Current
Frames R1i…R4i: 4.5 kHz (typical)Switching frequency
Frames R5i…R8i: 3 kHz (typical)
The switching frequency can vary per frame and voltage. For exact values, please
contact your local ABB representative.
*Frames R1i…R2i: 150 m (492 ft)Maximum recommended
motor cable length
*Frames R3i…R7i: 300 m (984 ft)
Frame R8i and multiples: 500 m (1640 ft)
*Tested with 100 m (328 ft) for EMC Category C3. See standards and markings
information in Electrical planning instructions for ACS880 multidrive cabinets and
modules (3AUA0000102324 [English]).
Note: Longer 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.
