The newer ACH580-01-014A-4 platform at 6.80 kgs is a generation shift, not a verified substitute — the mechanical footprint and the control block architecture move with it, so a swap is a re-engineering task rather than a panel drop-in. ## Sourcing posture","metaTitle":"ABB ACS550-U1-046A-2+B055+L512 Motor Drive, 9.07 kg","metaDescription":"ABB ACS550 series Motor Drive, order code ACS550-U1-046A-2+B055+L512, listed at 9.07 kgs.
