The ABB 3AXD50000038979 is a general-purpose wall-mounted drive rated for 18.5 kW normal use at 38 A output on a 380-480 V three-phase supply. It includes the control unit.
The normal-use output current of 38 A (In) is the number to match against your motor nameplate. If your application cycles hard, the heavy-duty rating of 31.6 A (IhD) gives you headroom. Light-overload use is rated at 36.1 A (IlD) — same 18.5 kW power as normal use, but with a slightly lower current ceiling. The drive is IP55 and NEMA Type12, so it's fine for dusty or washdown environments indoors. Ambient temperature max is 50 °C, and it's rated for altitudes up to 1000 m without derating.
Installation notes
Wall-mounted in frame R3. The drive has 2 analog inputs and 2 analog outputs, plus 6 digital inputs and 3 digital outputs. Communication is CAN-based — no onboard Ethernet, so if you need fieldbus, plan for an option module. Standby loss is 16 W; power consumption under load is 523 W. The sound level is 76 dB(A) — noticeable in a quiet control room. The battery is a CR2032 lithium coin cell for the real-time clock.
