Interphase Resistance In 12-Pulse Operation / R_Intph 12-Pulse; Field Inductance Reduction Factor / L_Field Red Fact; Short-Circuit Voltage Uk, Per Unit / V_Sh-Cct Uk P.u.; Bi: Setpoint Processing Reduction Signal Source / Red Sig S - Siemens SINAMICS DCM List Manual

p51596[0...n]

Interphase resistance in 12-pulse operation / R_intph 12-pulse

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.000 [ohm]
Description: Sets the resistance of an interphase transformer in 12-pulse operation.
Note: The parameter is set automatically during the "optimization run for pre-control and the current controller for the
armature converter" (p50051 = 25).
p51597[0...n]

Field inductance reduction factor / L_field 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 field inductance.
At 100% motor rated current (p50102), the field inductance is lower than it is at field current 0 by this factor.
Dependency: Refer to: p50116
Note: The parameter is set automatically during the "optimization run for pre-control and the current controller for the field
current controller" (p50051 = 24).
r51598

Short-circuit voltage Uk, per unit / V_sh-cct Uk p.u.

DC_CTRL Can be changed: -
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
- [%]
Description: Displays the per unit short-circuit voltage of the line supply.
The value is calculated from the commutation inductance (p51592) and the rated converter data (In = r50072[1], Vn =
p50078[0], fn = r50017).
p51607[0...n]

BI: Setpoint processing reduction signal source / Red sig s

DC_CTRL Can be changed: T
Data type: Unsigned32 / Binary
P-Group: -
Not for motor type: -
Min
-
Description: Sets the signal source for activating/de-activating the reduction factor for the speed setpoint.
Dependency: Refer to: p51608, r52194, r52195
Note: Dependent upon binector input (p51607):
1 signal:
The reduction factor (p51608) is de-activated (r52194 = r52195).
0 signal:
The reduction factor (p51608) is activated (r52194 = r52195 x p51608).
