Title (EN) ENCODER HAVING ABNORMALITY DETECTION DEVICE AND ITS CONTROL SYSTEM THEREOF
(FR) CODEUR AVEC DISPOSITIF DE DÉTECTION D’ANOMALIE ET SON SYSTÈME DE CONTRÔLE
(JA) 異常検出装置付きエンコーダおよびその制御システム
Abstract:
(EN) An encoder having an abnormality detection device can quickly and reliably detect an abnormality of the encoder even if the abnormality occurs at the power source of an encoder circuit. Different power sources are used for an encoder circuit (30) and an abnormality detection device (40). An analog signal A indicating the signal state at each part of the encoder and used for detecting an abnormality of the encoder is input to an abnormality detection circuit (41) from the encoder circuit (30). The abnormality detection circuit (41) detects whether the level of the analog signal is within a preset and predetermined range or not. If the abnormality detection circuit (41) detects that the level of the analog signal is outside the predetermined range, it generates an abnormality signal and sends it to an abnormality signal transmission circuit (42).
(FR) La présente invention concerne un codeur avec dispositif de détection d’anomalie qui peut détecter rapidement et de manière fiable une anomalie du codeur même si l’anomalie se produit à la source d’alimentation d’un circuit codeur. Différentes sources d’alimentation sont utilisées pour un circuit codeur (30) et un dispositif de détection d’anomalie (40). Un signal analogique A indiquant l’état de signal de chaque partie du codeur et employé pour détecter une anomalie du codeur est fourni à un circuit de détection d’anomalie (41) du circuit codeur (30). Le circuit de détection d’anomalie (41) détecte si le niveau du signal analogique appartient ou non à une plage préréglée et prédéterminée. Si le circuit de détection d’anomalie (41) détecte que le niveau du signal analogique est hors de la plage prédéterminée, il génère un signal d’anomalie et l’envoie à un circuit de transmission de signal d’anomalie (42).
(JA)  エンコーダ回路の電源に異常が発生しても、エンコーダの異常を速やかに確実に検出できる異常検出装置付きエンコーダを提供する。  エンコーダ回路(30)への電源と異常検出装置(40)への電源は別電源を用いる。エンコーダ回路(30)から異常検出回路(41)に、エンコーダの異常状態を検出するためのエンコーダ各部の信号の状態を示すアナログ信号Aが入力されており、異常検出回路(41)はこのアナログ信号のレベルが予め設定した所定の範囲内であるかどうかを検出する。所定の範囲外であることが検出されると異常信号を生成し、異常信号送信回路(42)に入力する。
