 cos phi (P) control curve
In cos phi (P) control curve mode, the reactive power generated by the inverter depends
on the active power. Grid voltage is used as a lock-in condition. When setting this curve,
crossing cos phi level one must be defined using two different points for the same point.
For example, input level 2 = 0,5; output level 2 = 1,0 and input level 3 = 0,5; output
level 3 = -1,0.

 cos phi (U) control curve
In cos phi (U) control curve mode, the reactive power generated by the inverter depends
on the grid voltage, as described in the example Q(U) control curve. The power reference
type is set in parameter124.06 Q power ref type = Q(x) regulation curve and
parameter124.30 Q(x) curve = CosPhi(U).
