Now if I type m3 in MRI the drive faults
But if I go to the modbus monitor and read the holding registers i
The fault clears and I get this

Hi,
from the first pic you uploaded it doesn't look like you've done anything I've suggested.

The port number you must discover for yourself by using Windows Device Manager and finding the port your 485 adapter
is plugged into.

Have you programmed your drive P 9.02 and P 3.00 yet?

If you apply the cfg's the starting address is in each one.

Yes parmeter 3.0 set to #3
Parameter 9.2 set to 3

Changed port setting in device manager and drive to 8,n,2

Hi,
starting to make some progress. Can you post a screen pic of the Modbus setup page.

I think that timeout your experiencing is when the Modbus plugin sends a message it expects an acknowledgement,
if it doesn't get one within  the specified time it faults out.

If you change the comm protocol provided you reprogram P 9.02 to the appropriate setting so the drive knows how
Modbus intends signalling you should be fine. If you are of the opinion that the previuos setting of 8,1,o is better then
by all means change it. Read the manual to find the appropriate number for parameter 9.02.

So we made a bunch of progress
I read another post saying we don't need the 4 in the address so instead of 42330 is just 233
Also I set up the addresses differently from another post cfg1 is cw/ccwand run  at 2331 using 2 regesters
And cfg 2 is speed at 2330 using 1 register

So now when I do m3,m4and m5 my display on vid changes correctly stop,run,fed and rev
but it say it has no speed reference

And when I read the regester 2331 i see the bits changing

We did it the drive starts and stops with the m3,m4 and m 5 commands in Mdi
frequency /speed is not correct but it's working
The frequency scaling is for another day
Thanks for all you help

Hi,
kool, I came across something similar with my Delta VFD where I had to drop the leading digit.
If memory serves I could have used Hex representation without change.

See if you can't  find the frequency resolution. Another thread,another VFD the frequency had a resolution
of 0.01HZ, so 400Hz actual required a numeric input of 40000.
