    • To achieve miniaturization of a resolver apparatus as a system, to obtain the resolver apparatus at a low cost, and to improve failsafe by installing an abnormality detection unit and a self-diagnosis circuit within the R/D converter. According to the present invention, an abnormality detecting method for an R/D converter in a resolver apparatus includes detecting abnormalities of at least the resolver itself (1), a cable wiring (2) through which the resolver (1) and the R/D converter (3) are connected to each other, and the R/D converter (3) itself by an abnormality detection unit (4) provided in the R/D converter (3).
    • 为了实现作为系统的分解器装置的小型化,以低成本获得分解器装置,并且通过在R / D转换器内安装异常检测单元和自诊断电路来改善故障安全。 根据本发明,解算装置中的R / D转换器的异常检测方法包括检测至少旋转变压器本身(1)的异常,电磁线(2),旋转变压器(1)和R / D转换器(3)彼此连接,并且R / D转换器(3)本身由设置在R / D转换器(3)中的异常检测单元(4)连接。
