5.3 Motors and cables
With longer motor cables the resulting commutation currents can affect the control quality
and lead to EMC faults. Use the tables below to check whether motor chokes or mains filters
have to be used in your application. When selecting the control cabinet ensure that there is
adequate space for motor chokes, mains filters, etc.
Lay the power and signal cables in separate metal cable ducts or, if both types of cable use
the same metal cable duct, make sure there is an earthed metal dividing wall between the
cables.
