<2> Frozen if the deviation in the excitation current is > p1599. With p1599 = 100 %, the function is deactivated.
<3> If <5> is applicable, the P controller becomes the PI controller (p1592). The whole output is limited. In this case, the integral-action
component is maintained. After switching back to the exciting current flux controller, the integral-action component is reduced again.
