current limiting map
(typical example).
These parameters define the percentage of drive current limit
that will be applied at the speeds defined by the base 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.

PARAMETER RANGE DESCRIPTION
Nominal Speed 100–4000 rpm Sets the base speed that will be used in the drive limiting map and
PL_Nominal_Speed 100–4000 regen limiting map.
Delta Speed 50–1000 rpm Sets the width of the delta increment that will be used in the drive limiting
PL_Delta_Speed 50–1000 map and regen limiting map.
