40.11 Set 1 feedback
filter time
Defines the filter time constant for process
feedback. 0.000 s
0.000…
30.000 s Feedback filter time. 1 = 1 s
40.14 Set 1 setpoint
scaling
Defines a general scaling factor for the external
PID control chain.
The scaling can be utilized when, for example, the
process setpoint is input in Hz, and the output of
the PID controller is used as an rpm value in
speed control. In this case, this parameter might
be set to 50.
