SINAMICS DCM
594 List Manual (LH8), 02/2015, 6RX1800-0ED76
Description: Load connection:
Display and connector output for the supplementary current setpoint.
Note: This is used to increase the dynamic response of the voltage control regarding disturbing variable changes when
using the SINAMICS DCM as I/R unit or supplying a DC busbar.
A supplementary current setpoint is input, which is calculated according to the following formula:
I_(set,suppl)=I_d-C*(dU_d)/dt
100 % corresponds to p50072[1]
Description: Display and connector output for the line voltage U-V in the armature circuit.
Description: Display and connector output for the line voltage V-W in the armature circuit.
Description: Display and connector output for the line voltage W-U in the armature circuit.
Description: Display and connector output for the line voltage in the field circuit.
