8.1 OPTIONAL ITEMS

In order to ensure the proper operation, the optional cards are installed by the factory and must not be installed
by the user. Some models cannot receive all the options presented.
items available for each servo drive model.
The servo drive code is presented in

8.1.1 Internal RFI filter

The filter is available in models SCA06_______C3. Its function is to reduce the conducted disturbance of the servo
drive to the power grid in the high frequency band (>150 kHz).
It is necessary so as to meet the maximum levels of conducted emission established by standards of electromagnetic
compatibility, such as EN 61800-3 and EN 55011.
For the proper operation, it is necessary the installation of the servo drive, servomotor, cables, etc. as presented
in section 3.2 ELECTRICAL INSTALLATION on page
As this filter is composed of capacitors connected between the input phases and the Ground, there will be a
leakage current. The value of the leakage current is listed in
interrupter (DR) must be dimensioned to stand the leakage current without actuating.
In case this leakage current is not desired, the EMC filter may be disabled by removing the screw, as shown in
Figure 8.1 on page 8-2. In this case, the filter will remain inactive and the electromagnetic noise emission levels
will be higher, and it can significantly interfere in equipment near or connected to the same power supply. WEG
does not recommend this kind of installation.
