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.

Yellow - Battery low and M code start/stop in progress.

Red/off - Flashing: RMI-Q has an overcurrent condition.

PROBE STATUS LED

Red - Probe triggered.

Green - Probe seated.

NOTES:

The 'PROBE STATUS' LED is always illuminated when power is present at the RMI-Q (as the RMI-Q does not incorporate a separate ‘power present’ indicator).

All LEDs 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 illuminate red. The 'LOW BATTERY/START' and 'SIGNAL' LEDs will be off.

When the RMI-Q is powered on it will enter the acquire partner mode. This is indicated by a ﬂashing green 'SIGNAL' LED (no change in outputs). After ~60 seconds it will switch to its normal mode listening for its partner.

The conditions shown by the 'LOW BATTERY/ START', 'PROBE STATUS' and 'ERROR' LEDs are the same as those present on the electrical signal outputs.

Red/off - Flashing: RMI-Q has an overcurrent condition.

RMI-Q inputs

Machine start inputs (P1, P2, P3, P4):

'Machine start' inputs are configurable as a level or pulsed signal.

Level

Pulsed

P1 machine start wires (white +ve and brown -ve). P2 machine start wires (pink +ve and brown -ve). P3 machine start wires (white/red +ve and brown -ve). P4 machine start wires (white/blue +ve and brown -ve).

10 to 30 V (2.4 mA at 24 V) When input is active, probe is switched on.

12 to 30 V (10 mA at 24 V) Probe toggles from being switched on/ off. The minimum pulse width is 10 ms.

Output voltages

Sourcing = 4.2 V min at 10 mA.

•

= 2.2 V min at 50 mA.

Sinking = 0.4 V max at 10 mA.

•

= 1.3 V max at 50 mA.

Probe status 2b (driven at power supply voltage):

Load current = 50 mA max.

•

Output voltages

Sourcing voltage drop

•

= 2.6 V max at 10 mA. = 3.5 V max at 50 mA.

Sinking voltage drop

•

= 2.0 V max at 10 mA. = 2.9 V max at 50 mA.

RMI-Q outputs

There are five outputs:

Probe status 1 (SSR).

•

Probe status 2a

•

(5 V isolated driven skip).

Probe status 2b

•

(driven at power supply voltage).

Error (SSR).

•

Low battery (SSR).

•

All outputs can be inverted by using switches SW1 and SW2 - see page 2.8 'Switches SW1 and

SW2'.

Probe status 1, Error, Low battery (SSR):

‘On’ resistance = 50 ohm max.

•

Load voltage = 40 V max.

•

The 'LOW BATTERY/START', 'PROBE STATUS', 'ERROR' and 'SIGNAL' LEDs will start flashing red when an output overload has occurred. All outputs will be switched off. If this occurs, turn off the power supply and remove the source of the problem. Turning on the power supply will reset the RMI-Q.

Load current = 100 mA max.

•

Probe status 2a (5 V isolated driven skip):

Load current = 50 mA max.

•

CAUTIONS:

Power supply voltage

Do not exceed 30 V between the black wire and the screen wire (green/yellow), or the red wire and screen wire (green/yellow), or the red and black wires (power supply), as this could result in permanent damage to the RMI-Q and/or the customer power supply.

The use of in-line fuses at the machine cabinet end is recommended to provide protection for the RMI and cable.

Screen connection

A good connection must be made to machine ground (star point).

Output stage circuit

Output stage supplies (+ve, –ve) should not be switched on and off to enable/disable them as this can cause the over current protection to switch off the output completely.

Ensure that outputs from the RMI-Q do not exceed speciﬁed current ratings.

NOTES: Machine start input P4 is not used in common start.

Only the probe start signal P1 will be pulsed and will change the probe status between on and off. The probe selection inputs P2 and P3 will be level.

Seated start on

When seated start on is selected, the RMI-Q will not drop the error line until the RMP has become seated. This provides compatibility with controllers that regard the RMP to be in error if it is started in a triggered condition.

0.5 second turn on

0.5 second turn on provides compatibility with controllers that have quicker response times, to give a reduced probing cycle time. Standard turn on time is 1 second. These turn on times apply to radio M code on only.

Remote external audible output

Any output (set to pulsed) can be utilised to operate an external remote audible indicator.

The audible indicator must comply with the output transistor specification. i.e. up to 50 mA. up to 30 V.

RMP - RMI-Q partnership

The RMP and RMI-Q must be placed into acquisition mode.

On the RMP, acquisition mode achieved using Trigger Logic™.

Partnering can take place anywhere within the operating envelope.

1. Use Trigger Logic™ to access RMP configuration mode.

2. Configure switch-on method (if applicable).

System

installation

On the RMI-Q, acquisition mode is achieved either by manually power cycling the RMI-Q, or via application of ReniKey which is a Renishaw machine macro cycle.

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 deflection (triggering) to systematically lead the user through the available choices to allow selection of the required mode options.

Current probe settings can be reviewed by simply removing the batteries for a minimum of 5 seconds, and then replacing them to activate the Trigger Logic™ review sequence.

To partner the RMP with the RMI-Q

Partnering is required during initial system set-up. Further partnering will be required if either the RMP or RMI-Q are changed.

3. Configure switch-off method (if applicable).

4. Configure enhanced trigger filter and auto reset function (if applicable).

5. Enter acquisition mode menu.

6. Power on the RMI-Q or apply one of the ReniKey commands. Please refer to the ReniKey programming manual.

7. Watch the RMI-Q P1 system status LED; after a couple of seconds the LED will repeatedly flash on and off green. This is the start of a 60 second interval in which the RMI-Q is in acquisition mode.

8. Deflect the stylus < 4 seconds to initiate the acquisition process.

9. After successful acquisition, the RMI-Q P1 system status LED will change to repeatedly flashing red and yellow (for 5 seconds) indicating that acquisition is complete and Probe 1 is full.

3.3

Any RMP that is partnered with the RMI-Q, but then used with another system, will need to be cleared first from the RMI-Q before being partnered with the new system. The RMP will also need to be partnered again should it be brought back to the RMI-Q.

Partnering will not be lost by reconfiguration of probe settings or when changing batteries.

NOTE: Partnering will be lost when multiple probe mode is selected. Multiple probe mode is a function of the RMP. See the relevant RMP installation guide (see Section 6, 'Parts list').

10. Leave RMP for 20 seconds to go into standby.

11. System is ready to use.

NOTES: To check that turn on and off settings have not been accidentally changed, insert batteries to review current probe settings.

When holding the RMP do NOT wrap a hand, or anything else, around the glass window.

The system will not function correctly if more than one partnered RMI-Q is within the transmission range of the RMP.

To partner up to four RMPs with the

RMI-Q without ReniKey

The RMI-Q has four machine start inputs (P1 - P4) that enable partnering of four radio probes (see wiring diagram on page 3.2).

The partnering procedure is dependant on the start method that has been selected. See page

2.9 for start methods.

Partnering with dedicated start (Level mode)

If the RMI-Q is powered with all start inputs held low, the RMI-Q will complete its start up procedure and partner the RMP as Probe 1.

When the RMI-Q is powered with a single machine start input held high, the RMI-Q will complete its start up procedure and partner the RMP to the probe number represented by the selected machine start input.

NOTES:

Activation of machine start input (P4) is not required when common start is selected.

To aid partnering, an on/off switch can be ﬁtted

between the machine power supply and the RMI-Q (red wire). This enables the RMI-Q to be momentarily powered off and then back on, for each of the probes being partnered, without having to power off the machine.

Partnering RMPs using ReniKey

(Recommended)

ReniKey is a Renishaw machine macro cycle. It enables up to four RMPs to be partnered with the RMI-Q without the need to power the RMI-Q off and then back on for each of the probes being partnered. Please refer to the ReniKey programming manual for instructions on how to use ReniKey with your machine's controller. Alternatively, refer to www.renishaw.com.

Removing the RMP from the RMI-Q

An RMP must be cleared from the RMI-Q when it is removed from the system. The probe number is cleared from the RMI-Q by repeating the partnering procedure whilst the corresponding machine start input is held high. The RMI-Q will then display that the probe number was cleared. Alternatively, the RMP can be cleared via application of the ReniKey machine macro cycle. Please refer to the ReniKey programming manual on how to use ReniKey with your machine's controller. Alternatively, refer to www.renishaw. com. ReniKey can also be used to clear all probe numbers at the same time. If the cleared RMP is to be used again with the RMI-Q, it must be re-partnered.

Changing RMP position

If, during partnering with all procedures, the RMI-Q acquires an RMP that is already stored under a different probe number, the RMP will be cleared from its current location and stored under the new probe number selected for acquisition.
