Significance
The closed-loop thyristor current control can be used with normalized
(standard) and absolute values.
For the example for the settings of the system parameters, the following
are used as basis: A 6QG3230-2AB SITOR set (3-ph./400[V], AC 30[A] +
field) and a DC motor with the rated data:
Armature:
Field:
and the phase-to-phase line supply voltage: UL=400 V.
Parameter
