What the order code points to
The ABB ACH580-01-07A6-4+B056 is an ACH580-series variable-frequency drive in the Motor Drives class. The +B056 suffix is an option-code string layered on the base drive — relevant when the panel builder matches the configured variant against the BOM line, not the bare catalog number. At 4.51 kgs the unit sits in the wall-mount frame used for fan, pump and HVAC duties. One person can shoulder it onto a DIN cutout or wall plate; no spreader bar, no second tech required.
Sourcing posture and lifecycle
Specify the full order string on the RFQ. The +B056 suffix is part of the option-coded MPN; a base drive alone will not match a panel BOM line that was quoted against the suffixed variant.
Sizing context against same-family siblings
The next step up in the same series is ACH580-01-014A-4 at 6.80 kgs. It shares the wall-mount pattern; the current rating differs, so the swap is a motor-size decision. ACH580-01-023A-4 sits further up the same family at 6.80 kgs. ACS580-01-031A-2 belongs to the ACS580 general-purpose platform at 2.99 kgs, a different family and a different supply class.
Integration checklist when this drive hits the panel
Cabinet layout: at 4.51 kgs on a wall-mount frame, allow clear cable-bend space above and below for the line and motor glands; the ACH580 platform is convection-cooled across this frame, so blanking plates above and below the unit matter for the thermal curve to hold.
