Sinusoidal Filter (Option L15)
Description
The sine-wave filter limits the voltage gradient and the capacitive charge/discharge currents
which usually occur with inverter operation. It also prevents additional noise caused by the
pulse frequency. The service life of the motor is as long as that attained with direct mains
operation.
CAUTION
If a sine-wave filter is connected to the converter, the converter must be activated during
commissioning to prevent the filter from being destroyed (see "Commissioning").
CAUTION
When using a sine-wave filter, the drive must not be operated without a connected motor as
otherwise the filter could be destroyed.
