This parameter and Pr 12.06 are used to invert the logic states of the threshold output if required.
This parameter and Pr 12.07 define the parameter which is to be controlled by the threshold parameter. Only bit parameters which are not protected
can be set up as a destination. If a non valid parameter is programmed the output is not routed anywhere.
These parameters and Pr 12.08 and Pr 12.09 define the parameters which are to be switched by the variable selector block. These can bit variables
or non bit variables but not a mixture of both. Also the output parameter programmed must be the same type as the destination parameter, if not they
will always read as zero. When programming a reference to a variable source select, if the reference is a percentage, then the variable source treats
the percentage as a whole number, e.g. 50.0% of reference = 50.0Hz.
The output of the variable select can be changed by the mode as in the following table:

Action Result
0 Select input 1 output = input1
1 Select input 2 output = input2
2 Add output = input1 + input2
3 Subtract output = input1 - input 2
4 Multiply output = (input1 x input2) / 100.0
5 Divide output = (input1 x 100.0) / input2
6 Time constant output = input1 / ((control param)s + 1)
7 Linear ramp
output = input1 via a ramp with a ramp time of (control param)
seconds from 0 to 100%
8 Modulus output = | input1 |
9 Raise to power
output = input
control param (1 – 3)
output = 0.02: output = input

/ 100
output = 0.02: output = input
3

2
control has any other value: output = input 1
