What the order code actually buys
The ABB ACS800-01-0135-3+P901 is a wall-mount low-voltage AC drive from the ACS800-01 frame, carrying the +P901 application macro suffix on the order string, and sits in the ABB Motor Drives line under Drives (ACS800-01-0135-3+P901). Handling weight is 30.39 kg; two-person lift and verify the panel mounting plate rating before mounting.
Where it sits in the ABB drive family
Three ABB family members are on the same sourcing desk — ACS880-01-065A-5 at 23.13 kg, ACS580-01-078A-4 at 28.58 kg, and ACS550-U1-072A-4+B055+L512 at 34.02 kg — but they are different generations (ACS880, ACS580, ACS550) of the same wall-mount low-voltage drive class, not drop-in alternates for the ACS800-01 frame; the panel specified around the ACS880 will not accept this drive without a mechanical and wiring-line review.
Commissioning-side anchors
The +P901 suffix on the ACS800-01 string is the application macro to verify on first power-up — macros change the I/O map and the default ramp/limit set, so the SAT checklist should open with a parameter dump confirming the macro before any motor is connected.
