The FANUC A06B-6077-H002 is a power failure backup module designed to support CNC machines during power interruptions or supply instability. Originally manufactured in Japan by FANUC CNC Automation LTD (Yamanashi 401-0597), the A06B-6077-H002 has been discontinued by the manufacturer but remains available through distributors such as MRO Electric and Supply. This module plays an important role in helping protect CNC equipment when the primary power supply fails, malfunctions, or temporarily loses connection.
The FANUC A06B-6077-H002 supports CNC machines during complete power failures, power malfunctions, and brief power interruptions. When the primary power supply is lost or temporarily disrupted, the A06B-6077-H002 provides short-term backup power to help maintain controlled machine behavior and reduce the risk of equipment damage.
During a power shortage, the A06B-6077-H002 utilizes kinetic energy generated by the spindle motor to temporarily supply power to CNC controls and servo systems. This allows the machine to retract tooling from the workpiece or safely stop motion, helping prevent crashes or unintended machine movement. Even minor power disturbances, such as brief power bumps, can cause serious issues in CNC environments. For short-term power failures (typically less than 100 ms), users may configure how the CNC system responds to a loss of power, allowing customized shutdown or recovery behavior based on application requirements.
The rated voltage for the A06B-6077-H002 is 283-325 volts, the manual number is B-65162, and the standards are DIN VDE 0160. The A06B-6077-H002 power supply module is usually fitted with an alpha spindle and servo module to accommodate a smaller FANUC alpha motor.
The A06B-6077-H002 power failure backup module may experience several fault conditions that are important to recognize during troubleshooting. If the LED display is not functioning, the A06B-6077-H002 may have experienced an internal short circuit. If the machine engine stutters, the driver amplifier control or the transistor modules may have
failed. If the A06B-6077-H002 only operates after warming up, this may indicate a malfunction in the internal power supply unit or the system control board. Another common fault occurs when the system control board is not functioning properly, which can result in a communication failure between the A06B-6077-H002 and the CNC system. These fault conditions can often be identified and addressed based on diagnostic testing of the power
failure backup module.
There are start-up procedures for the FANUC system which include specific things about the A06B-6077-H002. Such things as power-failure backup modules and other details that the programmer and controller need to be made aware of. Two of these specifications are the wiring board specification for the A06B-6077-H002 which are A16-2203-0510, and the printed circuit board specifications for the A06B-6077-H002, which are A20B-2003-0020.
