FANUC A06B-6077-H002

The A06B-6077-H002 is a power failure backup module. While this Fanuc CNC automation LTD Yamanashi 401-0597, discontinued by manufacturers, originally manufactured in Japan, and is still available from distributors like MRO Electric and Supply Inc. The A06B-6077-H002 is useful in the instance that the primary supply of power fails, malfunctions, or loses connection. The A06B-6077-H002 utilizes the kinetic energy found in the spindle motor to supply power to the controls to the servo motors, in the case of a power shortage, to retract the machine tools from their current working function on a specific machine piece or simply stop the movement of pieces to prevent a crash.

When complete power failures occur, or even if a simple power bump occurs, this can be the cause of major damages to specific machinery and possibly the whole machinery environment.FANUC has been sure to develop the A06B-6077-H002 to provide a backup power supply that can support the machine during any minor issues which might prevent the main power supply from reaching the necessary modules to keep the larger machine running. In case of minor or short-term power failures (less than 100 ms), the option is available for each user to customize the guidelines for how the machine will respond and react to a shortage or loss in power.

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. There are various faults that the A06B-6077-H002 can experience that are important to be aware of. When the LED display is not working the power module likely experienced an internal short circuit. If the engine stutters, then the driver amplifier control and/or the transistor modules may have failed. When the power supply module only functions after warming up, the internal power supply unit or the system control board is likely to have malfunctioned. One final common fault that can cause malfunction for the A06B-6077-H002 is when the system control board is not working, this means that there is likely failure in the communication of the system with the CNC. These faults can likely be identified and remedied based on the results of testing to 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.
