FILTER AI1
Filter time constant for analogue input AI1. As the analogue input value 
changes, 63 % of the change takes place within the time specified by this 
parameter. 

Note! Even if you select 0 s for the filter time constant, the signal is still filtered 
with a time constant of 0.1 ms due to the signal interface hardware. This cannot 
be changed by any parameters.
