It took me awhile to determine these settings for the Fuling VFD (DZB312B005.5L2DK) to implement VFD braking and I thought I'd save someone else the time if you have a unit. Just for reference, braking is where you put an external resistor onto the VFD and it allows the VFD to back feed power into the resistor when the VFD quickly slows down the spindle. In my case, I can go from 16,000 RPM to 0 RPM in 2 seconds or less.

You need a 500w, 100 ohm resistor:

Then wire that up to the following terminals: DC+ BR- (forget what the diagram shows in the manual, as the manual doesn't apply completely to the DK version for router applications)

Go into the VFD setup and set the following:

F0.09 = 1 to 10 (number of seconds you want to reach zero RPM)
F0.19 = 0
F0.20 = 0
F0.21 = 0
F0.22 = 0
F0.23 = 0

Hope this helps someone else.
