SINAMICS G130/G150
464 List Manual (LH2), 07/2016, A5E03263479A
Description: Sets the amplitude of the statistical wobbulation signal.
This signal is used to vary the pulse frequency to create a more pleasant sound.
Note: p1811 > 0 is possible, if the following applies:
- configuration: p1810.2 = 1 (wobbulation activated)
- pulse frequency: p1800 <= 1000 / p115[0]
- output filter, filter type: p0230 < 3 (no sine-wave filter)
Description: Sets the signal source to activate/deactivate offset calibration for output current measurement.
Caution: The absence of offset calibration can have a negative effect on control properties. Offset calibration must be
performed before switching on the power unit for the first time after POWER ON.
Note: Offset calibration is only performed with pulses suppressed and can take up to one second.
Description: Sets the filter dead bandwidth for the DC link voltage signal to switch over the modulation type for optimized pulse
patterns.
The parameter value refers to the rated line voltage of the power unit.
Recommendation: For power units with controlled regenerative line feedback, a value of approximately 2 % is recommended.
For all other power units, a value of approximately 8 % (as a result of the increased DC link voltage ripple under
load).
Description: Sets bit 0 for recording the power unit in the subgroup for the "offset clocking".
Dependency: Refer to: p1818, p1819
