4.5 EMC

4.5.1 Definition
Electromagnetic compatibility (EMC) describes the ability of electronic and electrical devices
or systems to work properly in the electromagnetic environment and not to generate
electromagnetic interference that influences other local devices or systems.
In other words, EMC includes two aspects: The electromagnetic interference generated by a
device or system must be restricted within a certain limit; the device or system must have
sufficient immunity to the electromagnetic interference in the environment.
4.5.2 Installation Environment
The system manufacturer using the servo drive is responsible for compliance of the system with
the European EMC directives. Based on the application of the system, the integrator must
ensure that the system complies with standard EN 61800-3: 2004 Category C2, C3 or C4.
The system (machinery or appliance) installed with the servo drive must also have the CE mark.
The system integrator is responsible for compliance of the system with the EMC directives and
standard EN 61800-3: 2004 Category C2.
If applied in the first environment, the servo drive may generate radio interference. Besides the
CE compliance described in this chapter, users must take measures to avoid such interference, if
necessary.
4.5.3 Selection and Installation of Peripheral EMC Devices
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 prevent the interference from the servo drive on the surrounding equipment. FL20 works
with external filter and input filter according to different power rating. The installation
precautions are as follows.
1) Strictly comply with the ratings when using the EMC filter. The EMC filter is category I
electric apparatus, and therefore, the metal housing ground of the filter 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.
2) The ground of the EMC filter and the PE conductor of the servo drive must be tied to the
