I assume you wired those drives to the DB25 as they are 5v drives. From your link the drives don't appear to have an alarm output so you wont need a "drive ok" input on Acorn. Spindle OK is a input on Acorn that uses the fault signal from your VFD. There's a diagram for wiring a generic VFD to Acorn.

Yes straight into the db25, so I can just use the fault from the relay as per this post?

Those are open loop drives, so there is no alarm circuit available. Also, leave the enable disconnected.

Each VFD is different and you haven't told us what VFD you have or shared a link to the manual. We need a lot more info to be able to help you.

Didn't we go over this already in your other post? It's confusing when you start more than one topic with the same questions.

They are enabled by default. If the motor locks when you power up the drive it's enabled.
