SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013
Description: Displays the maximum output voltage.
Dependency: The maximum output voltage depends on the actual DC link voltage (r0070) and the maximum modulation depth
(p1803).
Note: As the (driven) motor load increases, the maximum output voltage drops as a result of the reduction in DC link volt-
age.
Description: Displays the actual output voltage of the power unit.
Dependency: Refer to: r0025
Note: The output voltage is available smoothed (r0025) and unsmoothed (r0072).
Description: Displays the maximum modulation depth.
Dependency: Refer to: p1803
Description: Displays the actual modulation depth.
Dependency: Refer to: r0028
Note: For space vector modulation, 100% corresponds to the maximum output voltage without overcontrol.
Values above 100 % indicate an overcontrol condition - values below 100% have no overcontrol.
The phase voltage (phase-to-phase, rms) is calculated as follows:(r0074 x r0070) / (sqrt(2) x 100 %).
The modulation depth is available smoothed (r0028) and unsmoothed (r0074).
