SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013
For operation with output reactors, the pulse frequency is limited to 4 kHz (see p0230).
If p1800 is changed during commissioning (p0010 > 0), then it is possible that the old value will no longer be able to
be set. The reason for this is that the dynamic limits of p1800 have been changed by a parameter that was set when
the drive was commissioned (e.g. p1082).
Description: Display and connector output for the actual converter switching frequency.
Index: [0] = Actual
[1] = Modulator minimum value
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
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: 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 = 98%). The higher the overmodulation, the greater the current 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.
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
