Duty ratings — normal, heavy, light overload
The 3AXD50000145829: Three duty curves are listed. Normal use (Pn) delivers 710 kW / 1010 A; heavy-duty (PhD) drops to 500 kW / 755 A for constant-torque loads like conveyors or extruders; light-overload (PlD) sits at 630 kW / 970 A. The UL column mirrors these: 900 Hp normal, 600 Hp heavy, 800 Hp light. If your application is a pump or fan with variable torque, the normal-use figure is your sizing target. For a crusher or press, size against the heavy-duty line.
Enclosure, protection, and environment
IP22 with NEMA Type 1 — suitable for indoor, dry locations where a finger probe is the main concern, not dust or hose-down. Maximum ambient 40 °C, altitude 1000 m without derating. Operating humidity 5–95% non-condensing. Sound pressure at 77 dB(A) — noticeable in a quiet control room; ear protection not mandatory but the hum is there.
Four analog inputs, four analog outputs, 14 digital inputs / 10 digital outputs. Communication is CAN-based — no onboard Industrial Ethernet port (0 hardware interfaces for Ethernet). If your plant runs PROFINET or EtherNet/IP, you will need an optional fieldbus adapter module. The I/O count is generous for a drive this size; you can handle most feedback and control signals without an external I/O block.
