Description: Displays the stator current in the q axis after current actual value tracking.
Description: Sets the signal source for the excitation current actual value
Description: Displays the excitation current actual value that is read-in.
Dependency: Refer to: p0390
Description: Sets the minimum excitation current. This means that negative excitation currents can be avoided.
Description: Sets the gain factor for the minimum excitation current, closed-loop control. This is active if the excitation current is
below 75% of p1642.
Dependency: Refer to: p1642
