RMP600 basics
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.
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 RMP600 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.
When using a 200 mm long stylus or heavy stylus configurations, a 1 second dwell is required. This will
necessitate edits to the machine probing programme.
When in
“auto-reset mode”
, the probe will not trigger when moved below a speed of 3 mm/min.
NOTE:
Speeds below 3 mm/min commonly occur when manually moving the probe using the
handwheel with a very fine feedrate.
Multiple probe mode
The RMP600 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.
Up to four RMP600s can be used with a single RMI-Q in
“radio on / radio off mode”
. For further
details of this functionality, refer to the
RMI-Q radio machine interface
installation guide (Renishaw part
no. H-5687-8504).
NOTES:
“Multiple probe mode”
is a function of the RMP600. As such, the option will not appear when the
“radio on mode”
has been selected.
RMP600 probes which are set to
“multiple probe on mode”
can coexist alongside any number of
RMP600 probes set to
“multiple probe off mode”
.
