摘要： A rotary encoder easily position-adjusted in relation to a rotary shaft and is reduced in accuracy deterioration attributable to rotational unstableness and the like which is caused after attachment to the rotary shaft. The encoder is a device attached to the rotary shaft to outputting signals with the rotation of the shaft. The encoder includes a rotary disk, a detector for detecting rotational position of the rotary disk, a disk holder for fixedly attaching the rotary disk to the rotary shaft, and a housing for fixing the detector such that the detector is opposed to the rotary disk. The encoder comprises a retainer attachable to and detachable from the disk holder and the housing for retaining positional relation between the disk holder and the housing.

摘要： In a control apparatus, a “characteristic value calculation” block calculates a characteristic value (such as amplitude value, offset value, or waveform distortion for each phase of two-phase sinusoidal signals optically input from an encoder, or phase difference between the two phase signals) for each of the two-phase sinusoidal signals, and an “alarm detection” block checks the presence or absence of an excursion outside a predetermined allowable range and, if such an excursion is detected, produces an alarm indication or the like. Each time the “present characteristic value” is input, a “characteristic value comparison” block compares it with “previous characteristic values”, and analyzes the result of the comparison. That is, the difference between the present value and each previous data is calculated, and the largest amount of variation (with plus or minus sign) is obtained; if this amount is larger than a predetermined value, a signal indicating an “imminent failure” is output. In an alternative method, the present value is compared with a characteristic value calculated from an encoder reference signal. Further, the characteristic value monitoring and comparison may be performed within the encoder. In this way, data useful for the prediction of encoder failure, etc. is provided.
摘要翻译：在控制装置中，“特征值计算”块计算从编码器光输入的两相正弦信号的各相的幅值，偏移值或波形失真或两相之间的相位差的特征值信号），并且“报警检测”块检查在预定允许范围之外的偏移的存在或不存在，并且如果检测到这样的偏移，则产生报警指示等。每当输入“当前特征值”时，“特征值比较”块将其与“先前特征值”进行比较，并分析比较结果。也就是说，计算当前值和每个先前数据之间的差异，并且获得最大的变化量（具有加号或减号）; 如果该量大于预定值，则输出表示“即将发生故障”的信号。在替代方法中，将当前值与从编码器参考信号计算的特征值进行比较。此外，可以在编码器内执行特征值监视和比较。以这种方式，提供了用于预测编码器故障等的数据。

摘要： The invention aims to reduce an error occurring due to the mounting condition of an acceleration sensor. In the case of a two-axis sensor, an angle θ is calculated from outputs (x′, y′) that the acceleration sensor produces when known accelerations (x, y) are applied, and the angle θ is stored in a storage device contained in a casing in which the acceleration sensor is housed. In the case of a one-axis sensor, the ratio of the magnitudes of accelerations is stored. The acceleration detected by the acceleration sensor is compensated by using the value stored in the storage device.

摘要： A rotary disc for use in a rotary encoder includes a signal generation section having a pattern formed thereon to generate a signal indicative of a rotational angle/phase. The signal generation section has a peripheral surface, which is provided with a linear portion usable as an indicator indicative of the rotational angle/phase represented by the signal generation pattern on the signal generation section. A robot hand is employed to hold the linear portion and attach it through an attachment portion of the rotary disc to a rotor shaft of a motor.
