In order that the converter service life is not reduced, a line reactor is required for a relative
short-circuit voltage u

Sine-wave lter
Sine-wave lters limit the rate of voltage rise (dv/dt) and the peak voltages at the motor winding.
The sine-wave lter increases the maximum permissible length of the motor cables.

Output reactor
In order to increase the maximum permissible motor cable length you need one or two output
reactors, depending on the converter.
• Frame size AA…frame size C: An output reactor
• Frame size D…frame size F: Two output reactors connected in series
