SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Sets the modulator mode.
Value: 0: Automatic changeover SVM/FLB
2: Space vector modulation (SVM)
9: Edge modulation
19: Optimized pulse pattern
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). This does not apply to power units PM260.
p1802 = 10 can only be set for power units PM230 and PM240 and for r0204.15 = 0.
Refer to: p0500
Caution: When modulation modes are enabled that could lead to overmodulation (p1802 = 0, 2), the modulation depth must
be limited using p1803 (default p1803 < 100 %). The higher the overmodulation, the greater the current ripple and
torque ripple.
When changing p1802[x], the values for all of the other existing indices are also changed.
Note: The setting p1802 = 19 is only released for chassis power units and SIMOTICS FD motors.
Description: Defines the maximum modulation depth.
Dependency: Refer to: p0500
Note: p1803 = 100% is the overcontrol limit for space vector modulation (for an ideal drive converter without any switching
delay).
