What this order code is
The ABB ACS880-01-124A-5+B056+E200 is a wall-mount single drive in the ACS880-01 family, specified at 75 kW by ASEA BROWN BOVERI. It carries the option suffix string +B056+E200, which sits inside the same ACS880-01 frame as the standard catalog codes — so the panel cutout, gland layout and control terminal map of the base drive apply. The drive weighs 42.20 kgs, which puts it firmly in hoist-or-two-man territory on a panel build; the wireman should plan a lifting point and check the cabinet floor loading before the unit goes in.
Where the ACS880-01 class fits
ACS880-01 drives are the single-drive, wall-mount tier of the ACS880 platform — used where one motor is fed from one cabinet-mounted inverter rather than a common-DC multi-drive architecture.
