  • Page 112.2.3 Synchronous control and composite control (1) Overview 3-path control has three independent control paths. For example, it can be used to control three turrets of a multiple-turret lathe independently. Machining is performed by a path 2 program. Z2 Turret 2 X2 Workpiece 1 Workpiece 2 Z1 Z3 X1
  • Page 12(2) Synchronous Control An axis in path 1 or path 2 can be synchronized with another axis in the same path or an axis in the other path. This is realized by issuing the same move commands for one axis (synchronous master axis) to another axis (synchronous slave axis). Using parameter SMRx (bit 0 of
  • Page 13(3) Composite Control Move commands can be interchanged between an axis in path 1 or path 2 and an axis in the other path. In other words, when a machining program is executed for one path, actual machining can be performed with an axis in the other path. Coordinate systems can also be switched auto
  • Page 14(4) Superimposed Control The superimposed control function adds the amount of movement of an axis (superimposed control master axis) to an axis (superimposed control slave axis) for which ordinary move commands are being executed. This function is similar to synchronous control but differs from it i
  • Page 15(d) Feedrate Because the amount of movement of the master axis is added to that of the slave axis, the resulting speed of the slave axis may become much more larger than a normal speed (such as rapid traverse speed specified in a parameter). To solve this problem, it is necessary to set feedrates th
