Usage restrictions for sine-wave filters
The following restrictions must be taken into account when a sine-wave filter is used:
● The output frequency is limited to a maximum of 150 Hz.
● The modulation type is permanently set to space vector modulation without
● Maximum permissible motor cable lengths:
● Other restrictions: Refer to the manuals
Note
If a filter cannot be parameterized (p0230 < 3), this means that a filter has not been provided
for the component. In this case, the drive converter must not be operated with a sine-wave
filter.
