motor cable length
Scalar control: 500 m (1640 ft)
Note: With motor cables longer than 100 m (328 ft), the EMC Directive requirements
may not be fulfilled.
Note: Long 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. Note that a sine filter (optional) at the drive
output also causes a voltage decrease.
For drive modules without d u /d t filter: 2 m (7 ft) from each drive module to the
motor or 4 m (13 ft) between the drive modules. The motor cabling must be sym-
metrical. See also section
