    摘要： A method and apparatus for controlling, in power failure, such a machine that a workpiece and a tool are required to be always synchronized in their motion. The method and apparatus allow the tool and workpiece to move back and stop at a safe area without causing any damage to them when the main power source is lost. When a power failure has happened in the middle of a synchronous operation of the motors (S1), a power regeneration function is first disabled (S2). Then a braking control command is issued so as to decelerate the tool drive motor and the workpiece drive motor while maintaining their synchronization (S3). In this step S3, the deceleration rate is controlled so that the motors regenerates energy just enough for driving the tool feed motor. The tool retracts back to an area where it is no longer engaged with the workpiece, by driving the tool feed motor with the regenerative energy produced by the deceleration of the tool drive motor and the workpiece drive motor (S4).

    摘要： In a machine to be operated such that tools and a work are always brought into synchronism with each other, method and device for controlling at the time of power failure adapted to retract tools to a safe area without breaking the tools and a work at the time of power failure. When a power fails during synchronous operation (S1), a power supply regenerating operation in a power supply regenerating power circuit is halted (S2), sending to a motor for tools and a motor for a work, respectively, braking commands for controlling them to a reduced speed which is good enough to generate regenerating energy needed not only to keep a predetermined synchronism therebetween but also to drive a motor for moving tool shafts (S3), and driving the motor for moving tool shafts with regenerating energy produced through the speed reducing operation of the motor for tools and the motor for a work so as to retract the tools to an area where they do no interfere with the work (S4).
