• For higher operational output frequencies, please contact your local ABB repres-
entative.
• Operation above 150 Hz may require type-specific derating. For more information,
contact your local ABB representative.
See the rating tables. Current
3 kHz (typical). The switching frequency can vary per frame and voltage. For exact
values, please contact your local ABB representative. Switching frequency

Note:
With motor cables longer than 150 m (492 ft) the EMC Directive requirements may
not be fulfilled.
