SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Note: The maximum possible pulse frequency is also determined by the power unit being used.
When the pulse frequency is increased, depending on the particular power unit, the maximum output current can be
reduced (derating, refer to r0067).
If a sine-wave filter is parameterized as output filter (p0230 = 3), then the pulse frequency cannot be set below the
minimum value required for the filter.
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: Sets the drive converter switching frequency.
This parameter is pre-set to twice the rated converter value when the drive is first commissioned.
Dependency: Refer to: p0230

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
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.
