Abstract
(EN)
A synchronous control device (10) comprises: a spindle control unit (11a); and a driven shaft control unit (11b) including a driven shaft command position variation suppression unit (114) for generating, in a case where the sign spindle speed is inverted from a previous period, an intended driven shaft command phase obtained by adding an advancing amount (Pa) corresponding to the spindle speed to a spindle phase (Pm) as a driven shaft command phase (Ps), and generating, in a predetermined case where the sign of the spindle speed is not inverted before a previous period, a value with which the sign of a transition from the driven shaft command phase in the previous period is not inverted from the sign of the spindle speed as the driven shaft command phase (Ps).
(FR)
La présente invention concerne un dispositif de commande synchrone (10) comprenant : une unité de commande d'axe (11a) et une unité de commande d'arbre entraîné (11b) comprenant une unité de suppression de variation de position de commande d'arbre entraîné (114) pour générer, dans un cas où le signe de la vitesse d'axe est inversé par rapport à une période précédente, une phase de commande d'arbre entraîné prévue obtenue par addition d'une quantité d'avance (Pa) correspondant à la vitesse d'axe à une phase d'axe (Pm) comme phase de commande d'arbre entraîné (Ps), et à générer, dans un cas prédéterminé où le signe de la vitesse d'axe n'est pas inversé avant une période précédente, une valeur avec laquelle le signe d'une transition de la phase de commande d'arbre entraîné dans la période précédente n'est pas inversé par rapport au signe de la vitesse d'axe comme phase de commande d'arbre entraîné (Ps).
(JA)
同期制御装置(10)は、主軸制御部(11a)と、主軸速度の正負が前の期間から反転する場合には、主軸位相(Pm)に主軸速度に応じた進角量(Pa)を加算した予定従軸指令位相を従軸指令位相(Ps)として生成し、主軸速度の正負が前の期間から反転しない所定の場合には、前の期間における従軸指令位相からの偏移の正負が主軸速度の正負から反転しない値を従軸指令位相(Ps)として生成する、従軸指令位置変動抑制部(114)を有する従軸制御部(11b)を備える。
