Drive control unit for the ACS580
The ABB 3AXD50000161867 is a drive control unit rated 0.55 kW output at 3.7 A normal use, on a 200–240 V three-phase supply. It sits in the R1 frame size and includes the control unit itself — no additional options module required for basic operation. Communication is MODBUS over the built-in interface; there are 5 digital inputs, 2 digital outputs, 2 analog inputs, and 1 analog output on board.
Three load profiles are defined: light-overload use (PlD) at 0.55 kW / 3.5 A, normal use (Pn) at 0.55 kW / 3.7 A, and heavy-duty use (PhD) at 0.37 kW / 2.4 A. The light-overload and normal ratings overlap at 0.55 kW, but the current difference (3.5 vs 3.7 A) reflects the thermal headroom for occasional overloads. For UL-listed installations, the heavy-duty output is 0.5 Hp at 2.4 A, and light-overload is 0.75 Hp at 3.5 A.
This is an active catalog item — no LTB or phase-out window. It is the control unit only; the power stage and any option modules are ordered separately. For a BOM freeze, the key fit check is the motor current against the heavy-duty rating (2.4 A) for continuous torque, or the normal-use rating (3.7 A) if the load profile is variable torque. The MODBUS interface is fixed; there is no second protocol slot, so if the network requires PROFINET or EtherNet/IP, this unit will not bridge it without an external gateway.
