Function diagrams for marker synchronization

SyncStart to a running master after Power ON

If the slave is synchronized to a running master drive, the slave automatically synchronizes its position
to the master. After at least one slave marker and one master marker have been detected, the marker
compensation comes into effect.

Marker correction during operation

During operation, marker correction is always carried out when the markers is detected. This ensures
optimum synchronization, no matter whether the gear ratios are not accurate or there is a slip.
