Duty ratings — normal, heavy, light
The 3AXD50000038980: Normal use (Pn/In) is 22 kW / 45 A. Light-overload use holds at 22.0 kW / 42.8 A, so you get full power but with a slightly lower current ceiling than the normal-use curve. Pick your application class; the drive's thermal model expects the right one.
I/O and comms — what's on the board
Six digital inputs, three digital outputs, two analog inputs, two analog outputs. CAN protocol on the hardware interface — no onboard Industrial Ethernet. That matters if you're dropping this into a PROFINET or EtherNet/IP line; you'll need the optional fieldbus adapter module. The 16 W standby loss is worth noting if the drive sits idle for long stretches.
Environmental limits
Rated for 50 °C max ambient, 95 % RH non-condensing, altitude 1000 m without derating. IE2 efficiency level. Sound level 76 dB(A) — noticeable in a quiet space; plan ear protection if it's near a workstation.
