Abstract: front page image
(EN)Disclosed is an encoder system equipped with: a first encoder that is a single rotation absolute type and that outputs a first signal according to the angular position of a first rotatable axis; a power transmission device that transfers the power of the first axis to a second rotatable axis with a prescribed transmission ratio; a second encoder that is a single rotation absolute type and that outputs a second signal according to the angular position of the second axis; and a signal-processing unit that generates data related to the quantity of rotation of the first axis based on at least the first signal and the second signal.
(FR)L'invention concerne un système de codeur comprenant: un premier codeur du type absolu à rotation unique qui produit un premier signal selon la position angulaire d'un premier axe rotatif; un dispositif de transmission de puissance qui transfère la puissance du premier axe vers un deuxième axe rotatif selon un rapport de transmission prescrit; un deuxième codeur du type absolu à rotation unique qui produit un deuxième signal selon la position angulaire du deuxième axe; et une unité de traitement de signal qui produit des données relatives à la valeur de rotation du premier axe sur la base du premier signal et du deuxième signal au moins.
(JA) エンコーダシステムは、回転可能な前記第1軸の角度位置に応じた第1信号を出力する1回転アブソリュート型の第1エンコーダと、前記第1軸の動力を回転可能な第2軸に所定の伝達比で伝える動力伝達装置と、前記第2軸の角度位置に応じた第2信号を出力する1回転アブソリュート型の第2エンコーダと、少なくとも前記第1信号と前記第2信号とに基づき、前記第1軸の回転数量に関するデータを生成する信号処理部と、を備える。
