Dependency: Refer to: p1802
Note: During operation (the pulses enabled) the configuration cannot be changed by changing-over drive data sets.
Description: Status of the actual value correction
Description: Sets the weighting factor for the leakage inductance of the L-R element of the actual value correction.
Description: Sets the damping factor for the actual value correction.
The factor multiplies the T0/Tsig ratio in the feedback branch of the LR element
Description: Displays phase correction currents as well as the drive converter phase currents
