20080224693 | ABNORMALITY DETECTION APPARATUS FOR ROTARY TYPE ABSOLUTE ENCODER - In order to cope with many rotor diameters using a single type of stator portion, two stator portions, each having a built-in signal processing circuit for detecting absolute positions independently, are disposed in opposition at positions which differ from each other with respect to a rotational center of a rotor portion. When one of the stator portions receives a request command RX from an external device, it transmits a detected serial communication signal. The other stator portion receives the transmitted serial communication signal, determines a position detection abnormality, and notifies the abnormality to the external device when a difference between the received absolute position and the absolute position detected by the other stator portion exceeds a deviation previously set for 180 degrees. | 09-18-2008 |
20080228423 | POSITION DETECTOR - Two position sensors provide, as outputs, two signals that vary sinusoidally at a pitch of wavelength λ with respect to a displacement of a target and have phases shifted from each other by 90°. A memory unit has stored therein offset values for the two signals, and two subtractors eliminate the offset values from the two signals, respectively. The two signals after offset elimination are converted into position data in an interpolation calculator. A radius calculator calculates a radius value of the two signals after offset elimination. An FFT calculates offset values based on the position data and the radius values, and the calculated offset values are used to update the values stored in the memory unit. An amplitude ratio correction value and a phase difference correction value for the two signals are updated similarly. By performing elimination of the components that degrade interpolation accuracy at every rotational position, interpolation accuracy is improved. | 09-18-2008 |
