SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013
Description: Defines the maximum modulation depth.
Dependency: Default setting PM260: 103 %.
Refer to: p0500
Note: p1803 = 100% is the overcontrol limit for space vector modulation (for an ideal drive converter without any switching
delay).
Description: Sets the filter time constant of the DC link voltage used to calculate the modulation depth.
Description: DC link voltage used to determine the maximum possible output voltage.
Description: Displays the effective modulator mode.
Value: 1: Flat top modulation (FLB)
2: Space vector modulation (SVM)
9: Optimized pulse pattern
Description: Sets the configuration for the modulator.
