CONTROL DEVICE AND METHOD OF SYNCHRONIZING CONTROL

摘要

To deal with the synchronization lag due to a delay on the second axis in a motion control system that synchronizes a first axis and a second axis. A control device includes a processor that uses position information for a first axis (real or virtual) to compute a position command for a second axis and provides an output to the second axis corresponding to the position command, whereby the control device synchronizes the second axis with the first axis. The processor corrects the position command to compensate for the synchronization lag caused by a delay due to a transmission of the command position to the second axis, and a delay on the second axis.
