13.14 Multiple Spindle Synchronization Set Control

13.14.2 Function Enabling Conditions

 This function can be applied to a lathe system equipped with two or more spindles.
 To enable this function, set the parameter "#1440 multi_sp_syn (Multiple spindle synchronization valid)" to "1".
(After setting the parameter, turn OFF and ON the NC power.)
If the parameter "#1440 multi_sp_syn (Multiple spindle synchronization valid)" is set to "0", multiple spindle synchronization
commands cannot be issued. (If two or more spindle synchronization commands are given, the operation error (M01 1005)
occurs, which stops the automatic operation.)
Note that guide bushing spindle synchronization is not included in the multiple spindle synchronization sets.

13.14.3 Precautions

While the multiple spindle synchronization set control is OFF, the control uses the input/output signals of the 1st spindle.
While the multiple spindle synchronization set control is ON, the control uses the signals of the synchronized (or
superimposed) spindle for Spindle synchronization control, Tool spindle synchronization control IA (polygon) or Spindle
superimposition control, or the signals of the hob (reference) spindle for Tool spindle synchronization II (hob).
(Example 1) The PLC interface signals that are used when "G114.1H2D5" is commanded
 While the multiple spindle sync set control is OFF, the control uses the I/O signals of the 1st spindle.
 While the multiple spindle sync set control is ON, the control uses the I/O signals of the 5th spindle.
(Example 2) The PLC interface signals that are used when "G114.1H3D9" is commanded
 While the multiple spindle sync set control is OFF, the control uses the I/O signals of the 1st spindle.
 While the multiple spindle sync set control is ON, the control uses the I/O signals of the 3rd spindle.
