Brief Product Description

3HAC14940‑1 is an OEM manipulator cable harness dedicated for ABB IRB7600 and IRB6650 series industrial robots, covering axes 1‑4 internal wiring of robot arm. This pre‑assembled wiring assembly transmits motor power and encoder feedback signals between robot base and joint units. Built with high‑flexibility, abrasion‑resistant cable material, it withstands continuous bending motion of robotic joints under heavy‑duty workshop conditions, guaranteeing stable signal and power transmission for robot coordinated movement, widely used as replacement spare part for robot maintenance and repair.

Core Product Functions

• Integrated power supply transmission for axes 1‑4 joint servo motors of IRB7600 / IRB6650 robot arm
• Real‑time encoder feedback signal transmission for joint position and speed monitoring
• Complete pre‑terminated harness with original matching connectors for direct plug‑and‑play installation
• High‑flex cyclic bending resistant cable design adapting to frequent robot joint rotation motion
• Shielded wiring structure to suppress electromagnetic interference in noisy factory environments
• Integrates multiple signal loops inside one harness bundle, simplifies robot internal wiring layout
• Maintains stable communication between robot manipulator and IRC5 controller system
• OEM‑level mechanical dimension matching, fits original robot internal routing path perfectly
• Reduces unexpected downtime caused by aging or broken original robot internal cables

Application Scenarios

• Heavy‑duty ABB IRB7600 and IRB6650 robot arm axes 1‑4 internal wiring replacement
• Automotive manufacturing production line robot maintenance and overhaul projects
• Metal processing, foundry and heavy handling robotic workstation repair
• Warehouse logistics large payload robot system cable renewal
• Retrofit service for aged ABB IRC5 controlled heavy robot installations
• Spare manipulator harness stocking for robot system integrators and maintenance vendors

FAQ (Frequently Asked Questions)

• Q: Robot reports motor or encoder fault after harness replacement?
  A: Check connector full insertion, locking status, pin damage, wrong routing causing cable tension or twisting during joint movement.
• Q: Alarm occurs intermittently only when robot moves to certain joint angles?
  A: It usually indicates local cable inner conductor breakage caused by cyclic bending; inspect harness wear and stress points inside robot arm.
• Q: Can 3HAC14940‑1 be hot‑replaced while robot power remains on?
  A: Hot replacement is forbidden. Power off robot controller and release residual voltage before harness disassembly to avoid servo drive damage.
• Q: Can this harness fit other robot models besides IRB7600 and IRB6650?
  A: It is exclusively designed for axes 1‑4 of IRB7600 / IRB6650; mechanical layout and connector definition differ for other robot series, cross‑model use is not allowed.
• Q: Is original new 3HAC14940‑1 still available for new robot projects?
  A: Original OEM production is limited. Most available stock are surplus, tested or refurbished units for existing robot maintenance purpose.
