in this video I will show you how to
program an ATV 3-1 to drive to have plus
and minus speeds so this is where you
have almost like a jog dial where you
have a a plus sign or negative side and
when the plus logic is enabled it's
gonna ramp and come at the speed and
then once in I go it's gonna maintain
whatever you left to that is there's a
speed and same thing with - side of
things we'll use going to slow down all
the way down until you let go and it's
not maintained whatever speed you left
at as you were slowing it down so to set
this up though there's a few things that
we're gonna do the plus and minus speed
functionality has some prerequisites to
where you turn off a few functions to
allow you to even see the menu so let's
start by the very beginning so when your
main display you want to first of all
set your access level high enough to
allow you to see these parameters so you
want to enter on your display scroll
down to the control menu CTL and you
need to set your access level la si as
their level 2 or level 3 minimums so
let's enter on that let's make it level
3 and how old enter for a few seconds to
make this take effect
once that's flashed and escaped back out
to CTL now you need to go down to the
fun menu application function f v1 -
enter and the first thing is you define
the s a 1 - that's for summing and from
the factory if you enter on that you'll
find si to enter again you can see it's
programmed as an analog input - so we
got a disable that so set that to no
oops I know and then escape escape back
to si 1 - now we're going to disable the
preset speeds so I escape back to si 1 -
and then scroll down the p55 - go down
to P 5 4 first enter set that to no
disable that escape
go up to SPS to enter set that to know
enter and then escape and then I skip
again so those are basically disabled
now so you have no presets and no
summing nothing you've done that now
you'll find under fun menu still a menu
labeled as UPD watch before that there's
one last thing got to do let's get back
to your fun menu and go back under
control CTL and go down to F r2 and set
that to you B DT this has to be done
okay so enter on that escape back to f
r2 and scroll down to RFC Robert Frank
Charlie and you want to make that FR to
instead of FR one so then I want FR to
alright finally so they'll go now that
we've done that escape back to control
scroll down to fun scroll down to UPD -
this is your sub menu for the plus and
minus speeds and in here you have two
parameters you have a USP just on the
center first this is your Plus speed
they have a DSP for - speed so you have
to go in here and enter and as some to
whatever logic input you want let's go
ahead and assume Li 3 is your plus speed
just to give it a some kind of logic and
then escape and go down to DSP make the
Li for is there in - speed enter so now
we have DSP assigned as a life or and
USB a sign is Li 3 so you have your USB
as your - again let me sorry plus and
your DSPs your - so now we're basically
ready to go you can escape back out and
again so Li 3 right now is assigned as a
plus and a life force - you toggle your
run command you enable ally 3 and you
let go and you can see it's ramping up
to whatever you left - that same thing
with - you enable I for you let go and
it stops
very
you left it so this is how you program
the three one two with the plus and
minus speed functionality
