摘要： After cyclic original signals generated from a sensing element of an encoder are converted into digital signals, positions P(0) to P(n) in one period are obtained for each given period by means of a digital interpolator. If position data obtained immediately after a zero cross point is detected are P(0) and P(n) and if speed is fixed, an object should move on a straight line from a position P(0) to a position P(n). An actual detected position data P(m) is deviated from this straight line by D(m). This detection error D(m) and the detected position data P(m) are combined and stored in advance as reference data, and correction is carried out using the reference data every time position data is detected by the digital interpolator.

摘要： A driving control apparatus that can judge whether there is any abnormality in the operation of an acceleration sensor as well as in the mounting direction thereof. The driving control apparatus which controls the operation of a driven part via a driving device is constructed to include an abnormality judging circuit which, based on acceleration information from the acceleration sensor, judges the presence or absence of an abnormality in the operation of the acceleration sensor, or the mounting thereof with respect to the driven part, in addition to a position sensor or velocity sensor which detects the position or velocity of the driven part and the acceleration sensor which detects the acceleration of the driven part separately from the position sensor or velocity sensor. When judging information supplied from the abnormality judging circuit indicates the presence of an abnormality, the operation of the driven part is controlled, without using the acceleration information from the acceleration sensor, based on the position or velocity detected by the position sensor or velocity sensor.

摘要： An industrial machine in which vibration exerted on a position detector provided for an axis of the machine is detected and countermeasures against the vibration can be swiftly taken. A ball screw is driven by a servo motor MZ supplied with power from a servo amplifier via a power line so that a cutting unit is advanced and retracted. A spindle motor MS above the cutting unit rotates a cutting tool via a spindle shaft and a workpiece W on an XY table is machined. An acceleration detection element is built in a position detector attached to a motor shaft of the servo motor MZ. An angle detection signal for servo control and a vibration level signal outputted by the acceleration detection element are converted into serial signals and are transmitted to a controller (axis control circuit of Z-axis) via the common signal line. The controller takes measures of changing the machining condition (for example, change of spindle rotational speed) and stopping the machine in accordance with a rank of the vibration. A duration or total time period of the abnormal vibration may be monitored.

摘要： An encoder that can detect the presence of noise occurring within the encoder. The encoder is constructed by incorporating within the same apparatus: a movement detecting unit for detecting the movement of a moving body; a signal processing circuit for processing a movement detection signal supplied from the movement detecting unit, and thereby producing an encoder signal representing the position and/or the amount of displacement of the moving body; and a noise detecting unit for detecting noise superimposed on the movement detection signal. According to this encoder, a noise voltage generated within the encoder via a stray capacitance is detected within the encoder and is output as noise data, so that the noise level can be detected without requiring the use of an external measuring device. Further, by outputting encoder data and noise data occurring at the same instant in time, the reliability of the encoder data can be judged based on the condition of the noise level.

摘要： In an encoder which is equipped with two detectors arranged on both sides of a rotating shaft in order to eliminate an eccentricity error, the mounting of the detectors is facilitated by making provisions so as to not cause a problem in the calculating of an average even if the detectors happen to be so mounted that the difference between the angular values calculated from the outputs of the respective detectors becomes equal to 180°. In an initialization process after power on, the difference Δθ between the angular values θ1 and θ2 calculated from the signals output from the respective detectors is stored as an initial value. Position data θ is output by taking an average between θ3 and θ2, where θ3 is a value obtained by correcting θ1 by the initial difference Δθ.
