What the part is
The ABB ACQ580-01-12A7-4 is a wall-mounted drive from the ACQ580 series, catalogued under Motors & Motor Controls › Drives › Motor Drives for pump, fan, and HVAC motor duty rather than general industrial motion control. Listed mass is 2.22 kgs, which puts it in the small-frame wall-mount class — one technician can hang it on the back panel, but the sub-panel still wants proper anchors because an ACQ chassis heavier than a relay block can fatigue thin sheet metal over time.
Where the ACQ580 class sits on a BOM
ACQ580 drives are the ABB line targeted at water/wastewater, HVAC, and constant-torque / quadratic-torque pump and fan loads, so the firmware and I/O defaults assume a process loop (PID, sleep/boost, multi-pump staging) rather than a high-dynamic servo or hoist profile. For pump and fan duty, the derating items on FAT are cabinet ambient, motor cable length against the drive's reflected-wave limit, and any output filter the application needs.
Cross-shop against the ACS580-01-031A-2
The closest same-class wall-mount ABB drive to put on a cross-shop is the ACS580-01-031A-2 — both are wall-mount general-purpose ABB drives on the all-compatible platform, so the footprint family and parameter tree are close enough that a panel wired for one usually accepts the other without re-engineering the gland layout, while the ACQ580 is the firmware-skewed variant for pump and fan and the ACS580-01-031A-2 sits at 2.99 kgs in a slightly larger frame. The frame and weight class delta between 2.22 kgs and 2.99 kgs is real but not a panel-layout blocker — it changes the sub-panel anchor pattern and the cooling clearance, not the wiring philosophy, so a drop-in swap from an ACS580 to this ACQ580 is a parameter and macro change more than a mechanical rebuild.
