in this video we'll talk
the relays for the atv-3 20 drive and
when I say relays I'm talking about
status relays not logic but relays in
general they're labeled here on the 320
drive as r1 r2 as you can see here on
the top of the wiring block here now a
couple of things before we get started
with the programming r1 can be a
normally closed or a normally open relay
and basically for a normally open you
have criminals r1a and r1c as you can
see right here that's normally open and
you also have our 1b and our 1c for
normally closed
so is it can tell our one Cu is always a
neutral side as a matter of using our 1a
or our 1b whether you want to normally
open or normally closed respectively
there and of course you also have our 2
a and R 2 C so this drive has the option
of giving you two normally open relays
and one normally closed with the r1 be
necessary as a standard option so to
program these drives you first of all
want to go into the configuration for
also from your main menu you want to
enter you want to scroll down into the
conf menu enter you want to scroll down
into the full menu enter and then you
want to find scroll down and you will
find inputs outputs IO enter on backs
the next settings scrolling down here
you want to find r1 and r2 and they'll
be labeled as with a dash next to it
which means that you have a submenu here
so our one dash is one menu next one
down is r2 - so let's go out on an r1 r1
- as an example here and the other
parameter R 1 so R 1 is the actual
parameter at which point your program in
the relay so when you enter 1 r1 the
first thing you see is FLT for false
that's the one single default setting on
this to r1 relay
but you can choose to assign it to one
status you know some kind of threshold
it's attained current special tained
there is dozens of different assignments
you can choose to assign those relays to
of course the most common ones are run
status or false status as this program
from a default point of view your
drivers program as a fault or one is a
fault relay from the factory just so you
know so you can choose to assign this to
whatever you want depending on what you
want to assign them to and depending on
what you want your relays to be in terms
of a normally open or normally closed
that's our one so once that's set of
course of course do you want to if you
want to change this you want to press
ENTER on the dial to save a setting but
let's go ahead an esky body here and
it's going on r2 by the way this is just
going to tell you that you can assign
your delays and stuff like that for the
same submenu here but as I said skip
back to r1 - as mentioned before r2 is
your next submenu and same as last time
you press on and on r2 and from the
factory it's not assigned so you can
scroll down to make it let's say run
status or whatever you would like
as mentioned so the our one has exact
same assignments as our excuse me r2 is
exact same as x is our one with through
the few additional assignments and
explained in the book and faq as well so
this is basically how you program a the
relays of a320 drive so let's say as an
example that you want to close the r1
relay at the event of a fault and you
also want to close the are truly lay in
the event of a run status of your motor
so what you want to do then for the r1
for fault you want to hook up to r1 b +
r1 c so that when your fault you will
close the contact the fault is kind of
backwards or seems kind of backwards but
keep in mind that r1 b
our 1c will close in a fault and our 1a
and r1c will open in a fault so keep
that in mind for the run status assuming
our truce program is a run it will go
ahead and close so our to a and our to
Susan Orlean open and it was gonna close
won't even run status but again the
fault is kind of scenes backwards that's
why keep it in mind with a run status
it's just gonna close if it's a normally
open it's an a closeness running so this
is basically how are they realized in
program the relays of the drive keep in
mind that there is some useful wiring
diagrams in the back of this door here
it should tell you some information
about how to wire a few things and this
will conclude the video on how to wire
and program the relays of an ATV 320
Drive
