Braking
The P34- [Stop ModeSelect] setting 3, “DC Injection Braking (w/Auto
Shutoff)” function uses a new parameter for current limit during
braking. This allows maximum braking performance.

Braking Parameters
Five Point V/Hz Curve
V/Hz curves are programmed in the standard drive with P38 - [Boost
Select]. This function has been replaced by a five point V/Hz curve.
The curve can be adjusted using the parameters described in Table E.
The ramp will start at the programmed start frequency, but will ramp
down to zero when stopping or reversing (if the start frequency is
non-zero). The voltage will follow a straight line drawn from the start
point to zero frequency and zero voltage.
