13.5.7 RFI filters
According to the application, different measures for reducing the mains current and for
radio interference suppression are required on the supply side for servo systems. As a rule,
these measures are not mandatory, but protect the universal application of a servo system.
Lenze offers a built−on filter for each power supply module for the interference level A. The
RFI filters are designed for the ECS power supply module assigned and up to 10 axes with
a motor cable length of 25 m each (Lenze system cable). The interference level A is
observed as long as the motor cable length per axis module is 25 m at a maximum (Lenze
sytem cables) and the number of the ECS axis modules is maximally 10.
