6.4 Sine filter
Advantages of using a sine filter:
l Sinusoidal output voltages to supply electronie devices.
Please note:
l Irrstall the sine filter as close as possibie to the controller.
l Select the control mode “V/f-characteristic control”
(COO6=-0-). The “magnetizing-current control” form of control is
not permissibie.
l The chopper frequency must be set to 8 kHz (CO1 8 = -4-).
L The controller is loaded additionally with approximately 10% of
the rated current of the sine filter.
l The voltage drop across the sine filter at rated current and rated
frequency (fd = 50 Hz) is 7% of the Controller output voltage.
l The maximum permissible output frequency is 120 Hz.
l With unscreened motor cables it shouid be tested whether the
System camplies with the interference Levels required for the
CE-EMC conformity.
