Note: In multimotor systems, the calculated sum of all motor cable lengths must not exceed
the maximum motor cable length given in the table.
EMC compatibility and motor cable length
To comply with the EMC limits in the European EMC Directive (standard IEC/EN 61800-3),
do not exceed these maximum motor cable lengths. They are valid for 4 kHz switching
frequency.

Category C1 with conducted emissions only. Radiated emissions are not compatible when measured with the standard
emission measurement setup and must be measured on cabinet and machine installations for each case.
Note:
• For 3-phase 380…400 V drives, the maximum motor cable lengths are according to C3
in the above table with an internal EMC filter.
Brake resistor connection data
The brake resistor output is conditionally short-circuit proof by IEC/EN 61800-5-1
and UL 61800-5-1.
