Enhanced Trigger Filter - Renishaw RMP40 Installation Manual

RMP40 switch-on method
Switch-on options are
configurable
Radio on
Radio switch on is commanded by
machine input.
Spin on
Spin at 500 rev/min for 1 second
minimum (6 seconds maximum).
NOTE: After being switched on, the RMP40 must
be on for 1 second minimum. When using spin on
/ spin off, ensure that the probe is stationary for
1 second minimum after it has stopped spinning
before using spin on.

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 10 ms delay
is introduced to the probe's output.
The RMP40 is factory-set to trigger filter off.
NOTE: It may be necessary to reduce the probe
approach speed to allow for the increased stylus
overtravel during the extended time delay.
RMP40 switch-off method
Switch-off options are
configurable
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 1 second
minimum (6 seconds maximum).
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.
Switch-on time
1 second maximum
Note: This assumes
a good radio
communication link.
In a poor RF
environment this may
rise to a maximum of
3 seconds.
2 seconds maximum.
Note: The 2 seconds
starts from the
moment the spindle
reaches 500 rev/min.
