efd1Float1..1Exciter voltage at which exciter saturation is defined (Efd1) (> 0). Typical value = 2,6.
efd2Float1..1Exciter voltage at which exciter saturation is defined (Efd2) (> 0). Typical value = 3,45.
efdlimBoolean1..1(Efdlim). true = exciter output limiter is active false = exciter output limiter not active. Typical value = true.
efdmaxFloat1..1Maximum voltage exciter output limiter (Efdmax) (> ExcDC3A.efdmin). Typical value = 99.
efdminFloat1..1Minimum voltage exciter output limiter (Efdmin) (< ExcDC3A.efdmax). Typical value = -99.
