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”).

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

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.
RMP400 switch-on method
Draft 5 16/04/18
Switch-on options are configurable
RMP400 switch-off method
Switch-off options are configurable
Probe ready time
Radio on
Radio switch on is commanded by machine input.
Spin on
Spin at 500 rev/min for one second minimum.
Radio off
Radio switch off is commanded by machine input. A timer automatically switches the probe off 90 minutes after the last trigger if it is not turned off by machine input.
Timer off (timeout)
Timeout will occur 12, 33 or 134 seconds (user configurable) after the last probe trigger or reseat.
Spin off
Spin at 500 rev/min for one second minimum. A timer automatically switches the probe off 90 minutes after the last trigger if it is not spun.
Timer off (timeout)
Timeout will occur 12, 33 or 134 seconds (user configurable) after the last probe trigger or reseat.
1.7 seconds maximum.
RMP400 basics
2.3
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.

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.
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.
