What it is and where it drops in the panel
The ABB ACS180-04N-12A6-4 is an LV AC machinery drive module in the ACS180 family, sized in the R2 frame as a panel-mount module rather than a standalone drive with an integrated operator keypad. The enclosure is IP20 open type, so the drive belongs inside a cabinet — it is not rated for direct field mounting on the machine surface. The ACS180 line is built for general-purpose machinery speed control, the kind of low-voltage three-phase motor duty that shows up across packaging lines, fans, conveyors, and small pump skids.
Mains side: 400 V class, three-phase
The drive is rated for installation up to 2000 m altitude, which is the usual threshold above which the integrator has to apply thermal derating per the ABB curve. Stated power factor is 0.98 at the line side, which keeps the upstream supply-side compensation modest compared with a six-pulse rectifier design. Cooling noise is published at 62 dB(A), worth flagging for a cabinet sited close to a control room wall or operator workstation.
Control side: analog I/O and MODBUS
The control slice is fixed to MODBUS on the communications port — there is no fieldbus option card in this build, and any PROFINET or EtherNet/IP gateway has to live outside the drive. Two analog inputs and one analog output are available on the module, enough for a reference signal and a feedback loop on a simple V/Hz line, but tight if the application also wants a process transmitter and a follower speed reference. The module ships with no battery or cell fitted, so the integrator's compliance pack does not need a lithium-battery handling note for this drive.
