AC drives and DC drives
Technical records for legacy ABB industrial drives, beginning with the ACS800 AC drive and DCS800 DC drive families: board functions, fault routing, interface paths and controlled diagnostic workflows.
Available series
ACS800 coverage starts where repair decisions become expensive: PPCC communication between control and inverter interface electronics, short-circuit trips around the power stage, and AGDR-linked IGBT driver/module identification for larger frames.
DCS800 coverage organizes the D1–D7 converter platform around the control, power-supply, measurement and field-exciter relationships that technicians need when an older DC drive cannot be returned to service safely.
