Spindle Synchronization Control Ii - Mitsubishi Electric MELDAS C6 Programming Manual

10. Spindle Functions

10.8 Spindle synchronization control II

Function and purpose
In a machine having two or more spindles, this function controls the rotation speed and phase of
one spindle (synchronous spindle) in synchronization with the rotation of the other spindle (basic
spindle).
The function is used if a workpiece grasped by the basic spindle is to be grasped by a synchronous
spindle, or if the spindle rotation speed has to be changed when one workpiece is grasped by both
spindles.
With the spindle synchronous control II, selection of the spindles and synchronization start, etc.,
are all designated from the PLC.
Basic spindle and synchronous spindle selection
Select the basic spindle and synchronous spindle for synchronous control from the PLC.

10.8 Spindle synchronization control II
Explanation
Select a serially connected spindle to be
controlled as the basic spindle.
(0: 1st spindle), 1: 1st spindle, 2: 2nd spindle,
... , 7: 7th spindle
(Note 1) Spindle synchronization control will
not take place if a spindle not
connected in serial is selected.
(Note 2) If "0" is designated, the 1st spindle will
be controlled as the basic spindle.
Select a serially connected spindle to be
controlled as the synchronous spindle.
(0: 2nd spindle), 1: 1st spindle, 2: 2nd spindle,
... , 7: 7th spindle
(Note 3) Spindle synchronous control will not
take place if a spindle not connected
in serial is selected or if the same
spindle as the basic spindle is
selected.
(Note 4) If "0" is designated, the 2nd spindle
will be controlled as the synchronous
spindle.
