8.3.1 Installation of EMC Input Filter on Power Input Side
An EMC filter installed between the servo drive and the power supply can not only restrict the interference of
electromagnetic noise in the surrounding environment on the servo drive, but also prevents the interference from
the servo drive on the surrounding equipment.
The IS580 series servo drive satises the requirements of category C2 only with an EMC lter installed on the
power input side. The installation precautions are as follows:
•
Strictly comply with the ratings when using the EMC lter. The EMC lter is category I electric apparatus,
and therefore, the metal housing ground of the lter should be in good contact with the metal ground of the
installation cabinet on a large area, and requires good conductive continuity. Otherwise, it will result in electric
shock or poor EMC effect.
•
The ground of the EMC filter and the PE conductor of the servo drive must be tied to the same common
ground. Otherwise, the EMC effect will be affected seriously.
•
The EMC lter should be installed as close as possible to the power input side of the servo drive.
