A Pico Sys +10 V analog output. I keep thinking it's PWM but it's not.

Actually at least the X200 and WJ200 have integral interal braking
resistors- but, for practical reasons of space and cooling, they're
undersized and only "remedial". They can't absorb the full current of
high-speed braking that the drive can potentially deliver.

I DID see there's "braking units" AND "braking resistors". I am unclear
on what's inside a braking unit. I am sure it has a self-resetting
breaker at least. But that is not even all that good to have- opening
of the breaker would cause the VFD to go into an overvolt error state.
You won't
From what I gather, the primary factor is the motor voltage and drive hp.
A 2.2KW motor with a 2.2KW drive on 208v is 10.6 amps. Well, the phase
currents are a different calc, and we're also talking about the main bus
cap in the VFD which is rectified off the 208v source. So these numbers

From what I'd Googled, the wattage can be much lower with drives for
spindles that just need them to stop on a low dut
I don't know who AT is or what your looking at, the braking resistor for
the 3hp GS2 is $76 all day long.

AT's quoted prices on their web page, a/o this morning, were uniformly
all $435 with a note they also needed some sort of a controller

On my GS-2 with the braking resistor I go from 1800 fwd to 1800 rev in 1

Without an external braking resistor, the deceleration is much more
limited. What happens is the back EMF charges the main bus capacitor,
and it will go into an overvolt error and simply freewheel to avoid
charging it further to a point where it will damage the cap.
