The 3AXD50000031888: Normal-use output (1.1 kW, 3.3 A) covers constant-torque applications like fans and pumps at full speed. Heavy-duty use (0.75 kW, 2.6 A) gives headroom for variable-torque loads or cyclic duty where peak current matters. The light-overload rating (1.1 kW, 3.1 A) mirrors normal use but with a slightly lower current ceiling — useful when the motor nameplate sits right at the boundary. Under UL listing the heavy-duty power is 1 Hp (2.1 A) and light-overload is 1.5 Hp — a reminder that NEC branch-circuit sizing may differ from IEC ratings.
I/O and fieldbus at a glance
Two analog inputs and one analog output handle speed reference and feedback. Five digital inputs and two digital outputs cover start/stop, fault reset, and status. The Modbus RTU port is the standard fieldbus interface; no onboard Ethernet, so if you need PROFINET or EtherNet/IP you'll add an optional module. Power consumption from the control supply is 55 W.
