-t/T
O = I × (1 - e
I = filter input (step)
O = filter output
t = time
T = filter time constant
Note: The signal is also filtered due to the signal interface
hardware (approximately 0.25 ms time constant). This cannot
be changed by any parameter.
Filter time constant.
Defines the minimum site value for analog input AI1.
Set the value actually sent to the drive when the analog signal
from plant is wound to its minimum setting.
