A06B-6130-H404

This unit is an external regenerative braking resistor, applied to 200V class FANUC βi series servo amplifiers. It dissipates regenerative energy generated during motor deceleration and prevents DC bus overvoltage fault.

Description

1. General Description

The A06B-6130-H404 is a heavy‑duty separate regenerative resistor designed for use with 200V‑class FANUC βiSV / βiSVM servo amplifiers. It absorbs and dissipates regenerative energy generated during motor deceleration, preventing DC‑bus overvoltage alarms (e.g., ALM 430) in high‑inertia, vertical‑axis, or frequent‑stop applications.

6. Features

  • High power dissipation for heavy regenerative loads.

  • Finned aluminum case for improved cooling efficiency.

  • Direct plug‑in to standard servo amplifier resistor ports.

  • Protects drives from overvoltage faults during heavy deceleration.

7. Installation Instructions

  • Mount vertically inside the electrical cabinet.

  • Maintain minimum 50 mm clearance on all sides for ventilation.

  • Connect only to the designated resistor connector (CX23/CZ6) on the servo amplifier.

  • Ensure all AC and DC power is disconnected before wiring.

8. Safety Precautions

  • Surface temperature can exceed 100 °C during/after operation—do not touch.

  • Use only genuine FANUC A06B‑6130‑H404 to ensure safety and compatibility.

  • Incorrect resistance or undersized power rating may cause overheating or drive damage.
