ABB 3HAB8101-13 Inmotion Industrial Robot Servo Drive Rectifier Unit

ABB 3HAB8101-13 Inmotion Industrial Robot Servo Drive Rectifier Unit is a DSQC-346U rectifier module designed to power a single axis of an ABB industrial robot within an InMotion servo drive setup. This DC4 rectifier unit is typically mounted in ABB robot cabinets paired with an S4C+ controller and is intended to drive one orange-series servo motor from an InMotion servo drive. The 3HAB8101-13 assembly is commonly listed as the DSQC-346U rectifier for ABB IRB robots, aligning with configurations that include the DSQC-346U drive unit and its InMotion control stack. Market references show variants such as 3HAB8101-13/11A and 3HAB8101-13/11C, representing revision or region-specific versions of the same rectifier unit. Typical applications are automation cells where ABB robotic arms require reliable, axis-specific servo power, including material handling, pick-and-place, and precise positioning tasks in manufacturing environments that deploy ABB IRB robots and S4C+ controllers. As part of the InMotion drive family, this rectifier unit participates in the drive chain supporting the servo inverter to deliver controlled torque and speed for a single axis.
