Abstract
There are provided servo motors and servo control units for n shafts. A setting device previously sets parameters for servo control individually for each of the n shafts and previously sets parameters for servo control for a synchronizing operation. Data which determines synchronization conditions of servo motors of respective shafts is applied, when required, by an input device independently of setting by the setting device. The data which determines the synchronization conditions includes, for example, data of combination of synchronized shafts and data of section for synchronization. A moving pattern preparation device determines servo motor shafts to be synchronously controlled on the basis of the synchronization condition determining data applied through the input device and prepares a moving pattern to a target position on the basis of the parameters for servo control set by the setting device with respect to each servo motor shaft to be synchronously controlled. Positioning control data corresponding to the prepared moving pattern is supplied to the servo control unit corresponding to each shaft to synchronously control the servo motor corresponding to each shaft. The synchr…
