Armature Inductance Reduction Factor / L_Armat Red Fact; Armature Commutating Inductance / Arm Lk; Interphase Inductance In 12-Pulse Operation; Interphase Inductance Reduction Factor / L_Intph Red Fact - Siemens SINAMICS DCM List Manual

2 Parameters
2.2 List of parameters
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.

Armature inductance reduction factor / L_armat red fact

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
10 [%]
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).

Armature commutating inductance / Arm Lk

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.0 [mH]
Description: Sets the commutating inductance in the armature circuit.
p51594[0...n] Interphase inductance in 12-pulse operation / L_intph 12-pulse
DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.0 [mH]
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).
p51595[0...n]

Interphase inductance reduction factor / L_intph red fact

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
10 [%]
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).
