100,000 rms symmetrical amperes at 600 V maximum when the input cable is
protected with T class fuses.

) 0…500 Hz
• For higher operational output frequencies, contact your local ABB
representative.
• Operation above 150 Hz may require type-specific derating. For more
information, contact your local ABB representative.
Current See the rating tables.
Switching frequency 3 kHz (typical). The switching frequency can vary per frame and voltage. For
exact values, contact your local ABB representative.
Maximum recommended
motor cable length
500 m (1640 ft).
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.
Note: With motor cables longer than 150 m (492 ft) the EMC Directive
requirements may not be fulfilled.
