Embodiment Construction

[0034] based on Figure 1 ~ Figure 4 An application example of the control device of the embodiment will be described. figure 1 The upper section (a) of is a schematic configuration diagram of a control system including the control device. This control system has a network 1 , a servo driver 4 , and a standard PLC (Programmable Logic Controller: Programmable Logic Controller) 5 . The servo driver 4 is a servo control device for servo-controlling a device 6 having two motors 2 a and 2 b corresponding to two control axes. in addition, figure 1 The shown control system is configured so that two control axes (motors) can be driven by one servo driver 4, but instead of such a structure, one servo driver 4 is arranged for each control axis, and each servo driver 4 passes through Structure of network 1 connections. In addition, commands for synchronously controlling the two motors included in the device 6 are supplied from the standard PLC 5 to the servo driver 4 . This standard...

Abstract

The present invention eliminates synchronization deviation between a main shaft and a follower shaft and achieves suitable synchronous control of a main shaft drive device and a follower shaft drive device. This control device, which causes a main shaft drive device corresponding to a main shaft to synchronously control a follower shaft drive device corresponding to a follower shaft, comprises: a calculation unit that, in a step in which a command position is output from the control device to the follower shaft drive device, calculates a correction amount for the command position on the basis of transmission delay due to the transmission of the command position to the follower shaft drive device from the control device, and control delay in the follower shaft drive device; a generation unit that applies the correction amount to a reference command position for the follower shaft drive device calculated using position information for the main shaft drive device and generates a corrected command position; and an adjustment unit that adjusts the correction amount to be smaller than the value calculated by the calculation unit, so that the position of the follower shaft drive device does not exceed the position of the main shaft drive device during a prescribed period from when a speed change has occurred in the main shaft drive device.

Description

technical field [0001] The invention relates to a control device for synchronously controlling a main shaft driving device and a slave shaft driving device. Background technique [0002] As control of the operation of machines, equipment, etc., there is motion control for controlling the motion of motors, and this motion control includes various controls related to synchronous control of electronic cams, electronic gears, and the like. In such synchronous control, by realizing the synchronization between the main shaft and the slave shaft, desired work can be performed by the working machine including the main shaft driving device corresponding to the main shaft and the slave shaft driving device corresponding to the slave shaft. On the other hand, in synchronous control, due to the transmission delay until the information measured by the master master is processed and transmitted to the slave master, a synchronization misalignment may occur between the master master and the...
