Abstract: A controller includes a calculator, a generator, and an adjuster. The calculator calculates a correction value for a position command based on a transmission delay and a control delay included in outputting the position command from the controller to the slave axis drive. The transmission delay is a delay in transmitting the position command to the slave axis drive. The control delay is a delay in the slave axis drive. The generator generates a corrected position command by applying the correction value to a reference position command for the slave axis drive calculated using position information about the master axis drive. The adjuster adjusts, in a predetermined period from when a speed of the master axis drive changes, the correction value to be below a value calculated by the calculator to cause a position of the slave axis drive to avoid exceeding a position of the master axis drive.

Abstract: A work machine for performing a predetermined task through electronic cam control causes a master axis and a slave axis to return to have the correlation following an electronic cam profile after stop of electronic cam control. A predetermined position, which is a position of a slave axis drive corresponding to a cam angle of the stopped master axis, is obtained based on an electronic cam profile in response to stop of synchronization control over a master axis drive and the slave axis drive performed in the work machine. In response to the stopped slave axis drive being determined to be at a position deviating from the predetermined position, a return path is calculated based on the predetermined position and an interference section, in a range of cycles for the slave axis drive, in which the slave axis drive interferes with the workpiece for the predetermined task.
