methods described on this page.
In this mode and the RMP60 is now ready
for use.
RMP60 switch-on
RMP60 power on/off
Switch-on options are configurable
- see page 13.
Three switching methods can be used.
1. Radio start
Radio switch-on is commanded by
M code.
2. Spin start
3. Configuration mode - The trigger-logic
configuration method allows a number of
RMP60 set-up options to be configured by
triggering the RMP60, including the switch-off
options described on page 25.
Spin at 650 rev/min for 1 sec minimum
(maximum 6 sec)

System setup/establishing RMP60-RMI partnership.
Setup is done by using the RMP60 trigger logic
and powering on the RMI at a particular time
during the process.
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 insertion
followed by further RMP60 triggering.
This leads the user through a series of choices
allowing selection of the required options.
Reviewing of choices made can be made by
battery insertion alone. See pages 12 and 13 for
full details of reviewing probe settings and
configuration using trigger logic.
1.
Use trigger logic to set RMP60 turn on/ off
modes as desired.
2.
Use trigger logic to access RMP60
acquisition mode (light blue flashes, 2 short
1 long).
3.
Warning
When holding the RMP60 do NOT wrap
a hand, or anything else, around the
glass window.
Power on the RMI.
4. Wait until RMI signal led flashes green.
5.
Trigger the probe (min 0.1 sec max 2 sec)
RMP60 will flash 2 x turquoise short,
followed by 1 red long and repeat until
acquistion occurs.
6.
RMI pattern will change to red & yellow
flashing when it acquires the RMP.
7.
Allow ~10 seconds for both RMP60 and
RMI to timeout all RMP60 LEDs off and RMI
signal LED off. The system is then ready for
use.

RMP60-RMI partnership
Note.
When the RMP60 and RMI become partners the
RMI records the RMP60 serial number. It is not
possible for an RMI to be partners with more
than one RMP60.
It is possible for an RMP60 to be partners with
more than one RMI, but the system will not
work correctly if more than one partner RMI is
powered on at any one time.
RMP60 batteries
17
RMP60 batteries
Replacing batteries
Only use specified batteries.
Clean and dry RMP60 with a cloth or paper towel
before removing 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 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.

Low battery indicators
The low battery warning will be signalled by the
alternate blue flashing of probe status LED
when the end of the usable battery life is
approaching. Simultaneously, the low battery
LED on the RMI will be lit.
Dead battery indicators
When the battery voltage drops below the
threshold where performance can be
guaranteed, the RMP60 probe status LED
will change to constant red.
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), NiCad or NiMh.
For applications requiring maximum battery
life, a high capacity lithium thionyl chloride type is
essential.

RMP60/shank mounting
If the RMP60 does not have a shank switch,
please proceed from note 3.
1. Remove plug from rear of RMP60 using pliars.
2. Place bobbin into shank.
3. Fully slacken four screws A.
4. Grease two screws B, and fit into shank.
5. Fit RMP60 onto the shank, and visually
position centrally.
6. Tighten screws B to 6-8 Nm (4.4- 5.9 lb.ft)
(Partially tighten screws B to 2 - 3 Nm
(1.47 - 2.2 lbf.ft), if RMP60 is to be on-centre
adjusted).
7. The RMP60 assembly is ready for use.
Note :
Bobbin
1 . DURING ADJUSTMENT CARE SHOULD
BE TAKEN NOT TO ROTATE THE RMP60
RELATIVE TO THE SHANK.
2. IF A RMP60/SHANK UNIT IS ACCIDENTALLY
DROPPED, IT SHOULD BE CHECKED FOR
ON-CENTRE POSITION.
3. DO NOT HIT OR TAP THE PROBE TO
ACHIEVE ON-CENTRE ADJUSTMENT.

8. Each of the four screws A will move the
probe relative to the shank, in the X or Y
direction as pressure is applied.
Tighten individually, backing off after
each movement.
9. 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).
4 mm AF
2,5 mm AF
10. 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.
11. 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 adjustment
Stylus trigger force adjustment
Spring force within the probe causes the
stylus to sit in one unique position, and return to
this position following each stylus deflection.
Stylus trigger force is set by Renishaw. The user
should only adjust trigger force in special
circumstances e.g. excessive machine vibration
or insufficient force to support the stylus
weight.
To adjust trigger force, and 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 overtightening the adjusting
screw.

Probe moves
Probe moves
Probe trigger
A probe trigger signal is generated when the
probe’s stylus is driven against a surface.
The machine control records the contact
position and instructs machine motion to stop.
To ensure a trigger signal, drive the probe
against the workpiece to a target beyond the
expected surface, but within the limits of stylus
overtravel. After the probe stylus touches the
surface, reverse clear of the surface.
With a double touch sequence the first move finds
the surface quickly. Then the probe is backed off
to a position clear of the surface, before making
the second touch at a slower feed rate, thereby
recording the surface position at a higher
resolution.
Probe measuring speed
The probe system transmission delay time is
small and constant. It does not normally limit the
probing speed, because it is cancelled out during
calibration of the probe on the machine tool.
Single and double touch probing
If the probe operating sequence is based on a
single touch, then the probe is returned to its
start point following a measuring move.
On some types of controller, it is desirable to
use a two touch method, as poor accuracy and
repeatability can result at higher feed rates.
High probing speeds are desirable, however if
used, a probing velocity must be chosen which
allows the machine to stop within the limits of
stylus overtravel, and measuring capability of
the machine.
Probe moves
25
It is important that calibration cycles are run at
the measuring cycle feed rate to cancel out
system errors.
Calibration measurements should be made in
every measuring direction to provide complete
calibration data for the measuring cycles.
Probe interface signals
X/Y X/Y
1. Error signal delay
Probing cycles are available from Renishaw
Calibrating a system
Calibration should be done in the following
circumstances:
1. Before the system is used
2. When a new stylus is used.
3. To allow for machine thermal growth.
4. Poor relocation repeatability of the probe
holder with machine spindle.
A delay of 28 ms maximum for the RMI, will
elapse between an error occurring and the
output indicating error.
2. Probe signal delay
There is a nominal delay of 10 ms with a
variation of ±10 µs for an interface, from the time
the probe actually operates, to the RMI interface
outputting a probe change of state.

Software requirements
Software requirements
Probing cycles and features are machine
software dependant. Good software will allow the
following functions :
Verify your software
Does your software have suitable calibration
routines which compensate for stylus on-centre
errors? If not, you must set the probe stylus
on-centre mechanically.
●
Simple to use cycles
●
Update a tool offset
●
If an out of tolerance is found, either
generate an alarm stop, or set a flag for
corrective action
Note: Machining centre applications :
When using probe styli which are not on spindle
centre, spindle orientation repeatability is
important to avoid probe measurement errors.

No Error.
4. Signal
Green
Full signal strength.
Yellow
Medium signal strength.
Red:
Low signal strength, radio
link may fail.

No signal detected.
Green/off
Flashing: RMI is acquisition
mode, and can acquire a
partner RMP.
Red/yellow
37
Flashing: RMI has (just)
acquired a new partner RMP.
1. The probe status LED will always be
illuminated when power is present, there
is no power present LED/light.
2. All the indicators report the status of the
partner RMP. If there is no partner in range,
or the partner is off then the probe status
and error LEDs will be red and the other
LEDs will be off.
3. When the RMI is powered it will enter the
acquire partner mode which will be indicated
by the flashing. After a short time (~12 secs)
it will switch to its normal (passive) mode
listening for its partner.
4. The conditions shown by the low battery,
probe status and error LEDs are the same
as those present on the electrical signal
outputs.
