    摘要: A gate operator with an extensible actuating arm adapted for light to moderate gate passing traffic. The operator comprises a small drive unit, such as an electric motor drive, and a rotatable drive shaft, such as a worm shaft driven through operation of the motor. An extensible shaft or so-called ball race shaft, cooperates with the rotatable shaft and extends inwardly or outwardly in response to rotation of the rotatable shaft. A microprocessor operated control circuit is used with or forms part of the operator, and measures a number of counts generated by magnetic elements rotatable with the worm shaft, and which are equivalent to distance units of measurement. In this way, the distance on the opening and closing movement is measured and stored in the microprocessor, so that on subsequent movements, the gate can open and close to precisely the open and closed positions without stopping short of or banging into such end positions. The motor mechanism of the operator is pulsed during the certain opening movements and closing movements and portions thereof. In this way, in the event of any bottoming out of the extensible and retractable arm against the end of the worm shaft, damage to the operator will not result.

    摘要: A stop range setting circuit (1) sets a stop range of a control object on the basis of a target position signal, and a PBR (6) detects a present position of the control object driven by a motor (5). The comparison circuit (2) compares the present position of the control object with the set stop range, and outputs an out-of-stop range signal (e) and a rotating direction indication signal (f) until the control object reaches the stop range. The out-of-stop range signal (e) is input to a drive start determination circuit (3), and a drive permission signal (g) is output to a drive circuit (4) when the out-of-stop range signal (e) is continuously output for at least a predetermined period of time. The drive circuit (4) drives the motor (5) in a direction indicated by the rotating direction indication signal (f) while the drive permission signal (g) is continuously output, so that an instantaneous ON/OFF signal is not input to the drive circuit (4) in the presence of external noise.

    摘要: A method of controlling a servomotor adapted to accelerate the convergence of deviations of position and speed, having excellent response and a high resistance to disturbance and free from mechanical resonance. When a torque command Tc1 obtained by a conventional speed control operation is small, a regulating gain G is increased, and, when this torque command is large, the regulating gain G is reduced (S1-S3). A torque Tc2 obtained by multiplying a Tc1, an output from a speed control unit by this regulating gain G is used as a torque command to be supplied to a servomotor (S4, S5). When deviations of position and speed and a torque command Tc1 are small, the gain becomes high, so that the response is improved and the convergence of these deviations is effected more speedily. When a torque command Tc1 is large, the gain is low, and mechanical oscillation does not occur.

    摘要: An automatic offset adjusting apparatus (4) for current detectors (5, 11) in a digital controller for a servo motor (10) is constructed so that, when errors occur in offset correction values (c1, c2) due to a temperature change and the like while the servo motor (10) is in operation, an electrical angle detecting unit (26) detects a ripple of the torque of the servo motor (10), on the basis of a ripple of a torque command value (b), and detects a first electrical angle, where the torque command value (b) becomes maximum, and a second electrical angle, where the torque command value (b) becomes minimum, based on an electrical angle signal (f) of the servo motor, a judgement unit (27) judges whether or not offset correction errors have occurred on the basis of a difference between the first and second electrical angles, and, if the judgement unit (27) judges that the offset correction errors have occurred, a correction unit (30) adds adjustment values for the offset correction values (c1, c2) corresponding to the first electrical angle to the respective offset correction values (c1, c2) to update the offset correction values (c1, c2), whereby the correction of the offset correction values (c1, c2) is automatically carried out even while the servo motor (10) is in operation, thereby preventing generation of the ripple of the torque of the servo motor (10).

    摘要: A multiplier ratio DMR is calculated in advance by an operation unit (20) based on the moving amount (L) of a mechanical moving part per turn of the motor, moving amount (R) per pulse of moving instruction, and the number (N) of incremental pulses generated in an absolute position detect pulse coder (18) per turn of the motor. Moving instructions (DELTARn) are integrated by a moving instruction integration unit (11), the absolute position (PA') of a machine produced from the absolute position detect pulse coder (18) is multiplied by DMR times, a difference (Er) between an integrated value (Pc) of moving instruction and a multiplied result (PA) is calculated as a positional error, and the rotation of the servo motor (17) is controlled based on the positional error.

    摘要: A method and apparatus for prediction repetition control of a servo motor which can converge a position error to zero even for an instruction repeated in a predetermined cycle and containing asynchronous components out of synchronism with this cycle. A repetition controller (5) and a feed-forward controller (6) equivalent to the inverse system of a control object (4) are disposed in parallel inside a servo control system of a servo motor. The feed-forward controller (6) consists of an FIR type digital filter and receives a future instruction P ahead by the order N of the control object. A coefficient of the filter is decided so that the feed-forward controller (6) itself becomes an inverse system by the inputted instruction P and the position error ε. Because the transfer function of the feed-forward controller (6) becomes the reciprocal of the transfer function of the control object, the transfer function of the output φ for the instruction P becomes [1]. Therefore, the position error does not exist, in principle, and can be minimized.
