What this line item is
The ABB ACS800-DEMAG 01-0011-3+E200+L502+N672+P901+R721 is a frequency inverter carrying the long-form DEMAG-flavored option string that a maintenance requisition will spell out exactly — E200, L502, N672, P901, and R721 each sit on the build sheet and must be reproduced verbatim on any replacement order.
What the build-sheet suffixes mean to the buyer
The five suffix codes are part of the order code itself, not optional accessories — the panel backplane, control terminal block, and any fieldbus card slot are dictated by the +E200 / +L502 / +N672 / +P901 / +R721 build, so any cross-reference has to match the suffix string exactly before the drive drops into a working cabinet.
Where it does and does not sit against a sibling
The ABB ACS880-01-065A-5 is a same-class low-voltage drive, but it is a different generation in the ACS880 family and not a confirmed drop-in for an ACS800-DEMAG build — treat it as a comparison candidate on motor-drive selection, not as a verified replacement for this specific suffix string.
