Variable frequency drives are compared by rated motor power (kW at 400 V three-phase, or at 230 V single-phase for small drives), the rated output current, the supply voltage class (1 × 200–240 V, 3 × 380–480 V, 3 × 500–690 V), the overload duty (normal duty 110 % / heavy duty 150 % for 60 s), the enclosure rating (IP20 cabinet, IP55/IP66 wall mount) and the built-in EMC filter class. The table groups the catalogue by kW and voltage class across ABB ACS180/ACS380/ACS580/ACS880, Schneider Altivar ATV320/ATV340/ATV630/ATV930, Siemens SINAMICS V20/G120/G120C/G120X, Danfoss VLT Micro FC 51/HVAC FC 102/AQUA FC 202/AutomationDrive FC 302, Eaton DC1/DA1/DG1 and Omron MX2/RX2 so an equivalent-rated drive can be quoted.
A drive rated in kW at heavy duty typically carries the next higher normal-duty rating; compare rated output current, not nameplate kW alone. Fieldbus (PROFINET, EtherNet/IP, Modbus TCP), safe torque off (STO) and braking chopper availability differ between series and frame sizes.
