380v Output Inverter Braking.

I don't know this VFD but generally, to implement a braking resistor there needs to be an additional switching device within the VFD that is activated when the internal DC bus exceeds a threshold. I've seen some examples of VFDs where the components haven't been fitted and other examples of the same basic product where they have. This manufacturer may be telling you that this particular model doesn't have them. There's no reason why one couldn't implemented, so it must be a choice the manufacturer made.

It's possible to obtain standalone braking modules that can be added to an existing VFD, being connected across the DC terminals that are usually accessible. That's possibly an option for you but unless you bought second hand, it could cost you rather a lot.
