Sinusoidal filter

Description
The sinusoidal filter limits the rate of rise of voltage and the capacitive charge/discharge
currents that usually occur with inverter operation. They also prevent additional noise caused
by the pulse frequency. The service life of the motor is the same as that with direct line
operation.
CAUTION
If a sinusoidal filter is connected to the converter, the converter must be activated during
commissioning to prevent the filter from being destroyed.
Usage restrictions for sinusoidal filters
The following restrictions must be taken into account when a sinusoidal 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

CAUTION
If a drive in a Safety Integrated line-up is deactivated via p0105, r9774 is not read
correctly because the signals from the deactivated drive are no longer updated.
Remedy: Remove this drive from the group before you deactivate it. See also: Function
Manual (FH1), chapter Safety Integrated
overmodulation. This reduces the maximum output voltage to approx. 85 % of the rated
output voltage.
