Danfoss VLT AutomationDrive FC 300 User Manual

14-50 RFI Filter
This parameter is only available for FC 302. It is not relevant toFC
301 due to different design and shorter motor cables.
Option: Function:
[0] Off
Select [0] Off if the frequency converter is fed by an
isolated mains source (IT mains).
If a filter is used, select Off [0] during charging to
prevent a high leakage current making the RCD
switch.
In this mode, the internal RFI filter capacitors between
chassis and the mains RFI filter circuit are cut-out to
reduce the ground capacity currents.
[1] * On
Select [1] On to ensure that the frequency converter
complies with EMC standards.

6.2 How to Programme the Active Filter
The factory settings for the filter part of the Low Harmonic
Drive are chosen for optimal operation with a minimum of
additional programming. All CT-values, as well as
frequency, voltage levels and other values directly linked
to the drive configuration are pre-set.
It is not recommended to change any other parameters
influencing the filter operation. However, selection of read-
outs and what information to be displayed on the LCP
status lines can be made to fit individual preferences.
To set up the filter two steps are necessary:
•
Change the nominal voltage in 300-10 Active Filter
Nominal Voltage
•
Make sure the filter is in auto mode (press [Auto
On])

6.2.1 Using the Low Harmonic Drive in NPN
Mode
The default setting for 5-00 Digital I/O Mode is PNP mode.
If NPN mode is desired, it is necessary to change the
wiring in the filter part of the Low Harmonic Drive. Before
