Question about how to set up VFD for braking resistor

I've just installed an Omron/Yaskawa G5+ variable frequency drive on
my Bridgeport. I intend to control it from MACH3.
The good news is the VFD is working like a champ (manually still
haven't controlled it yet from MACH3). Maybe I misunderstood about
the noise, or maybe the load side reactor is doing its job because it
sounds just like a Bridgeport 2J
I've installed a breaking resistor. I'm trying to figure out what
braking mode and deceleration I should pick if I'm using a braking
resistor. Both manuals (Omron and Yaskawa) refer to it, but neither
explicitly says what function to select (DC injection braking
maybe?) Any help would be appreciated on this.
I've attached links to the two manuals to the Omron/Yaskawa G5
(Yaskawa is a better manual, but Omron has more on braking).

I've still got to tweak MACH3 a bit more (I mis-understood some of
the OEM codes and have to change them), but then I'm about done with
my retrofit (exactly two years and two redo's of the controls) and
have no more excuses to prevent me from turning out copious
quantities of parts (not sure what those are, but everyone says
that's what you're supposed to make with one of these things <G>)
