An operation control device for controlling an operation of a manufacturing system including an industrial machine using drive signals of at least two lineages, the device comprising a first drive signal output unit for outputting a first drive signal as a drive signal of a first lineage, a second drive signal output unit for outputting a second drive signal as a drive signal of a second lineage, a synthesized drive signal generation unit for generating a synthesized drive signal by synthesizing the first drive signal and the second drive signal, and an operation control unit for controlling an operation of the manufacturing system on the basis of the first drive signal, the second drive signal, and the synthesized drive signal.

Abstract: A controller that can perform high-precision synchronous control even when the speed of a master axis changes and a machine learning device are provided.

Abstract: A numerical controller contains a position table where a positional relationship is defined between a position of a master axis and positions of a plurality of slave axes, a slave axis synchronous control unit that drives and controls the plurality of slave axes in accordance with the position table so that the slave axes are synchronized with the master axis, a parent determining unit that determines one slave axis, which is stopped due to a failure, to be a parent of the master axis, and a master axis control unit that drives and controls the master axis based on a command position, and if a slave axis serving as the parent of the master axis is determined by the parent determining unit, drives and controls the master axis in accordance with the position table, so that the master axis is synchronized with the slave axis determined to be the parent.

Abstract: A master unit that controls a master axis and a slave unit that controls a slave axis are connected via a communication path to construct a numerical control system. The slave unit acquires a reception time of synchronization information received from the master unit and records a history of the reception time of the synchronization information. Then, when retransmission of transfer of the synchronization information is detected, the slave unit corrects the reception time of the synchronization information based on history data of the reception time and corrects asynchronous position of the slave axis based on a corrected reception time.

Abstract: A numerical controller outputs a position command corresponding to a synchronous position in consideration of a servo delay of a slave axis, to the slave axis from a real position of a master axis, in order to perform position control of the slave axis, thereby making a real position of the slave axis synchronously follow the real position of the master axis. A position control gain of the slave axis is changed based on a predetermined physical quantity during the synchronous control and a compensation value for the position command for the slave axis is varied depending on the amount of change of the position control gain of the slave axis.

Abstract: When a numerical controller is notified of switching to pressure control during instructing of position-controlled synchronization, the numerical controller places the synchronization instruction in pause and switches to a pressure-controlled instruction. Then, when it is desired to return from pressure control to position control, a transition from pressure control to position control is effected by resuming the position-controlled synchronization instruction that has been placed in pause hitherto and outputting movement instructions up to the actual position all at once. With this, the actual speed matches the position-controlled speed controlled by the servo control section, thereby reducing a shock at the time of switching from pressure control to position control.
