ABB DSQC346U 3HAB8101-13 07B Servo Drive Unit

ABB DSQC346U drive unit, 3HAB8101-13 (07B), is a two-axis servo drive module designed for ABB S4, S4C, and S4C+ robots. This DSQC 346U GU drive unit houses the servo drive electronics that control two ABB orange-series servo axes, delivering precise position, velocity, and torque commands within the robot’s motion system. The unit measures 174.6 mm (6.875 in) long, 123.8 mm (4.875 in) wide, and 368.3 mm (14.5 in) tall, reflecting a compact footprint suitable for integration in ABB controller cabinets. The 3HAB8101-13 designation identifies the ABB design, with the 07B variant representing a specific configuration within the DSQC346U family. As a drive module in ABB installations, it is intended to drive two servo axes and works in concert with the robot controller to enable reliable, synchronized motion in industrial automation tasks. Typical applications include robotic arms and automation cells where precise two-axis motion is required, such as coordinated pick-and-place, assembly, or material handling within ABB-based production lines.
