ABB DASD147 3ASC25H280 Motion Controller

ABB DASD147 3ASC25H280 Motion Controller / Servo Drive Unit

Product Description

ABB DASD147, part number 3ASC25H280, is a high-power servo drive & motion control unit within ABB ASTAT series, end-of-life by OEM. It is a DC servo drive integrating power amplifier, closed-loop control for position, speed and current, for DC servo motors with high-precision torque, speed and position regulation. It includes built-in comprehensive diagnostics and protection against overcurrent, overvoltage, overtemperature and encoder failure. It accepts encoder feedback and is designed for heavy-duty multi-axis synchronisation such as metal rolling mills, paper machines and wire lines. Cabinet wall-mounted, it serves as the core drive unit for legacy heavy industrial transmission systems.
