input
output
There are two operating modes for the MINIMUM SPEED function:
PROP WITH MINIMUM (proportional with minimum)
In this mode the MINIMUM SPEED function behaves like a simple clamp. The Minimum Speed Value has the valid range -100% to 100% and the
output is always greater than or equal to the Minimum Speed Value .
LINEAR
In this mode the MINIMUM SPEED function first clamps the input to zero then rescales the input such that the output goes linearly between
minimum and 100% for an input that goes from 0 to 100%.
Note the constraints:-
min >= 0
input >= 0
max = 100%
