Radio approval

Radio equipment - Canadian warning

statements

English

Under Industry Canada regulations, this radio
transmitter may only operate using an antenna of
a type and maximum (or lesser) gain approved for
the transmitter by Industry Canada.

To reduce potential radio interference to other
users, the antenna type and its gain should be so
chosen that the equivalent isotropically radiated
power (e.i.r.p.) is not more than that necessary for
successful communication.

This device complies with Industry Canada
licence-exempt RSS standard(s). Operation is
subject to the following two conditions: (1) this
device may not cause interference, and (2) this
device must accept any interference, including
interference that may cause undesired operation
of the device.

Conformément à la réglementation d'Industrie
Canada, le présent émetteur radio peut
fonctionner avec une antenne d'un type et d'un
gain maximal (ou inférieur) approuvé pour
l'émetteur par Industrie Canada.

Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs,
il faut choisir le type d'antenne et son gain
de sorte que la puissance isotrope rayonnée
équivalente (p.i.r.e.) ne dépasse pas l'intensité
nécessaire à l'établissement d'une communication
satisfaisante.

Le présent appareil est conforme aux CNR
d'Industrie Canada applicables aux appareils
radio exempts de licence. L'exploitation est
autorisée aux deux conditions suivantes : (1)
l'appareil ne doit pas produire de brouillage,
et (2) l'utilisateur de l'appareil doit accepter
tout brouillage radioélectrique subi, même si le
brouillage est susceptible d'en compromettre le
fonctionnement.

Safety

Information to the user

In all applications involving the use of machine
tools or CMMs, eye protection is recommended.

Information to the machine supplier/

installer

It is the machine supplier's responsibility to ensure
that the user is made aware of any hazards
involved in operation, including those mentioned
in Renishaw product literature, and to ensure
that adequate guards and safety interlocks are
provided.

Under certain circumstances, the probe signal
may falsely indicate a probe seated condition. Do
not rely on probe signals to halt the movement of
the machine.

Information to the equipment installer

All Renishaw equipment is designed to comply
with the relevant EU and FCC regulatory
requirements. It is the responsibility of the
equipment installer to ensure that the following
guidelines are adhered to, in order for the product
to function in accordance with these regulations:

any interface MUST be installed in a position

•

away from any potential sources of electrical
noise, i.e. power transformers, servo drives
etc;

all ground connections should be connected

•

to the machine 'star point' (the 'star point'
is a single point return for all equipment
ground and screen cables). This is very
important and failure to adhere to this
can cause a potential difference between
grounds;

all screens must be connected as outlined in

•

the user instructions;

Before you begin

cables etc, or be near high speed data lines;

cable lengths should always be kept to a

RMI-Q basics

2.12.1

Introduction

CNC machine tools which are using Renishaw
spindle probes with radio signal transmission
for workpiece inspection, or tool setters with
radio signal transmission, require a Renishaw
radio machine interface (such as the RMI-Q)
for signal transmission. The RMI-Q, which acts
as a combined radio transceiver and machine
interface, converts signals from the RMP into
voltage-free solid state relay (SSR) and driven
outputs for transmission to the CNC machine
controller.

The RMI-Q is designed to be mounted within
the machine’s working envelope.

Application of the RMI-Q enables individual
radio turn on and subsequent operation of up to
four separate 2nd generation RMPs, permitting
numerous combinations of radio inspection
probes and/or radio tool setters to be used on the
same machine tool.

Optimum communication performance between
the RMI-Q and the RMP is achieved when the
RMI-Q is aligned towards the RMP in operation.
Other alignments are permissible with negligible
reduction in communication performance.
However, alignment of the RMI-Q away from the
RMP should be avoided as this may result in
reduced communication performance.

CAUTION RMI-Q operation of up to four

!

separate RMPs is different to 'multiple probe
mode' which is a function of the RMP that enables
individual application of multiple probes but does
not use radio turn on.

Power supply

The RMI-Q can draw its supply from the CNC
machine tool's 12 Vdc to 30 Vdc supply and
present a peak load of up to 250 mA during turn
on (typically 100 mA from 24 V).

RTS, and other 2nd generation RMPs, are easily
identified by a 'Q' marking. 1st generation RMPs,
which do not have the 'Q' marking, may also
be used with the RMI-Q. However, in machine
tool applications where more than one RMP
is required, it is recommended that only 2nd
generation RMPs are used. Should there be a
requirement to use a 1st generation RMP with the
RMI-Q, it is necessary that any additional probes
are 'Q' marked 2nd generation RMPs

Input voltage ripple

The input voltage ripple must not cause the
voltage to fall below 12 V or rise above 30 V.
