What the order code is
The ABB ACS880-01-124A-5+B056+N7504+N8010+X1556 is an ACS880-01 series wall-mount drive from the ACS880 family, built around the 124 A frame with four option-code suffixes — +B056, +N7504, +N8010, and +X1556 — layered on the base order code. The +B056 / +N7504 / +N8010 / +X1556 suffix string is the only level of configuration captured on the line; any further hardware or firmware variant has to be read off the drive nameplate against the purchase order.
Mechanical and panel realities
Drive mass is 27.22 kg — heavy enough that two-person handling is the practical rule and the cabinet or wall bracket has to be rated for that load before the unit is lifted into place. Cabinet layout should treat the ACS880-01 frame as the governing footprint; cooling clearance and cable bend radii follow the same family geometry regardless of which current rating sits inside.
Family cross-shop — staying inside the ACS880-01 frame
Inside the same ACS880-01 wall-mount family, the ACS880-01-065A-5 sits at 23.13 kg and the ACS880-01-040A-5 at 18.14 kg — both true same-class alternatives the buyer can weigh when a smaller-frame spare or a lower-current build will satisfy the motor load. Drop-in to a panel cut around one of those frames is not automatic: current rating, depth, and option-code set all have to match the original specification, not just the family prefix.
