SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description:
Sets the modulator mode.
Value:
0:
Automatic changeover SVM/FLB
2:
Space vector modulation (SVM)
3:
SVM without overcontrol
4:
SVM/FLB without overcontrol
10:
SVM/FLB with modulation depth reduction
Dependency:
If a sine-wave filter is parameterized as output filter (p0230 = 3, 4), then only space vector modulation without over-
control can be selected as modulation type (p1802 = 3).
Refer to: p0230
Note:
When modulation modes are enabled that could lead to overmodulation (p1802 = 0, 2), the modulation depth must
be limited using p1803 (pre-assignment, p1803 = 98%). The higher the overmodulation, the greater the current rip-
ple and torque ripple.
When changing p1802[x], the values for all of the other existing indices are also changed.

Description:
Defines the maximum modulation depth.
Note:
p1803 = 100% is the overcontrol limit for space vector modulation (for an ideal drive converter without any switching
delay).
