ACS880 Offshore Control Program Technical Description

This document describes the ABB ACS880 Offshore Control Program (+N5800) for electrically driven marine offshore winches and hoists, featuring integrated Active Heave Compensation (AHC), tug escort/push modes, and built-in rope force and length measurement. It covers the operating principle of always-active electric winch motors, electrical braking options (dynamic and regenerative), and the compact, cost-effective design with control algorithms embedded directly in the drive hardware.
