Duty ratings and load handling
The 3AXD50001057473: Three duty ratings are on record: normal-use at 500 kW / 710 A, light-overload at 450 kW / 682 A, and heavy-duty at 350 kW / 531 A. The UL listing mirrors these at 700 Hp / 780 A for normal, 500 Hp / 682 A for light-overload, and 450 Hp / 531 A for heavy-duty.
Physical and environmental specs
The drive sits in an R8i+R8i dual-frame configuration, NEMA Type 1 enclosure with IP22 protection. Maximum ambient temperature is 40 °C, altitude limited to 1000 m without derating. Operating humidity spans 5-95% RH. Sound level is 75 dB(A) — expect that in a drive room without acoustic treatment.
Onboard I/O includes 4 analog inputs, 4 analog outputs, and 14 digital inputs plus 10 digital outputs. Communication is via CAN bus; there are no onboard Industrial Ethernet interfaces. The control unit is included with the drive, and it uses two BR2032 lithium coin cells for backup.
