The 3AXD50000874170: The drive includes a control unit, 2 analog inputs and 1 analog output, plus 4 digital inputs and 2 digital outputs. Communication is Modbus (no onboard industrial Ethernet). Standby loss is 23 W; sound level is 66 dB(A). Rated for installation up to 2000 m altitude, 5…95 % RH, and a maximum ambient of 40 °C. Efficiency class IE2, power factor 0.98.
The three overload classes let you match the drive to the load profile. Normal-use (Pn 15 kW, In 32.0 A) covers constant-torque applications at rated current. Light-overload (PlD 15 kW, IlD 30.5 A) gives extra headroom for occasional peak loads. Heavy-duty (PhD 11 kW, IhD 25.0 A) is the conservative rating for high-starting-torque or cyclic loads — use this one if the motor duty cycle is demanding or ambient is near the 40 °C limit. Frame R3 and IP20 open-type mean it mounts in a clean, dry cabinet — not outdoors or in washdown areas. The Modbus interface is fixed; no fieldbus option slot for PROFINET or EtherNet/IP. If the line requires Ethernet-based control, this isn't the variant.
