Maximum motor cable length is determined by the drive
’s operational factors. Contact your local
ABB representative for the exact maximum lengths when using external EMC filters
Note 1: In multimotor systems, the calculated sum of all motor cable lengths must not
exceed the maximum motor cable length given in the table.
Note 2: The internal EMC filter must be disconnected by removing the EMC screw (see
section Connection procedure on page 42 ) while using an external EMC filter.
Note 3: Radiated emissions are according to C2 with and without an external EMC filter.
Note 4 : Category C1 with conducted emissions only. Radiated emissions are not
compatible when measured with standard emission measurement setup and should be
checked or measured on cabinet and machine installations case by case.
