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, together with parameter 40.15 Set 1 output
scaling, a general scaling factor for the process 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, and parameter
40.15 to the nominal motor speed at 50 Hz.
In effect, the output of the PID controller = [40.15] when
deviation (setpoint - feedback) = [40.14] and [40.32] = 1.
Note: The scaling is based on the ratio between 40.14
and 40.15. For example, the values 50 and 1500 would
produce the same scaling as 1 and 30.
