Danfoss vlt aqua Programming Guide

This parameter defines which input will be used as the source
of the first feedback signal.
Analog input X30/11 and Analog input X30/12 refer to inputs on
the optional General Purpose I/O board.
NB!
If a feedback is not used, its source must be set to
No Function [0]. Parameter 20-10
determines how the three possible feedbacks will be used by the PID Controller.
20-01 Feedback 1 Conversion
Option: Function:
[0]
*
Linear
[1] Square root This parameter allows a conversion function to be applied to
Feedback 1.
Linear [0] has no effect on the feedback.
Square root [1] is commonly used when a pressure sensor is
used to provide flow feedback (
(
flow ∝ pressure
)
).
20-03 Feedback 2 Source
Option: Function:
See
Feedback 1 Source , par. 20-00 for details.
20-04 Feedback 2 Conversion
Option: Function:
See
Feedback 1 Conversion par. 20-01 for details.
20-06 Feedback 3 Source
Option: Function:
See
Feedback 1 Source , par. 20-00 for details.
20-07 Feedback 3 Conversion
Option: Function:
See
Feedback 1 Conversion , par. 20-01 for details.
20-12 Reference/Feedback Unit
Option: Function:
[0] None
