ABB IRB6700 Series Technical Notes

The ABB IRB6700 is a heavy-duty industrial robot series engineered for high-payload applications in continuous-process industries including petrochemical refining, nuclear facility maintenance, automotive body-in-white assembly, and large-scale metal fabrication. With payload capacities ranging from 150 kg to 300 kg and reaches from 2.6 m to 3.2 m, the IRB6700 occupies a dominant position in the global heavy industrial robot installed base. Its servo drive architecture—built around ABB's IRC5 controller platform—relies on a distributed axis computer and resolver-based feedback system, making individual servo motor assemblies such as the 3HNA015149-001, 3HAB8101-2/04B, and 3HAC048228-001 critical long-lifecycle spare components for plant maintenance teams worldwide.

The Evolution of IRB6700 Architecture

The IRB6700 was introduced by ABB Robotics in 2013 as a direct successor to the IRB6640 and IRB6650 platforms. The architectural transition brought a redesigned wrist assembly, a new generation of servo motor housings with improved IP67 sealing, and a shift from the M2004 controller to the IRC5 single-cabinet controller with integrated drive modules. The resolver interface board (RID) subsystem—represented by components such as the RID-02 board (part number 3HNA015149-001)—handles analog resolver signal conditioning for each robot axis, translating position feedback into digital data consumed by the axis computer. Early IRB6700 units (pre-2016) used the 3HAB8101-2 series motor variants; post-2018 production runs introduced updated winding specifications reflected in the 3HAC048228-001 motor assembly. Compatibility between these generations requires careful cross-referencing of axis number, payload variant, and firmware revision of the IRC5 controller. Plants operating mixed fleets of IRB6640 and IRB6700 robots must maintain separate spare pools, as the servo motor connectors and resolver pinouts are not interchangeable between generations.

Quality Control for the IRB6700 Range

IRB6700 servo motor assemblies and resolver interface boards require specialized test procedures that differ from standard AC servo motor bench testing. DriveKNMS applies the following verification protocol to all IRB6700 components prior to shipment:

• Resolver signal integrity test: Each RID board (e.g., 3HNA015149-001) is tested under simulated 6-axis resolver load using ABB-compatible signal generators, verifying SIN/COS amplitude balance and phase accuracy to within ±0.5%.
• Winding resistance and insulation test: All servo motor windings are measured for phase-to-phase resistance balance and insulation resistance (minimum 100 MΩ at 500VDC) per IEC 60034-1 standards.
• Backplane bus communication verification: IRC5 drive modules are tested on a live IRC5 test bench to confirm SERCOS III communication handshake and axis enable sequencing.
• Mechanical inspection: Encoder housings, shaft seals, and connector bodies are inspected for impact damage, corrosion, and seal integrity before functional testing begins.
• Burn-in cycle: Servo motors are run under no-load conditions for a minimum of 2 hours to confirm thermal stability and bearing noise levels within ABB specification limits.
