PNO Parameter Descriptions
1906
Minimum Speed Value
Specifies the minimum output value.
1907 Minimum Speed Mode
There are two modes of operation:
Enumerated Value:
0 : PROP WITH MINIMUM
1 : LINEAR
Functional Description
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%
