What lands in the cabinet
The ABB ACQ580-01-065A-4+N7573 is the ACQ580 series wall-mount drive with the +N7573 option suffix, configured into a single order code from the manufacturer. It sits in the drive class for motor control on pumps, fans, and similar variable-torque loads — the ACQ580 family is ABB's purpose-built line for water, wastewater, and HVAC applications, distinct from the general-purpose ACS580 it shares a frame platform with. Mass is listed at 21.32 kgs, which is a real handling number for a single-person lift into a wall-mount cabinet — plan the mounting studs and the gland-plate cable entry before the crate arrives, not after.
Frame share with ACS580 — confirm intent before the swap
ACQ580 firmware is tuned for pump and fan curves with built-in helpers for multi-pump staging, sensor-less flow calculation, and HVAC-specific protections; ACS580 firmware is the general-purpose profile. The hardware is mechanically compatible across the two, but the application macros, default I/O mapping, and assistant panel menus are not — a panel specified around ACS580 will not drop in the ACQ580 without re-commissioning the parameters and re-validating the application logic.
