SINAMICS S List Manual (LH1), 07/2007
Description: Sets the modulator mode.
Values: 0: Automatic changeover SVM/FLB
1: Flat top modulation (FLB)
2: Space vector modulation (SVM)
3: SVM without overmodulation
4: SVM/FLB without overcontrol
5: SVM with pulse frequency reduction
6: SVM/FLB with pulse frequency reduction
7: No edge modulation up to 100 Hz
8: No edge modulation up to 60 Hz
9: Edge modulation
Dependency: If a sinusoidal filter is parameterized as output filter (p0230 = 3, 4), or if the power unit firmware is not able to calcu-
late edge modulation (r0192 bit0 = 0), then only space vector modulation without overcontrol can be set as modula-
tion type (p1802 = 3).
Refer to: r0192, p0230, p7003
Notice: If the edge modulation is enabled (p1802 > 6), then the current actual value correction should be activated (p1840.0
= 0), if the Motor Module is connected to a controlled (regulated) DC link (Active Infeed).
Note: When modulation modes are enabled that could lead to overmodulation (p1802 = 0, 1, 2, 5, 6), the modulation
depth must be limited using p1803 (pre-assignment, p1803 = 98%). 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.
p1802 = 7, 8 should be used if the drive is operated below 100 Hz or 60 Hz, and it is necessary to avoid changing
over to edge modulation. Above these output frequencies, the modulation depth remains limited so that there the
full output voltage of the edge modulation is not reached.
Description: Defines the maximum modulation depth.
Note: p1803 = 100 % is the overcontrol limit for space vector modulation (or an ideal drive converter without any switching
delay).
If an optimized pulse pattern is enabled (edge modulation), then the modulation depth is limited to below the output
frequency of 28 Hz as there is no optimized pulse pattern in this range.
