ABB IRB6700 Series Technical Notes

The ABB IRB6700 is a large industrial robot series engineered for heavy-duty applications including automotive body-in-white assembly, foundry operations, chemical plant material handling, and offshore energy sector automation. With payload capacities ranging from 150 kg to 300 kg and reaches from 2.6 m to 3.2 m, the IRB6700 family holds a dominant installed base across global heavy industry — including petrochemical refineries, nuclear facility maintenance cells, and large-scale press-tending lines. Its modular drive and control architecture is built on ABB's IRC5 controller platform, making spare parts availability a critical operational factor for facilities running multi-shift production schedules.

The Evolution of IRB6700 Architecture

The IRB6700 was introduced in 2013 as the successor to the IRB6640 and IRB6650 families, consolidating multiple payload/reach variants under a unified mechanical platform. The IRC5 controller — which governs all IRB6700 variants — uses a distributed drive module architecture (DSQC series boards) communicating over an internal DeviceNet/PROFIBUS backbone. Early production units (pre-2016) used the DSQC522 and DSQC508 I/O boards; post-2016 revisions introduced updated firmware-compatible replacements. The servo motor assemblies, identified by 3HAC-prefixed part numbers, are axis-specific and not interchangeable across payload classes without recalibration. The 3HNP-prefixed components cover mechanical sub-assemblies including gearbox seals, bearing kits, and cable harnesses. As the IRB6700 series has entered its mature lifecycle phase (10+ years in production), long-term maintenance support — including sourcing of discontinued board revisions — is now a primary procurement concern for end users.
