Reactive power control with CosPhi displacement factor

The fCosPhiSet process data input specifies the setpoint for the displacement factor in ByCosPhi operation mode. This control is configured via the ReactiveByCosPhi parameter group (see ReactiveByCosPhi).

The sign of the CosPhi setpoint must be specified according to the generator reference arrow system (see Reference arrow system):

The ReactiveTargetDefault parameter defines the default value for CosPhi (see ReactivePower). This is also used if no valid setpoint is available via the communication interface when the controller is started or if the connection to the grid operator is interrupted.
