Title:
【発明の名称】回転検出装置の断線検出方法
Document Type and Number:
Japanese Patent JP3071232
Kind Code:
B2
Abstract:
PURPOSE:To enable a discontinuity to be detected positively and constantly regardless of a rotary angle by using especially a DC voltage. CONSTITUTION:In a rotary detection device for converting an SIN wave signal 2 and a COS wave signal 3 from a rotary detector 1 to a digital angle signal 6a by an analog/digital converter 6, a DC voltage 12 is superposed on an SIN wave signal line 10 which outputs the SIN wave signal 2 and a COS wave signal line 11 which outputs the above COS wave signal 3 and a discontinuity state is detected by detecting the DC voltage 12.
