At a  quick glance of the juno manual

4 address bytes + offset 00 $6E        LFO Rate 1

but it ha s a range of 0 to 149 which is greater than the 127 max for a
single Midi byte so Roland break it up into 2 half bytes or nibbles

It looks like it uses 2 sysex messages

$F0 Roland header  (Address + 00 $6E)  hi-nibble cks-1 6 $F7
$F0 Roland header  (Address + 00 $6F) lo-nibble cks-1 6 $F7

so

$F0 Roland header  (Address + 00 $6E)  val4.7  cks-1 6 $F7
$F0 Roland header  (Address + 00 $6F)  val0.3  cks-1 6 $F7

I assume that there was an editor that came with the Juno. Use that to
look at the sysex that is being sent out to get the correct address +
offset.

As you can see my French is a lot worse than your English.
