Abstract

PURPOSE:To simplify a control circuit and a control software in multi-shaft controller by furnishing a control means to control start, stop, and acceleration/ deceleration of different drive shafts of each device itself according to control information read out of a data table every time the positions of the drive shafts of each device vary. CONSTITUTION:Memories 16, 26 to which the CPUs of an F-side device 10 and an L-side device 20 have access, are previously set as a four-dimensional data table using parameters consisting of the locational information as L-sagital, F-sagital, L-oblique, F-oblique, and each CPU or microcomputer reads at all times the data of F-oblique, L-oblique, F-sagital, L-sagital as control data corresponding to the current positions of an F-C arm 10 and L-C arm 20. On the basis of the read data. microcomputer 14 for ex. of the F side CPU gives a message 'emit low speed command of F-oblique move to a motor controller 18 if bit of F-oblique is standing' and implements the control.
