Synchronization control method and synchronization control device

A synchronization control device for a machine having a master axis and a slave axis positioned to a position corresponding to the position of said master axis, comprising:

• storing means for registering displacement data for said slave axis;
• specifying means for specifying a plurality of execution stages each constituted by a desired portion or the entirety of said displacement data, and specifying a desired order for the plurality of execution stages thus specified;
• and
• means for positioning the slave axis in accordance with the position of the master axis, which changes moment by moment, on the basis of the displacement data in said specified execution stages.

A synchronization control device for a machine having a master axis and a slave axis positioned to a position corresponding to the position of said master axis, comprising:

• a data table DT for setting a reference variable x having a linear relationship with the angular position θ of the master axis, and storing a correspondence between said reference variable x and the slave axis displacement y;
• execution stage specifying means for freely specifying an individual execution stage by setting a starting reference variable x and an ending reference variable x from said data table;
• means for allocating a sequence to a plurality of execution stages specified by said execution stage specifying means;
• and
• slave axis displacement command reading means for reading out a command for displacing the slave axis from a slave axis displacement y corresponding to said starting reference variable x to a slave axis displacement y corresponding to said ending reference variable x, in accordance with said data table DT, in the period in which the master axis rotates from an angular position θ corresponding to the starting reference variable x in one execution stage allocated with a desired sequence, to an angular position θ corresponding to the ending reference variable x thereof.
