Other Source selection (see Terms and abbreviations on page 144). -
40.09 Set 1 feedback 2
source
Selects the second source of process feedback. The second
source is used only if the setpoint function requires two
inputs.
For the selections, see parameter 40.08 Set 1 feedback 1
source.
Not selected
40.10 Set 1 feedback
function
Defines how process feedback is calculated from the two
feedback sources selected by parameters 40.08 Set 1
feedback 1 source and 40.09 Set 1 feedback 2 source.

In1-In2 Source 2 subtracted from source 1. 2
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) Square root of source 1. 8
sqrt(In1-In2) Square root of (source 1 - source 2). 9
sqrt(In1+In2) Square root of (source 1 + source 2). 10
sqrt(In1)+sqrt(In2) Square root of source 1 + square root of source 2. 11
40.11 Set 1 feedback filter
