3.1 RLE set-up – dip switches
If the RLI20 is being used with an RLE system, care should be
taken setting the RLE configuration switches correctly.

Note: The RLE axis direction reversal switches 6 and 7 only
affect the direction of the digital quadrature from the RLE and
not the analogue quadrature.
Description
To give analogue quadrature
output
So the RLE does not tri-state the
quadrature on error
Unless the fine digital quadrature
output from the RLE is also
required (in addition to the RLI20
laser position output).
So that the RLE does not latch
errors. The RLI20 will latch any
errors flagged
Note: The RLE will flag an error when the measurement
velocity reaches a level at which the required output rate of the
digital quadrature exceeds the digital bandwidth limit of the RLE.
The digital bandwidth limit depends on the digital quadrature
resolution and maximum output bandwidth selected with the
RLE DIP switches. The digital quadrature resolution and the
digital output bandwidth should be selected so that the RLE
measurement velocity limit is sufficient for the application. It
is therefore recommended that fine quadrature is disabled by
setting RLE switch number 12 UP.
For further information on the RLE front panel switches refer to
the RLE manual (M-5225-0568).
