                  • Model: DSQC 346A

                  • Part Number: 3HAB8101‑5/04A (also referred to as 3HAB8101‑5)

                  • Type: Servo Drive Unit, used to drive servo motors in motion control and feedback control systems.

                  • Weight: Approx. 3.2 kg

                  • Country of Origin: Ireland

                  • Application: Widely used in industrial robots / automation equipment as a dedicated drive module.

                  • Note: While full electrical specifications (rated voltage, current, output power) are not fully publicly available, the unit aligns with ABB’s servo drive series standards.

                  Advantages & Features

                  • High reliability: Designed for industrial-grade environments in ABB’s drive ecosystem.

                  • Strong brand compatibility: Tailored for ABB servo systems, facilitating replacement, maintenance, or expansion in existing systems.

                  • Moderate size & weight: Approx. 3.2 kg, making installation easier compared to larger units.

                  • Availability of spares: Although an older model, units or compatible variants remain found in the market.

                  • Suitable for dynamic motion control: Supports high response, high precision motion control tasks suitable for robotics, assembly, and machining systems.

                  Application Areas

                  • Industrial robots: As the servo drive unit in the robot’s drive/control system.

                  • Automated assembly/production lines: Driving servo motors for precise positioning, load handling, conveyors.

                  • CNC / machining equipment: Used for high-speed, high-precision motion control axes.

                  • Packaging / inspection systems: Where fast response and repeatable positioning accuracy are required.

                  • Maintenance and spare‑replacement for legacy ABB servo systems: Especially relevant where older ABB “InMotion” or servo platforms are still in use.

                  Precautions

                   

                  • When purchasing, ensure exact match of the model (DSQC 346A) and part number (3HAB8101‑5/04A) to guarantee system compatibility.

                  • During installation or replacement, power down, apply ESD protection, and verify cooling/ventilation.

                  • The servo drive works in conjunction with servo motor, encoder, feedback loops—when replacing the drive, recommend checking motor, wiring, feedback devices are in good condition.

                  • As an older model, when planning future upgrades or expansions, assess potential limitations in communications or interface compatibility.

                  • Storage and operating environment should avoid high temperature/humidity, strong vibration or corrosive atmospheres to assure longevity.

                  • For used or refurbished units, request test results, runtime hours, repair history, and check vendor’s return/exchange policy.
