Well certainly there's no brake resistor action going on there. You can check the resistor is still intact with your DVM. Obvs no need to actually replace it to check that - but with no voltage, it's rather academic to begin with.

The other option is as marky68 says - some parameter somewhere that isn't right, preventing it from working. A VFD without a braking resistor is pretty useless TBH.

Have you definitely selected braking resistor rather than DC braking?
