Signal smoothing
When required, you can smooth the signal, which you read-in via an analog input, using
parameter p0753.
For more information, see the parameter list and in the function block diagrams 9566 ff of the

To enter a supplementary setpoint via analog input AI 0, you
must interconnect AI 0 with the signal source for the supple-
mentary setpoint:
Set p1075 = 755[0].
Skip frequency band of the analog input AI 0 (factory setting: 0)
Skip frequency band of the analog input AI 1 (factory setting: 0)
Interferences in the cable can corrupt
small signals of a few millivolts. To be
able to enter a setpoint of exactly 0 V via
an analog input, you must specify a skip
frequency band.
