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.

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 synchronous controller capable of easily controlling a slave axis in synchronism with a master axis performing a composite motion of a plurality of axes. Motion commands for two axes X, Y constituting the master axis are subject to interpolation/distribution and acceleration/deceleration processing, to determine distribution motion amounts, and the determined amounts of motion of the two axes X, Y constituting the master axis for every interpolation period are combined to determine an amount of motion M of the master axis, from which is determined an amount of motion of the slave axis for every interpolation/distribution period. The determined amounts of motion of the X, Y and slave axes are output to respective servo control means, thus driving the respective axes. In case the master axis is constituted by a means driven by external X and Y axes, amounts of motion of the external X and Y axes for every predetermined period are detected by detectors, and used, instead of the distribution motion amount, to determine an amount of motion M of the master axis from which an amount of motion of the slave axis is determined to drive the slave axis.
