When this parameter is given a value greater than 0 the function that filters out disturbances
from the incoming analogue signal is activated.
NOTE: Long filtering time makes the regulation response slower!

The signal range for the analogue signal can be selected as:
Type of the analogue input signal (current or voltage) is selected by the dip switches on the con-
trol board (see Installation manual).
In the following examples, the analogue input signal is used as a frequency reference. The fig-
ures show how the scaling of the analogue input signal is changed depending on the setting of
this parameter.
