ABB RV-80N-129 3HAC043074-001 is a compact wrist reduction gear for the IRB 6700 robot. It reduces motor speed at the wrist and transfers torque to the associated wrist axis through the RV-80N 129-ratio execution.

Because ABB RV-80N-129 3HAC043074-001 works near the tool flange, its alignment affects wrist motion, sealing and the calibrated tool-center-point relationship. Input coupling, output interface and mounting faces must remain clean and concentric during assembly.

Service on ABB RV-80N-129 3HAC043074-001 requires the wrist and tooling load to be supported. After installation, calibration and slow compound wrist movement are used to detect binding, noise, leakage or direction error before normal robot motion.
