What this drive module is and what it delivers
The ABB 3AXD50000049063 is a drive module in frame size R11, delivering 500 kW normal-use output at 880 A, with a heavy-duty rating of 400 kW at 725 A. It runs on a 3-phase 380–480 V input and includes the control unit as standard. The module is rated for continuous duty at a maximum ambient temperature of 40 °C, with an altitude limit of 1000 m. It carries an IE2 efficiency level and a power factor of 0.98. Enclosure is IP00, NEMA Open Type, so it needs a cabinet for dust and touch protection. Standby loss sits at 615 W, and sound pressure is 71 dB(A) — worth factoring into panel cooling and noise budgets.
I/O and communication — what is on board
On the control side, the module provides 2 analog inputs, 2 analog outputs, and 6 digital inputs with 3 digital outputs. Communication is via CAN; there is no onboard industrial Ethernet interface. A lithium coin cell (CR2032, 220 mAh, 3 V) backs up the real-time clock and parameter storage. The battery is field-replaceable.
Duty ratings — normal, heavy, light-overload
Three duty classes are specified: normal use at 500 kW / 880 A, light-overload use at 500 kW / 865 A, and heavy-duty use at 400 kW / 725 A. The UL listing mirrors these: 700 Hp / 880 A normal, 500 Hp / 625 A heavy-duty. Normal-use 880 A suits variable-torque fans and pumps.
