SINAMICS G120 / Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
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
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 is not valid for the power units PM260. p1802 = 10 can
only be set for the PM230 and PM240 power units.
Refer to: p0230, p0500
Note: When modulation modes are enabled that could lead to overmodulation (p1802 = 0, 2,10), 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.
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).
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).
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).
