The 3AXD50000707270: The drive carries three output current ratings that map to different load profiles. Normal use (In) is 7.2 A at 3 kW — that's the continuous rating for a standard centrifugal pump curve. Light-overload use (IlD) is 6.8 A at 3 kW, a slight reduction for applications with modest transient demands. Heavy-duty use (IhD) drops to 5.6 A at 2.2 kW, meant for constant-torque loads or higher ambient conditions where you need thermal headroom.
Onboard CAN protocol handles drive-to-drive or drive-to-controller links. The module includes 2 analog inputs and 2 analog outputs, plus 6 digital inputs and 3 digital outputs — enough for basic pump control (start/stop, speed reference, feedback) without an extra I/O block. No industrial Ethernet interface is fitted, so if you need PROFINET or EtherNet/IP, plan for an external gateway or option module.
Power consumption and standby loss
The drive draws 100 W under load (Pcons) and 15 W in standby. That standby figure matters for off-grid solar installations where every watt of quiescent draw cuts into battery capacity — 15 W is modest but not negligible if the pump sits idle overnight.
