摘要: A reference point detection pulse generator determines normally-equidistant reference points which provide references over the whole control axis range of a numerically controlled machine. On the basis of the outputs of the reference point detection pulse generator and a moving amount detection pulse generator, the position of a moving part is numerically calculated by a moving part position calculator means. The position of the moving part based on the output of the moving amount detection pulse generator is compared with that based on the output of the moving part position calculator means, and if an error is present therebetween an alarm is issued.
