Technical Specifications

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Solving the Discontinued Hardware Crisis

The ABB IRB 6600 was a workhorse platform deployed extensively in automotive, foundry, and heavy-manufacturing environments from the early 2000s onward. ABB has since moved its active portfolio to the IRB 6700 and IRB 6790 families. Spare parts for the IRB 6600 — particularly axis servo motors — are no longer manufactured and are not available through standard ABB distribution channels.

Sourcing a verified 3HAC12732-9 from DriveKNMS eliminates that cascade. The robot stays in service. The cell stays qualified. The capital expenditure is deferred — often by five to ten years — at a fraction of the cost of a platform migration.

Condition & Reliability Assurance

Obsolete servo motors present specific failure risks that differ from standard wear-and-tear on active production parts. Our 5-step QA process is designed around those risks:

Step 1 – Electrolytic Capacitor Inspection: Long-storage servo drives and motors are susceptible to capacitor degradation. Each unit is inspected for capacitor bulging, leakage, and ESR deviation before dispatch.

Step 2 – Encoder & Feedback Integrity Check: The resolver or encoder assembly is tested for signal integrity. A corrupted feedback signal causes axis faults that are frequently misdiagnosed as controller issues.

Step 4 – Insulation Resistance Test: Winding insulation is tested to confirm no moisture ingress or insulation breakdown — a critical check for motors that have been in warehouse storage.

Step 5 – Functional Rotation Test (where applicable): Units are rotated under no-load conditions to confirm bearing smoothness and absence of mechanical binding before packaging.

Key Features for System Maintenance

The 3HAC12732-9 is a direct mechanical and electrical replacement for the original axis motor in the IRB 6600. There is no firmware modification required on the IRC5 or S4C+ controller. The robot's existing axis calibration data remains valid — no re-mastering is required beyond the standard post-motor-swap calibration procedure documented in ABB's IRB 6600 product manual.

This means your maintenance team can execute the swap using existing skills and tooling. There is no requirement to engage ABB field service for a controller reconfiguration, no need to re-qualify the robot's safety zones, and no disruption to the cell's existing program logic. The total engineering cost of the repair is limited to the motor cost plus standard maintenance labor — a fraction of what a platform migration would demand.

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.
