Hi,
I'm sure (not exactly sure but would expect) that there will be connections for a braking resistor on your VFD.
My lathe is a similar size to yours and I can stop a 160mm chuck from 2,400 rpm in less than a second.
I have 2 off 220 Ohm 50W chassis mount resistors wired in parallel and fastened to a smallish finned heatsink. (Equivalent to 110 Ohm at 100W I hope.)
Cheers.
Phil.
P.S. Loving your videos.
