5.7.2 Use of EMC-Correct Cables
Danfoss recommends braided shielded/armored cables to
optimize 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
impedance (Z
T
). The shield of a cable is normally designed
to reduce the transfer of electric noise; however, a shield
with a lower transfer impedance (Z
T
) value is more
effective than a shield with a higher transfer impedance
(Z
T
).
Transfer impedance (Z
T
) is rarely stated by cable manufac-
turers, but it is often possible to estimate transfer
impedance (Z
T
) by assessing the physical design of the
cable.
