    摘要: A positioning control system wherein variations in the robot coasting distance are substantially eliminated by stopping the command pulse signals simultaneously with a generation of the origin pulse signal from the incremental encoder. The deviation between the final robot position and the origin is minimized by driving the motor in its backward direction to back up the robot by an amount approximately equal to the coasting distance. The robot moving distance during the time period from the beginning of origin return operation (i.e., backup) to a generation of the first spike in the origin pulse signal after beginning backup to the above first stoppage of the robot is found. If the found distance is different from the coasting distance then this difference is handled as an error.In one aspect of the present invention, the number of spikes appearing in the output pulse signal from the incremental encoder can be easily increased as necessary to thereby improve the resolution power of the incremental encoder. Further, much more precise positioning control can be realized by synchronizing the output pulse signal of the incremental encoder with the clock signal of the microcomputer.

    摘要: A method and system for controlling pulse-driven actuators on multidimensional coordinates includes a cutting tool connected to the actuators of a machine tool. The cutting tool is controlled with a specified path and a specified velocity by controlling the output pulses of a multiplier. Data on the coordinates of a plurality of points including points A and B on the specified path and on the specified velocity F is received along with a command indicating an interpolation type. A linear interpolation is performed by a straight line between the point A and the point B, and the interpolated straight line is divided into minute lengths .DELTA.L and a minute length .DELTA.La correspondingly to a minute time .DELTA.T. .DELTA.T is changed by sending either a first control signal for keeping the specified velocity F corresponding to the minute length .DELTA.L or a second control signal for keeping the specified velocity F corresponding to the minute length .DELTA.La to a pulse oscillator for supplying pulses to the multiplier. If the selection of the control signals is appropriate, the cutting tool can keep the specified velocity F when it moves on either portion of .DELTA.L or .DELTA.La.

    摘要: A backup power-source module that controls a backup power source for supplying power from a battery charged by an AC input to an electronic device when the AC input is cut off. The backup power-source module includes a selection which generates a selection signal for selecting power supplied by a battery when the electronic device is kept in an electrified state until the electronic device is shifted to a power cutoff state and there is no AC input. I.E., the selection signal causes the power supplied by the battery to be selected only when the electronic device is kept in a power cutoff state and there is no AC input.
