Use of emc-correct cables
Braided screened/armoured cables are recommended
to optimise EMC immunity of the control cables and
the EMC emission from the motor cables.
The ability of a cable to reduce the in- and outgoing
radiation of electric noise depends on the transfer im-
pedance (Z
T
). The screen of a cable is normally de-
signed to reduce the transfer of electric noise;
however, a screen with a lower transfer impedance
(Z
T
) value is more effective than a screen with a higher
transfer impedance (Z
T
).
