EMC Precautions
The following EMC precautions are recommended in order to achieve interference-free operation of the
CANopen network. Additional EMC information is available in the FC 300 series Operating Instructions and
FC 300 Design Guide.
NB!:
Relevant national and local regulations, for example regarding protective earth connection, must be
observed.
The CANopen communication cable must be kept away from motor and brake resistor cables to avoid
coupling of high frequency noise from one cable to the other. Normally a distance of 200 mm (8 inches) is
sufficient, but it is generally recommended to keep the greatest possible distance between the cables,
especially where cables run in parallel over long distances. If the CANopen cable has to cross a motor and
brake resistor cable they must cross each other at an angle of 90 degrees.
