NOTE
If Warning has been selected, the life ex-
pectancy of the drive will be reduced when
the mains failure persists.
461 Feedback conversion
(FEEDBACK 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 con-
nected signal. For example, this is used when flow
(volume) regulation is required on the basis of pres-
sure 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 con-
nection between the reference and the flow required.
Description of choice:
If Linear [0] is selected, the feedback signal and the
feedback value will be proportional. If Square root [1]
is selected, the adjustable frequency drive translates
the feedback signal to a squared feedback value.
