[S Curve Accel 1]
Amount of time (approximately half at the start and half at the end) applied to the
S-curve during Accel 1 changes. When Par 19 [S Curve Time] is changed this
parameter is automatically set to the same value. For asymmetrical S-curve ramps,
set this parameter after [S Curve Time] is changed.

[Droop Percent]
Droop function gain is a percentage of the ratio between Par 45 [Max Ref Speed]
and the difference of Par 698 [Load Comp] – Par 41 [Current Reg In]. Therefore,
when the difference between Par 698 [Load Comp] and Par 41 [Current Reg In] =
100% and Par 696 [Droop Percent] = 100%, the speed reference correction signal
is equal to Par 45 [Max Ref Speed].
