Positioning The Rmp400 And Rmi Or Rmi-Q; Performance Envelope - Renishaw RMP400 Installation Manual

Positioning the RMP400 and RMI or
RMI-Q
The probe system should be positioned so that
the optimum range can be achieved over the full
travel of the machine's axes. Always face the front
cover of the RMI or RMI-Q in the general direction
of the machining area and the tool magazine,
3.2
ensuring both are within the performance
envelope shown below. To assist in finding the
optimum position of the RMI or RMI-Q, the signal
quality is displayed on an RMI or RMI-Q signal
LED.

NOTE: Installing the RMP400 and RMI or RMI-Q
with the RMP400 in radio-on configuration
The RMP400 has a built-in hibernation mode
(battery-saving mode) that saves battery life
when the RMI or RMI-Q is unpowered in radio-on
(radio-off or timer-off) configurations. The RMP400
goes into hibernation mode 30 seconds after
the RMI or RMI-Q is unpowered (or the RMP400
is out of range). When in hibernation mode, the
RMP400 checks for a powered RMI or RMI-Q
every 30 seconds. If found, the RMP400 goes
from hibernation mode to standby mode, ready for
radio-on.

Performance envelope

The RMP400 and RMI or RMI-Q must be within
each other's performance envelope, as shown
below. The performance envelope shows line-of-
sight performance, however, this is not necessary
for the RMP400 radio transmission as it will
operate with any reflected radio path provided
that the reflected path length does not exceed the
15 m (49.2 ft) operating range.
