Start by telling the scheduler to stop its current cycle with the PowerShell cmdlet 

Stop-ADSyncSyncCycle

To initiate a full sync cycle, run

It could be that you have an urgent change which must be synchronized immediately which is why you need to manually run a cycle.

PS C:UsersAdministrator> Start-ADSyncSyncCycle -PolicyType Delta

PS C:UsersAdministrator> Get-ADSyncConnectorRunStatus
