Probe data signals are transmitted via radio link to the RMI and on to the machine control. The RMI converts probe signals into an acceptable form for the machine control.

System performance

Operating envelope

Surfaces within the machine may increase the signal transmission range.

Coolant and swarf residue accumulating on the RMP60 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 with your hand, either the RMI cover or the probe glass window, as this will change the performance.

Operation in extremes of temperature will result in some reduction in range.

RMI position

To assist finding the optimum position of the RMI during system installation, a signal strength indication LED is available on the RMI interface.

RMI signal strength is displayed on an RMI multi-coloured LED.

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.

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.

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

Spin at 650 rev/min for 1 sec minimum (maximum 6 sec)

3. Shank switch

Note:

RMP60 will be turned on after 1 sec in all modes.

RMP60 switch-off

Modes of operation

Switch-off options are programmable

Three switching methods can be used.

1. Radio stop

Radio switch off is commanded by a M code.

(Only applies when radio turn on is selected).

A timer automatically switches the probe off after 90 min from last trigger if not turned off by M-code.

2. Timer off (time out)

(Only applies when radio on/spin on mode is selected). The RMP60 will time out (12, 33 or 134 sec) after the last probe trigger or reseat.

3. Spin stop

(Only applies when spin on mode is selected).

A timer switch automatically swiches the probe off after 90 min from last trigger off, if not spun off.

4. Shank switch

(Only applies when shank on mode is selected).

Note:

After being turned on, the RMP60 must be on for a minimum of 1 sec (7 sec for spin off) before being turned off.
