In1*In2 Source 1 multiplied by source 2. 3
In1/In2 Source 1 divided by source 2. 4
MIN(In1,In2) Smaller of the two sources. 5
MAX(In1,In2) Greater of the two sources. 6
AVE(In1,In2) Average of the two sources. 7

sqrt(In1-In2) Square root of (source 1 - source 2). 9
sqrt(In1+In2) Square root of (source 1 + source 2). 10

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 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, 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 3.
