The 3AXD50000034630: Normal-use current of 293 A is the number to size supply conductors and upstream protection against. If your load profile cycles hard (conveyor start, sludge rakes), the heavy-duty 246 A line is the one that governs thermal capacity in the drive — that's the rating that keeps the IGBTs alive under repeated overload. Light-overload at 278 A splits the difference for intermittent high-torque demands that don't sustain. Standby loss is 47 W, so the drive idles warm but not hot; factor that into panel ventilation if you're stacking multiple units.
IP55 and NEMA Type 12 mean hose-down and dust aren't an issue — this drive lives on the plant floor, not in a conditioned electrical room. Maximum ambient 40 °C, altitude 4000 m before derating. Operating humidity 5–95% non-condensing. Sound level 65 dB(A) — noticeable in a quiet space but not loud for a 160 kW drive. Wall-mount only; no flange kit in the box, though the R8 frame accepts one if you need back-channel cooling.
Two analog inputs, two analog outputs — enough for a pressure transducer and a speed reference, plus feedback. Six digital inputs and three digital outputs handle start/stop, fault reset, and a run status relay. Communication is CAN; no onboard Ethernet, so if you need Modbus TCP or PROFINET, plan for an option module. The control unit is included, so you're not chasing a separate order line for the brains.
