current limiting map
(typical example).
These parameters define the percentage of drive current limit
that will be applied at the speeds defined by the nominal speed
and delta speed parameters. The resulting map allows the
controller to reduce the drive current as a function of speed.
Reducing the power requirements at certain speeds
restricts performance. This can be useful for reducing motor
heating. It can also be used to keep consistent vehicle power
with changing battery state-of-charge.
