I would definitely use an interposing relay.

You need to. Or any other kind of 'switch'.
You can't directly connect a breakout board / controller output to vfd FWD / DCOM.
It simply does not work (or will break them) .
Put a single wire link between fwd an dcom and fwd will come on. Break that link and it will go off.
Use the relay to control the make or break link.

It's been done on another forum a while back.
Directly connected it and broke the axbb-e. Had to replace it.
May have done it wrong in first place.
Relay is the way to go.
24v coil spst.
24v module type.
24v ssr.
Think of vfd like sticking a jumper between for and dcom.
In = on, removed = off. Simples.
