The ABB 3AXD50000161904 is the control unit for a general-purpose drive, R1 frame size. It handles a 3-phase 200–240 V input and delivers 2.2 kW normal-duty output at 9.8 A. The unit includes the control board and firmware; the power stage is a separate module. Communication is MODBUS via the built-in port — no Ethernet interface on this variant.
Light-overload (9.3 A) suits variable-torque fans and centrifugal pumps. The normal-duty 9.8 A rating is for standard variable-torque applications with occasional overload. Standby loss is 15 W, sound level 63.1 dB(A), and efficiency meets IE2. Ambient temperature max is 50 °C; altitude rated to 1000 m without derating. Enclosure is IP20 open type — panel-mount only, no standalone floor use.
The control unit includes 2 analog inputs, 1 analog output, 5 digital inputs, and 2 digital outputs. Humidity range 5–95% non-condensing. No battery inside — no periodic replacement.
