Spindle Synchronization
Chapter 15
15-4
The following example shows the value at which the follower spindle
ramps to when:
No overlap occurs between the controlling and follower spindles’
gear ranges
The controlling spindle has a higher gear range than the follower
spindle
The controlling spindle has a lower gear range than the follower
spindle

If the external load is on the follower spindle, the controlling spindle will
not try to adjust to following spindle’s velocity or velocity and position
during synchronization. This action returns a $SYNE error, identified by
PAL. Refer to your PAL manual for more information on the $SYNE flag.
