The 3AXD50000038978: This drive carries three duty ratings so you can match it to the load profile without oversizing. Normal use (Pn) is 15 kW at 32 A — that covers constant-torque applications like conveyors or fans running at full speed. Heavy-duty use (PhD) drops to 11.0 kW at 24.6 A, which handles high starting torque or cyclic overloads — think crushers or extruders. Light-overload use (PlD) stays at 15.0 kW but current is 30.4 A, a middle ground for variable-torque loads like pumps.
I/O and communication — what's onboard
Onboard I/O gives you 6 digital inputs and 3 digital outputs plus 2 analog inputs and 2 analog outputs — enough for basic speed reference, run/stop, and feedback without an expansion module. Communication is CAN only; there is no industrial Ethernet interface (0 hardware interfaces for Ethernet). If your control network is PROFINET or EtherNet/IP, you will need an optional fieldbus adapter. The standby loss of 16 W and power consumption of 492 W at rated load help with panel cooling calculations. Ambient temperature limit is 50 °C maximum; derate above that. Altitude rating is 1000 m without derating.
Wall-mounted, IP55 / NEMA Type12 — suitable for indoor locations where hose-down or dust is present. Sound level is 76 dB(A) at full load, which is noticeable in a quiet control room but typical for a 15 kW drive. The lithium coin cell (CR2032, 220 mAh, 3 V) backs the real-time clock; it is field-replaceable. WEEE category 4 (Large Equipment) applies for end-of-life disposal in EU markets.
