EMC compatibility and motor cable length

To comply with the European EMC Directive (standard EN 61800-3), use the
following maximum motor cable lengths at 4 kHz switching frequency. See the
table below.

Note 1: In multi-motor system, the sum of all motor cable lengths
shall not exceed that given in the following table.
Note 2: Longer cables cause a motor voltage decrease which
limits the available motor power. The decrease in voltage de-
pends on the motor cable length and characteristics. A sine filter
(optional) at the drive output can also cause a decrease in
voltage. For more information, consult your local ABB Service
representative (http://new.abb.com/channel-partners/search).
*)Conducted and radiated emissions of these motor cable
lengths do not comply with EMC requirements.
