in this video we will talk about what an
HMI communication fault is and how to
remedy this particular error on the 1861
and 71 Drive so first of all this
particular error is caused when the
keypad is losing its communication with
it with the drive especially when the
drive is looking at the keypad as a
means of a command or reference now the
HMI module it can be connected directly
on the drive as you can see right here
or you can use some kind of remote
mounting kit with a cable to not matter
motely on a door as an example or panel
so the first thing that you want to do
is make sure that the actual keypad is
not the issue or whether your keypad
cable is the issue so one things they
can do is you can try to remount your
keypad thread on the drive without a
cable or about watching it if that as I
fix your issue it can try another six
two one seven one keypad if you have
another one for spare or if another one
next to this one all the six one seven
or keypads
can be used on all the six one seven one
drives so there is no one keypad for one
drive here now on if for some reason
that does not fix your issue still then
you may have other issues within the
drive such as the control board or could
we get back keypad like I mentioned but
that's some things it can do right off
the bat to see if it's truly a keypad or
cable or whatever that may be so like I
said the keypad is particular fault
though normally happens at where the
drive is looking at the keypad for some
kind of command or reference and if it
doesn't see it as a keypad being there
then it will fall out so if you're not
using anything of the sort
if the keypad has been removed or if
you're not using a cable or or the
keypad in general to run the drive with
you can always make sure that you're not
controlling the drive
your keypad so you can go into your
drive menu and go into 1.6 command and
like I said if you're not using the
keypad then there should be no really
nothing programmed as keypad for example
I have the reference to attach to the
HMI that's what it's programmed as and I
physically removed to keep that on
purpose to similar default and now that
follows this HMI combo which is the SL
f3 fault on top left or your keypad so
normally to get rid of this fault let's
say your keypad was loose so you took it
out without knowing and you put it back
you have to power cycle your drive and
when it's it through so powered back up
again and you'll notice that once the
keypad is plugged back in once the drive
is able to communicate with your keypad
that particular fault has gone away but
as I mentioned before if I was to remove
the keypad physically and I put it back
on you'll notice that the call comes
right hm icon fault comes back again
because again it lost communication with
the keypad and as well the drive is
looking at the keypad for some kind of
command or reference so this is what you
can do to confirm what this fault is on
what you can do to remedy it you can
refer to our programming manual for more
information and this information is also
listed under the video here and it will
confirm what other good things would go
on as well as mentioned before
