Synchronizing controller
MG.10.N4.02 - VLT is a registered Danfoss trademark 49
Position synchronization (angle synchronization)
The position controller adjusts the slave drive position or angle to the master.
Figure 15: Control behaviour with position synchronization
It appears from the diagram that the control accuracy depends on the master acceleration and
on the speed deviation between slave and master. A typical application for this type of
synchronizing could be the replacement of a mechanical shaft. Or mixing controls where a
mixing rate is required.
The following example shows how embossing patterns on moulds is controlled. This application
requires accurate position control.
