2.3 Spindle speed control
2.3.1 General
3-path control has one spindle interface in each path, that is three interfaces as total. For
example, a work fixed at one or two spindles can be machined by three tool posts and power
tools in same time.
Each spindle interfaces (first spindle, second spindle, third spindle) is controlled by the
program command of each path independently. Which spindle is controlled by the program
of which path can be switched by the spindle command select signals (SLSPA, SLSPB). And
the spindle feedback select signals (SLPCA, SLPCB) can select which spindle sends the
feedback signal of the position coder to which path.
2.3.2 Details
(1) 1-spindle control, 2-spindle control, and 3-spindle control
In 3-path controlled lathe, the following spindle formation can be selected by the number of
spindle.
(a) 1-spindle control
Spindle interface belonging to path 1 is used.
(b) 2-spindle control (Parameter No.3703 2SP = 1)
Spindle interfaces belonging to path 1 and path 2 are used.
(c) 3-spindle control (Parameter No.3703 3SP = 1)
Spindle interfaces belonging to the all paths are used.
(2) Selecting the spindle command
Each spindle obeys the command of which path is selected by the spindle command select

  • 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

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).
