5.3 Motors and cables
With longer motor cables the resulting commutation currents can lead to EMC faults. Use
the tables below to check whether mains chokes or mains filters have to be used in your
application. When selecting the control cabinet ensure that there is adequate space for
mains chokes and 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.
Note
Motor chokes
For the AX5140 series no motor choke is required.
Maximum cable length (including extensions) for a rated motor voltage up to 400 V
