ABB DSQC346U 3HAB8101-13 05B Servo Drive Module

ABB DSQC346U 3HAB8101-13/05B Servo Drive Module is the DSQC346U drive unit (GU) designed for ABB S4C/S4C+ robot systems, published as part of the 3HAB8101-13 family. This drive unit provides the servo amplification and control interface needed to drive a single ABB servo motor in automated applications, with the catalog description explicitly listed as Drive unit GU. The component’s physical footprint is 6.875 inches long by 4.875 inches wide by 14.5 inches high, size that fits typical control cabinet installations. Catalog data identifies the module under the Drive unit GU designation, with an ordering code of CS-4003 and a Replacement Product ID marked as NEW, signaling its role as a direct replacement within the DSQC346U lineup. In various repair and parts catalogs, the 3HAB8101-13 variant is associated with DSQC346U servo drive functionality for ABB robotic systems, and several listings reference compatibility with ABB servo motors (including those in the “orange series”) used in S4C/S4C+ installations. As a DSQC346U drive unit, it serves as the motion control component that interfaces between the robot controller and the servo motor, enabling precise control of speed and torque for industrial automation tasks in manufacturing, packaging, and assembly environments.
