ABB 3HAC5958-1 / 3HAC9328-1 / 3HAC050554-001 – Cable Unit Ax.1-3 | IRB 4400 / IRB 2400 Robot Platform
Engineering Background: The ABB IRB 4400 and IRB 2400 series are among ABB’s most widely deployed industrial robot platforms, used across automotive body-in-white, arc welding, material handling, and precision assembly lines worldwide. Maintaining signal and power integrity across axes 1–3 is critical to robot repeatability and uptime. The Cable Unit Ax.1-3 is the OEM-specified harness assembly that routes motor power, encoder feedback, and brake control signals through the lower arm structure.
Product Positioning: Konmask.com supplies this cable unit as a direct OEM-equivalent replacement, sourced from verified ABB-authorized channels. Each unit is traceable to ABB part numbers 3HAC5958-1 (primary), 3HAC9328-1 (alternate revision), and 3HAC050554-001 (latest revision), ensuring cross-compatibility across IRB 4400 and IRB 2400 build generations. Procurement engineers can specify any of the three part numbers interchangeably for MRO and capital-spares planning.

Engineering Advantages
- OEM Dimensional Conformance: Exact routing length, connector positions, and strain-relief geometry match ABB factory specification — no field modification required.
- Multi-Revision Coverage: Three interchangeable part numbers (3HAC5958-1, 3HAC9328-1, 3HAC050554-001) cover the full production run of IRB 4400 and IRB 2400, eliminating cross-reference risk.
- Signal Integrity: Shielded conductors and OEM-grade insulation maintain encoder signal fidelity at rated robot speeds, preserving TCP accuracy.
- Plug-and-Play Replacement: No re-parameterization or software changes required after installation — robot resumes operation immediately after cable swap and mastering verification.
- Traceable Supply Chain: Units sourced from ABB-authorized distributors with full lot traceability for quality audit compliance.
System Architecture & Signal Flow
The Cable Unit Ax.1-3 originates at the robot base junction box (J1 axis drive cabinet interface) and routes through the S1 swivel and lower arm casting to the J3 axis gearbox. It carries:
- Axis 1 (J1): Motor phase power (U/V/W) + resolver feedback + brake
- Axis 2 (J2): Motor phase power (U/V/W) + resolver feedback + brake
- Axis 3 (J3): Motor phase power (U/V/W) + resolver feedback + brake
The upper arm cable unit (Ax.4-6) interfaces at the J3 output flange — ensure both harnesses are inspected simultaneously during preventive maintenance to avoid repeat downtime.
Sourcing & Quality Verification
- All units inspected for connector integrity, insulation continuity, and shield termination before dispatch.
- Packaging includes ABB OEM part number label for incoming inspection and ERP receiving verification.
- Lot documentation available on request for ISO 9001 / IATF 16949 audit trails.
- Stock held in ESD-safe, climate-controlled warehouse to preserve connector and insulation integrity.
Procurement Process
- Confirm robot serial number and build date to verify part number applicability (3HAC5958-1 / 3HAC9328-1 / 3HAC050554-001 are interchangeable across all IRB 4400 and IRB 2400 builds).
- Submit RFQ or place order directly via Konmask.com product page.
- Receive order confirmation with estimated lead time and tracking.
- Incoming inspection: verify OEM part number label, connector count, and cable length against robot BOM.
- Installation per ABB Product Manual — IRB 4400 / IRB 2400, Cable Replacement section.
- Post-installation: perform axis mastering and test run at reduced speed before resuming production.
Technical FAQ
Q: Are 3HAC5958-1, 3HAC9328-1, and 3HAC050554-001 fully interchangeable?
A: Yes. These are successive ABB revision numbers for the same cable unit assembly. All three fit all IRB 4400 and IRB 2400 lower arm configurations without modification.
Q: Does this cable unit cover axes 4–6?
A: No. This unit covers axes 1–3 (lower arm). For axes 4–6 (upper arm/wrist), a separate cable unit is required — contact Konmask.com for the matching upper arm harness part number.
Q: What is the recommended replacement interval?
A: ABB recommends inspection at every 12,000-hour service interval. Replace immediately if insulation cracking, connector corrosion, or intermittent encoder faults are observed.
Q: Can I order in bulk for a capital spares program?
A: Yes. Contact [email protected] for volume pricing, blanket order arrangements, and consignment stock options.
Q: Is expedited shipping available?
A: Yes. Express air freight options are available at checkout or by contacting our team directly.
