Spindle Synchronization Control I; G114.1 - Mitsubishi Electric MELDAS C6 Programming Manual

10. Spindle Functions
10.7 Spindle synchronous control I; G114.1
Function and purpose
In a machine having two or more spindles, this function controls the rotation speed and phase of
one spindle (basic spindle) in synchronization with the rotation of the other spindle (synchronous
spindle).
The function is used "when the rotation speed of the two spindles must be matched, for example, if
a workpiece grasped by the 1st spindle is to be grasped by a 2nd spindle", or "if the spindle rotation
speed has to be changed when one workpiece is grasped by both the 1st and 2nd spindles".
With the spindle synchronous control function I, designation of spindles and controls start / stop of
synchronization are commanded using G codes in the machining program.
Command format
(1) Spindle synchronous control ON (G114.1)
This command designates the basic spindle and synchronous spindle, and synchronizes the
two designated spindles. By commanding the synchronous spindle phase shift amount, the
phases of the basic spindle and synchronous spindle can be aligned.

(2) Spindle synchronous control cancel (G113)
This command cancels the synchronous state of the two spindles rotating in synchronization
with the spindle synchronous command.
