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.
