Vfd?

[J.W. Gross]

When I turn on my vfd sometimes the motor will run forward and sometimes it runs in reverse. Any idea what is wrong?
I have looked everything over and it looks correct, I have even tried it on a different motor and same result?
The drive is a kbac-24d. Thanks

Do you have a reversing switch? I'm not sure if you have the same #9480 sitch that I have on the Kbac 29. O could have a faulty switch or lose connections on the bak.

If you have no switch then check that the jumper is tight on the fwd and com terminals.

No reversing switch on mine. Just checked the jumper, it fits good. Still doing the same thing. Thanks.

I would call kb electronics tech dept. and ask for Charles. He was very helpful with jumper options with my 3hp motor that needed some tweaking. Sorry, that's all I got.

I figured I would have to call them. I was just making sure I was not over looking anything obvious. Thanks for the help.
