Operational functionality and motor cable lengthMaximum recommended motor
cable length
The drive is designed to operate with optimum performance
with the following maximum motor cable lengths.
Note: Conducted and radiated emissions of these motor
cable lengths do not comply with EMC requirements.

*For 600 V drives the maximum motor cable length is 100 m
(330 ft) for frame R2 and 200 m (660 ft) for frame R3.
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.
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 your local ABB representative for more inform-
ation.
3. When using longer motor cables than 50 m (165 ft), 8
and 12 kHz switching frequencies are not allowed. With
motor cable length over 100 m, disconnect EMC DC
screw if applicable.
4. Acceptable motor cable length for motor manufactures
may be different. Check with specific motor manufac-
turer for maximum allowable distance.
