Note: If the test command is issued in operation (i.e. in operating state o0.1 or o0.2), then the turn-off operation of the
SIMOREG CCP acts on the thyristor bridge that is presently enabled. This is independent of whether the turn-off
command is issued in torque direction I or II.
Description: Sets the reduction factor for the current-dependent armature inductance.
At 100% motor rated current (p50100), the armature inductance is lower than it is at armature current 0 by this factor.
Dependency: Refer to: p50111
Note: The parameter is set automatically during the "optimization run for pre-control and the current controller for the
armature converter" (p50051 = 25).
Description: Sets the commutating inductance in the armature circuit.
Description: Sets the inductance of the interphase transformer in 12-pulse operation (two 6-pulse thyristor bridge circuits
connected in parallel).
Dependency: Refer to: p51595
Note: The parameter is set automatically during the "optimization run for pre-control and the current controller for the
armature converter" (p50051 = 25).
Description: Sets the reduction factor for the current-dependent interphase inductance.
At 100% motor rated current (p50100), the interphase inductance is lower than it is at armature current 0 by this
factor.
Dependency: Refer to: p51594
Note: The parameter is set automatically during the "optimization run for pre-control and the current controller for the
armature converter" (p50051 = 25).
