Technical Specifications

Note: Electrical parameters (voltage, current rating, encoder resolution) are axis-position dependent within the IRB6700 platform. Confirm your axis number before ordering. We do not publish unverified specifications.

Solving the Discontinued Hardware Crisis

The ABB IRB6700 was introduced as a high-payload, long-reach robot designed for demanding industrial environments. Many facilities installed these units in the early-to-mid 2010s as part of major capital investment programs. A decade-plus of continuous operation means the mechanical and electrical wear on axis motors is real — and ABB's standard supply chain for legacy drive components has contracted significantly.

The 3HAC061315-003 motor is not a commodity item. It is a precision-matched component tied to the IRB6700's axis geometry, gear ratio, and IRC5 controller feedback loop. Substituting an unverified motor risks encoder mismatch, torque calibration errors, and — in worst cases — axis collision events that damage the gearbox, the end-effector, and the workpiece simultaneously.

How to Extend Your IRB6700 Asset Life by 5–10 Years

Facilities that manage legacy robot fleets successfully share a common discipline: they treat critical spare parts as capital inventory, not as reactive purchases. For the IRB6700 platform specifically, the following strategy has proven effective in extending operational life well beyond the manufacturer's implied support window:

1. Identify your highest-risk axes. On IRB6700 configurations, axes 1, 2, and 3 carry the highest mechanical load and therefore the highest motor wear rate. Prioritize spare motor procurement for these positions first.

2. Maintain a minimum one-unit buffer per robot cell. A single unplanned motor failure with no spare on hand can idle a cell for 4–12 weeks while sourcing is arranged through the secondary market. One unit in storage eliminates that exposure entirely.

4. Pair motor replacement with gearbox inspection. A failed motor that has been running in a degraded state often transmits abnormal loads to the adjacent gearbox. Replacing the motor without inspecting the gearbox is an incomplete repair.

5. Document firmware and calibration data before any motor swap. The IRC5 controller stores axis-specific calibration offsets. Capturing this data before removal ensures the replacement motor can be brought online without a full re-calibration cycle, saving 4–8 hours of engineering time per event.

This approach — disciplined spare parts inventory combined with condition-based maintenance — is the lowest-cost path to keeping IRB6700 assets productive through the end of their mechanical service life.

Condition & Reliability Assurance

Every 3HAC061315-003 unit that leaves our facility has passed a structured 5-step inspection protocol developed specifically for discontinued servo motor components:

Step 1 – Electrolytic Capacitor Assessment: Internal capacitors are inspected for bulging, leakage, and ESR degradation. Capacitor failure is the leading cause of drive electronics failure in motors stored beyond five years.

Step 2 – Firmware Version Verification: Where applicable, encoder firmware and motor parameter files are verified against known-good IRB6700 axis configurations.

Step 3 – Pin and Connector Corrosion Inspection: All electrical connectors are inspected under magnification for oxidation, pin deformation, and contact resistance anomalies. Corroded pins are the most common cause of intermittent encoder faults post-installation.

Step 4 – Mechanical Rotation and Bearing Check: The motor shaft is rotated manually and under low-speed power to detect bearing roughness, axial play, and abnormal resistance.

Step 5 – Final Functional Test and Documentation: Each unit is tested under load simulation where equipment permits, and a condition report is issued with the shipment.

Key Features for System Maintenance

Drop-in replacement: The 3HAC061315-003 is a direct mechanical and electrical replacement for the original axis motor position in the IRB6700. No bracket modification, no wiring adaptation, no controller reconfiguration is required beyond standard axis calibration.

No re-programming required: The IRC5 controller recognizes the motor through its existing axis configuration. Installation does not trigger a software migration or require ABB field service intervention in standard replacement scenarios.

Avoids engineering reconstruction costs: Replacing this motor with a verified OEM-equivalent part costs a fraction of the engineering hours required to adapt a non-standard motor or to re-integrate a replacement robot model into an existing cell layout, fixture set, and safety zone configuration.

Q: How do I confirm the unit is genuine ABB and not a counterfeit?
A: All units are sourced through documented industrial channels. We provide the original ABB part label, serial number, and our inspection report with every shipment. We do not sell unmarked or relabeled components.

Q: Can you source other IRB6700 spare parts?
A: Yes. DriveKNMS specializes in hard-to-find ABB robotics components across the IRB6700, IRB6600, and IRB7600 platforms, as well as IRC5 controller modules. Contact us with your full part number list.
