SOLVED
When I engage regen it stutters, as if it's only working on two phases or halls are going crazy.
I observe my CA speed reading also goes haywire. into the 30's to 50's if I'm only doing 20 and enable regen. Speed reading is fine during all other points of operation.
Everything else works well.
Same (solved) problem from past controller: I had an EB2xx 24FET that gave this same problem. One day it blew and I went to fix it. ... I replacement the usual mosfets and happend to observe a resistor around gate drivers that was not reading same value as same resistor on other two phases. I decided to replace that resistor. ...the controller's regen then behaved correctly but I can't quite say this resistor was the cause of regen stutter for that controller.
So going back to this new 18FET, I now decided to look at the resistors around gate driver area thinking there's a resistor badly out of tolerance but all seem fine.
My investigation ends here.
Why does this EB218 18FET stutter upon regen?
(running cromotor in 20" wheel).
