Abstract: Feedback is provided, based on an actual drive amount of an actuator, to a command to a subsequent actuator. A control system includes a memory configured to store a program configured to generate a command related to a working position, a controller configured to execute the program, a first output unit configured to output a drive signal to a first drive portion, a second output unit configured to output another drive signal to a second drive portion, and a measurement unit configured to measure a drive amount of the first drive portion. The controller is configured to extract a low-frequency component included in the command, transmit the low-frequency component to the first output unit, correct a high-frequency component included in the command based on a signal indicating the drive amount of the first drive portion, and transmit the high-frequency component to the second drive portion.

Abstract: A controller for performing synchronization control over the master axis and the slave axis to follow an electronic cam profile includes a reference position calculator that, in response to power being restored after a power disconnect, obtains a position of the master axis and calculates reference positions of the master axis and the slave axis based on the obtained position of the master axis, a position of the master axis at cam synchronization, and the electronic cam profile, and a return control unit that performs return control to determine a position of the slave axis corresponding to a current position of the master axis based on the current position of the master axis, the electronic cam profile, and the reference positions of the master axis and the slave axis calculated by the reference position calculator, and that moves the slave axis to the determined position.

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.
