FbEq Description
Reactive power compensation. See also sections Reactive power
control on page 35 and Reactive power compensation on page 35.
Defines a reference value for reactive power generation.
Reference unit can be selected by parameter 24.03 Q POWER
REF SEL.
1 = 1 Reference value when parameter 24.03 Q POWER REF SEL is
set to PHI.
Example: A value of 500 in parameter 24.02 Q POWER REF
equals to phi = 5°:
ϕ ( )
cos
Positive reference denotes capacitive load.
Negative reference denotes inductive load.
Values of parameter 24.02 Q POWER REF are converted to
degrees: -8500...8500
8500 equal -85°/85°, since the range is limited to -8500/8500.
1 = 1 Reference value when parameter 24.03 Q POWER REF SEL is
set to COSPHI.
Example: A value of 9000 in parameter 24.02 Q POWER REF
equals to cos (phi) = 0.90.
Positive reference denotes capacitive load.
Negative reference denotes inductive load.
