RFI filter
The measures required for servo systems on the mains side
in order to reduce the mains current and for interference
suppression will vary depending on the area of application.
Although these measures are not usually essential, they will
enable universal use of a servo system.
RFI filters and mains filters enable compliance with the inter-
ference voltage categories of the European standard EN
61800-3. There a distinction is drawn between category C1
and category C2.
RFI filter ECSZZ020x4B
Category C1
describes the use on public supply networks.
Category C2
describes the use of drives which are intended
to be used for industrial purposes in areas also comprising
residential areas.
The use of Lenze mains filters type ECSZZ ensures compliance
with the requirements of category C1.

(Lenze system cable). If your motor cables are longer than 25
m, please contact your local Lenze sales representative.

Interference filter for SinCos encoder
If the connection between the motor cable shield and PE is
not large enough, this may cause interference on the encoder

Cos encoders in particular if you are using long motor cables
and the earthing conditions are not ideal. The filter is then
