Description

3HAC026611-001: Product Overview
The 3HAC026611-001 is an industrial robotic controller within ABB’s DSQC639 series, designed for deployment in automated manufacturing cells to serve as the central processing unit for robotic systems. Its role is to act as the brain of articulated robots (e.g., ABB IRB series), positioned in control cabinets to execute motion trajectories, coordinate multi-axis synchronization, and manage data exchange with field devices (sensors, drives, HMIs). In applications like welding, assembly, and material handling, it ensures precise positioning (±0.02mm repeatability) and dynamic response to process variations.
Functionally, the controller processes encoder feedback from robot joints, calculates inverse kinematics for path planning, and generates pulse-width modulated (PWM) signals to servo drives. It handles both cyclic tasks (real-time motion updates, 1-4ms cycle time) and acyclic tasks (diagnostics, recipe management, SCADA integration). As part of the DSQC639 platform, it leverages modular expandability, compatibility with ABB RobotStudio simulation software, and native integration with ABB’s safety-rated systems (e.g., SafeMove). Benefits include reduced integration time via preconfigured robot profiles, scalable I/O for custom tooling, and compliance with ISO 13849 safety standards.

Core Features & Customer Value​
Modular architecture for scalability: The controller’s modular design allows engineers to add I/O modules (e.g., analog input cards for force sensors) or communication gateways (e.g., PROFINET for vision systems) without replacing the base unit. For customers, this adapts to evolving production needs—such as upgrading a pick-and-place robot to include a camera for quality inspection—while minimizing upfront hardware costs.
High-performance motion control: The multi-core processor and real-time operating system enable precise trajectory tracking (e.g., circular interpolation for welding seams) and dynamic speed adjustment. In automotive body shops, this ensures consistent weld quality across 10+ robots, reducing rework. The 1-4ms cycle time supports high-speed applications like electronic component placement, where microsecond delays impact throughput.
Integrated safety and compliance: Built-in STO and collision detection functions eliminate the need for external safety relays, cutting panel space by 20%. Compliance with ISO 13849 PL d ensures alignment with OSHA and EU machinery directives, simplifying regulatory audits. For example, in collaborative robot cells, the controller limits joint torque to <150N, protecting human operators.
Remote diagnostics and maintenance: Ethernet-based remote access allows engineers to monitor robot performance (e.g., axis deviations, motor temperatures) and update firmware without physical access. This reduces downtime during unplanned stops—critical in 24/7 facilities like semiconductor fabs, where hourly output losses are costly.

Typical Applications​
In an automotive assembly plant’s welding line, the controller manages an IRB 6700 robot arm, coordinating 6-axis motion with part positioning fixtures. It exchanges weld schedules (via PROFINET) with the plant’s MES and logs joint currents to predict gearbox wear, enabling proactive maintenance.
At an electronics manufacturer, it controls a SCARA robot for surface-mount device (SMD) placement. The 64 AI channels read vision system coordinates (for component alignment), while 128 DO channels activate vacuum nozzles. Cycle times of 0.3 seconds per component are maintained via the 1.2 GHz processor’s fast path calculations.
In a pharmaceutical packaging line, the controller integrates a delta robot with a checkweigher (via DeviceNet). It adjusts pick rates based on weight feedback, ensuring 100% fill accuracy, and triggers rejection mechanisms for underweight packages—all while meeting FDA 21 CFR Part 11 data logging requirements.
