Sine-wave filter (option Y15)

This option allows line motors or motors with insulation systems that are not compatible with
drives to be operated with speed control. The sine-wave filter supplies the motors with virtually
sinusoidal motor currents and voltages, which means that line motors can be used. Standard
cables (without EMC shielding) can also be used between the sine-wave filter and the motor.
When sine-wave filters are used, the voltage harmonic distortion at an output frequency of 50
Hz is less than 5%. When the sine-wave filter is used, refer to the performance data (see the
technical specifications). Only work machines with square load characteristic curve (centrifugal
pumps and water turbines) can be operated. Field-weakening operation is not permitted.
Possible rated output frequencies are limited to a range of 30 Hz to max. 66 Hz. The frequency
setting range is 1:10.
