MG.60.B1.02 - VLT is a registered Danfoss trade mark
Feedback handling, cont.
416 Feedback conversion (FFEEDBACK CONV.)
Value:
★Linear (LINEAR) [0]
Square root (SQUARE ROOT) [1]
Function:
In this parameter, a function is selected which
converts a connected feedback signal from the
process to a feedback value that equals the square
root of the connected signal.
This is used, e.g. where regulation of a flow (volume)
is required on the basis of pressure as feedback
signal (flow = constant x √pressure). This conversion
makes it possible to set the reference in such a way
that there is a linear connection between the
reference and the flow required. See drawing in next
column.
Feedback conversion should not be used if 2-zone
regulation in parameter 417 Feedback function has
been selected.
Description:
If Linear [0] is selected, the feedback signal and the
feedback value will be proportional.
If Square root [1] is selected, the VLT frequency
converter translates the feedback signal to a squared
feedback value.
