RPM override acting in reverse

Elite Series (Masso & Redline) (Gen 1)
1

Hello all,

I am setting up an Elite Foreman with a Huanyang VFD and 220v 2.2Kw liquid cooled spindle. It has taken a while to get things working correctly so that the Masso will control the spindle, but I still have a few small issues.

The issue now is that when I manually override the spindle RPM, it acts in reverse to what I expect. That is; when I increase the % RPM manually, the spindle slows down. When I decrease the spindle % RPM the speed increases.

Can anyone explain what I have done wrong here and how to correct it? I have not run any code yet. I am still going through everything to make sure I have it all wired correctly.

Thank you,

David

I solved my own problem with some more searching over in Masso.

In the VFD the documentation I have, the PD072 and PD073 explanations are reversed. I swapped the values and it works as expected now.
