The 3AXD50000038965: Normal-use output is 1.1 kW at 3.3 A; heavy-duty use drops to 0.8 kW at 2.6 A. Light-overload use sits at 1.1 kW and 3.1 A, essentially the same as normal use, so the headroom between normal and heavy-duty is the real selection gate.
Where it lives: enclosure, mounting, and environment
Wall-mounted, IP55, NEMA 12. That means it's built to take hose-down and dust — fine for a mill floor or a feed mill, not for submersion. Rated for 1000 m altitude without derating; max ambient 50 °C. Standby loss is 14 W, so it's not dumping heat when the motor is stopped. Sound level is 59 dB(A) — noticeable but not shouty in a machine room.
I/O and communication — what's on board
Two analog inputs, two analog outputs. Six digital inputs and three digital outputs. Communication is CAN — no onboard Industrial Ethernet, so if your control network runs PROFINET or EtherNet/IP, you'll need an option module or a gateway. The drive includes a control unit and a lithium coin cell (CR2032, 220 mAh) for real-time clock backup.
