The sine-wave filter at the inverter 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.
From 110 kW power rating of the Power Modules (according to the rating plate) only
4 kHz is permissible.
● The inverter power is reduced by 5%.
● The maximum output frequency of the inverter 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.
