SINAMICS G List Manual, Edition 12.2004
Description:
Sets the filter time constant of the DC link voltage used to calculate the modulation depth.
Description:
DC link voltage that is used to convert the setpoint voltage into an equivalent modulation depth.
Note:
P1737 can be used for filtering.
Description:
DC link voltage used to determine the maximum possible output voltage.
Description:
Displays the effective modulator mode.
Values:
1:
Flat top modulation (FLB)
2:
Space vector modulation (SVM)
3:
Edge modulation from 28 Hz; 23:3
4:
Edge modulation from 28 Hz; 19:1
5:
Edge modulation from 60 Hz; 17:3
6:
Edge modulation from 60 Hz; 17:1
7:
Edge modulation from 100 Hz; 9:2
8:
Edge modulation from 100 Hz; 9:1
Description:
Sets the minimum ratio between the pulse frequency and the output frequency.
Notice:
If the ratio between the pulse frequency and the output frequency is reduced, then oscillations can occur in the out-
put current that can result in significant levels of current ripple with the appropriate negative effects.
