ACS 550 Drive
Voted best answer
As no particular drive model is mentioned, I tried to find ACS 550-01/U1/U2 – PC/PD manuals from ABB solutions bank at links below, please note that AKS is web forum for sharing knowledge/information related to control systems for process automation. Hence would be difficult to get answers/information related to drives from AKS community. Recommended to check at ABB solutions bank, abb library or with ABB local contacts.
