Pulse Frequency Wobbulation Amplitude / Puls Wobb Ampl; Bi: Offset Calibration Output Current Measurement / Off_Calibr I_Outp; Phase For Pwm Generation Subgroup / Ph For Pwm Subgr - Siemens SINAMICS G150 Manual

Re bit 10 = 1:
Pulse-dropping function activated.
Re bit 12 = 0:
The pulse frequency p1800 can also be synchronously set to the current controller clock cycle (see r0114).
Bit 12 can only be set from 1 to 0 if the pulse frequency p1800 is set synchronously to the current controller clock
cycle. In this case, the gating unit is not switched over.
Re bit 12 = 1:
The pulse frequency p1800 can also be asynchronously set to the current controller clock cycle. In this case, the
effects should be observed (see p1800).
If bit 12 is set to 1, then the gating unit is automatically switched over (p1810.2 = 1). If this is not possible (see above),
then bit 12 cannot be set to 1.
Bit 12 cannot be set to 1, if p1810.3 = 1 is set.
Re bit 15 = 1
For p1802 = 0, 2 and p1803 > 106 %, dynamically, a modulation depth of more than 106 % is permitted. When p1803
is increased, the dynamic modulation depth reserve p1574 should be increased so that the maximum output voltage
r0071 approximately remains the same.

Pulse frequency wobbulation amplitude / Puls wobb ampl

VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Modulation
Not for motor type: -
Min
0 [%]
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)
p1812

BI: Offset calibration output current measurement / Off_calibr I_outp

VECTOR_G Can be changed: T
Data type: Unsigned32 / Binary
P-Group: Modulation
Not for motor type: -
Min
-
Description: Sets the signal source to activate/de-activate 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.

Min
-
Description: Sets bit 0 for recording the power unit in the subgroup for the "offset clocking".
Bit field: Bit
