2. EMC countermeasure examples
Regarding EMC Directive, the customer's final product (entire system) including the OMRON robot must provide the
necessary countermeasures. We at OMRON determine a model for single units of OMRON robots (controller, robot,
and peripheral device) and verify that it complies with the relevant standards of EMC Directive.
In order to ensure the customer's final product (entire system) complies with EMC Directive, the customer should take
appropriate EMC countermeasures. Typical EMC countermeasures for a single unit of OMRON robot are shown for
reference.
CAUTION
The following description and circuits are typical countermeasures used when the robot and controller are tested under OMRON
installation conditions. When the robot and controller are used while installed in the customer's system, the actual test results may differ
depending on installation conditions.

CAUTION
As shown in the following figure, the ferrite cores and noise filter on the controller side should be placed as close to the controller body
as possible. The ferrite cores on the robot side should be placed as close to the robot body as possible.
