摘要： A CPU unit of a PLC executes a motion control and a sequence control. The CPU unit stores a CAM table and a control program for performing the motion control using the CAM table. When a microprocessor receives a command for altering one of a plurality of phases and/or a displacement associated with the phase, the microprocessor alters the phase and/or the displacement in the CAM table to a value that is on the basis of the command. When the microprocessor performs the alteration, the microprocessor executes a control program using a post-alteration CAM table, and outputs the execution results to an apparatus to be controlled.

摘要： A numerical controller capable of operating an auxiliary function at a target time or spindle position in performing operation based on table format data. An auxiliary function table is stored with auxiliary function commands M to be outputted corresponding to commanded reference times Lc and their corresponding operation delay times D. A reference time L is updated based in accordance with an override value. An auxiliary function command M and its corresponding operation delay time D are read from the auxiliary function table. The delay time D is corrected with the override value, and a reference time prior to a commanded reference time Lc by a margin equivalent to the corrected delay time is set as a command time Lr. If an override is entered, the delay time is corrected for the override amount and modified into an overridden reference time unit, and a command time for an auxiliary function is obtained and outputted based on the reference time unit. Thus, the auxiliary function is performed appropriately at a commanded value Lc of the reference time.

摘要： A machine tool and a control method therefor providing an improved machining accuracy even when a numerical control and electronic cam control coexist. The CPU determines the moving position of the workpiece, the tool, and the drilling tool according to the command from each channel machining sequence storage portion, and outputs the determined position as a command signal in response to the pulse signal generated at the pulse signal generating circuit. The workpiece, the tool, and the drilling tool are thereby electronic cam controlled. The CPU also determines the moving position of the workpiece and the tool according to the command from each channel machining sequence storage portion, and outputs the determined position as a command signal in response to the divided timing signal generated at the divided timing signal generating circuit. The workpiece and the tool are thereby numerically controlled.

摘要： A synchronous control apparatus capable of switching cam curves with ease and without delay is provided. A cam curve storing unit stores a representation of a first cam curve and a representation of a second cam curve. Before switch-over of the cam curves, a control unit finds a position command value to a driven-side member, after the switch-over of the cam curves, the control unit finds the position command value, and in a switch-over period of the cam curves, the control unit finds the position command value to the driven-side member based on a value obtained by utilizing first data based on the first cam curve or a position of the driven shaft and second data based on the second cam curve to provide a weighted average at each control timing.

摘要： A position is obtained from a command movement for a controlled axis. The position of a virtual axis with respect to time and an I/O signal are obtained. The position of the controlled axis and the state of the I/O signal are stored in association with the position of the virtual axis, and cam shape data and I/O signal state data are obtained. During an electronic cam operation, the virtual axis position is controlled by means of virtual axis control means. Corresponding to the position of the virtual axis, the position of the controlled axis or the I/O signal state is read from the cam shape data and the I/O signal state data and outputted, whereby the controlled axis is driven.

摘要： A reference variable having a linear relationship with the angular position of a master axis is set, and a correspondence between this reference variable and the displacement of a slave axis is stored in a data table. One execution stage is specified by setting a starting reference variable and an ending reference variable from this data table. A desired sequence is assigned to a plurality of execution stages thus specified. The reference variable corresponding to the angular position of the master axis is determined, slave axis displacement data corresponding to the reference variable is read out, and the slave axis is positioned in accordance with the position of the master axis on the basis of this displacement data.
