12.1.12 Restart operation of cam control
When the cam control is stopped during operation, a gap is generated in the synchronization between the
main shaft and the driven shaft. To solve the gap, return the main shaft and the driven shaft to the
synchronization starting point and then start the synchronous operation.

(Note 1)
If the cam control stops during
operation, the synchronous
position relationship with the main
shaft is broken.
