6.4 Sinusoidal filter
Description
The sine-wave 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 sine-wave filter is connected to the Power Module or Motor Module, the converter must
be activated during commissioning (p0230 = 3) to prevent the filter from being destroyed.
If a sine-wave filter is connected to the Power Module or Motor Module, the Power Module
or Motor Module must not be operated without a connected motor because otherwise the
filter can be destroyed.

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correctly because the signals from the deactivated drive are no longer updated.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: /FH1/
