Setup::Application::Minimum Speed
Function availability depends on macro selected.
The minimum speed function is used to determine how the AC30V will follow a reference.
Parameter Name No.
Minimum Speed Value
1906
Specifies the minimum output value.
Minimum Speed Mode
1907
There are two modes of operation.
Functional Description
output
100
input
Min
-100
0 100%
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%
Path
