    摘要: Provided is a motor control system of a numerical controller that can instruct a plurality of motors and display data on a display device by means of a single serial bus. An amplifier which controls the motor drives the motor based on a motor command received from the numerical controller via the serial bus. The display device display data on a screen based on display data received from the numerical controller via the serial bus.

    摘要: An arithmetic unit for correcting a detection output of a detector for a mechanical error of the detector in accordance with a predetermined input/output characteristic (straight line) is provided. When a digital output of the detector exceeds an upper limit value stored in a main memory, the digital output becomes a new upper limit value. From a virtual line which passes through the new upper limit value and which is parallel to the straight line, a new lower limit value is obtained. A corrected operation output is obtained in accordance with a new input/output characteristic of the detector based on the new upper limit value and the new lower limit value. Thus, the correction accuracy is improved.

    摘要: A drive control system for supplying a drive voltage to a DC servo motor. The drive control system includes a position detector for detecting a rotational position of the DC servo motor, and a controller which switches the drive mode of the DC servo motor from DC drive to PWM drive when a detected position value obtained by the position detector is within a predetermined amount of a value corresponding to a target stop position.

    摘要: A personal computer (PC) and a programmable controller are used to automatically reposition the turn bars and compensation rollers used in a folder for a web printing press. By providing linear transducers for each of the turn bars and compensation rollers disposed at each level of the folder, analog information as to the actual position of each is provided to the programmable controller. The PC provides digital information to the programmable controller as to the desired position and an error signal is computed for controlling the operation of the drive motors so as to reduce the error signal to zero. When setting up the folder to run a new job, the turn bar settings and compensation roller positions are manually accomplished, but upon command, the settings for that job may be stored in the memory of the PC for use the next time that particular job is to be run.
