6.4 Motor voltage filter
Advantages of using a motor supply filter:
•
Sinusoidal output voltages to supply electronic devices.
Please note:
•
Install the motor supply filter as close as possible to the inverter.
•
Select the control mode "V/f characteristic control"
(C006=-0-). The "magnetizing current control" form of control is
not permissible.
•
The chopping frequency must be set to 8 kHz (C018 = -4-).
•
The inverter is loaded additionally with approximately 10% of the
rated current of the motor supply filter.
•
The voltage drop across the motor supply filter at rated current
and rated frequency (f
d
= 50 Hz) is 7% of the inverter output
voltage.
•
The maximum permissible output frequency is 120 Hz.
•
With unscreened motor cables it should be tested whether the
system complies with the interference levels required for the CE-
EMC conformity.
