Explanations:
Ra: Resistance of the armature circuit of the motor.
La: Inductance of the armature circuit of the motor.
Rs: Resistance of the interface transformer/smoothing reactor in 12-pulse mode.
Ls: Inductance of the interface transformer/smoothing reactor in 12-pulse mode.
Lk: Commutation inductance.
<1> Reduction factors p51591, p51595:
The percentage value to which the inductance drops at a current dictated by p50100 (motor rated armature current).
(For non-current-dependent inductances, this value is 100 %.)
