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%
