SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description: Displays the actual converter switching frequency.
Index: [0] = Actual
[1] = Minimum value of the modulator
Note: The selected pulse frequency (p1800) may be reduced if the drive converter has an overload condition (p0290).
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, 10), the modulation depth
must be limited using p1803 (pre-assignment, p1803 = 98%). The higher the overmodulation, the greater the cur-
rent ripple and torque ripple. With p1802 = 10, the modulation depth limit is automatically reduced to 100% in the
critical output frequency range (over approx. 57 Hz).
When changing p1802[x], the values for all of the other existing indices are also changed.
