Title (EN) ENCODER ABNORMALITY DETECTION METHOD
(FR) PROCÉDÉ DE DÉTECTION D'ANOMALIE DE CODEUR
(JA) エンコーダの異常検出方法
Abstract:
(EN) A robot is provided with a motor and an encoder for detecting the rotational position of the motor, wherein a controller outputs a speed command instructing the rotational position of the motor and outputs command position information to a safety unit for detecting an encoder abnormality, said command position information indicating the motor rotational position according to the speed command. Whereas the origin information of the motor is changed and the changed origin information is held in the controller as new origin information, when the origin information before the change is held in the safety unit, the controller sends the command position information generated on the basis of the origin information before the change to the safety unit.
(FR) L'invention concerne un robot pourvu d'un moteur et d'un codeur permettant de détecter la position de rotation du moteur, un dispositif de commande produit une commande de vitesse ordonnant la position de rotation du moteur et délivre des informations de position de commande à une unité de sécurité pour détecter une anomalie de codeur, lesdites informations de position de commande indiquant la position de rotation du moteur en fonction de la commande de vitesse. Alors que les informations d'origine du moteur sont modifiées et que les informations d'origine modifiées sont conservées dans le dispositif de commande en tant que nouvelles informations d'origine, lorsque les informations d'origine avant le changement sont conservées dans l'unité de sécurité, le dispositif de commande envoie les informations de position de commande générées sur la base des informations d'origine avant le changement à l'unité de sécurité.
(JA) モータ及びモータの回転位置を検出するエンコーダを備えたロボットにおいて、コントローラは、モータの回転位置を指示する速度指令を出力するとともに、速度指令に応じたモータの回転位置を示す指令位置情報をエンコーダの異常を検出するセーフティユニットに出力する。モータの原点情報が変更されて、コントローラに新たな原点情報として保持される一方、セーフティユニットに変更前の原点情報が保持されている場合に、コントローラは、変更前の原点情報に基づいて生成された指令位置情報をセーフティユニットに送信する。
