Braking
The P34 - [Stop Mode Select] 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 This function has been replaced by a five point V/Hz curve.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.
