FANUC A06B-6066-H004 Overview

Fanuc A06B6066H004

The Fanuc A06B6066H004 is a versatile and powerful 1-axis amplifier designed for precision control and operation of servo motors in industrial applications. This amplifier is specifically tailored for use with the C series servo amplifiers, providing compatibility and optimized performance. With a 200V input type (200V/230V) and a range of compatible motors, the A06B6066H004 offers a comprehensive solution for diverse automation and manufacturing needs.

Key Features

The A06B6066H004 amplifier is equipped with a Pulse Width Modulation (PWM) controller and a power controller. The PWM controller variants include A20802900-0610 (X1), A20802900-0620 (X1), and A20B-2900-0630 (X1). These controllers are essential for precise motor control, enabling smooth and accurate adjustments of motor speed and torque.

The power controller options for the A06B6066H004 include Al6B-1200-0911, Al6B-1200-0910, A20B-1004-0851, and A2OB-1004-0850. These power controllers play a crucial role in regulating and distributing the electrical power required for efficient motor operation.

Compatibility and Application

The A06B6066H004 is compatible with various motor types, including o-OSP, OS, 5s, lOS, 2OS/1500, OT/3000, 5-F/2000, 1 OT/2000, and OL. This wide compatibility allows the amplifier to be used across a range of machinery and automation setups, making it a versatile choice for different industrial environments.

Servo Amplifier State Indication

One of the standout features of the A06B6066H004 is its LED indicator system which provides valuable information about the amplifier's status. The LED indicators are located on the printed circuit boards of the amplifier, offering quick and easy detection of any potential issues. These indicators include:

  • "5V" (Green): Indicates control power is on.
  • "DRDY" (Green): Signals the availability of the PWM signal and readiness of the servo amplifier.
  • "HV" (Red): Indicates a high voltage alarm caused by the DC link voltage exceeding limits.
  • "HC" (Red): Indicates a high current alarm triggered by the excessive current in the DC link.
  • "LV" (Red): Signals a low voltage alarm, which occurs when the DC link voltage is too low or the regulator circuit malfunctions.
  • "DC" (Red): Indicates a discharge alarm, which is activated when the discharge circuit capacity is exceeded.
  • "OH" (Red): Signals an overheating alarm resulting from a normally closed thermostat contact opening.
  • "FAL" (Red): Indicates a fuse alarm, often related to dynamic brake activation or a fuse trip.

Maintenance and Protection

The A06B6066H004 amplifier incorporates protective measures to prevent malfunctions and ensure safe operation. For instance, overvoltage and overcurrent protection, as well as alarms for high voltage and high current conditions, contribute to the safety and longevity of the equipment.

In conclusion, the Fanuc A06B6066H004 1-axis amplifier stands as a robust and intelligent solution for controlling servo motors in industrial settings. With its advanced features, LED indicators, and protective mechanisms, this amplifier contributes to the efficiency, reliability, and safety of automation processes.
