9.5.12 Restart operation of cam control
When the cam control is stopped during operation, a gap may be generated in the synchronous position
relationship 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.

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