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 control
board (see Installation manual).
In the following examples, the analogue input signal is used as a frequency reference. The figures
show how the scaling of the analogue input signal is changed depending on the setting of this pa-
rameter.
