If a sine-wave filter is connected to the output of the Power Module or Motor Module, the voltage between the motor terminals is virtually sinusoidal. This reduces the voltage load on the motor windings and prevents motor noise induced by the pulse frequency.

The pulse frequency of the modules must be set to 4 kHz for the sine-wave filters. The max. output frequency with sine-wave filter is limited to 150 Hz.

As a result, the max. possible output current and the max. achievable output voltage of the units are reduced. The voltage drops across the sine-wave filter, a factor which must also be taken into account in the drive design.

A sine-wave filter must be installed as close as possible to the Motor Module or Power Module.

It is only permissible to operate the sine-wave filter when the motor is connected (sine-wave filters are not no-load proof)!

For additional information on sine-wave filters, please refer to the SINAMICS Low Voltage Engineering Manual.
