The ABB 3AXD50000049062 is an R11-frame drive module rated for 450 kW normal-use output and 820 A continuous current. It takes 380-480 V three-phase input at 47.5-63 Hz and delivers 568 kVA apparent power. The heavy-duty rating is 355 kW at 625 A, and the light-overload rating matches the normal-use power at 450 kW with 810 A output. This is a current-production part — no phase-out or last-time-buy to plan around.
The three duty ratings let you match the drive to the application without over-specifying. Normal use (450 kW, 820 A) covers constant-torque loads like conveyors and pumps running at full nameplate. Heavy-duty use (355 kW, 625 A) applies to higher-torque profiles — crushers, extruders, or any application where the motor draws more current per kW. Light-overload use (450 kW, 810 A) is for variable-torque loads like fans and centrifugal pumps where peak current is brief. The UL ratings track identically: 700 Hp normal-use, 500 Hp heavy-duty, with the same current figures.
Physical and environmental constraints
The module is IP00 open type, so it needs a clean, dry enclosure — no washdown areas or dusty environments without a proper cabinet. Maximum ambient temperature is 40 °C, and the altitude rating is 1000 m without derating. Operating humidity range is 5-95% RH. Standby loss is 466 W, which adds to the cabinet heat load. Sound level is 72 dB(A) — noticeable in a quiet room but typical for an R11 frame at full load. The unit includes a control module and a lithium coin cell (CR2032, 220 mAh) for parameter backup.
The drive communicates via CAN bus. It has 2 analog inputs, 2 analog outputs, and 6 digital inputs plus 3 digital outputs. There are no built-in Industrial Ethernet interfaces on this module — any network connectivity requires an optional fieldbus adapter. The 6/3 digital I/O count is enough for basic start/stop, speed reference, and fault feedback without an external I/O block.
