Sine-wave filter

The sine-wave filter at the converter output limits the voltage rate of rise and the peak voltages
at the motor winding. The maximum permissible length of motor feeder cables is increased to
300 m.
The following applies when using a sine-wave filter:
• Operation is only permissible with pulse frequencies from 4 kHz to 8 kHz.
• The converter power is reduced by 5%.
• The maximum output frequency of the converter is 150 Hz at 380 V to 480 V.
• Operation and commissioning may only be performed with the motor connected, as the sine-
wave filter is not no-load proof.
• An output reactor is superfluous.
