1) In multimotor systems, the calculated sum of all motor cable lengths must not exceed the
maximum motor cable length given in the table.
2) Longer motor cables cause a motor voltage decrease which limits the available motor power. The
decrease depends on the motor cable length and characteristics. Contact ABB for more
information.
