Parameters 271
PQ curve The PQ curve is used for flow calculation.
You can configure pressure sensor settings with parameter
group 81 Sensor settings.
The figure below shows the PQ performance curve of the
pump for the flow calculation function.

80.14 Flow feedback
multiplier
Defines the multiplier (k) used with the flow calculation The
output value of 80.13 Flow feedback function is multiplied by
this value.
1.00
-200000.00…
200000.00
Multiplier. 1 = 1
80.15 Maximum flow Defines the nominal maximum flow of the system. This value
is used to calculate the actual flow percentage value so that
the value 100% for 80.02 corresponds to the value of this
parameter.
1000.00
-200000.00…
200000.00
Sets the limit for maximum flow protection. 1 = 1
80.16 Minimum flow Defines the nominal minimum flow of the system. 1.00
-200000.00...
200000.00 m
