The 3AXD50000145720: The normal-duty 870 A is your continuous motor current for a 500 kW load — that's the number to size the input cabling and fusing. Heavy-duty 651 A at 355 kW covers constant-torque applications like conveyors or extruders where the drive has to hold rated torque across the speed range. Light-overload 835 A at 450 kW sits between the two, useful for pumps and fans with occasional overload. The 603 kV·A apparent power tells you the transformer or generator feeding it needs to handle that kVA, not just the kW. IP22 and NEMA Type 1 enclosure. Ambient max 40 °C, altitude 1000 m, humidity 5–95% non-condensing.
Four analog inputs and four analog outputs give you room for speed reference, feedback, and process signals without an expansion module. Digital I/O: 14 inputs, 10 outputs — enough for basic start/stop, fault reset, and run-permissive logic without a separate PLC for the drive cell. Communication is CAN only; no onboard Industrial Ethernet, so if you need PROFINET or EtherNet/IP you'll need an optional fieldbus adapter. The control unit is included in the package.
What's inside that matters for bench work
Two lithium coin cells (BR2032, 3 V, 200 mAh each) back up the parameter memory and real-time clock. They're replaceable — you'll see them on the control board when the drive throws a parameter-checksum fault after a long power-down. Sound level 75 dB(A) at full load, so ear protection if you're standing next to it in a small room. Power factor is unity (1) at rated conditions, a side effect of the regenerative topology.
